PSU for my SLI rig..

[vinayb]

hi, my rig would be
AMD 64 3800+
CORSAIR 2x512 3200XL
CREATIVE AUDIGY 2 ZS PLATINUM PRO
2x ASUS 6800GT PCIE
2x HDD
2x CD/DVD ROMS

Is Antec NeoPower 480 enough? I maybe adding more ram in the future, thats about it...
Any suggestions??

i think the neopower is enough, but just enough. i had one and just was not liking were the rails were ( especially the 12v @ 11.7, not that that is low) and i only have one card. plus the dual rail psu's are pretty disbuted as to whether they can be combined or not and so on. personally i would go with something with at least 24amps on the 12v rail, dual gt's are gonna suck a good amount of power. look at the ocz modstream 520 if you like the modular style, or you can go for the powerstream with the adjustable rails which i have and like very much. it is up to you, i dont think the neopower is bad at all and could prob handle it, but to be safe, i would go with more power and maybe not a dual rail (unless you go PC power & cooling sli 510)

The Antec NeoPower 480W provides plenty of amps on the 12V rails, and is more than ample for your rig, even with future expansions.

Yeah just over a month after building my new PC, my PSU is giving me problems. I would say get something that is 500+w minimum and get an ATX2.0 if you're going to use the 6800 or x800 series video cards.

antec TPII 550 is kick ass for the $. i wouldn't get anything less than 500 for sli as suggested.

i'm only running one card now but the rails are unbelievably solid on a multi. i have it running a 3200+ @2450, 6800 gt, 1 gig, 3 hdd, 2 opticals, 6 fans and 2 pci cards and the 12 (dual @ 36 combined) never drops below 11.97.

someone at dfi street told me the reason is the tpII and other high quality psu's have "feedback" lines on each rail to/from the 24 pin connector so that the psu reads what it is actaully delivering and adjusts itself accordingly. i dunno how accurate that is but i can't argue with the results.

Yeah, it should be enough. It has a total of 36A at 12V doesn't it? A setup like yours would probably manage to run on 25A, but 36A provides you with a decent capacity to upgrade.

It's enough.
