I have had a CyberPower UPS on my desktop for over a decade and added more units over the years for network gear and a small homelab. CyberPower is the brand I land on whenever APC is overpriced or out of stock, and the value-per-dollar is consistently strong. Here are the five units I would actually buy in 2026.
| UPS | VA / Watts | Waveform | Best For |
|---|---|---|---|
| CyberPower CP1500PFCLCD | 1500VA / 1000W | Pure sine wave | Gaming PC and main desktop |
| CyberPower CP1500AVRLCD | 1500VA / 900W | Simulated | Home office desktop |
| CyberPower CP900AVR | 900VA / 560W | Simulated | Router + modem combo |
| CyberPower CP1350PFCLCD | 1350VA / 880W | Pure sine wave | Mid-range PC |
| CyberPower OR1500LCDRM2U | 1500VA / 1000W | Pure sine wave | Rack and homelab |
CyberPower CP1500PFCLCD
The CP1500PFCLCD is the unit on my main PC and it has saved my work through three multi-hour outages. Pure sine wave output handles active PFC power supplies without complaint, and the LCD readout shows load percentage, runtime estimate, and input voltage at a glance. 1000W is enough for a midrange gaming PC plus a single 27-inch monitor with about 10 to 12 minutes of runtime.
CyberPower CP1500AVRLCD
If your PC has an older (non-active-PFC) power supply or you just want a workhorse for a basic home office, the CP1500AVRLCD is the value pick. Simulated sine wave output, same 1500VA rating, and 50 to 70 dollars cheaper. I have one on my partner’s desk powering a desktop, two monitors, and a desk lamp. runs about 14 minutes on full load.
CyberPower CP900AVR
For network gear, the 900VA model is the right size. I have one on my modem, router, and a small switch. total load around 40W. and it runs for over an hour during outages. Keeping internet up during a power blip is genuinely useful when you are also on a phone hotspot. It is small enough to tuck behind the desk.
CyberPower CP1350PFCLCD
The CP1350PFCLCD splits the difference between the CP900 and CP1500. pure sine wave at a friendlier price point. I would buy this for a mid-range PC and a single monitor where the CP1500 would be slightly overkill. About 8 to 10 minutes of runtime at typical desktop loads.
CyberPower OR1500LCDRM2U
For my homelab rack, the OR1500LCDRM2U is the unit I run. 2U rackmount form factor, pure sine wave, network card slot for SNMP monitoring, and the same 1500VA capacity as the desktop models. I have it on a network card and pulling shutdown commands to a small NAS and a Mini PC server.
What Matters Most
Match your waveform to your hardware. Pure sine wave for modern gaming PCs with active PFC power supplies (the PSU will detect simulated sine wave as bad power and either shut down or run noisy). Simulated is fine for older PCs, network gear, and most accessories. Size by watts, not VA. actual draw matters, not the rated input.
My Setup
CP1500PFCLCD on the main desktop, CP1500AVRLCD on the secondary workstation, CP900AVR on the network closet, and the OR1500LCDRM2U on the rack. All four are connected via USB or network for graceful shutdown signaling through PowerPanel software.
Common Mistakes
Sizing by VA alone and ending up with a UPS that cannot actually power your load. A 1500VA UPS rated at 900W will not power a 1000W draw, even though the VA looks generous. Also, do not skip replacing the internal battery every 3 to 5 years. UPS units silently fail when the battery dies and you only find out during the next outage.
Final Recommendation
For a typical gaming PC or home office, the CyberPower CP1500PFCLCD is the right buy. The CP900AVR is the easy add-on for network gear. Go to the OR1500LCDRM2U only if you have a rack to mount it in. Replace your UPS battery on a calendar, not on a vibe.
Frequently asked questions
What is the difference between simulated sine wave and pure sine wave UPS?+
Simulated (stepped approximation) is cheaper and fine for most desktop PCs and routers. Pure sine wave is required for active PFC power supplies common in modern gaming PCs, audio gear, and some medical equipment. When in doubt, check your PSU spec sheet or just buy pure sine wave.
How long should I size my UPS runtime for?+
For graceful shutdown of a PC, 5 to 10 minutes is enough. For ride-through during typical brownouts, aim for 15 to 30 minutes. Longer runtimes than that get expensive fast. at that point you should be looking at a generator or a larger UPS.
