would seem my kids machine with a 500w psu (30a on 12v rail) isn't actually much good and wont run an HD 5830.... so need something that can and not expensive please is http://www.overclockers.co.uk/showproduct.php?prodid=CA-063-OC&groupid=701&catid=123&subcat=2463 any good?
Seems odd I have far worse on less What brand psu? And that OCZ is a bit meh stump up a extra 5er and pick up a corsair or something.
OCZ are about to go tits up it seems. http://www.ebay.co.uk/itm/100-B1-05...raphics_Video_TV_Cards_TW&hash=item4acac2cfdf IMO
Something like this should do the trick. http://www.scan.co.uk/products/600w...le-rail-sli-crossfire-120mm-quiet-fan-atx-psu A £35 PSU is not going to be a good PSU if you ask me.
