hello,

im wondering is it possible to use an XFX 7950 and a XFX 6870 is the same rig.
i dont mean crossfired together, i just mean use them both without a bridge.
the 7950 on a 32" hdtv (1920x1080) and the 6870 on a 17" monitor (1366x768 i think)
i already own a 6870 and my 7950 is getting deliverd in two days.

idea being that when im gaming ill get the full memory etc from the 7950 while on the other monitor with the 6870 watching a film

thanks for any and all help
marc

Make sure your PSU is able to handle both cards, although it does not sound like you will be running both of them at full load.

lol ino that, im planning on buying a 1050watt psu next week at some point then setting it up. and no the 6870 will never be at full load, only browsing and watching films etc,
cheers

Hmmm, 1050W? Make sure it's not a Diablotek; that PSU-shaped object was found to be a 500W-550W PSU by testing at Jonnyguru.com, where I believe it even fried some of their test equipment when it choked, smoked, and CROAKED.

you don't need a 1050 watt PSU; the combined power for both cards are at most 310 watts (145+165) being used with two 6 pin (6870) and one 6 pin and one 8 pin (7950) PCI power connections. a quality 650 watt will handle that, no problem. add 150 watts for the system (a bit of an overestimate) and thats 460 watts/12 volts for 38.3 amps. to keep it under 80% load 38/.8=48 amps.

XFX Core Edition PRO650W $89.99
+12V@53A | 2 x 6-Pin, 2 x 6+2-Pin

Hello Marcd2011,

A 1050Watt Power Supply is extreme overkill for your needs and cause; your better off saving $30-50 and putting that towards other hardware (CPU, GPU, RAM, or a SSD).

Max Power Draw:
6870 = 151Watt
7950 = 200Watt

Source:

Even assuming if they reach max Power draw that's only 351watts. A quality 750W Power Supply is more than enough for your need.

I highly recommend the Corsair 750Watt Enthusiast Series V2. This series has a legendary track record and solid build quality.

Warmest Regards,

PS: If your unsatisfied with the 750watt Model. Go for the 850Watt model, however this is still overkill as you can easily run two AMD 7950 at max power draw in Xfire with just the 750Watt Model.
