Hi guys, i have a HD 6870 with an xfx 550w pro series and i want to upgrade my gpu to a HD 7970, is it possible to use the same PSU? My configuration is:

AMD Phenom II x6 1090T AM3 Black edition 3.2 GHZ
XFX Radeon HD 6870 1GB GDDR5
2x2GB Geil Value plus DDR3 1600MHZ (GVP34GB1600C9DC)
XFX Core edition 550w - P1-550S-XXB9
Asus M4a88T-M/USB3

Remembering that my psu has 2x 6 pin pci-e not 8 pin.

Thanks!

I am guessing you will push the power envelope when you add that 7970. I would purchase a new psu first. I recommend Seasonic.

ah according to XFX:

Fixed 6+2-pin PCI-E:1
Fixed 6-pin PCI-E:1

you have a 6 and 8 pin (6+2) PCI power connections. and that PSU will handle a 7970 w/o any problems.

the 7970 will run perfectly fine no problem. Your total system power consumption will be about 300w max with both cpu and gpu loaded. The XFX 550w is more than enough.
