It randomly shuts off. No BSOD no reboot. just dead. and then when i try to power it back on, it turns on for 5 seconds then turns itself off again. So what i have to do is take out the power cable and take it out the socket and plug it back in. then it turns on.

Start by swapping in a known good pw supply. Note known good does NOT mean new; it means a pw supply pulled from a working system that you know works.

Next it would help if you posted your exact system specs; "Asus motherboard" does not really tell me very much. What you need to post is as follows;
Exact mb along with version number if used AND bios version you are currently running
Exact ram installed
Exact pw supply, etc, etc.

Um, it seemed to stop? No idea why...

It sounds like a power supply rail is "dropping out" most likely from overheating. With a quad core processor and a 9800 series card you should have a quality brand power supply. minimum about 650 watts with 50-55 amps on the +12v rail.

Why does a rope break? Things wear out AND when you stress any part at or near it's max rating ie your pw supply, it wears out faster.
With an under powered pw supply, you are doing the same thing as driving your car at full throttle all of the time. How long do you think the engine in your car would last if you did that???

OCZ is an OK power supply, what I don't like about the unit you picked is these three items.

http://www.newegg.com/Product/Product.aspx?Item=N82E16817341048

#1-The max rated output on the +12v rail is 46 Amps.

#2-The output power is rated at 40°C.

#3-3 Year warranty

This one; http://www.newegg.com/Product/Product.aspx?Item=N82E16817139020

#1-Max rated output on the +12v rail 53 Amps.

#2-The output power is rated at 50°C.

#3-5 Year warranty

Additional specs;

If you can afford the Corsair unit, I personally would go with Corsair.
