NVIDIA RTX 50 SERIES - Technical/General Discussion

I thought there wouldn't be much of a difference going from the 4090 to the 5090. But playing Expedition 33 I could see and feel the difference. Maybe because its an Unreal Engine 5 game which can push GPU's that bit more.

Zero issues with mine, I picked the GeForce RTX 5090 Windforce OC. Cost me about £1900 but I sold my 4090 for about £1200 to soften the blow.

Seasonic 12v-2x6 90' cable came in, Much cleaner now.

Afraid to even touch the cable!

There are a few games where the 4090 to 5090 difference is very noticeable. Star Wars: Outlaws and Monster Hunter Wilds fit that bill. I wouldn't be surprised if Clair Obscur also did.

A 5090 catches fire, Literally, Fault likely came from the DrMOS according to Igors Lab -

ZOTAC RTX 5090 Amp Extreme Infinity catches fire while gaming and it wasn’t the 12V2X6 adapter - A hypothetic root cause analysis | igor´sLAB

A particularly dramatic incident has caused a stir in the PC community: A ZOTAC GeForce RTX 5090 Amp Extreme Infinity was literally on fire for the new game during a gaming session with Battlefield 6…

Makes me slightly worried for my undervolted zotac card as I think they use the same boards across the solid and the amp extreme. :eek:

I've read a few comments from seemingly knowledgable people and they are pointing to an AIO leak causing this issue as it lines up well directly beneath the AIO as well as various scorch marks.

I tried to sell my 4090FE on the members marketplace and didn't even get one reply.

They are going for like £1500 on Ebay

Ebay's too dicey for high value GPU's imo, they side most of the time with the buyer even when its a scam. Sold my 4090 for quite a bit more elsewhere with a face to face meeting.

MM prices are often very much on the low end but the hard floor is driven by the fact that you can still get around £950 cash for not even a particularly fancy 4090 on the high street meaning that £1,000 really still is the floor for an in person sale with a little extra risk and potential for further involvement down the line.

How can that be, the game's incredibly easy on hardware. I had to downscale from above 4k to get it to max out a 5080. It's not exactly a demanding game

Cable melting doesn't always happen under full load. Remember we had melting 4090s at 450W, with the 5090 being able to pull up to 575-600W depending on the model.

Plus, even less-demanding games can max out a GPU if they're running with an uncapped framerate. There's a case doing the rounds on reddit where the cable apparently melted while playing an older Civilization title.

Actually, if they want to keep making cards with this kind of power draw, they really need to do something like that. Splitting the power between two connectors should dramatically reduce the risk.

Huh?
That Titan card requires 2 600W 12VHPWR connectors verus 1? So it now requires 6 8pin's versus 3! That's twice the power draw, as it's 2 600W 12VHPWR's, so it's certainly not splitting a single 600W 12VHPWR from 3 8pins to 6 8pins :cry:

It doesn't draw 1200W. If you go back to the previous video he did on the card, its default power limit is 450W and you can push a bit beyond that with overclocking. So yes, there are more cables, but there is less power going down each cable and over each connector.

A 5090 with two connectors would have no more than 300W over each connector and I doubt we'd have any cases of melted cables.

I know that? But it clearly requires 2 seperate 600W sources for a reason, maybe it's the spikes under certain loads, either way, the card isn't relevant, it's the cable my point relates to.

What I'm saying is, that cable, they've gone from a single 12VHPWR with 3 8pins at the other end, to now showing a double 12VHPWR with 6 8pins at the other end, both 12VHPWR's being capable of 600W EACH.
So this is clearly their future plans when cards need more than 600W, i.e. to simply double up on what we already have, thus double the fire risk - that's all i've tried to say 3 times now :cry:

If they made a single 12VHPWR at one end and 6 8 pins at the other, then it would split 600W more safely - but they didn't, so that's irrelevant with this cable as it has 2 12VHPWR's and 6 8pins!

But nobody's talking about cards that need more than 600W, at least not for home use? Besides, plenty of existing 8-pin adapters for 12VHPWR come with more 8-pins than they need. My 4090 came with 4, of which you only needed to connect 3.
