Problem With The ATX12V

[Hi P]

Motherboard: Gigabyte B450 Aorus Pro Wifi

PSU: Corsair RM850i

Cable: ATX12V

 

I have one weird issue, let's say I take the ATX12V cable, and name one end Shape A, and the other end Shape B.

 

Shape A fits in a PSU slot, Shape B does not fit in any PSU slot, therefore Shape A is the end of the cable that goes into the PSU.

 

The problem begins, the motherboard has the same shape of the one already connected in the PSU (Shape A), and Shape B does not have the shape of the slot in the motherboard and neither the shape of the PSU slot.

 

What's going on?

 

Update:

 

- So apparently the cable is named EPS / ATX12V

 

- The ESP side does not fit in the PSU.

 

- Both the motherboard and the PSU have ATX12V but theres not a cable with both ends like that included.

@KarathKasun can I just buy the cable or what do I do?

Need pictures of the cable ends.

I don't know if it's fully appreciated

 

The left one fits both mobo and PSU, right one neither

The right one is the MB connector, its split so that you can take it apart to connect to a 4-pin motherboard or leave it together for an 8-pin one.

 

It looks like the contacts are damaged and keeping it from fitting.

The problem is that one you are talking about does not have the shape of the slot in the motherboard

It fits though.

 

The keying of it will allow it to fit the board.  Where there are square holes on the MB, the connector may have some pins with cut corners.  These will fit fine.

Is that safe? I don't want to damage it

 

It would be like connecting the EPS end into an ATX12V slot, 100% sure this works?

You could always trace it out with a multimeter.

 

It should work fine though, its keyed so that it will fit ATX 12v or EPS 12v.  EPS 12v is backwards compatible to ATX 12v but not the other way around (power restriction AFAIK).

Thank you very much!

 

I hope it works

@KarathKasun Wait! one question, I just read that ATX12V should be 4-pin.

 

Does this mean I can just split my cable and connect the 4-pin side?

 

What happens if I connect the whole 8-pins?

Just plug all 8 in if the MB has an 8 pin connector.  It will allow for higher current draw, though nothing outside of HEDT really needs all 8.
