A:Answer I can't speak for all of them since the RAM cards in the SLC10000CPGV3 model from CyberPowerPC vary between different units, but I just replaced my brother's PSU after a mere 16 months of life before it completely ceased to function and his was:
Manufacturer: ATNG POWER CO., LTD
Model: AP-800X-G
It's 800 watts, it isn't modular, and the labeling on the unit itself doesn't specify an efficiency rating, although one seller on eBay has an identical PSU listed as:
ATNG AP-800X-G Power Supply 80+ Gold CyberpowerPC
I'm not sure the 80+ Gold rating is legit though, and the manufacturer's warranty for this PSU is only 1 year, so make of that what you will. I would suggest an immediate upgrade to a modular PSU from a more reliable manufacturer with a longer warranty immediately after purchasing this PC.
