Ace 750w PSU

[projectlll]

Hi guys, im going to upgrade my home-built system by adding a Nvidia GTX 570, but currently i have a 500w psu, and using the thermaltake power supply calculator it told me that i would require 590w, 90w more than my current configuration, since i want to maximize the money spent on my gpu i want to minimize my psu cost, so i found this 750w ACE Psu for £20, so my question is, will it work, and will it output the rating its been given? (750w) (A link to the product is supplied below)

Don't cheap out on your PSU. Get at least Bronse 80 rating. I went cheap and it ended up costing me a new MOBO when it fried.
