Solved 7970 vapor-x.... 650W power supply? Tags: Power Supplies Graphics Cards Components Last response: May 18, 2013 10:51 AM in Components Share foip May 18, 2013 3:55:53 AM Hey guys, I have searched for an answer for this but haven't managed to find anything... I have recently purchased an HD7970 Vapor-X 3GB... I was under the impression that I would only need at least a 550W PSU to be able to run it. However, after looking at the specifications on the box and in the manual of the graphics card itself, it states that it needs a 750W PSU to be able to power it... I have an XFX Pro 650W Core Edition PSU, which comes with the 8-pin PCI-E cables (which is why I thought I'd be safe with this PSU)... Should I upgrade my PSU before fitting the card? I don't want to risk damaging anything as my new system is almost complete!!!

You'd be fine even on a good 500W PSU, and that is a very good PSU. foip May 18, 2013 10:51:25 AM Someone Somewhere said:I would guess that the 750W number is for CrossFire.

Thanks for your reply now, though. I have been sitting with it on my desk wanting to fit it all day not knowing whether I had to wait to buy a new PSU or not. Going to start fitting it straight away!
