This is a part from an IBM server dated 2008 that I want to reuse in my new computer. It essentially converts from 1 SAS port to 4 SATA ports. I’ll use the raid card to connect to it via SAS, but I do not know what the power port is and what the connector on the top is either
Looks like a cpu/gpu type power connector. Even if its a standard plug does not mean its a standard pin out ! Craft computing on YouTube had what looked like a standard plug in his server but it had a 12volt and ground switched, so would have caused some real damage
