Posted March 2, 2014 Because that PSU is powering the 3 cards solely? It doesn't have to power the CPU, fans, hard drives, optical drives etc etc :lol: Corsair 400R, i7 3770K @ 4.5GHz 16GB, Corsair Vengeance 1600MHz, Gigabyte Z77X-UD5H Motherboard, 240GB Samsung 840 Evo Sata III SSD, 2 x Asus GTX 780 Direct CU2 SLI, Corsair H100i and Corsair AX860i Platinum Power supply.

Posted March 2, 2014 He used 2 PSUs to power a CPU and 6 GPUs. I don't think your system has 1/2 a CPU and 3 GPUs. I assume you think that he has 3 GPUs on 1 PSU and 3 GPUs and a CPU on the other. Most Likely its 4 GPUs on 1 and a CPU and 2 GPUs on the other. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
Posted March 2, 2014 Isn't Linus using a second power supply in the video? And you're OC is pretty heavy... imo Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
Posted March 2, 2014 Linus used a 850w psu to power 3* Gigabyte 280x's in this video -snip- and i'm using 2 cards and there's no more room for the other card. Dont be mad at me for the Title. Can't you see the other PSU that is powering just the GPU's... Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
Posted March 2, 2014 Linus used a 850w psu to power 3* Gigabyte 280x's in this video and i'm using 2 cards and there's no more room for the other card. Dont be mad at me for the Title. He used two PSUs to power 6 R9 280s and only one CPU and Mobo. That's a total of ~1700W -200W for the CPU and Mobo and peripherals to give you 1500W for 6 cards, approximately 250W for each card. The R9 280X TDP is 250W. You used two R9 280Xs which would be a total of 500W, and a CPU and mobo that will consume between 150W and 250W. That's about 650W-750W full load consumption for a system with two cards. You'd need at least 950W to power your whole system with 3 cards. I'd recommend at least 1000W.

Posted March 2, 2014 Author My card's are underclocked and cpu is taking no more than 40w at maximum and even if we take the 80w out for one hardrive, 2*fans and cpu (he must be using a hdd or something to even boot, lol) it still wont be enough. Btw the cpu is not overclocked right now. It's reversed it to stock before posting.

Posted March 2, 2014 cpu is taking no more than 40w at maximum what ? with that overclock the cpu is in the 300W zone. or more. a modest 4.x oc gets the cpu at over 200W of use.thats for sure. and corsair link is not accurate at all http://youtu.be/mgU8gSM38U0?t=5m52s Link to comment Share on other sites More sharing options...
