NVIDIA RTX 50 SERIES - (PRE)ORDER DISCUSSION **NO COMPETITOR HINTING**

I got a brand new RMX1000x delivered from Corsair a couple of weeks ago. Should what I need for an RTX5090 be in the box?
Depends on if you have the 2021 version or the ATX 3.1 newer version from 2024. Newer version comes with native cables.
 
We’re in total hypotheticals here, who knows how anyone will act… but…

If the 50 series GPU uses a H++ connector and you plug in a native 12 volt cable into a H+ PSU socket… if there is an issue they might turn around and say that you knowingly made and took a risk on a mismatch. On one hand, this would seem ridiculous because everyone is saying these cables are the same and everything should be compatible, but then look at this info from Coolermaster:



…?! Very difficult for anyone to navigate with confidence.

There’s a big Reddit thread here of loads of people trying to figure out what the deal is and who, if anyone, is being misleading.
Yeah, followed some of your chat re this and looked up the H++ cable. The Asus PSU quoted:
''The latest power specification updates have landed. ATX 3.0 ushers in tighter voltage and current regulation guidelines for next-gen hardware - and ROG Strix Aura Edition steps ahead of the curve by being fully compliant. A 16-pin PCIe cable ripe for piping up to 600W of power to PCIe Gen 5.0 graphics cards is bundled with the PSU, readying your build for the next-gen.''
Thats why I bought it, in November...

However, I'd quite like to get that H++ cable and change colours and get a right angled one, cable not attachment, as it will be neater, so have the 675w cable rating and still have direct connection from PSU to Graphics card....but that then means I would be using an 'aftermarket' one...
Confidence is certainly low, and clarity certainly clear as mud.
I'll have a read at that Reddit post later. Thanks for that.
 
I think the 5080 seems to have been a lot easier to get with frequent deliveries meanwhile not much for the 5090. It's pretty odd. That said maybe the demand is a tad lower since it's not worth upgrading to from most of the 40 series unless you OC.
 
You mean the Suprim Liquid OC… I’ll give your astral 2nd place

Suprim will happily melt your 12V HPWR cables though with no warning - whereas the Astral will warn you. Gives the Astral the crown, IMO, as it's the only card that will monitor each cable.

Of course this is only if there's an issue with the cable or connectors. We don't know how prevalent this will be yet as only 5 people worldwide have cards. The 4090 situation was blown way out of proportion - though as the influencers have pointed out, the 5090 leaves little saferoom by using the full 600W.

I upgraded my psu to the nzxt c1500 and it is the newer 3.1 standard it also came with 2 hpw cables, it should be fine for whenever my 5090 arrives, I was hoping we would get more info on stock eta today ...
 
Was speaking to my local computer store as they were due in 5080 and 5090 and they said there's been a massive rma on the chip on 5090 and mass bios issues.
I was thinking after watching Der8auer's video, if this IS as dangerous as he thinks it could be, how would Nvidia fix it... They can't risk these things causing a fire and burning someone's house down. So what are the options? A full recall and redesign (can't see Nvidia ever doing that. It would kill this launch stone dead, it's already half dead, and they care about money way too much), or maybe a VBIOS update to lower the power limit of the card and reduce the risk? Performance would take a small hit, but at least it wouldn't BBQ you and your family (probably).
 
A competitor store did 3 drops of those yesterday for £3k, so it's probably the buyers reselling

Just seen msi trio 5090 on ****** 4 left in stock, price £6k

Looks like one of those 5090 gaming trios has sold for £6089. There were 4, only 3 left now. Probably thought OCUK are selling them for £25k so they were getting a bargain

Just in case this has been missed - this isn't the only source, I've seen at least one other news where another engineer talked about electrical design of 4k and 5k series (focusing on 4090 and 5090) and the general consensus is that just to decrease the size of the 5090 FE board NVIDIA simplified current balance circuitry and got rid of a bunch of basic safeguards, which means VRM will pull high power (even whole 600W) just through one cable if it has the lowest resistance (for whatever reason, even just small manufacturing differences between wires). No wonder they can overheat and melt, and it has little to do with the plug or cables themselves, it's full blame on NVIDIA here! 3090 had very different electrical design with max 200W per pair of cables, 4090 had it simplified and could already end up with all power through one cable, 5090 has even worse design.

What's more, 5090 doesn't have any safeguards anymore to protect PCIe connector, so if something goes wrong on the card itself the whole power could be dumped back into the PCIe connector and fry the rest of the PC. This type of design in basic electrical school would be marked as F, it's really unsafe to use and bad! I don't believe any engineer at NVIDIA wanted to do it, it feels like they were under management pressure just to make smaller PCB as "Nothing will happen, who cares!".

In other words, it might be best to really just sit and wait instead of chasing a card that's an actual fire hazard by bad design.
