Prices change; check the retailer before buying. Disclosure: https://homelabpicks.com/disclosure/ ## Verdict **[CyberPower CP1500PFCLCD](https://homelabpicks.com/go/cyberpower-cp1500)**: 1500VA/1000W with sine-wave output, 12 outlets, USB shutdown signaling, and user-replaceable batteries. The default tower UPS for a NAS, mini PC, and network stack. ## Measure first, then choose the protection path A UPS decision starts with the load you measure, the shutdown behavior you need, the physical format, and the manufacturer's runtime data for that exact model. - **[CyberPower CP1500PFCLCD](https://homelabpicks.com/go/cyberpower-cp1500)**: Tower UPS for a growing shelf lab. The default path for a NAS, mini PC, network gear, and USB-triggered graceful shutdown when a tower format fits. Constraint: Measure peak load, confirm active-PFC requirements, and check NUT's hardware list for the exact model. - **[APC BR1500MS2](https://homelabpicks.com/go/apc-br1500)**: Labs that standardize on APC. Choose APC when you already run APC hardware or software, or prefer APC's single-cartridge battery replacement. Constraint: Do not infer runtime from the 1500VA label. Check APC's runtime graph at your load. - **[Rack-mount UPS guide](https://homelabpicks.com/ups-power/best-rack-mount-ups/)**: Rails, 2U fit, or network management. Start here when the UPS must mount on four-post rails or needs a slot for a network management card. Constraint: Confirm usable rack depth, rail kit, unit weight, outlet type, the circuit it will share, and battery replacement access. - **[UPS sizing guide](https://homelabpicks.com/ups-power/how-to-size-ups/)**: Unknown load or runtime goal. Measure the complete protected load and choose from published runtime data before selecting a unit. Constraint: A portable power station with an EPS mode is not automatically a UPS. Verify transfer behavior with the protected hardware. ## Products ### Our Pick: [CyberPower CP1500PFCLCD](https://homelabpicks.com/go/cyberpower-cp1500) Our default tower UPS for a shelf, desk, or floor. CyberPower rates it at 1500VA/1000W with sine-wave output, AVR, 12 outlets, and a USB HID port that NUT lists under the usbhid-ups driver. It also has USB-A and USB-C charging ports and accepts an optional RMCARD205 network card. - Capacity: 1500VA / 1000W - Waveform: Sine wave (PFC Sinewave) - Outlets: 12: 6 battery + surge, 6 surge only - Battery: 2 × 12V/9Ah sealed lead-acid, user-replaceable - Runtime (CyberPower): 10 min at half load (500W), 2.5 min at full load - Interface: USB HID and dry contact; optional RMCARD205 card - Operating temperature: 32 to 104°F (0 to 40°C) Pros: - Sine-wave output suits active-PFC power supplies - 1000W rating leaves headroom for a growing lab - Listed in NUT's hardware compatibility list (usbhid-ups) - Tilting color LCD shows load, runtime estimate, and battery status - 3-year warranty that covers the batteries Cons: - Tower format; a rack needs a properly rated shelf - Short half-load runtime (CyberPower lists 10 minutes at 500W), so plan on a clean shutdown, not riding out long outages - Six of the 12 outlets are surge-only ### Best APC Option: [APC BR1500MS2](https://homelabpicks.com/go/apc-br1500) APC's sine-wave Back-UPS Pro tower. Choose it if you standardize on APC or prefer APC's single-cartridge battery replacement; its 900W rating is a little lower than the CyberPower's. - Capacity: 1500VA / 900W - Waveform: Sine wave - Outlets: 10: 6 battery + surge, 4 surge only - Battery: APCRBC163 cartridge, user-replaceable - Transfer time: 8 ms typical, 10 ms max - Charging ports: USB-A and USB-C - Typical recharge: 16 hours Pros: - Sine-wave output with AVR - USB-A and USB-C charging ports - Single APCRBC163 cartridge for battery swaps - APC lists a lifetime $500,000 equipment protection policy Cons: - 900W rating, 100W below the CyberPower CP1500PFCLCD - APC lists a 16-hour typical recharge, so a second outage soon after the first gets less runtime - Battery warranty is 1 year (UPS 3 years) - Not named individually in NUT's hardware list ### Budget Pick: [CyberPower CP850PFCLCD](https://homelabpicks.com/go/cyberpower-cp850) The smallest sine-wave unit in this guide. It suits a single NAS, or a mini PC and switch, whose peak load stays under about 340W, two-thirds of its 510W rating. - Capacity: 850VA / 510W - Waveform: Sine wave (PFC Sinewave) - Outlets: 10: 5 battery + surge, 5 surge only - Battery: 1 × 12V/9Ah sealed lead-acid, user-replaceable - Runtime (CyberPower): About 9 to 11 min at half load (255W), 2 to 3 min at full load - Interface: USB HID and dry contact Pros: - Sine-wave output for less money than the 1500VA units - NUT lists it under the usbhid-ups driver - Compact 3.9 x 9.7 x 10.2 in footprint Cons: - 510W rating leaves little room to grow - No USB charging ports listed - Single battery means shorter runtime than the 1500VA units ### Rack Mount: [APC Smart-UPS SMT1500RM2UC](https://homelabpicks.com/go/apc-smt1500rm2u) The rack option. APC's current 2U Smart-UPS in this class adds a SmartSlot for an optional network management card and a SmartConnect port for APC's cloud monitoring. It needs a four-post rack with at least 18.8 inches of usable depth. - Capacity: 1440VA / 1000W (sold as a 1500VA model) - Waveform: Sine wave - Outlets: 6 × NEMA 5-15R, all battery-backed - Form factor: 2U rack, 18.8 in deep, 58.4 lb - Rails: Rack mounting support rails included - Interface: USB, serial, SmartConnect port, SmartSlot - Battery: APCRBC133 cartridge Pros: - Rack mounting support rails included - SmartSlot for an optional APC network management card - SmartConnect Ethernet port for cloud monitoring - APC lists a 3-hour typical recharge Cons: - 58.4 lb; mount it at the bottom of a four-post rack - Only six outlets - Costs more than the tower units in this guide ### Long Runtime: [EcoFlow DELTA 2](https://homelabpicks.com/go/ecoflow-delta-2) A portable power station, not a traditional UPS. Its 1kWh-class LiFePO4 battery runs a typical home lab for hours, but its EPS switchover and lack of standard USB shutdown signaling mean you must test it with your hardware. - Battery: 1,024Wh LiFePO4, rated for 3,000+ cycles - AC output: 1,800W continuous (up to 2,200W with X-Boost) - Expansion: About 3kWh with one extra battery - Outage behavior: EPS auto-switch; not a zero-transfer online UPS - Shutdown signaling: EcoFlow app; no documented USB HID UPS interface - Warranty: 5 years (EcoFlow) Pros: - Hours of runtime at typical home-lab loads - LiFePO4 battery rated for 3,000+ cycles - Expandable with an extra battery - Doubles as portable emergency power Cons: - EPS switchover is not zero-transfer; test your power supplies - No documented USB HID interface for NUT - Not rack-mountable ## Comparison | Product | Capacity | Waveform | Outlets | Battery | Maker runtime (half load) | Form factor | Shutdown signaling | | --- | --- | --- | --- | --- | --- | --- | --- | | [CyberPower CP1500PFCLCD](https://homelabpicks.com/go/cyberpower-cp1500) (winner) | 1500VA / 1000W | Sine wave | 12 (6 battery + 6 surge) | 2 × 12V/9Ah SLA | 10 min at 500W | Mini tower | USB HID; optional RMCARD205 | | [APC BR1500MS2](https://homelabpicks.com/go/apc-br1500) | 1500VA / 900W | Sine wave | 10 (6 battery + 4 surge) | APCRBC163 cartridge | Runtime graph on APC's site | Tower | USB | | [CyberPower CP850PFCLCD](https://homelabpicks.com/go/cyberpower-cp850) | 850VA / 510W | Sine wave | 10 (5 battery + 5 surge) | 1 × 12V/9Ah SLA | About 9 to 11 min at 255W | Mini tower | USB HID | | [APC Smart-UPS SMT1500RM2UC](https://homelabpicks.com/go/apc-smt1500rm2u) | 1440VA / 1000W | Sine wave | 6 (all battery-backed) | APCRBC133 cartridge | Runtime graph on APC's site | 2U rack, 18.8 in deep | USB, serial, SmartConnect, SmartSlot | | [EcoFlow DELTA 2](https://homelabpicks.com/go/ecoflow-delta-2) | 1,024Wh / 1,800W | Pure sine wave | AC plus USB and DC outputs | 1,024Wh LiFePO4 | No UPS runtime chart | Portable power station | EcoFlow app; no USB HID | A UPS protects the shutdown path when utility power fails. Size it from the complete protected load and the manufacturer's runtime data, then confirm that every protected system receives the shutdown signal and finishes before the battery runs out. These picks are based on manufacturer datasheets, published runtime figures, form factor, and shutdown-integration support; the product cards above list each unit's key specs. If you already know your load, jump to [how to size a UPS](https://homelabpicks.com/ups-power/how-to-size-ups/). If the UPS will sit in a rack, read the [tower UPS shelf guide](https://homelabpicks.com/racks/best-rack-mount-ups-shelf/) before putting a heavy battery box on a shelf. ## Our Pick: CyberPower CP1500PFCLCD The [CyberPower CP1500PFCLCD](https://homelabpicks.com/go/cyberpower-cp1500) is our default tower UPS for a NAS, one or two mini PCs, a switch, and a router. CyberPower rates it at 1500VA/1000W with sine-wave output and automatic voltage regulation (AVR), which is the right starting point for active-PFC power supplies. Waveform alone does not prove compatibility with every PSU, so still test the installed setup. Read the runtime figures carefully. CyberPower lists 10 minutes at half load (500W) and 2.5 minutes at full load. A typical 80 to 150W lab runs much longer than the half-load figure, because lead-acid batteries deliver more of their capacity at low discharge rates, but plan around CyberPower's runtime chart at your own load rather than a rule of thumb. The USB port is a standard HID interface, and NUT's hardware compatibility list includes the CP1500PFCLCD under the usbhid-ups driver. CyberPower also lists an optional RMCARD205 card for SNMP and web monitoring, plus USB-A and USB-C charging ports. The tilting color LCD shows load and runtime estimates, which helps while you work out what your lab actually draws. The two 12V/9Ah batteries are user-replaceable, and CyberPower's three-year warranty covers them. Lead-acid batteries age whether or not they are used, so plan on a replacement every few years. **Buy it if:** your lab sits on a shelf, desk, or floor, draws well under the 1000W rating, and needs USB shutdown signaling for NUT, a NAS, or a hypervisor. **Skip it if:** you need a true 2U rack unit, your load can exceed about 650W (two-thirds of the rating) for long periods, or you need long outage runtime rather than a clean shutdown. For brand trade-offs, see [CyberPower vs APC](https://homelabpicks.com/ups-power/cyberpower-vs-apc/); for battery chemistry, see [LiFePO4 vs lead-acid UPS](https://homelabpicks.com/ups-power/lifepo4-vs-lead-acid-ups/). ## Best APC Option: APC BR1500MS2 The [APC BR1500MS2](https://homelabpicks.com/go/apc-br1500) is APC's sine-wave Back-UPS Pro tower: 1500VA/900W, AVR, 10 outlets (6 battery-backed), and USB-A plus USB-C charging ports. Choose it when you already standardize on APC hardware and software, or prefer APC's single-cartridge battery replacement (APCRBC163). Make sure you buy the sine-wave model. APC's smaller Back-UPS units, such as the BE600M1 and BVN650M1, output a stepped approximation of a sine wave on battery. The trade-offs are modest. The 900W rating is 100W lower than the CyberPower's, APC lists a 16-hour typical recharge time (CyberPower lists 8 hours for the CP1500PFCLCD), and APC's warranty covers the battery for one year and the UPS for three. APC publishes a runtime graph for this model on its product page; check it at your load before assuming the 1500VA label means long runtime. NUT supports APC Back-UPS Pro units through the usbhid-ups driver. The BR1500MS2 is not named individually in NUT's list, so confirm that your platform detects it. The apcupsd daemon also supports many APC USB models, but its last stable release dates to 2016, so NUT is the better default. ## Budget Pick: CyberPower CP850PFCLCD The [CyberPower CP850PFCLCD](https://homelabpicks.com/go/cyberpower-cp850) is the smallest sine-wave unit in this guide: 850VA/510W, 10 outlets (5 battery-backed), and a single 12V/9Ah battery. CyberPower's datasheet lists about 9 to 11 minutes at half load (about 255W) and 2 to 3 minutes at full load. It fits a single NAS drawing 40 to 60W, or a mini PC and switch around 80W. With the 1.5x sizing rule, keep its peak load under about 340W. If you expect to add a second NAS or a power-hungry server, the CP1500PFCLCD is the better long-term buy. NUT's hardware list includes the CP850PFCLCD under usbhid-ups. ## Rack-Mount Option: APC Smart-UPS SMT1500RM2UC The [APC SMT1500RM2UC](https://homelabpicks.com/go/apc-smt1500rm2u) is the rack pick. APC rates it at 1440VA/1000W (it is sold as a 1500VA model) with sine-wave output, six outlets, a SmartSlot for an optional network management card, and a SmartConnect Ethernet port for APC's cloud monitoring. Physical planning matters more than with a tower. APC lists 18.8 inches of depth and 58.4 lb, includes rack mounting support rails, and does not list it as two-post mountable, so plan on a four-post rack and mount it at the bottom. Battery replacement uses APC's APCRBC133 cartridge. For more rack options, including a 1500W CyberPower unit and short-depth models, see our [best rack-mount UPS](https://homelabpicks.com/ups-power/best-rack-mount-ups/) guide. ## Long-Runtime Option: EcoFlow DELTA 2 The [EcoFlow DELTA 2](https://homelabpicks.com/go/ecoflow-delta-2) is a portable power station, not a traditional UPS. Its LiFePO4 battery stores 1,024Wh and is rated for 3,000+ cycles, and EcoFlow lists 1,800W of continuous AC output (up to 2,200W with X-Boost). One extra battery takes it to about 3kWh. The runtime math is simple: 1,024Wh divided by a 100W load is about 10 hours before losses, or about 8 hours if you assume 80% overall efficiency. No lead-acid tower in this guide comes close. Two limits keep it from being the default: - **Switchover.** EcoFlow describes an EPS mode that switches to battery when the grid fails, but it is not a zero-transfer online UPS. Some power supplies may drop during the switch, so test your exact hardware. - **Monitoring.** It has no documented USB HID UPS interface, so NUT and NAS UPS settings will not see it the way they see the towers above. Plan shutdown automation separately and test it. The 3,000-cycle rating is a laboratory figure, not a calendar-life promise; temperature, storage state, and usage all affect how long the battery lasts. The DELTA 2 makes sense when your outages outlast what a tower UPS can cover and you have confirmed that your hardware rides through the switchover. ## UPS Basics for Home Labs ### Sine Wave vs. Stepped (Simulated) Output Active power factor correction (active PFC) is standard in desktop and server power supplies. Some active-PFC supplies misbehave on a stepped approximation of a sine wave: they may shut down at the moment of transfer, run hot, or buzz. A sine-wave UPS avoids that failure mode. Devices on external power bricks, such as routers, modems, and many mini PCs, are usually more tolerant. All four conventional UPS picks here output a sine wave on battery. For any other model, check the exact waveform, transfer time, and the protected device's requirements instead of inferring waveform from price. ### Line-Interactive vs. Online Double-Conversion The four conventional UPS picks here are line-interactive: - In normal operation, power flows from the wall through automatic voltage regulation (AVR). - AVR corrects many sags and surges without using the battery. - On an outage, the UPS switches to battery in a few milliseconds. CyberPower lists 4 ms typical for the CP1500PFCLCD, and APC lists 8 ms typical for the BR1500MS2. The DELTA 2 is different: it is a power station with an EPS mode. Online double-conversion UPS units avoid a transfer event entirely because the load always runs from the inverter, at the cost of price, heat, and conversion loss. Choose the topology from the protected equipment's transfer tolerance, not from habit. ### USB Monitoring and Shutdown Automated shutdown is what separates a UPS from a surge protector with a battery. NUT (Network UPS Tools) can: - Monitor battery level, load, and estimated runtime - Shut down the host when the UPS reports low battery - Share UPS status with other machines on the network so they shut down too NUT supports many CyberPower and APC USB models through the usbhid-ups driver. Proxmox, TrueNAS, Synology, and QNAP all offer UPS integration, but support varies by model and software version, so check NUT's hardware list and your platform's documentation. Time your full shutdown sequence and set the trigger point so every system finishes with margin. ### Sizing: How Much UPS Do You Need? Measure the protected load with a plug-in power meter, note the peak, and choose a UPS whose watt rating is at least 1.5 times that peak. Rough planning ranges: | Setup | Typical Draw | Suggested UPS | |-------|-------------|-----------------| | Single NAS (4-bay, spinning drives) | 40-60W | CP850PFCLCD (510W) | | NAS + mini PC + switch | 80-150W | CP1500PFCLCD (1000W) | | NAS + tower server + switch | 200-400W | CP1500PFCLCD or SMT1500RM2UC (1000W each) | | Full rack (several servers and networking) | 400-800W | A 1500W-class rack unit, or split the load across two UPS units | Then check the manufacturer's runtime chart at your typical load. See the [UPS sizing guide](https://homelabpicks.com/ups-power/how-to-size-ups/) for the full calculation. ## How to Choose **Your lab draws under 150W and sits on a desk or shelf:** Get the [CyberPower CP1500PFCLCD](https://homelabpicks.com/go/cyberpower-cp1500) if the lab may grow. If you are sure it will stay small, the [CP850PFCLCD](https://homelabpicks.com/go/cyberpower-cp850) is the thriftier choice. **You prefer APC:** Compare the [APC BR1500MS2](https://homelabpicks.com/go/apc-br1500) and confirm that your platform detects it over USB. **Your gear is in a four-post rack:** A tower on a properly rated shelf costs less. The [APC SMT1500RM2UC](https://homelabpicks.com/go/apc-smt1500rm2u) provides rails and a network-card slot. See the [rack UPS shelf guide](https://homelabpicks.com/racks/best-rack-mount-ups-shelf/) and the [rack-mount UPS roundup](https://homelabpicks.com/ups-power/best-rack-mount-ups/) before buying a rack UPS. **You need hours of runtime:** Consider the [EcoFlow DELTA 2](https://homelabpicks.com/go/ecoflow-delta-2), after you test the switchover with your hardware and plan shutdown automation separately. **Placement:** CyberPower and APC rate these units to operate between 32 and 104°F (0 and 40°C). Keep any UPS out of attics and unconditioned spaces that run hotter than that. Whatever you choose, test a real power-loss and shutdown sequence after installation and after any hardware, battery, or software change. ## Bottom Line The **[CyberPower CP1500PFCLCD](https://homelabpicks.com/go/cyberpower-cp1500)** is our primary pick when a tower format fits: sine-wave output, a 1000W rating, published runtime data, and USB shutdown signaling that NUT supports. If you standardize on APC, the **[APC BR1500MS2](https://homelabpicks.com/go/apc-br1500)** is the sine-wave alternative. For small, fixed loads, the **[CyberPower CP850PFCLCD](https://homelabpicks.com/go/cyberpower-cp850)** costs less. For a four-post rack, the **[APC SMT1500RM2UC](https://homelabpicks.com/go/apc-smt1500rm2u)** adds rails and a network-card slot. For long outages, the **[EcoFlow DELTA 2](https://homelabpicks.com/go/ecoflow-delta-2)** trades standard UPS signaling for hours of runtime. Pair your UPS with working monitoring (NUT or your platform's built-in UPS client) and test it. For the gear you are protecting, see our guides to the [best network switch for a home lab](https://homelabpicks.com/networking/best-network-switch-home-lab/) and the [best NAS for a home lab](https://homelabpicks.com/nas/best-nas-home-lab/). ## FAQ ### What size UPS do I need for a home lab? Measure the complete protected load with a plug-in power meter and note the peak. Pick a UPS whose watt rating is at least 1.5 times that peak, then check the maker's runtime chart at your typical load. A NAS, a mini PC, and a switch often draw roughly 80 to 150W, which a 1000W unit covers with plenty of margin. Our UPS sizing guide walks through the math. ### Does my home lab UPS need sine-wave output? If a protected device has an internal power supply with active PFC, as most desktop PCs, servers, and larger NAS units do, choose a sine-wave UPS. Stepped (simulated) output can make some active-PFC supplies shut down at the moment of transfer. Devices on external power bricks are usually more tolerant. All four conventional UPS picks here output a sine wave on battery. ### How do I set up automatic shutdown with a UPS? Connect the UPS to one always-on machine by USB. On Proxmox or another Linux host, install NUT with the usbhid-ups driver and let upsmon shut the host down when the UPS reports low battery; other machines can monitor that NUT server over the network. Synology and QNAP have built-in UPS settings. Time your real shutdown sequence, set the trigger with margin, and test by unplugging the UPS. ### How often should I replace UPS batteries? Sealed lead-acid UPS batteries typically last about 3 to 5 years, and heat shortens that. APC lists a 3 to 5 year design life for the BR1500MS2 and 4 to 6 years for the SMT1500RM2UC. Replace them when a self-test fails or on that schedule; all four conventional picks have user-replaceable batteries. The EcoFlow DELTA 2's LiFePO4 battery is rated for 3,000+ cycles, which is not a calendar-life promise. ### Should I get a rack-mount or tower UPS for my home lab? A tower UPS on the floor or a properly rated shelf is the cheaper path and works for most labs. Choose a rack UPS such as the APC SMT1500RM2UC when you want rails, a network-card slot, and cleaner cabling in a four-post rack with enough depth. Rack UPS units in this class are heavy (the SMT1500RM2UC is 58.4 lb), so mount them at the bottom of the rack. ## Sources - [CyberPower CP1500PFCLCD datasheet](https://dl4jz3rbrsfum.cloudfront.net/documents/CyberPower_DS_CP1500PFCLCD.pdf) (accessed 2026-09-29) - [CyberPower CP850PFCLCD datasheet](https://dl4jz3rbrsfum.cloudfront.net/documents/CyberPower_DS_CP850PFCLCD.pdf) (accessed 2026-09-29) - [APC BR1500MS2 product data sheet](https://www.se.com/us/en/product/download-pdf/BR1500MS2?filename=APC_APC-BackUPS-Pro_BR1500MS2.pdf) (accessed 2026-09-29) - [APC SMT1500RM2UC product data sheet](https://download.se.com/files?p_enDocType=Product+Data+Sheet&p_File_Name=SMT1500RM2UC_DATASHEET_US_en-US.pdf&p_Doc_Ref=SMT1500RM2UC_DATASHEET) (accessed 2026-09-29) - [APC SMT1500RM2UC product page (replacement battery)](https://www.se.com/us/en/product/SMT1500RM2UC/) (accessed 2026-09-29) - [EcoFlow DELTA 2 product page](https://www.ecoflow.com/us/delta-2-portable-power-station) (accessed 2026-09-30) - [Network UPS Tools hardware compatibility list](https://networkupstools.org/stable-hcl.html) (accessed 2026-09-30)
