Hi, great post. I am interested in the cables, connections, etc. The board connectors are only 6 pin, but your Vega 56's are two 8 pin? Are you using a single 6 pin cable to 8 pin, so two cables for each Vega 56? I have read so many differing opinions on how many watts a 6 pin cable can take and what an 8 pin plug requires, etc, so Id be very interested on your take on this.
Kind regards.
A 6-pin can handle more then 75 watts of power. For example if a 6 pin were restricted to 75 watts then we would be getting 2.08A per 12v yellow cable 2.08*3*12 = 75 watts , but awg 18 are able to deliver up to 10A per yellow under optimal circumstances , so theoretically 10*3*12= 360 watts. But thats the cable then we have the terminals..
Standard terminals are rated for 8amps then there is HCS terminals that are rated for 11amps and Plus HCS terminals 12amps
so with a 6-pin pcie with 2*8*12= 192 watts from 6 pin pcie 18awg
8-pin pcie with 3*8*12= 288 watts 8 pin pcie 18 awg
So 6 pin 75 watts of power rating are vastly underrated.
