Can A 20 Pin Power Supply Be Used On A 24 Motherboard?

Can I use a 24 pin power supply on a 20 pin motherboard?

If you plug a 24 pin power cable into a 20 pin motherboard then it will work fine but you often can’t get them to physically fit together because something gets in the way.

If they don’t fit together then you can get an adapter cable which converts a 24 pin power cable into a 20 pin cable..

Why is there a pin missing on my 24 pin connector?

Most likely it is because the -5V rail has been removed from modern power supplies. If your power supply unit has an empty pin on the 24 pin connector (see picture above), then your unit does not have a -5V rail.

How do you test a 24 pin power supply?

Locate the 20+4P (24-pin) connector. Bend the paperclip and insert one end into the green pin (PS_ON) and the other into any of the black pins (Ground). Flip the switch at the rear of the PSU, and listen for the internal fan. If you can hear the fan, this should verify the power supply is turned on.

If you truly wish to experience your chosen motherboard and, in the process, identify any possible flaws in its performance, you’re going to have to hook it up to a CPU.

What is the difference between 20 and 24 pin power supply?

You can plug a 20 pin ATX power cable into a motherboard with a 24 pin ATX connector […] The 24 pin motherboard connector is actually just the 20 pin connector with 4 extra pins added on the end. … A 20 pin power cable only fits into one end of a 24 pin motherboard connector so you can’t insert it incorrectly.

What is the 24 pin power connector for?

An ATX power supply provides a number of peripheral power connectors and (in modern systems) two connectors for the motherboard: an 8-pin (or 4+4-pin) auxiliary connector providing additional power to the CPU and a main 24-pin power supply connector, an extension of the original 20-pin version.

Can you plug a 6 pin into a 4 pin?

No, the 6-pin connector is only for PCIe device and would fry your CPU/mobo. You PSU has a 4-pin connector (all ATX PSUs in the last 8+ years do). It might be a 4+4 pin plug… the plug can split in two. Otherwise, plug the 8-pin EPS into the 4-pin ATX12V plug… it will fit.

Do you need both 24 pin and 8 pin?

Both should be plugged in. You need both. The 24 pin is for the entire board (RAM, PCI/PCI-e slots, fan headers, Chipsets etc), the 8 pin is just for the CPU.
