What is EPS pin?

The EPS connector is meant to supply power to a motherboard cpu socket while the PCI express connector is meant to supply power to a GPU. You shouldn’t be able to switch between them – the square and rounded off connectors are arranged such that you can’t.

What is the 24 pin power connector for?

A power supply with a 24-pin connector can be used on a motherboard with a 20-pin connector by leaving the four additional pins disconnected. However, if you have a 24-pin connection on your motherboard all 24-pins need to be connected.

Is the 24 pin supposed to be missing a pin?

This empty pin on your 24 pin connector used to be home to a wire carrying -5V. Since around 2003 the -5V rail was removed from ATX specification and as a result most modern power supplies do not include it.

Do you connect 24 pin and 8 pin?

You need to connect both 24pin and 8pin. 24 pin is main power for motherboard. 8 pin is power for CPU.

Do I need 8 4 eps?

The 4 pin is only necessary if you are doing extreme overclocking, such as LN2. Otherwise the 8 pin will provide all the power you will need.

What is an 8 pin EPS cable for?

8-Pin EPS extension cables are a great way to improve the overall look of your computer without going through the hassle or expense of a fully sleeved and single braided PSU cable set. Simply attach the 8-Pin EPS Extension to your existing cable set and you’re ready to go.

Can you use a 20 pin on a 24 pin motherboard?

“… you can plug a 20 pin cable into a 24 pin motherboard and it will work just fine. At least, it will for a while. They added those extra 4 pins for a reason. When you plug a 20 pin cable into a 24 pin connector you’re not providing the extra current carrying capacity which may be needed by the motherboard.

What is the difference between 20 4-pin and 24 pin?

The 24 pin motherboard connector is actually just the 20 pin connector with 4 extra pins added on the end. The original 20 pins were unchanged. The extra 4 pins are not separate rails. They’re just extra lines to provide more current to the same rails.

How do you connect a 20-pin to a 24 pin motherboard?

Technically, a 20-pin ATX connector can be plugged straight into a 24-pin motherboard socket, leaving male pins 11, 12, 23, and 24 unconnected. The four pins that you are leaving open are just redundant lines for higher current capability (see this guide to ATX connectors and pinouts).

How do I know if my PSU is failing?

There are a few telltale signs of a computer power supply that may be failing….Typical symptoms include:

  1. Random computer crashes.
  2. Random blue screen crashes.
  3. Extra noise coming from the PC case.
  4. Recurring failure of PC components.
  5. PC won’t start but your case fans spin.

Can a 4 pin ATX connector work on the 8 pin ATX motherboard?

It is entirely possible to just plug the 4-pin connector in the 8-pin slot. It won’t damage anything, but the motherboard will detect the difference and either not start up at all, or run in a VERY restricted mode.
