Ok, so I have 2 PSUs in my house: 480W TruePowerII Antec - main rig: 1gig of ram, x2 3800+, x850xt, 1 HD 400W Fortron (FSP Group) - emachines rig: 512megs of ram, 6100 IGP, 1 HD, 3000+ sempron When I feel the air coming out of the fortron, it's cool. Literally. When I feel the air coming out of my antec, it's warm. Not "hot", but warm. Now that I feel it again, it's not "hot" at all, but it IS indeed warm. Am I to be worried? Or is this normal? I'm just worried because my fortron is all nice and cool, and this baby that's powering my rig is warm... Also: do you think it's safe to keep running with this one if I were to get a 8800GTS (320MB)? It says it needs a minimum of 400W, which my unit has, and 26A on the +12V rail, which I have as well... my systems isn't really all that loaded: AMD A64 X2 3800+ 1GB Corsair DDR2 1 HD 2 DVD-RW 4 case fans and 2 LEDs ... pretty much it. Thoughts?
