Hello, i am putting a pc togeather, and i got all my parts hooked up. Then when i went to start the PC my power lights/fans come on and i heard my hard drive come on with my CD ROM working. Then like after 30 seconds of the computer being on it would totally loose power and go off. It is set on 115v. Then i tryed setting it on 230v, and the computer would stay on then but my hard drive wouldn't work with 230v, and the power light would just blink. Then i got to reading and seen 115V is what i need it on for united states. so i was just wondering if it sounds like my power supply is bad? It is a 450 XION power supply new.

Possible, but I would check your cpu fan/heat sink/thermal grease too. Too much thermal grease will trap the heat in and overheat the cpu, as will a fan that is not right for the cpu or not functioning well. When the cpu overheats the computer turns off.

One of the answerers above claimed a PC in use is like having on a 40watt bulb. Well, if your 40watt bulb draws about 150-200watts, I'd seriously ask for my money back. I've checked a number of the PCs I've owned with a power-consumption meter, and they tend to use between 150-200watts. Power is measured in watt/hours, so a PC like this left on for an hour would use 200watt/hours of electricity. These PCs have had processors in the 1.5Ghz-2GHz range. If you're using a really fast processor and you do a lot of gaming with a fancy graphics card fitted, you could probably stick another 100-150watts onto that. A CRT monitor uses a fair amount of power too - my old 15inch one averages about 80watts. LCD monitors tend to be less power hungry than CRTs. Leaving PCs on when they're not in use is not only a waste of money but obviously also an uneccessary contribution to global warming. Another point to bear in mind is that electronic components have limited lifespans, usually measured in tens or hundreds of thousands of hours. Capacitors (you'll find plenty of these in your power supply and on your motherboard) have shorter lifespans than many other components, drastically shorter if they're run in warm or hot environments.

Xions are pieces of crap anyway, and they are always creative to be able to report 450W. Also, you killed it by setting it to 230, so even if it was one of the few that work, it doesn't now. Try to go for OCZ's GameXStream (not Modstream, etc.) series or for FSP Group's PSUs. They always report power correctly. Also look for a good amount of amps on the 12V rail.

You didn't kill it by setting it to 230v, don't worry.
Try removing the BIOS battery and putting it back in after a couple of minutes.
