Thinking of a 750w PSU

See sig for spec, but will be switching to I7 in a few months and adding in second GTX280 bought in the OCUK sale.... Will that do the job.... Or should I go higher?
 
how also i would suggest that since you will be at the top of the 750w, you should go a little higher. Put simply the PSU has an efficient operating range, and if you are at 90% loading on a 750W PSU, you will not be as energy efficient as if you were at 70% of a 1000W PSU.
 
Right well just made a trip to a competitor - normally always shop at ocuk but thought id get this lunch time and then fit tonight, but competitor as is the case v often just says "normally in stock" against items - they hadnt got the coolermaster - only the 1200 / 1250 watt version and i didnt want that, so I have ordered from OCUK the

**B Grade** Be Quiet! Dark Power Pro 750W ATX2.2 Modular SLi C

Thanks for all the advice lads - im just a bit worried it wont be enough but the internet posts around the place seem to confirm the general opinion here that it should be.... I mean min draws around 350w under load at the moment..... (with the voltage reader I have)

Ill let you know what its like when it (hopefully) arrives tommorow!
