Your motherboard shows an 8 pin connection near the top right

and your PSU shows two 4 pin CPU connectors:

You are right but the CPU1 power cable that has 4+4 pins doesn't fit in the CPU . That is because one of the CPU 4+4 power connectors have [2 SQUARED PINS AND 2 ROUNDED PINS ].The other 4 pins have [4 ROUNDED PINS] that's why only the first 4 pins can fit in the socket but the rounded pins cant. The PSU has 2 types of 4 pins because it was made to be plugged in a socket that either has 4 rounded pins or (2 SQUARED and 2 ROUNDED PINS)=4 pins but not both in one socket.

You didn't connect your 4+4 pins good probably. 2 hooks need to be in middle and it will give you proper 8 pin.After that just rotate that 8 pin to see from which side it will fit.It also can work fine with 4 pin just connected to motherboard.

I know what do you mean but Believe me they are different 4 pin connectors I saw that. I tried everything. Except breaking the port.....

Ok try to put 4+4 side to PSU and 8pin one to mobo.

I did that bro. I thought that way. Still doesn't fit in both.One end fits in one of the ports the other end doesn't fit at all. I am thinking of buying this adapter https://www.amazon.com/gp/aw/d/B00P0BFPQI/ref=mp_s_a_1_4?ie=UTF8&qid=1474239198&sr=8-4&pi=AC_SX236_SY340_FMwebp_QL65&keywords=4+pin+to+8+pin+cpu+power+adapter&dpPl=1&dpID=41C6y0-vzyL&ref=plSrch

If cable fits from both sides to PSU then there is problem with motherboard connector. Try to see if something fell in and doesn't allow you proper connection.
What CPU are you using??

I gotcha but I cant describe. Please leave your email so I can send you some photos of the connector.

Only 4 pins can fit the cpu port and the same pins fit the PSU. But the problem is that the other 4 pins doesn't fit in any port.

You can post photos here so all of us can see it.

You are doing it wrong. The connector of the motherboard has one square more but still, the 4pin connector will fit with this one rounded pin and have to.

the 4+4pin is 100% compatible to the EPS connector


post photos through an image hoster of your choice and post the link of it

Bro I am not stupid! I saw every single pin and they are not the same. This problem is from the PSU thats why I need an adapter.

Does the motherboard 8pin look the same as those online? Can rule out a factory error.

I´m not telling you that you are stupid, you are not. Had myself a very equal situation and can fully understand your problem

upload the pictures to e.g. https://postimage.org

you could pin out the false plastic connectors and get the correct one. Be careful doing so, the wrong pinout could damage your system.

[helpstar]

is there another cable which you could plug in in the CPU2 port of the PSU?
