I'm looking to buy this PSU: http://www.pcworld.co.uk/gbuk/corexstream-ocz-csx500w-uk-atx-psu-500-w-15050623-pdt.html It has a 20+4 ATX pin but my mobo has a 24 pin connector. I need it mainly for my 8800GT which needs a 6 pin PCI-E and that PSU has one. Will I have to look for another PSU/buy an adapter or can it work?
