Seems like a reasonable value however I wouldn't trust the Chinese PSU.

Your 450W is enough for your Radeon HD 5570 -- you should have no problem with it, however PSUs failures may damage other components, so be warned!

For your reference have a read at "Don't Be Surprised When Your Cheap PSU Blows Up " http://www.tomshardware.com/reviews/low-cost-psu-pc-pow...

Yes I know lot about blowing up PSUs :p  because my last gigabyte 550W PSU just blown up when a damn cockroach went inside it :(  so since then I have to stick with these chinese ones btw.
Thanks for the replies and I'm gonna upgrade my PSU as soon as I find a job :)
