Do i need a more powerful PSU?

post #1 of 5
Thread Starter 
I have a 580w atm, virtually overclocking all of my components. I have 3 hard drives, 7 fans, a DVD drive on top of everything in my sig. My PSU gets very hot sometimes when gaming, and I don't think my 8800GTX is performing as well as it should be. I'm just wondering whether I need a more powerful PSU?

My current PSU has 30A on the 12v dual rail combined if that helps.

Most likely yes. The 580W Hiper is weak on the 12V rails (only 30A combined). That's not enough for your rig.

This Corsair should be just fine:

52A on a single 12V rail... now we're talking And very high quality!

(heck, even the 550W VX version delivers 41A on a single 12V rail, and would do just fine... proof that Wattage isn't all to look at).

A quick run of that calculator gives me 712W... which is pretty much a lot more than he needs (input: core 2 quad series; High-end Desktop motherboard; 8800GTX x1; 1GB DDR2 x4; DVD-RW; 7200RMP HDD x3).

Again, a GOOD quality PSU that delivers ~40A or more will be just fine. The 650W Corsair delivers that and then some... with plenty headroom for some good overclocking.
