Right, I have an I5 2500k, Gigabyte Z68X-UD4-B3 Motherboard, Western Digital Caviar Black 1TB, 8Gb XMS3 Ram And Two 6850's, I Need help on finding the right power supply that will be able to run all of the above and not cost more than £50-60. I'm Not worried if its Modular or sleeved Cables. I Tried looking for myself but i Dont have a clue on what im looking for :)

Thanks!

are you talking a new psu or a used one...because you may struggle to get something new to run those cards in crossfire....i would have thought a 700/750watt at least for safety...not many of those around for 60 quid

Id Prefer it to be a new one, I have a friend running a 6870 and a 6850 of a 450w psu, not sure on how that's possible

A couple of options below, but I think you will need to use Molex to PCI -E adapters for power.

Looking at the review below you should be pulling around 350w when gaming. (review uses a higher power i7 9xx system SB I5 uses less power)

There are plenty of PSU calculators online where you can select your components and it will estimate roughly what wattage you will need. Agreeing with the other comments quality PSU is a must. I'd be inclined to get one with some overhead on the wattage so you aren't taxing it as it'll generally be more energy efficient and you'll have margin for any potential upgrades. I saw an OCZ ZT 750w recently for 52 quid brand new - kicking myself now for not getting it!
