[xFrugal1ty]

my parts
Foxconn C51XEM2AA
Opteron 1214 @ 2.20GHz would like to get it as close as possible to 3
2 x 1GB Crucial Ballistix have yet to pump extra voltage in these to overclock them. . . i may yet
3 x Seagate 80GB SATA
2 x Western Digital 160GB SATA
2 x Optical drives
2 x 7900GS in SLi (obviously)
floppy, card reader, and fan controller

i;m guess something quality 600?
right now i'm rolling with an antec earthwatts 500, with one less hard drive no card reader or fan controller and no overclocking.

Please Refer to this Thread : PC Power Consumption


The PSU that you have now is more than adequate.

Your Peak Power Consumption with that is no more than 280 watts. You should be fine !

well that is good news, but i see you sprung for the 750W silverstone, why's that?

2xBFG Tech 8800GTX

Because I have tried at least Three 680i SLI MOBO's and after numerous RMA's, and the same old NVIDIA Crapola.... Crap Drivers, Crap Core Logic for Intel .... and Crap SATA Controllers.

I went to a P35 now, and never revised my Sig.

so how much you think your system pulls from that power supply?

Based on my other Experiment 325 watts max.I'm only using One Card at this point... so that is allot of it.

Based on my Study 450-500 would do the job on this system as currently configured.

With the 680i and the NV 8800GTX SLI 700-750 watts was the magic number.
