So back during covid I ordered a system from UcUK
AMD Ryzen 7 3700X Eight Core 4.4GHz
ASUS TUF B450-PLUS GAMING
Sapphire Radeon RX VEGA NITRO 5700XT
Corsair Vengeance LPX 16GB (2x8GB) DDR4 PC4-24000C16
Samsung 500GB 860 EVO SSD
Kolink KL-1000M 1000W 80 Plus Bronze Modular Power Supply
Bitfenix Nova Midi Tower Case

From day one I was experiencing the system just stopping like I had a power cut and only pulling the plug for 10 seconds would allow me to reboot

few back and fore with OcuK and we replaced the Video Card and TBH that seemed to sort it, until about 4 months later I went to play Sniper Elite 4 and it just kept happening SE 5 played with no issues though and by avoiding that game I had no more issues, it did happen but very very infrequently
l
Yesterday though the PC shut down multiple times, took the side off to check for heat related dust, very little, but noticed fans not spinning (I know its the AMD zero RPM) turned them on and all seemed ok for the rest of the day so this morning I put the side back on and within an hour it started shutting down again

took side off fans not spinning turned fans back on and so far about 5 hours with no issue

So im thinking one of three things

The video card is possibly the issue, possibly through overheating
The power supply is the issue TBH not seen the best of reviews about Kolink
Possinly one of the cables but I dunno Ocuk were pretty thourough when they had it back

For some reason taking the side off the case ,,,,, yeah I dunno it seems odd but is the case on causing the mobo to short ...is that insane

Had thoughts of changing card to Nvidia anywa as I kind of want to play Alan Wake 2 so that may help me narrow it down

Anyway any suggestions I looked at the skill thats been put into wiring the Power Supply up and there is no way I will do a job as neat as that sp I am hoping thats not the most likley
 
Hey Tetras thanks forthe reply

Yeah I just turned off the Zero RPM and the fans on teh GFX started running )all the rest are on by default) and it seems ok, not sure why they had defaulted back to off tbh, at the mo it seems stable so my thought is get the side back on the case and see what happens with the side on and fans running

Se4 Not sure TBH but pretty sure back when I first tried I had the fans on .... I may give its a try but honestly I'm worried all these hard shut downs are going to stuff the drive.
 
I kind of doubt overheating TBH dust was a longish shot as this is happening when im just browsing and nothing else going on, but yeah not seen good things about the PSU think covid may have had a bit to do with it and shortage of parts, I guess PSU is the sensible place to start.
 
Quick update, I had just put the side back on the case and within 10 minutes (about 2 mins after last post) it has shut down, going to leave the side off for the next 24 hours then try putting it back on,

Been running for 5 hours with side off but all fans are spinning and there is no dust or blockages I can see its a really clean case this is just weird

BTW the hard shutdown does cause Zero RPM to switch itself back on

EDIT> So did a little reading and found myself reading amazon reviews and teh majority of then have my issue worked for a good while then hard shutdowns galore will look into a new PSu

More I read more its pointing toward the PSU, Been a real while since I did any self build, Long enough for the PSU to change from the box with teh multitude ofcables to a box with pluggable cables and TBH that makes changing much easier, Im thinking I can just pull all the cables and then switch boxes and plug them all back in and that will save messing with all that tidy cable management that OcUK did

any recomendations on a decent ish PSU that will suit my spec and not break my bank ,,, no more than say £200?

My basket at OcUK:

Total: £447.97 (includes delivery: £7.99)​

Review of MSI here and Seasonic here.


Just to be clear, you mean using the new cables, right? You can't re-use kolink cables with a different brand (and sometimes not even if they're the same brand)
No I did mean that thanks for that bit of info still so long as I do it a cable at a time I figure should be ok, last time I did any decent build on a PC was maybe 10 years

Basically need a psu that has these connections which im assuming is just pretty standard



I do seem to have a 4 pin miolex plug for something on mine thats not got an option on the Seasonic one and I cannot seem to figure out where thats going on my setup might be the Bluray player.

They're standard on the device end, e.g. graphics card power connectors, but they're not standard on the PSU end. If you use modular cables with a different pinout then best case: PSU doesn't turn on, worst case: everything connected to the PSU is fried.

Followed that 4 pin molex and it connects into the 24 pin mobo one at the mobo end, not sure why tbh and everything seems to be running just fine without it and not a lot of info online so aif anyone has any ideas.

My setup is basic I have the Mobo a single SATA, the CPU, the GFX and any fans that may require power so cable setup is basic, im thinking that 4 pin into the 24 pin is a Kolink thing and im nit having a lot of google luck finding out why

EDIT> I do remember back in early 2000 we used to have 20 pin and a 4 pin molex for the mobo but this one is making the 24pin a 28 pin ?

Do you have any power cables that would get pushed in or moved in any way when the case side is on? GPU cables?

From what you are posting it does sound like you are only getting the problem with the side on, it seems more than a coincidence although could still possibly be a red herring.

I'm wondering if when you put the side on it pushes on a cable with enough pressure to give it a bad connection.

I was starting to hope that then it shut down anyway had about 10 today so just going to bite the bullet and grab a PSU And eliminate that
 
Bought in 2020 so warranty was up just 2 months ago, the PSU that Tetras has suggested look great I am just trying to figure out what this extra 4 pin molex is doing, on a beige build I would have said CPU but with it unplugged everything seems to be working fine. I cant figure what its actually for and why I need it.
 
Not sure what you're referring to. You're correct that the 24 pin splits into 20 and 4 for compatibility with older motherboards, but I've not seen a motherboard connector with 28 pins. It could be something that starts the PSU if it is operating a secondary PSU (e.g. when mining), but that's just a moonshot guess.

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

Bit the bullet and ordered the Seasonic

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.

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

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.

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 :) .

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:)
