Earlier today, my PC which I've had for a little over two years now suddenly powered down. I did all the simple troubleshooting like checking the psu switch and such and it all seemed fine. Nothing in the computer was hot at all. I pressed the power button and nothing happened. Absolutely nothing. I've tried all the advice I've been able to find on the internet and nothing seems to produce any results. I don't think it is the PSU because the motherboard has a small green power light that is on, so there is at least some power coming through.
My specs are:
Motherboard: MSI X58 Pro-E
PSU: Xion RealPower 700 Watt
CPU: Intel i7-950
GPU: nVidia GTX 460 Palit Edition
6 GBs of RAM
I'm fairly certain that it is a result of something failing in the motherboard but I'd like any help you guys might be able to offer.
I think its your PSU, normally the motherboard would send a signal to the PSU to send power to all the components, I remember this method where you get a paperclip and put it into two connectors on the mother connector and it would start the PSU up. You could try this method or grab another PSU to test.
As Ruzza described, you need to get a paperclip and grab the main motherboard connector, and short green and a black wire together and make sure the bridged connection stays put, or the PSU powers off again.
I wouldnt try the paperclip method, as it only confirms the PSU works on idle, not load.
Just try it out with another PSU, and dont buy a crappy one next time.
This is probably going to sound extremely stupid because I'm not very educated in the physical aspect of computers but am I going to need to try it with a psu with similar wattage compared to the one currently installed? Or will any old one do for the sake of testing?

Also, if it is the psu, which brands aren't "crappy" in your opinion
Do I really need 750 watts if I'm not running 2 gpus in SLI? Could I drop down to like 600?
Your old one may do if the connections are the same, but it may not be powerful enough
and most PSU brands are ok just don't cheap out
The 460 is kinde power hungry, but 500 Watts should be enough.
Corsair, seasonic psu's should do.

Uh, no. There are plenty of shit brands:
Antec (prior to 2005)
Allied
Deer
CoolMax
Logisys
Xigmatek
H.E.C Compucase
Diablotek
Just PC
Athena Power
Raidmax
Startech
And probably 500 other subsidiaries that use cheap trash Chinese designs.
Tested it with another and my computer booted up so I ordered a new Seasonic psu. Thanks guys.
The only brands I'd trust for a decent build are the big ones; Corsair, Thermaltake, Cooler Master, etc
I was always told that when you're dealing with the device that has the power to run your shit nicely or fry all your hardware you should go for quality
