PSU for i7 system

[BlueMagician]

Hi,


I've just ordered a bunch of components from Scan, to build a new i7 sysytem based around the 920 CPU, Intel mobo, and an XFX GTX280 GPU.

I've not paid any attention to a Power Supply for this new kiddy.. :/

Will my existing OCZ Powerstream600 brick be okay? Have they changed the spec or requirements for i7 whilst I wasn't looking? Random extra connectors needed that my PSU doesn't have, or outrageous power requirements?


If not, what should I be looking at, and adding to the order very quickly? lol.


Thanks in advance,
S.

Should be fine. If the 280 needs extra connectors it should come with adaptors to use with spare molex.

I've just re-visited the specs of my current PSU, and I'm a little worried that it's only got two 12v rails, max draw 20A and 18A. Are ye sure this'll be enough for the XFX280 ?

And, what if my inner demons smack me around the face and force me to buy a second 280 for SLI goodness.. Surely I'll have to rethink PSU at that stage?


Thanks all in advance,
S.
