Both cases made a point that they weren't using ATX 3.1 PSUs too. Though Roman was using a cable from an ATX 3.0 that combined what looked to be 2x8 pins into the 12 pin all of those wires should be running parallel off the 12v rail so that should rule out an issue PSU side, especially if it were a bad terminal on the PSU. The issue has to be the cable since both ends terminate to a single point and the 12 pin is only splitting up the current into 6 paths. If not then it's time to look inside the 12 pin socket on the FE and see how they're terminated. This might be Cablemod right angle adaptor 2.0. High resistance joints are a thing, I've seen terminal blocks blown off because of a bad lug. There is definitely an issue here, there shouldn't be 22A on one parallel lead and 2A on another but these guys are asking the wrong questions. I'm not an expert in electronics, I'm just a rewinder/fitter (motors, armatures, generators,/alternators, transformers etc) but I know enough to know what I'm looking at. I've seen electrical engineers comment the same things to these videos and threads but it seems to fall on deaf ears. They just want to make videos. I'm sure Gamer's Nexus will be next with an hour long video that doesn't actually answer anything but will spread enough misinformation that will rile the community up.

5080s seem quite abundant at the moment and pretty easily found of you search around. Hopefully that means 5090s appearing isn't far off.

So many of the few 5090s have fallen into the hands of dumb people. Of all the burnt cables so far they appear to be down to stupidity or could have at least been avoided. There are the ones using aftermarket cables. I'll forgive that, could have been me if Cablemod made them for my PSU but now I know to just avoid. The others are mixing cables from different brands and chaining extensions. These people shouldn't be building PCs yet somehow they get their hands on a 5090. Go figure.
Jonny Guru, Igor's Lab, SIs like Falcon in the US have all come out and said the cable is fine. They've admitted they don't like it as the limits are being pushed leaving little margin for error but they said in all their testing it is safe.
Despite all this the first thing I'll be doing when/if I get my hands on a 5090 will be setting the power limit to 70% just until there is a larger sample size and someone can get to the bottom of this.

Yeah as usual people are trying to make headlines, so I imagine a lot of these are going to be caused by stupid people, with the odd genuine burnout (can happen to anything) that said stupid people will desperately try to justify themselves with. Lets face it, a fair amount of the people who have them would be in the "more money than sense" demographic and picked them up from scalpers, one guy on Whirlpool has been telling people he paid $7k for one "because he can".
I've only got a 5080 and I'm still being a little cautious first up, putting the PC to sleep all the time and keeping the side off to double check the power. I seriously doubt I'll have an issue but I'll run it like that for a couple of weeks just in case.

I haven't seen any with uniform melting yet so it has always been to do with unbalanced loads for whatever reason (manufacturing defect or stupidity). If you want to put your mind at ease then just run furmark for 10 or so minutes then physically handle and inspect the 12v cable and see if any individual leads are hotter than the others. If your 12v cable is completely sheathed then just feel if it's generally warm and not scorching.
I saw Jay has just had an 8 pin connected to a 3080 melt with similar burn pattern to the 2x6 ones. GPUs and PSUs have to follow standards but there has been nothing enforcing third party cable manufacturers to date and I think they've just been lucky until now. Now with the power limits being pushed a lot of shit cables are about to be found out.

PLE have closed their Moorabbin store when I finally had a good experience there. Now I don't have anywhere close to work if I need to grab something quickly. Keeping their Dandenong warehouse open but I doubt for long if they don't have a Melbourne retail store anymore. If they're pulling out of Vic then it's not surprising as it's saturated here with big chains and Scorptec and PCCG would be hard to go against alone before you include Centre Com and the rest.

Great response from Corsair. The TLDR is they are yet to see any melted cable that wasn't first badly damaged. They also recommend no extensions or adapters on any graphics card that draws 500w+
The clueless me would have combined old power cables with newer components. Luckily I read up about it (20 years ago) before attempting such a thing

I've always thought if there is no standard pin out then the manufacturers should at least key their plugs so they only work with their own, or at least only interchangable with PSUs on the same platform, Seasonic, CWT etc.

Is it just me that thinks it is common sense to not use old cables with new components without first knowing if it is safe to do so?
- Staff

It's definitely common sense, but unfortunately it doesn't look as common as we think and the plugs fit so idiots are going to try it.

The card comes with cables anyway doesn't it?
- Staff

They come with a splitter type adaptor cable that goes from 12v-2x6 into however many 8pin PCIe plugs it needs (you still have to supply your own 8 pins that came with your PSU) for if your PSU doesn't have native support. What Aris (Cybenetics) and Jonny Guru (Corsair) are recommending is that for any GPU that requires more than 500w then don't even use that included adaptor. Their recommendation is if you're spending that sort of money on a new graphics card then get a new PSU as well that is either ATX 3.1 or at least a later ATX 3.0 that has a 600w 12vhpwr cable so you're running only a single cable between PSU and graphics card.

Thanks man.
Just noticed that there's revisions to my current PSU (Corsair RM850x) as well it seems. Think may hold off for a while and do a proper upgrade in the future. Not sure I'll be able to get away with a simple CPU and GPU upgrade on my current rig.

Rumours of a decently sized MSI delivery arriving in Aus on the 18th checks out then. If that's the case don't be surprised to see your date pushed out by a day or two while they get the supplies in and ship them out. I don't think you have to worry about being cancelled either because it sounds like they would have notified you already. Some people are still waiting for their refunds but they've at least been informed that their order was cancelled. 5080s are flowing now if you know where to look, I reckon I could go find one right now if I wanted. It's just if you're waiting on a specific model it might be a longer wait. I think I could snag a Palit or Zotac 5090 in the next couple weeks but I too am just waiting to see what's going on with next week's delivery.
Yeah 5080s aren't too hard to track down, especially if you have a local store. Centrecom 4 different models at various stores for click and collect right now, including the PNY model that's at 4 stores.

Depends on what it is, it's generally fine, but the risk goes up as the power that goes over it goes up. With a $4k-$5k GPU, and even a $2k-$3k GPU needing up to 600W I'd definitely be real f*cking careful and wouldn't be relying on too much 3rd stuff to power it.

Lots of smaller stores off the beaten path that use a different distributor to the big stores so stock is always popping up with them. You pay a little more through small stores because they aren't buying the same quantity and don't have the same buying power but they also don't typically take orders unless they have stock or know it's coming as they can't afford to lose any meagre margin. I've found CPL surprising as I wouldn't call them big chain in Melbourne but they're taking pre-orders are what looks like most likely launch prices. I contacted them and asked if they're taking them with knowledge of any ETA or availability and they said no, just back ordering. So that's strange as they might fall into the same trap as Mwave. I found another small store interstate opening orders and dealing Palit (biggest clue they're probably using Leader as their supplier and not fighting the big stores for stock) and another that I was considering before ordering the MSI but after a few days with a few emails and no reply I might have to give up on that one. It's not like they need my sale anyway at the moment. I will persist.

NVIDIA GB202 GPU supply for RTX 5090 set to increase, retailer has 147 RTX 5080 Cards but not selling them separately - VideoCardz.com
Some retailers have cards but won’t sell them to you According to MEGAsizeGPU, a person with very good ties to NVIDIA board partners and responsible for many GeForce leaks in the past, there is a significant increase in GB202 GPU supply. At least one board partner has already received “tons of...

Everyone is suddenly an electrical expert and there are some pretty wild theories flying around. "Load balancing" is one I'm not sure I should laugh or cry at. Also saying Aris and Jonny Guru aren't impartial then going in to defend a Youtuber who not only benefits from clicks but is also the CEO of a company who financially gains by selling a product aimed at the paranoia about said cable.

Something to make the 5090 wait even more excruciating is I just ordered an AW3225QF (Alienware 4k 240hz OLED). On sale at JB for $1519 until tomorrow, was going to wait until I knew when the 5090 was coming but the sale might not overlap again when that happens. Had a couple VISA gift cards laying around that I used to buy some JB gift cards first so got it for $1319. Ultrawide has been fun but it's time to move up to the big leagues.
