Hey Everyone,
The new Epyc Supermicro boards come with this weird power setup: they have both an 8-pin CPU plug and a weird, proprietary-looking port (PJ1) that comes with an ATX adapter (CBL-PWEX-1063). I believe the Xeon D-2100 boards have the same setup:

Question: Can I use a 20-pin ATX cable (like that found on the PWS-203-1H PSU) with this adapter for the PJ1 port? Like so:1.6 Power Supply
As with all computer products, a stable power source is necessary for proper and reliable operation. It is even more important for processors that have high CPU clock rates. It is strongly recommended that you use a high quality power supply that meets ATX power supply Specification 2.02 or above. It must also be SSI compliant. (For more information, please refer to the website at Industry Reference | SNIA). Additionally, in areas where noisy power transmission is present, you may choose to install a line filter to shield the computer from noise. It is recommended that you also install a power surge protector to help avoid problems caused by power surges.
Note: The M11SDV-4C/4CT/8C/8CT/8C+-LN4F motherboard supports either 12V DC in power input or ATX power input. The 12V DC IN power input requires an 8-pin 12V DC IN connection to the JPV1 header. ATX power input requires an 8-pin 12V connections to JPV1 header and PJ1 a 4-pin power connector of an ATX power supply by power cable (24-pin ATX to 4-pin power cable for PJ1, Supermicro P/N: CBL-PWEX-1063). PJ1 allows motherboard control of the 5VStby, power on, power good, and ground signals from the ATX power supply.
