8-pin Connector

8-pin Connector
« on: June 15, 2016, 11:36:27 pm »
There's an 8-pin power connector on the GA-990FXA mobo. I'm having a hard time finding a PSU to match that. Should be simple. But the corners are shaped different on various connectors. The last PSU I got had the 8-pin connector. Others have 6+2 or 4+4 connectors. I bought a 4+4 but that doesn't fit. And I can't find just an 8-pin PSU.

My last PSU was an Ultra LSP 650 which is gone now. 500-600 is really all I need.

Does anyone know how this connector is labeled or a suggestion for a PSU? I just know it as a 12v 8-pin.

Can I use the 6+2 pin connectors?

I'm pretty sure that the 4+4 pin connector is the one that should fit. This provides backwards compatibility to older motherboards that just had a 4 pin connector for the cpu power. Note that the orientation of the connector is important - it will only go in one way and if you don't examine the connector and socket very carefully, this can be easily overlooked.

Hello,

Do not try to place a 6+2 pin connector into the motherboard.

Which PSU do you have?
The 4+4 pin is the right one and as rinkol said, you need to check which way round you are placing them.

Change the order, they should have clips to help get the right way round.

Yes, the 6+2 is working fine here with my Seasonic 650W - just watch the coding .. it fits only 1 way (each plug)

Please don't suggest that a PCI-E 6+2 pin connector will function fine into a motherboard 8 pin socket.
This is completely wrong and will cause damage if you actually manage to force it in.

  • The CPU 4+4 or 8 pin EPS has the 12v wires (yellow) along the top edge.
  • PCI-E 6 pin / 6+2 is the opposite way, 12v wires along the bottom edge.

If interchanged you would effectively reverse the voltage supply and something will stop working.

Here the 8pin socket is on the GPU card and not the mobo, anyway, in fact the internet is full of using the 6+2 = 8pin okay!

I am not sure what's your problem? misunderstanding perhaps?


Here a photo from my card fed by a 6+2 (there is another 6+2 dangling right beside)

This is a motherboard thread, the OP is asking about the 8pin EPS connector on the motherboard.

So what you have said does not apply and is completely wrong, this is not about a GPU.
