This should be normal knowledge. Don't cheap on the PSU. Don't swap cables, do not treat your main source of power like shit. Literally, EVER. The price tag at Frys/Microcenter/Best Buy is enticing, I get it. Don't. It's amazing the amount of people I have come across who try to squeeze a buck on the PSU always are full of regret at the end of the day. As the old saying goes. "If you purchase a Diablotek PSU, you troubleshot your computer and decided it was a PSU before buying the product" Always test the PSU first. Always. I cannot stress this enough. Buying your PSU and immediately throwing it on also new products, thats a negative ghostrider. I feel for OP. However, everyone has done it once.
