SuicideMayne · 09-13-2005, 06:36 AM

i think i have a problem with my psu im using right now....

when i am playing a game that needs alot of power like farcry i get a message that pops up saying "graphic cards are not getting suffient power"

and then it lowers the clocks so it can go on....

i dont think my psu is really ment for SLI it has 22A on the 12v 8-( i dont think thats enough for 2 6800GTS

someone please help it seems like the only way to pass this is if i beem a big ass fan in the case why that helps i dont know maybe u can tell me..

You seem to be perfectly right about that AMP figure not being enough for an SLI setup. In this case, I would refer to Praetor's PSU101 and aim for some of the best PSUs. You are looking at two hungry beasts that need a powerplant to run

well.. they just released the first KiloWatt PSU

no, get one with at leadt 24 Amps on the +12v. ( recommend 28Amp's tough

)

28A recommended, 32 would be "tough".

24 amps is enough for a fully loaded system with 2 6800ULTRA's, 2 pci cards. and all usb ports full, a x2 4800+. (im shure about this, because the book that came with my mobo tells so.)

Hehe don't you bet on that.

I'm running the stuff in my sig on a 24A psu atm & I wouldn't want anything less.

24 is "enough" if you don't do anything strenuous with it (such as playing farcry, D3, BF2, whatever at highest settings). When you pump it up you also pump up the amount of power needed by everything.

forgot to mention.. that was under full stress. though that would be clear.

and maybe i should mention that my pc before i got it, was tested 40 hours under full load (with 2 6800ULTRA's ) with a 24A +12V PSU, before delivered.
and,. apearantly, it managed the test.
