Psu cpu connectors don't fit

[martinB]

Greetings 
I have very little experience and every computer I owned so far was a laptop so please don't be too harsh on me. Anyway I decided to build a computer myself. My motherboard is Intel s2600cp with two xeon E5-2670 processors and 32gb of ram for now. It's a server motherboard. The PROBLEM is I made a mistake when ordering my PSU.Initially I was going for EVGA SuperNOVA 750 G2,750W, Fully Modular, but what I got is EVGA 750W B3 fully modular. Main power connector fits just fine but it's impossible to connect cpu cables to 12V processor core voltage connector (2 x 4 pin) on my motherboard. Long story short my motherboard has two  12V 2x4 pin connectors and I can't power even a single one.My PSU has 1x  EPS/ATX12V 8(4+4) -pin (as it says in the manual lol).There are 2 cables marked with "CPU" on them but as I said the shape doesn't fit.  Are there any adapters that I could buy and use instead of purchasing a new PSU and selling this one? I will attach some photos and links below . Any help is appreciated

What connectors are these:

 

Is that the old power supply or something?

 

This cable looks like it would fill half of the white plug pictured on the motherboard:

Sorry, but you have to replace the PSU and send it back because you can not use that PSU because it is missing the second CPU Connector.

 

If you use it, it will destroy something due to overload of the CPU Cable. You must also not use the Adaptor!!

You need a PSU with two CPU Cables, that are 1:1 connected (ie no pin on the PSU side is used twice).

 

Sorry, but there is no other way that wouldn't cause any trouble, if you want to use both CPUs.

For a Single CPU System it might be usable but not for two.

8 pin EPS connector with two 4 pin connectors on its other end. With a dfferent shape layout (square , trapeze kinda thing).They are brand new, it looks like that just because of lighting haha. And yes, I can fit one 4pin into that motherboard cpu connector but the other one doesn't fit (to have both act as a 8pin) I don't think it should be like that and I don't want to accidentally fry anything. When I realised that I got the wrong PSU model I thought I would test everything with only one processor running, turns out I can't even properly connect that one. I thought 8pin was 8pin. I'm really lost in this terminology not gonna lie. Apparently instead of 8pin (2x4) I got 8pin (4+4) cables. I guess trying adapters and Y splitters is just not worth it, I'll just put it up for sale

A 8-pin CPU power connector IS an 8-pin CPU power connector.

 

A trapezoidal pin will fit in EITHER a square, or matching trapezoid socket.

A square pin will ONLY fit in a square socket.

 

 

 

 

Your motherboard requires two CPU / EPS 8-pin connections, so you would need a different PSU anyways.
