Can handle HD 7950 CFX?

post #1 of 5
Thread Starter 
My entire rig it's:

i5 3570K (Default clocks)
Z77X D3H Gigabyte.
Corsair Neutron 120GB SSD
Caviar Black 1TB.
HD 7950 (Default clocks)
8GB RAM
3 fans


The PSU: Corsair TX650M.

Thanks

Leave the cards at stock clocks with only an overclock on the cpu, then you'll be ok.

Thanks for the help. I think i wouldn't OC the GPU's / CPU.

Let's see what say other's people thinks about it.

Should be fine. OC and upgrade the power supply for more performance if wanted.

Power Consumption

Let's have a look at how much power draw we measure with this graphics card installed and overclocked.

The methodology: We have a device constantly monitoring the power draw from the PC. We simply stress the GPU, not the processor. The before and after wattage will tell us roughly how much power a graphics card is consuming under load.

Our test system is based on a power hungry Core i7 965 Extreme Quad Core / X58 system. This setup is overclocked to 3.75 GHz. Next to that we have energy saving functions disabled for this motherboard and processor (to ensure consistent benchmark results).

We'll be calculating the GPU power consumption here, not the total PC power consumption.



Measured power consumption default card
1.System in IDLE = 165W
2.System Wattage with GPU in FULL Stress = 300W
3.Difference (GPU load) = 135W
4.Add average IDLE wattage ~3W
5.Subjective obtained GPU power consumption = ~ 138 Watts

Mind you that the system wattage is measured at the wall socket.

Measured power consumption overclocked at 1020 MHz (no voltage tweaking)
1.System in IDLE = 165W
2.System Wattage with GPU in FULL Stress = 309W
3.Difference (GPU load) = 144W
4.Add average IDLE wattage ~3W
5.Subjective obtained GPU power consumption = ~ 147 Watts



Measured power consumption overclocked at 1150 MHz (with 1.25 Volts)
1.System in IDLE = 167W
2.System Wattage with GPU in FULL Stress = 381W
3.Difference (GPU load) = 214W
4.Add average IDLE wattage ~3W
5.Subjective obtained GPU power consumption = ~ 217 Watts

Mind you that the system wattage is measured at the wall socket and the GPU 100% stressed.




You will be fine. Although you will have to use the molex connector adapters :/
