Manufacturer description

The CyberPower EC650LCD Ecologic UPS gives your desktop, retro PC build, or network rack a 650VA/390W buffer against the brownouts and blackouts that corrupt drives and interrupt long sessions. Eight NEMA 5-15R outlets split into four battery-backup-plus-surge outlets and four surge-only outlets, so your tower and monitor ride through an outage while the printer and speakers still get clean power. The multifunction LCD panel reports battery charge and line conditions at a glance instead of forcing you to decode blinking LEDs. ECO Mode is the piece that pays you back: when the UPS senses your…

CyberPower's power protection lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions

How much equipment can the EC650LCD actually run?

It is rated 650VA/390W, so it suits a workstation, monitor, modem, and router. A gaming PC pulling more than 390W at the wall will overload it.

Is this a pure sine wave UPS?

No. The EC650LCD uses simulated sine wave output. Most desktop power supplies accept it, but confirm compatibility if your PSU uses active PFC.

How long is the warranty, and does it cover the battery?

CyberPower lists a 3-year warranty that includes the battery, plus a connected equipment guarantee.

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 the three ECO-controlled surge outlets. It requires the USB connection to the PC.

What does the LCD panel show?

The multifunction LCD displays immediate battery and power condition details, including charge state and line status, so you do not have to interpret indicator lights.
