Think that entirely depends on the quality of your 650W supply. Techpowerup managed to get their 6870x2 to draw maximum of 353W using the powerhug virus Furmark, but 245W was their more realistic max draw running games:

You didn't mention the rest of your specs but gaming should be around max 260W or so(note that their single 6870 is 128W: one x2 card should generally draw a bit less than two more normal ones), so you should be fine.
sorry my psu is a 650W Corsair TX650 V2 80PLUS Bronze Power Supply , the rest of my system specs are listed under my system
Oh, sorry. Think you should be fine: if we take the 1075T's power consumption from Hexus's 1075T review (full system already with a HD5870):Originally Posted by Elspuddy

That's at the mains so PSU efficiency comes into that - so possible more like a 150W load on the PSU itself. But anyway lets be generous and round that up to 180W and add two HD6870@130W brings us to a total 440W. Plus a few W more for your HDDs but chances are the system will seldom actually have 100% CPU, GPU and HDD usage so even 450W is something you are unlikely to actually ever draw.
