I have an Antec Truepower 430 watt power supply and I'm a little worried about how much power I have left for my PNY Nvidia 6800 GT.

I'm running:
Asus K8N-E Deluxe
Seagate Barracuda 200 GB IDE
4 Thermaltake Smart Case Fan 2's
1 Antec 34cfm led
4 Antec no led 34cfm fans

I've had a little bit of problems with that power supply, the little switch on the back that you need to flip for it to recieve power has broken it seems. It shouldn't let me take out the power cord when it flipped on, but it does. I think I might have undervoltaged my old 9800pro, but I'm not positive. I think it's working properly, but I'd like to check it for just that. I could look in the bios to see the voltage, but what should it be at? I'm not much of an electician.

It'll give you an idea of how much you're actually using.
You can also use a multimeter to test the output of your PSU...don't ask me how...i'm clueless, but others here are not

As much as I like to be a smarta$$, this is from the heart.

Your 12V rail should be close to (can ya guess?) 12V. 11.8-12.3 is all good in my book.

Your 5V rail should be (no cheating on this one) you guessed it! It should be pretty close to 5V. 4.75 -5.2 is damn good for me.

You only gave us half your specs, but from what I see you should be just fine with 430W.

Try the overclockulator to see how much you need under max draw.

Other than that, I don't know WTF you are talking about with your power cord.

I was thinking that if he was that concerned about an undervolt, he shouldn't rely on bios or software to get the readings, he should test with a multimeter (i don't know how to use a multimeter)

The switch has nothing to do with the ability to "physically" remove your power cord......it merely turns power on and off TO the power supply.

Short answer, might as well try it with your current PSU before you get a new one.

For the multimeter. it has 2 cords, Red and Black. Red = voltage, Black = ground.
a Molex plug has 4 wires, (2) Black = ground, Red and Yellow are 12v and 5v, not sure which is which.

Just put the ground cable from the Mutli to one of the grounds on the molex (DOES NOT MATTER WHICH ONE) then hold the red multimeter cable to the red Molex pin then the yellow one; one will be in the ballpark of 12v, the other of 5v. This reading is what your PSU is spitting out, not what any compents are really getting. To find that you need to find the voltage read points on your hardware and then be steady enough not to short anything out.
