kidstar64 Posted November 27, 2008 Share Posted November 27, 2008 ok so im shopping for a UPS however im confused about the whole volt/amp thingy. I have a 750 watt psu but oonly using about 550. I dont need this UPS to boot from a cold start however when the power goes out, i want it to shut down my computer. would a 750 volt amp be sufficent? I have talked to some people about it and they said that it should be fine but im still not 100 percent. Thanks in advance Quote Link to comment Share on other sites More sharing options...
Sparda Posted November 27, 2008 Share Posted November 27, 2008 Where did you get the magical 550W from? Quote Link to comment Share on other sites More sharing options...

Sparda Posted November 27, 2008 Share Posted November 27, 2008 Two things: That number is probably wrong (I'd say 90% chance). That number (if it is accurate) is how much internal power the PSU is supply and is not the same (and is probably very different) to how much power the PSU is drawing from the mains. Get a power meter and measure it. Quote Link to comment Share on other sites More sharing options...
