Hello, I am considering a setup for a 3x Radeon R9 280x rig, could You suggest me which other parts I should use? To minimize the cost, and be optimal aswell (so the GPU is the bottleneck)? Assistance from anyone who has similar setup would be even more helpfull ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

PSU would probably need to be 1000W to be safe.

Beware of the heat produced. You will need risers or external fans to keep them cool!

Awesome! Riser cables only for 1x pci-e slots, right? Is the only purpose of riser cable to allow cards to be further from each one, or PCI-e x1 slots need those to connect to PCI-e x16 card(which I doubt is necessary)? Beware of the heat produced. You will need risers or external fans to keep them cool!
Do You mean that those connected to PCI-e x1 need external fans, or each one (x16 slot one too)?

Do You mean that those connected to PCI-e x1 need external fans, or each one (x16 slot one too)? For more than 2 cards you might as well just use riser cables for all of them. You need to space them out because they produce a lot of heat even with the built in fans.

"wow I'm jealous!" isn't advice but it may be the answer you're seeking. If not I'm sure everyone will walk you through it b/c you're not feeling like using search/google. You should get 1 before you go all in ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif)

you'll want a 1200W PSU (just to be safe), if you go with the sapphire vapor X's you cant fit 3 side by side on most motherboards, and even if you could they will run too hot, so you'll need risers so they can be mounted elsewhere (and further apart)
I just use an amd a4 in my miners, don't need much cpu and 4G-8G ram.
You don't need a good motherboard just one with enough pci-e slots. I use the f2a85x-up4 in my miners but that's just because im familiar with the board and I like a few of its features. (its a tad unpredictable with risers though). You can use any type of pci-e slot, 1x, 16x etc, it doesnt matter just get the right risers (e.g 2x pci-e 1x to 16x risers, 1x pci-e 16x to 16x) I have a rig here atm with 3 280x's. 2 in 1x slots, 1 in 16x slot, all powered risers.

Does the slower PCI-E slots affect the hashrate? I mean is hashing faster on card connected via PCI-e 16x, and slower on those connected on PCI-E x1?
