Two PSUs, one mobo

Humaj19 · August 26, 2021

Or maybe two motherboards, in order to get both to function. I think I saw a simple enough exploit (to get a PSU to work as if it were connected to a mobo) on YouTube, but I don't think it applies to all PSUs. I think I could also use a PSU tester, but I'm not sure that's a good solution for months at a time.

I have a 255W PSU, and I have access to similar low-wattage PSUs. If they're decent quality, can I plug one into a GTX 1080 and one into everything else? Everything else being something like an X570 Aorus Elite WiFi, a Ryzen 5 2400G (yeah, not an ideal match for a 1080 in most use cases), CPU cooler, case fans, etc. I think the main (potential) issue is that the GPU would be drawing power from both PSUs (one indirectly). Is that a problem? Each PSU would be sending power to the GPU without "knowing" what's going into the GPU at the other "end."

Really, just get. single good psu here. Don't risk the hardware with this sketchy setup

Does the psu have a pcie power connector?

That's just not a very good idea. Save yourself the hassle and get a proper power supply.

It involves the use of a paperclip, and it works on all standard power supplies. Still, don't do that here.
