4+4 pin power connector work as a 8 pin power connector?

[Flowhomie]

I just bought a new PC which i need to put together myself, and my PSU comes with a lot of 6+2 pin power connectors, but none of them fit to make a 8 pin.

It does however feature 1x 4+4 pin power connector, where one of the 4 pins fit perfectly in half of the 8 pin socket.

The other 4 pin power connector har 4 sticks with rounded edges, but the socket has 2 complete squares and 2 rounded corners.

The connector will fit, but are the rounded edges designed to go into the squares as well?

Please help, this is my first build.

If you are referring to the 4+4 CPU power cable, that is what it is designed for. For use on a 4 pin header and an 8 pin header by putting them together. Never use the 6+2 pin connectors. They are for the gfx cards only and have their connector wired in reverse polarity from the CPU power header.

Yes it's still fine , just make sure they latch securely.

No, they should key up identical if you are using the correct cable and inserting it in the correct way. Be sure the cable's locking clip is on the side the header's locking nub is.

They should go over the latch , they only fit one way.
Clip over latch.

I wasn't answering this question > Even if the rounded corners go into the squares?

I was saying 4+4 is ok to use.

That 8 pin PCI-e is identical to the one on my motherboard, and the 4 pin fits perfectly into the right hand side of it.

The other 4 pin fits as well, but it has only sticks with rounded corners on it.

My PSU doesn't have the identical 8 pin PCl-e cable as the one shown on your picture, and it is not an old psu, its quite new to be honest

Tell us the make/model of the PSU and the make/model of the motherboard.
The purpose of the pic was to show you the polarity difference between the PCIe and CPU power cables. I guess I could have chosen a better example.

Connectors:
1 x Main connector (20+4Pin)
1 x 4+4 Pin ATX12V / EPS12V Your 8 pin. 😀
7 x Peripheral
8 x SATA
1 x Floppy
4 x PCI-E

That PSU should have 4 x 6+2 pin PCIe cables for the gfx card only.

It should have an 8 pin for the MB CPU header as well as a 4+4 pin header for the same. They are wired the same but keyed slightly different. If you put the 2 x 4 pin together, it should match the MB header.
