05-25-06, 07:36 AM
Hey guys im new to the forums and wanted to make a question.
My specs
Atlhon fx 55
Dfi Lan Party nf4
1 ghz Ram
BFG 7900 GTX 512

dunno if it matters but i have a case asus vento with a big fan a cd writer and a disk drive.
The question is, im powering this thing with an Antec TPII-430 power supply. Is that enough??

I'd say you're probably going to have problems, especially if you decide to start overclocking your system.

If you can spare the change, I'd recommend the model I have in my sig below. The model# is ST56ZF (make sure it's the one with the single 12v rail at 38A). Newegg has it for 137.99$

Even if you decide not to go with the Silverstone, there are some others to choose from that will fit your system nicely. OCZ Powerstream(?) 520W, PCPower&Cooling 510w, for example.

Just make sure you go with one that has a single 12v rail with high amps on it. I and many others have run into many problems with dual 12v rail power supplies.

Good luck.

The Antec 430W psu's that I have used furnished very acceptable power with a rating of 20A on the +12V. 20A is probably on the minimal side for a GTX. IIRC 24A is recommended. Still, if your system is running stable you are probably OK. However, I agree with Xion X2 on overclocking. If you decide you want to overclock the GTX you should be looking for a stronger psu.

I had a ANTEC truePower 430watt and it would not run my system right when I had a 6800 ULtra.

Do the dual 12v rail psu's only have problems when there are actually two cards installed or can they have problems with just one? I ask, because my psu has two seperate PCI-E connectors, but I am only using one right now. The other is in the box.

Not sure exactly what you are asking but I have 3 systems running using PCI-E compatible power supplies and none currently are using the second PCI-E connection from the power supply. Each use the dual +12v setup and I have not yet had any problems with one connected or both connected to PCI-E cards.
