Pros & Cons

Pros

  • ✓ ECO Mode auto-kills peripheral power when the PC sleeps, cutting idle draw
  • ✓ 3-year warranty includes the battery itself, not just the electronics
  • ✓ Eight NEMA 5-15R outlets: four battery-backed, four surge-only
  • ✓ Right-angle 45-degree plug and 5-foot cord sit flush behind a desk

Cons

  • ✗ Simulated sine wave, not pure sine - some active PFC PSUs reject it
  • ✗ 260W usable output limits it to one PC plus a monitor, not a gaming rig
  • ✗ Standby topology switches on outage instead of always conditioning power
  • ✗ ECO Mode needs a USB connection and PowerPanel software to function

Manufacturer description

The CyberPower EC450G Ecologic is a compact standby UPS built to keep a desktop, retro PC bench, or networking rack alive through brownouts and short outages. It delivers 450VA/260W of battery backup using simulated sine wave output, enough headroom for a workstation plus a monitor or a router-and-switch pair while you save your work and shut down cleanly. Eight NEMA 5-15R outlets split the load: four give you battery backup plus surge protection, and four are surge-only, three of which are ECO controlled. That ECO Mode is the EC450G's signature trick. Once the bundled PowerPanel Personal…

Frequently Asked Questions

How much can the CyberPower EC450G actually power?

It is rated 450VA/260W. That covers a desktop or workstation plus a monitor, or a router, modem, and switch. It is not sized for a high-draw gaming PC with a discrete GPU under load.

How many outlets have battery backup?

Four of the eight NEMA 5-15R outlets provide battery backup plus surge protection. The other four are surge protected only, and three of those are ECO controlled.

What does ECO Mode do, and do I need software for it?

When the UPS detects your computer is off or asleep, it cuts power to peripherals on the ECO outlets to reduce idle energy use. It requires a USB connection to the PC and the free PowerPanel Personal software download.

Does it output a pure sine wave?

No. The EC450G uses simulated sine wave output. Most standard power supplies handle this fine, but if your PC uses an active PFC supply that is strict about waveform, verify compatibility with your PSU manufacturer first.

What warranty comes with it?

CyberPower lists a 3-year warranty that includes the battery, along with a Connected Equipment Guarantee. Check the product listing for current terms, coverage limits, and claim requirements.
