The ETHOS IRC expert suggested I’d get more power stability using the 8-pin express connectors to my GPUs. My Zotac 1050ti’s have 4-pin IDE connectors. But there doesn’t to be such a a thing as an 8-pin express to 4-pin ide connector.All the connectors like that I see are missing the 5v (red wire) IDE connector. Which I guess makes sense, since the VGA 8-pin EXPRESS spec looks like it has only 12v and gnd.
So I thought well, perhaps the GPU only requires 12v, and tried it. The fans don’t even spin up , so I assume 5v is also needed?
Some of the GPU’s have a 6-pin express, which are connected to the 8-pin express directly on the PSU, and those work.
Others go from the express on the PSU to a SATA connector then to 4-pin IDE with a red wire. Which seems odd because I don’t see 5v offered on the VGAS or CPU specs for the PSU specs. So how does SATA get its 5v? Voltage divider?
