Ok, Here's my situation: Ive got a top of the line 680 Sli motherboard, 600 watt power supply (also by Xion) and a Xion Onyx case. Unfortunately, i'm finding that parts of the front panel arent working!
Both power on buttons aren't working, and I know its not the motherboard, as the manual power on switch on the board turns it on. The reset button works fine, as do the USB ports, but the mic port and the headphone jack don't work eather. How do I fix this? The front panel seems very well secured..so if its a connection there, I have no idea how to get to it.

My two cents worth;
I would suggest you actually test the power button with a multi-meter or some other continuity checker. If it truly is bad then if your case is still under warranty you should call before doing any thing else. If you start taking things apart you will wind up voiding the warranty which could get ugly later.
With that many things not functioning on the front panel it would seem likely that the front panel board, connector or something else they all have in common is defective.

I believe your right, think your going to need a new power supply. 430 watts is a little low, but should be able to run this board smoothly even with dual video cards. If you do decide on purchasing a new power supply I would go with a 600 watt 20+4 pin, you might think its over kill but power supplies running at peak output over a long period of time shorten their lifespan. Plus its always good to have room to expand.
depends on what else you have got plugged in, I would get a minimun of a 400 watt from a good manufacturer, so you will have a good supply of power over the main rails, most cheap 400 watt supply's cant sustain any where near 400 watts
have a google for power supply reviews
just get one like the one that went out. id recommend a 600 watt power supply xion.com has good one make a list or notes if you must or replace one lead at time and make a note of where it goes before you disconnect it '
the reason im recommending a 600 watt is most power supplies are marginal to begin with in my opinion. so getting a higher rated unit allows you to add accessories you might want to adds i burned up a chief max 600 watt in a month for some reason replaced it with a 425 till i got a new one and bought a 600 watt xion.com power supply the original was 425 watt. i guess i got what i paid for the chief max was only 28 dolara from 3btech.net (a good site to bookmark
The ATX power supply needs to have pin16(PS_On#) to be connected to COM for it to work.
When you press the power switch on the front panel of the computer, you are essentially making this connection.
Check that the cable from the power supply to the motherboard is making good connection.
You can verify operation of the power supply by shorting Pin16 to pin17 on the powersupply output, with a paper clip. Pin16 is usually a green wire and 17 is black.
Hope this helps.
