PC is Shutting down from Windows 11 have to pull plug to reboot

Thinking this 4 pin has to be a legacy CPU connection that is now a 6 pin on the majority of power supply's so plenty of options on the Mobo and no spliced cable, lets see how it goes.

From what I can see they have spliced a 4 pin molex connector into the 24 pin mobo connector im assuming because there is no 4 pin on the mobo I just cannot figure out what the 4 pin is doing. Excuse my crappy pics all that's happened is they have wired it into the top 4 ports on the 24 pin, the ribbon for the 4 pin is under the 24 took me a while to find it

My brain is completely boggled by your description and the pictures :cry:

I can only explain it in the terms that I understand.

In picture 1: I think that picture is the PSU's modular board? Is that correct? If so, then this board and all the plugs/sockets are proprietary (all modular boards are proprietary), so only Kolink can explain what they're doing and why, because I have no idea.

In the second picture, that's the motherboard, right?

I think I can see what you mean with the spliced connectors with two wires, but I don't know what that's about either.

In reference to a 4 pin being a legacy CPU connection which is now a 6 pin, are you referring to the modular board here? There's no legacy anything with a modular board, because there's no standardisation.

You're right that a 4 pin 12v connector is considered a legacy CPU connection (it is now more commonly an 8 pin EPS 12v), but that's only on the motherboard side, not the PSU side.

Sorry Tetras its been a long time since I had to think or explain anything this way and TBH I am just way out of practice and more than a little out of touch, its kind of why I had this rig built by OcUK instead of doing it myself.

So yeah Pic 1 is the Power Supply Kolink unlike some don't label their PSu but that first connector I indicate is a 4 pin for the molex and next on the PSU to it is the standard 24 ...... Both of those splice together at the MOBO end into the 24 pin

On some of my older MOBO;s I think there used to be a 4 pin molex connection next to the CPU that was plugged in I think to provide Juice specifically for the CPU (I think) and there was a 4 Pin Molex for that on the PSU unit as they basically had cables for everything unlike these newer models

I just don't know what the 4 pin connector on the PSU is actually supplying power for on the MOBO, I have unplugging it and it does not seem to have made the slightest difference to usage and performance all my editing and games seem to be running just fine and TBH not had a single outage since I unplugged it

If it is spliced into the main 24 pin then I would assume it supplies additional power for this connector. Why Kolink would specifically do that with only 4 of the pins, I don't know, it might be because of what those pins supply and how the PSU feeds them, because the 24 pin has a lot of different ones if you look at a pinout. It might be for the standby power, or because it comes off of a different rail (e.g. 3.3v)?

Yes, but this is still the case. The 4 pin near the CPU is just an 8 pin nowadays, it still needs it. From what I can gather, you're making a connection between the pins on the motherboard and the pins on the PSU, but that's where you're going wrong, because there is no connection. What matters (in terms of what it is for) on the PSU end is something Kolink can answer. The fact it looks physically identical to a 4 pin on the PSU end, may have no association whatsoever with the 4 pin you're referring to that powers the CPU, especially since it appears to be spliced into the 24 pin. If the other end was hanging loose somewhere near the motherboard, then I'd agree that's what it was for.

I was thinking that I could email Uocuk Tech support or something as in the end they would have been the ones to actually plug all that in and may know why they did it.

Not really an issue gong forward as new PSU is here later today


EDIT>> So I had a look at the MOBO manual and it tells me there are 2 x 4 pin connectors under the Fan housing (cant remember the brand of the fan but it covers these 2 connectors) 1 is for CPU fan and 1 for AIO fan, im wondering if this was done as a way to work around that, although with the 4 pin unplugged at the PSU end the fans all seem to be working fine so maybe not.

EDIT> Found some pics of the PSU and there is a shot of the 24 pin cable it appears that it ships as standard with the 24 Pin and 4 pin as one. Wonder is someone was just being neat and plugging it in as it would just sit there looking lonely if left unplugged its just described as a 24 pin mobo connector no mention of the +4

EDIT > Appears it's not a power connector itself, it just enables the voltage sense feature and again I am unsure what that is ...should just go buy an Xbox :) .

the extra 4 pin pig tale is part of the 24pin arrangment, i know of only 1 other manufacture to do this at thats silverstone, they require you to have that plugged in for proper operation of the psu and pc, Kolink sends shivers down most peoples spines when mentioned, they are the bottom of the bin psu's, so many problems over the years on the forums.

with regard to your crashes after a few hours and thinking its a overheating issue, how have you got case airflow organised? ie front fan(s) intake and rear top exaust?, seeing the pictures you have posted above i would have a look at a cleaning of your rig, there does seem to be a fair coating of fine dust that will act as a insulator to all your components making them run warmer than usual.

check case airflow and adjust fan rpm's to account for when the pc is under load in a game etc, if you still have problems i would look at a case swap and plan out extra case fans to help keeping things cool, also make sure your case has good ventilation too dont have it up close to a wall or corner, if the heat cant escape effectively that will case all kinds of headaches.

You said that you followed the 4 pin wires and it is spliced into the motherboard 24 pin, yes? So, no, it is not related.

What you're describing is, I believe, 4 pin fan headers (PWM headers) and these don't connect directly to the PSU. They go from the fans to the motherboard, since the motherboard provides the power for these directly. They're very different physically to a 4 pin (2x2) block, since they're much smaller/thinner and arranged in a line, 4x1.

Your spot on I found a better manual online and it is the linear 4 pin ones so that scratches that idea. I would just love to know what it is although after the weekend Im hoping it wont matter. ..... hope.
 
computer shut down so many times that I couldn't use it ...so changed PSU and I have to say it was so much easier as I only had to match the cables that were ll neatly marked with the corrosponding one on the PSU, there was an old 8 pin plugged into one on the mobo marked EATX12 V and all I had was 2 cables marked cpu so took a chance and used one of them

Just going to fire up Sniper Elite and see how it goes. will be back in 2 mins or 2 hours if it works
 
Well just had a 30 minute play and that's 29 minutes and 50 seconds longer than usual so seems promising, New PSU seems great and super quiet and me I could not be happier although I am disappointed the Kolinik ended up in my PC at all but such is life

Thank you everyone who helped and extra thanks to Tetras for the help and recommendation very much appreciated:)
