Lower Watt PSU cause PC to slow down? Tags: CPUs Windows 7 Last response: April 9, 2010 4:35 AM in CPUs Share integraoligist April 9, 2010 1:45:26 AM My PSU took a crap the other day (which was 450W) so I replaced it with a 350W PSU i've had lying around. And now i swear that the pc is running slower. I'm running Windows 7 Ultimate 32bit with 4g ram and a Core2 6400 @2.13ghz Is this even possible or am i imagining this?
