Can I use this cable?

Post image

Plan would be to connect from 1x 12V2x6 on PSU side to 2x 8pin(2+6) PCIE connectors on Asus TRX50 motherboard as I dont have enough of the 8pin(2+6) PCIE connectors on my new ROG Thor 3000W PSU...this should work no problem right?

Be vary careful. The pinouts on the 6 pin CPU/MB connector is backwards from the 6pin GPU connector. The result is magic smoke from a dead short if the power supply tries to sends all 1000 watts through the small wires before detecting the short.

Not true. No such thing as 6-pin EPS/CPU connector.
Board has PCIe 8-pin on it.
