What a great post.
Thanks very much for that information Mr Krugga, I have that exact Corsair PSU and I really don't want to spend a fortune getting another one! OcUK don't seem to stock the modular Corsair's anymore
Thank you. There's quite a lot of misleading information regarding power supply units and I thought that pointing out some common misconceptions would be helpful for some in this thread.
OcUK does stock modular Corsair PSUs, they do seem a little overpriced though (HX range starts with 650W at over £100...).
Look at HX and AX over here if you're interested - http://www.overclockers.co.uk/productlist.php?groupid=701&catid=123&subid=1084&sortby=priceAsc.
I hate to say it but most of these PSUs can be had for £10-20 less from competitors.
