Do I need more power?

[egale]

I am currently running with a seasonic 500w power supply. Using the psu calculator at ASUS and Newegg, they tell me I need about 650w. I have been having some BSOD problems and I replaced my memory which helped for a bit but now they are back.

I have a quad 6600 @ 3ghz, 4gig, 8800gt, 2 hard drives, 2 optical drives, 3 120mm fans. It seems to me when I built this system, the calculators were saying less but now I am under powered.

Looking a 750w psus now. Thats got to be enough????

Make sure your RAM is at the right voltage, does the crashing occur at stock speeds?

Seasonic 500 is a good PSU however but which model? (Does it have the 8pin connector for CPU?)

Corsair 550VX should work well

That 500W PSU should be plenty. The PSU would not be first on my list to troubleshoot.

You have an overclocked processor, and replacing the RAM appeared to influence the problem, so there are two obvious suspects. As BassBomb said, it would be helpful to know the exact specs of your RAM (and motherboard). What are the temperatures like on your chip?

Motherboard is ASUS P5KE/Wifi, current bios. Old memory was Crucial Ballistix 1gb x 4 running at stock speed DDR 800, 4-4-4-12 2T 2.2v. New memory is Corsair 2gb x 2 running at stock speed DDR 800 5-5-5-18 1.9v.

Nothing else is OC'd except CPU @ 3ghz. CPU idles between 35 - 37 degrees.

The BSODs are now few and far between. The last one was at wake up. Everything seemed to come back except the video. I did a reset, the system rebooted, windows came up and a few seconds later BSOD'd. The second reset went fine. The machine is 100% stable except at startup/wakeup/shutdown/sleep.
