Check your cables - Was having some issues and investigated to find....

Thought I'd just post an update to this thread :)

Kudos to OcUK,

I have spoken to the support team regarding the RMA, as I know they are busy at the moment, and they are honouring a return on it.

just received the RMA number and shipping label to box it up and post it back.

The only thing they wont replace is the cable kit, as I cannot find the order number or remember if it came from OcUK in the first place, as mentioned to the chap on the phone, I don't think it did as stock was scarce as they'd just been released at the time I purchased them. So that is totally understandable :D I had no expectation of OcUK replacing that.

And yes I will be staying away from 3rd Party cable kits, no matter how reputable they are.

Will keep the thread updated on the process, and how it goes for those interested :)
 
Hey guys,

Happy to say I have just received the replacement PSU after dropping the faulty unit off for DPD to collect on the 17th December
Replacement was shipped yesterday and arrived today!

Couldn't wish for a better outcome, and even got Haribo!

Many thanks OcUK, and in particular Adam, not sure if you are on the forums or your username if are :)

Appreciate it!

The cable kit would be in your order history if you did get it from OCUK and they would be able see this, so you must have got it elsewhere.

Good result and a fast turnaround.

Ah mate, I'm well happy for you! I'm glad you got some luck, considering it's Christmas!
Welcome to the '3rd party cables can **** off!' gang ;) :D

Totally!

Not worth the risk,

All appears well with my rig now, have played a couple of game with the RTX 5090 and it seems to be all good.
Will give it a proper test when I get to spend some time in my study with it lol, if it goes up again I want to be around to see/smell it!

I can only assume the cable went up when I had left the PC idle at some point, as I never smelt it and that would have stunk for sure!

Yep!

Nope :)

Ah nice, I'm happy to hear that mate :)

If it goes up in smoke, it'll be the 12VHPWR, doing 12VHPWR things :cry:
Nasty, well fingers crossed for you, I hope you have some decent Xmas gaming :)

I can only agree 100% with this now. Hindsight is a wonderful thing :(
To be fair there are a lot of horror stories out there, this had been running for 10 months before having any issues.
Surprised to see it happen PSU end though!

I think this had issues for some time.

There were no signs of any issues prior to when I updated the NVIDIA drivers, before that all was running fine.
Was a very odd one, would certainly have expected to see issues before hand.

After the driver update I started to get black screens when loading into a game, Windows was fine, YouTube was all good, only when something put a real load onto the GPU the screen would go black.
Hence thinking it initially was a driver issue.

All sorted now and my GPU is fine thankfully.

You likely had the issue from day one as the cable insulation has been completely carbonised to ash on two cable. It seems the heat has entirely destroyed one sense cable too.

I think what has happened is the copper conductors have started to breakdown and become increasingly resistive to the point the heat transfer through the cable to the card has been so significant it’s caused instability.

People should monitor 12vHP cables temps closely.

As you say, there is a lot of damage there, for it to have occurred instantly.

One of those things where most people think it only happens to others.
 
It’s worth monitoring cable temps, especially now the card has likely seen some very high temps on its pins, which will have altered the resistance.

Ideally the cable should be little more than a few degrees over ambient and all 12 cables maintain similar temperatures.

I won't even plug the 12VHPWR into the PSU by itself, nevermind buying a GPU that requires one....:cry:

You might not have much choice going forward for a while if you want to continue with PC gaming :(

Its such a crap connector design. It really is.

Yes it's designed to take the current, its had a couple of revisions.

There's something not right with that connector, they've never got to the bottom of it, you don't see 8 pin PCI-E's burning up, I don't think we ever have with any regularity.

I think my 9070xt will do me for another 4-5 years, well it's going to do me for another 4-5 years let's put it that way. I was gonna skip AM5 but looking at the landscape, i'm going for the best I can while I can. There's only so much one can do though. Putting together a 2nd PC with old parts i'm going offline with for older games.

That it should come to this...been building my own PC's for nearly 30 years, I never thought when I started out with all the advances that were going to come that i'd end up doomsday prepping my PC, but here we are...

:(

Thats the crux of it, the 8 Pin connector was great!

With the way pricing is going, and rumours of further massive price increases across NVIDIA and ATI GPUs... I honestly think PC gaming is at a point where innovation has got to stop. Focus on getting the best out of what people have.
Its either that or switching to console gaming, but even they have hit prices where historically you could have bought a top of the range gaming PC.

I have an ASUS Rog Ally Xbox X handheld, and honestly I am shocked at how well it games, I wasn't expecting much from an integrated GPU, but its handling itself really well.

I don't know... PC Gaming cannot continue as it is. Its becoming a luxury that masses cannot afford.

I don’t think GPU prices are going to increase in any significant way, at least not desktop level.

The issue is 600 watts from 12 volts requires 50 amps! which is frankly an insane current requirement x2. A 50 amp load really calls for a pair of 6-7mm2 conductors, not the 6 pairs 1.2mm2 in 12vHP connector which can result in one or two pairs carrying 90% of the load.

To put this in perspective, an RTX 5090 has the same current requirements as 5 household sockets, all under maximum load… Or the same current as an entire house… while changing an EV at full tilt… and boiling a kettle… when using the microwave…
