Mining rig with Sapphire Rx Vega 56 Nitro+

[shanticlaws]

Hello!

I'm contemplating building a new mining rig with Vega 56's, the Sapphire Nitro+ version is going to be available soon, and I'm thinking that might be a good one to use. They're big and bulky, but should run cool and the size isn't an issue.
However, it needs 3 8-pins connectors per card! Any ideas as to how I should go about that? I want to run at least 8 cards, but that'd be 24 8-pins connectors. Are that many connectors really needed per card considering I'll undervolt?

Thanks!

If it helps, I've read that the 3rd connector is optional and only used if you're literally super clocking the card past regular OC limits.

You can use something like that https://www.parallelminer.com/product/platinum-1200-watt-200-240v-power-supply-kit-for-gpu-mining-zec-dash-eth/, just buy 2 of these
One with 16 6+2 connectors and the second one with 8 6+2 connectors

Also, you can use a PICO adaptor with server PSUs to ditch your ATX PSU completely

If he buys two of those he will have 2400w to use

Thanks, I've been looking at getting a PSU from parallelminer. But since I'm not in the US, the total cost including shipping and customs would come out to about what I have to pay for two Corsair HX1200's here. I'd prefer the HP's since I could power more cards, but the Corsairs are silent and have 10 year warranty.

The HX1200 has 8 6+2 connectors, so if I don't need to use the third connector on the Nitro+ I should be good. Hopefully.

Hi!

I'm gonna go ahead and hijack your thread a bit. Did u get your cards?
I'm wondering if Sapphire locked the firmware for bios on theese cards?
I can't seem to find any modded bios-versions for this and polaris bios editor does not even want to open the bios. Or is it simply that it's so new noone has modded the bios yet?
For some reason trixx does not want to acces the card either, is wattman the only overclocking option?

peace
