Can I Power My 2x4 ATX Motherboard with 2x3 PCIe and 2x2 ATX Connectors?

Asked by TechWhiz77
I have a motherboard that needs a 2x4 ATX power connector, but my power supply unit (PSU) only has a 2x3 PCIe and a 2x2 ATX connector. Is there a way to use these to power the motherboard? I'm just trying to see if a spare motherboard and PSU I found in my house will work together to power up my setup.

What power supply and motherboard are you working with? Are you sure that your motherboard requires two 8-pin power cables and you only have one? Let me know, and I can help you better!

TechWhiz77: The PSU is an Nox AT-500P12P, and the motherboard is a Gigabyte GA-Q35M-S2. I only have one 8-pin.
