Could my PSU Handle crossfire 6870?

Okay so I'll be getting another brand new ATI Radeon HD 6870 1GB very soon and I just wanted to know if my power supply would be able to handle two of them in crossfire, as well as the rest of my system with some spare space left so its not tight, e.g. 720W of 750W used.

PSU: XFX Pro Series 750W Core Edition Fully Wired (getting it RMA'd so it might change to a corsair but we'll see afterwards, will still remain a 750W however).

Rest of system is in my sig if needed

750W is more than enough.

Okay thanks. I read online that crossfire 6870s can peak at around 480W (which is 100% stress furmark)? ^^

just put your pc specs thru this psu calculator with xfire 6870s. recommended psu wattage was 518. so a 750 is giving you plenty of clearance

do you specifically need a psu designed for crossfire/sli or they just a selling point?? for example if you got enough wattage on a normal psu that would work??
