Sorry for the blurry pic my camera was not available so i took it with my webcam lol.

OK what i need to know is should i install this over my 450watt factory installed PSU, i bought this off eBay ( >_> dont be hatin) and i knew it was fishy when i only had to pay $20cad for the total (price+S&H) i bought this when i was in my phase of BIGGER the number the better it is (the days where i was like intel 2.5ghz BEATS amd 2.1ghz, lol) so i bought this thinking i would be able install more components if i had 600watts instead of 200watt (the 450w is in my soon-to-arrive, computer. The 200w is the computer im typing on right now, this one is the family computer and the one i just bought is going to be MINE :P). I plan on installing this in MY computer because the PSU wont fit in my family computer...actually its because to install it i would need to unscrew the mobo and then slip it in, but i dont want to take the chance at unscrweing th mobo because im a noob and if i kill the computer again (yes, again) i will have to buy another...and that will cause TOO MANY problems.

If you want me to physicially type in the number and all the "blah,blah" on the PSU just ask :P

thanks in advance.
