folding on 9800gt's

post #1 of 5
Thread Starter 
I'm folding on 2 9800gt's in a p4 2.8ghz rig currently. The PSU is a 380w Sparkle psu (silver box).

The psu fan is spinning pretty hardcore lol...Is this thing gonna die on me lol?

What size psu should I be using?

Post what are the +12V rating of that PSU as that's what really matters for your rig; 380W isn't saying much, since that adds up all power available on +12V +5V and +3.3V rails, while the 9800GT & the P4 use only +12V. It might be that you oly have (say) 15Amps on the +12V which is 15x12=180W, 180W usable watts. 2 cards and a P4 at full speed consume more than that, so the PSU might be strained.

My take: post the +12V amp rating to see what your PSU can really do; also post a Speedfan screenshot while the rig is folding - this is a temp and voltage monitoring soft that should point out if the PSU is overloaded.

Your stressing that poor box out Even if it was a high quality PSU, P4's aren't exactly the most efficient processors, and 9800GT's are roughly a ~100w card each.

Just curious, how how is the exhaust being blown out?

Well the cpu is at idle (or nearly). I'll get the +12v info in a few hours, I have to dissemble it to get to the psu.

Speedfan didn't show any voltages... might be because its a dell? (psu isn't original)

2 9800gt's is going to kill that poor little thing.

Maybe pick up the Corsair CX 430 builder's psu? It is on sale AR at the egg for $25.
