Fine power suply with one very big problem
Pros: Regarded as a high quality power supply, and I see no reason to disagree.
Cons: It appears that the PFC feature of this power supply is broken. It appears this power supply is incompatible with UPS/battery backup.
Overall Review: I'm not super picky about a power supply so long as it supplies clean, reliable power. This power supply will not work with battery backup. I have tested with several different UPS units including an APC smart-ups 1500, and a cyberpower cp1500pfclcd which I purchased specifically to support this power supply's PFC feature. I also tried a couple of other random UPS's. In all cases, if the ups switches to battery, the PC loses power. Even if the AVR circuit kicks in, the PC loses power. This is not acceptable. I recommend avoiding this series of power supplies altogether unless/until this bug is resolved.
