Ok I have an APC UPS and an aspire 680W psu in my pc. The power where i live is pretty unstable, thats why i got a ups, but I have run into a rather large problem.
The UPS i have only puts out 80 volts AC when its running off of the battery backup (I tested this with a volt meter so yes it is correct) and my psu has overvolt and undervolt protection on it. So basically when the power to my house flickers and the UPS kicks in my psu shuts down bc its not getting enugh voltage from the UPS.
So more the less my UPS is useless. What can I do to fix this problem? One solution I have thought of is, because my UPS is rated at around 300W and my psu is 680W the ups just cant cut it, so would getting a ups rated at 700W or more fix my problem? or would I still get under 120v ac from that bigger ups?
One more thing I need to say is I dont know if it is actually the undervolting of my psu that is causing it to shut down. It is the only thing that makes sense to me though. Also if this helps my psu has an active PFC, and this is a link to it on newegg for full specs Link
