Is anyone here running their Vegas on one 8 pin PCIe cable split into 2 6+2 connectors? I know daisy chaining can be bad but the cables that came with the PSU ( Corsair hx1000 ) are heavy duty compared to other PCIe cables with only one 6+2 connection.
I am running mine at the 2x8pin (technically 8 + 6+2pin) cables that came with my corsairs. don't you have enough of these? with the rm1000x there are 4 of these per psu.
Yeah I have 4x 8pin to 2x6+2pin. Up till now I've only been running 2 Vegas from the PSU using two cables per Vega. Just read a lot of horror stories regarding daisy chaining PCIe cables, although most of this is people using the splitters. I didn't find much info on wether it was safe to use one PCIe cable for each vega
I tried running a 56 off a splitter, seemed to work fine but it was just one. Next I will try two 56s off the same cable. Corsair CX750M. I am mining CryptoNight though, not EthHash, which is very gentle on power compared to EthHash.
I wouldnt run two Vegas on one 8pin cord from the PSU. Your options are either two risers or both plugs on one GPU.
It will handle it for sure if it is a quality PSU and cable.
Would I do it my self (again :p) ? No, unless your pc is in a highly fire retardant enviorment.
A quality 8pin cable is rated for 24 amps so around 290W. There is probably another 100w head room as well. So lets say 400w very max.
2 vegas should not be pulling above 200w, (250w peak maybe) from the pcie cables @ cryptonight.
But DO NOT DO THIS on a cheap bronze rated PSU. These use cheap crimp terminals and housings that will fail. On high end PSU's its doable.
