I just built a new computer. I will list the parts below.

RAM: http://www.newegg.com/Product/Prod [...] 6820134012

Motherboard: http://www.newegg.com/Product/Prod [...] 6813188036

Processor: http://www.newegg.com/Product/Prod [...] 6819103274

HDD: http://www.newegg.com/Product/Prod [...] 6822136075

PSU: http://www.newegg.com/Product/Prod [...] 6817148027

When I first turn it on, It will stay on for about a minute. If I try again, it will power up and then turn off approx 3 seconds later.

Also I noticed that after it turns off, the NUMLOCK key on my keyboard will remain on even though the computer is now off.

Any help would be appreciated.

Most likely a heat issue. Make sure that you installed the CPU cooler correctly and that you applied the correct amount of thermal paste.

I narrowed it down to the CPU power supply. When the 4 pin is plugged in, it resets every 30 seconds or so, when it is unplugged, it runs continuously. Would this be a problem with the PSU or the motherboard?

I have had many people tell me that it is my PSU. Since my motherboard uses an 8 pin. Should I find a PSU with an 8 pin connector or would a PCIe 6+2 work just as well. What do you recommend?

The PSU that you selected is one step above junk.

If the replacement PSU does not have an 8 pin EPS connector, plug the 4 pin connector into the 4 pins closest to the CPU socket. The plug will only fit one way. DO not use a 6+2 PCIe connector there. It's wired wrong. If you managed to plug it in, you would groung the 12 volt output. Hopefully, the protection circuits in the PSU would electronically shut it down before damage occured.

Although I used a couple of those particular PSUs in low-power rigs a few years ago, I'd agree with jsc that they're really only a step above junk.
Your symptoms are consistent with an overheating problem. If you go into your BIOS to the "PC Health" (or similar) screen, what are your temps? Are they climbing?

How would I go about cooling down my system. Is it just the CPU that needs to be cooled with a CPU fan? Also can someone recommend a PSU for me to buy to power my system? I am looking to purchase the one below but will consider any other one recommended.

What case do you have, how many fans is it running, and what video card are you running?

That PC Power & Cooling 610W is way overkill for that rig. The Antec Earthwatts 380W should be more than enough for that rig, especially since you're using onboard video, and it will save on your power bill

Here's another good psu for the same price as that Antec, but it has better specs.

I think the Corsair 400cx is a perfect PSU for this build. It's a very solid PSU and has 30A on the 12v rail. It also costs less than the previous two suggestions.

As Why_Me asked, what case do you have? Depending on where it has places to mount fans, in a typical mid-tower ATX case, fans in the rear and top (if present) are exhaust, and fans in the front and/or side are intake, in order to create a balanced flow of air through the case.
I just noticed that you bought an OEM CPU, which means it did not come with a CPU cooler. What CPU fan did you put on it? If you didn't get one (it isn't on your list), you'd get exactly the symptoms you are describing. The CPU MUST have a heatsink/fan attached to it, with a thin layer of thermal compound sandwiched between them.

I bought this case.

http://www.newegg.com/Product/Prod [...] 6811129042

And no I do not have a CPU fan. Recommendations?

Also, would that 400w corsair still do with the addition of the CPU fan and the fans from my case?

By the way thanks for all of the help (:
