I got this cheap case and it came with this PSU. Last night i did some case modding and added 2 120mm fans (a total of 6 fans in the case now). At random times my computer will go into "sleep mode" and you have to reset it. I did a quick calc and im at about 15amps on the 12v rail. The 12amps on this supply is the stability problem i believe. And whats up with 40amps on the 5v?

A 430 watt PSU that can only put out a Max output of 425 watts. Let me guess Case stock right? Cheap case?

A 400 wat PSU is decent. Depends on what else your running... If you've got a decent newer gaming rig, then you will need an upgrade.

I recommend a 600watt PSU.

Or trade them in for a "Water Cooling" system. It'll keep your system cooler than 6 fans will.

Also, get an Aluminum case, WAY Cooler. :cool: I'm talking about freezing.

Yep- cheap case, nice for modding though, got a bunch of more cutting to do. I bought a 465w Enermax PSU (33amps on the 12v rail) should do the trick. I know 6 fans sounds over the top, but i can run them at low speed and still keep it nice and cool. 27-30c idle-around 38c under load.

The highest amount of watts you will ever need is 500 watts. A X800XT PE only requires around 380 watts with all other appliances. Dual 6800 Ultras are the only reason for 500 watts. Why the hell do you want 600 watts; to pump up your electric bill?

Yes, you need[ed] a new PSU.

And 600W = wonderfully upgradeable. It's either that or a 6800GT for my next upgrade.

Yes he does need a new one. But I'm saying he can get a 400 watt that can preform better. Lets say that 600 watt power supply has a efficiency of 60%. That mean 60% of the 600 watts are being used when you have your computer on. Thats 360 watts. Which means your power supply will probally never go over that amount. So no matter what, you are using 360 watts.

turtile's got a valid point. I think I overestimated the power consumption, of the fans.
