Title: Building Zcash Rig - questions on power consumption Post by: VoskCoin on May 04, 2017, 10:54:06 PM If I have 5x Sapphire Radeon VAPOR-X R9 280X and 1x Nvidia 1080 TI what are some of my best options for a PSU?
https://www.newegg.com/Product/Product.aspx?Item=N82E16817151102 I have this currently but I imagine this will not be sufficient for all 6 cards only 5?

That's 1500 watts of juice right there from your GPUs alone. You can undervolt, reduce the power limit % etc, but you still will need a beefy PSU to handle those 6 GPUS. You also need to make sure you have enough PCIE connectors since the GTX 1080 Ti uses 2 and at least some (maybe all) R9 280Xs use 2 connectors as well.

What psu for the six cards then?

So then I should simply run 2 PSU? like 2 of the link I posted in OP?

I recommend a setup like this --- http://www.parallelminer.com/product/all-aluminium-6-1-gpu-open-air-mining-case-w-6-usb-risers-1-1200w-psu-kit-eth-zec/ --- with a smaller ATX style PSU to run the motherboard, CPU etc and 1-2 GPUs, with the other GPUs off the server PSU. Get one of these also to make it allot easier --- https://www.amazon.com/Add2PSU-Multiple-Power-Supply-Adapter/dp/B009P98Q8U --- makes both PSUs act as one when you turn your rig on.
