Title: Is my PSU good enough? Post by: mpradeep on September 03, 2012, 05:48:19 AM Hi all,
I am using a corsair 750W TX bronze 80+ PSU http://www.corsair.com/en/power-supply-units/tx-series-power-supply-units/enthusiast-series-tx750-v2-80-plus-bronze-certified-750-watt-high-performance-power-supply.html System configuration intel Motherboard with one PCIe x16 slot and 3 PCIe x1 slots 4GB DDR2(2x2) SSD 160GB HDD SATA 320GB HDD Intel-Core2-Quad-Processor-Q8300-(4M-Cache-2_50-GHz-1333-MHz-FSB) 95W TDP One 6950 with locked Bios OC version (830MHz Core and 650MHz MEM) --Hashing around 350MH/s To the above system i want to add a 7970 Gigabyte Mobo I want to make sure my PSU can withstand this. Can you please suggest if i can go ahead and make the purchase. I dont want to change rest of the system. Also i want to know how much a power does a 7970 draws from the mains so in case if i cannot support 6950 and 7970 i can swap 6950 with a 7970. Also i am planning to use 1x-16x extender to support the second GFX card on my Mobo thanks pradeep Title: Re: Is my PSU good enough?

200 TPD for 6950 500 TPD for 7970 95 for CPU and 50 for others i know both my GPU's will be operating at max load so i was worried if 750 would suffice??

Thanks Pradeep A 7970 does not use 500W. It is only rated for 300W at absolute maximum, and mine uses ~260, which is quite a lot from what I can tell. |
