well so I assume you mean you have an 8pin connector that is not split into two separate 4 pins?

CPU: R7 5800x (PBO undervolted)

GPU: 7900XT

RAM: 32gb Kingston Fury @ 3600mhz

MOBO: Asus ROG B550 F Gaming Wifi

You should be able to as long as there is no capacitors in the way it should be the left side of the connector. (plug it in with one side hanging off)

There are no PSUs which don't have either a 4pin or a separable 8pin. What is your power supply?

No I believe he means its a 8pin that is connected together (sometimes happens on higher end Psu's)

Use the left side of the connector in the 4 pin if it fits you should be good

And I said such PSUs don't exist. Specifically, all PSUs either have just a single 4pin, or a single 4+4pin, or a single 4pin and a "connected together" 8pin, or two or more 4+4pin cables, which means any of these options makes no problems with a 4pin mobo.

Like on which ones?

I asked for the model of your power supply.

Maybe he misplaced the cable or got a used psu. anyway the post above shows exactly what I was saying and this pic shows how the pinout is the same on ither side except for the shape

You should post what model PSU you have, and possibly what model motherboard

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k - EVGA Z370 Classified K - G.Skill Trident Z RGB - WD SN750 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G3 650W - dual booting Windows 10 and Linux - Black and green theme, Razer brainwashed me.

Draws 400 watts under max load, for reference.

 

How many watts do I needATX 3.0 & PCIe 5.0 spec, PSU misconceptions, protections explainedgroup reg is bad

it took only 13 posts to deliver essential information that should've been in the OP, or even in the topic name. Ok...

Just like I said, your PSU is no different from others. Its CPU power cable splits in separate 4 pins.

sorry, after i re-check it it is indeed splitable

so does that mean "as long as it can be plugged in then it is ok" rule apply?
