most PSU's these days still draw power and supply power to the mobo as long as they're plugged into the socket (hence why some optical mice still stay powered up dispite the pc being turned off.)
the only way your going to lose data on these is if you have a SERIOUS powercut that lasts about 20 hours... and lets be honest, that rarely ever happens (infact the longest i remember is about 12ish).
i'm not sure if thats aimed at me, or athe guy who made the comment about having to sell everything he owns to do with his pc to afford it.
personally, i'm only complaining about UK pricing. yes this is brand new stuff, yes its high end, high performance hardware we're dealing with. and yes, there has always been a divide betwee UK/US pricing... but when your talking about us paying over double the US price... its a little ridiculous.
an american competitor has these for $80 on release (of course not including shipping), whilst OcUK sold them for almost £180 on release.
again, this isn't really a dig at OcUK - more of the annoying price of hardware/goods in the UK compared with elsewhere.
