Motherboard PSU connection

Recommended Posts

Posted · Original PosterOP

Hi,

 

I'm looking for a new power supply for my system. I have the MSI X470 Gaming plus max motherboard that has an 8 + 4 pin connector on top for the CPU power.

I'm browsing for power supplies but I don't see any PSU mentioning that it has these connectors. What are they called? On a product page all I see is something like this: 

1x 20-pins ATX or 1x 24-Pin-ATX12V-2.x, 1x 4+4-Pin-12V, 1x 4-pins 3.5", 8x 4-pins 5,25", 4x 6 + 2-pins PCIe, 9x 15-pin SATA

 

I assume the 1x 4+4-Pin-12V would be the 8 pin connector that you can split in to 2 four pins right? I don't need the other 4 pin connector on the right since I'm not planning to overclock that much anyway.  

 

Just asking to be sure in case I buy a power supply that only has the 4 pin connector :/


CPU: AMD 3800X GPU: GTX 1080 Ti RAM: (16GB) 2x Corsair 8gb DDR4 3200Mhz Drives: SanDisk 240GB SSD, Samsung 500GB SSD, WD 1TB HDD

Motherboard: MSI X470 Gaming pro plus PSU: Gigabyte 650 watt Monitor(s): 27 inch AOC 1440p

That's exactly what it is. An 8-pin connector that has a little clip in the middle so you can split it in half. Most modern power supplies have everything you'll need for a given system, so I wouldn't really worry about it.


Always remember the 80/80 rule of project management. That is, the first 80% of the project takes 80% of the time, and the last 20% of the project takes the other 80% of the time.

The extra 4-pin is not required.

Only needed when you are pushing EXTREME overclocks (e.g. under liquid nitrogen or dry ice cooling).

 Typical Air / AIO / water cooling won't even come close to using up all the power the 8-pin power can supply.

 

You need the 8-pin (4 + 4) connector is required, but the remaining 4-pin is optional.

The 8-pin connector is called EPS12V, the 4-pin ATX12V. The 4+4P is a combination of these two formats. Only one part of this split connector will fit the ATX12V (not both, don't use force to get it in), both together will fit the EPS12V.
