Are the RTX 5080 and 5090 safe to use?

Do you keep a fire extinguisher handy when you use either of these?

I've been reading that these two might melt like expensive ice creams if you don't plug the cable in properly.

It will shut down, or fail to boot, though I doubt anyone is daft enough to pair such things.

If you want PhysX to work you'll need a compatible card such as 980ti, so take this into account with your power budget. PhysX doesn't work on 50 series.

I wouldn't use them at all... it's not worth the money.

All you'll get is a downgraded 4090 without PhysX support...

its simple folks.....the plug is garbage and without voltage regulation per rail (I.E. perwire run) its a unsafe standard.....its ironic the 8 pins its trying to replace had voltage regulation on each socket

until the standard is changed i would never run anything over 400 watts on the plug, do to uneven current draw and the cheap wire used

It's 16 gauge wire, it's fine and can easily take the power as long as its fully inserted.

Again, it's a bad connection, but melting / fire is user error.

Agreed but you can't get 40 series anymore, some places it was even sold out months before launch sadly.

For the last few months they've been clearing stock for the 30 and 40 series here. The stupid thing is they are still expensive. The 4080 is only slightly cheaper than a 5080. It just makes no sense to buy a new old card.

Been playing mine for 8-10 hours a day on the weekends and so far my room stays at 81 degrees and not 83 like my 3080ti did.

They are very safe to use. I've been benchmarking my 5090 to death since I got it at release. Every ♥♥♥♥♥♥♥ days in intense 3Dmark benchmarks or in games official benchmarks or Furmark. Nothing wrong to report, all fine and safe. Don't believe ♥♥♥♥ videos on the internet.

From what i can gather due to die space and all the extra stuff in the 5090 (more RT, dual encoding ect) 32bit CUDA took a hit and PhysX runs on 32bit CUDA so it's disabled at the driver level, 5090 still has 32bit CUDA but not enough to do whatever + PhysX I guess.

No solid evidence though beyond chatter.

I've only just got my 5090 but seems fine so far, I got the cheapest 5090 the MSI Ventus 3X for £1940.

Runs cool enough (I do have one of the best air flow cases) topping out at about 70c, power draw is about 450/470W at full tilt in normal raster games but goes up to 550/570W in a full RTX game like the new HL2 RTX demo.

Tested a bunch of games and so far no driver issues to speak of and it runs like a beast.

The dreaded power cable, ok so far, looks a lot better than having to use 4 of the old style, the wire after extended play is warm to the touch but not hot and the heat is spread even, should they have put 2 to split the load? Maybe but I can't see an issue if that's as warm as it gets.

Is it perfect, no
Is it a ripoff, sure
Is it the best, you dam right

P.S I got all the ROP's, lets goooo

Congrats on picking one up at msrp.

Was it a pre-order card?

Is inno3D any good? Would you buy one for 200€ less than the cheapest MSI?

#43

Monk Mar 25 @ 2:15am

They are fine, depends what that price sits at, but, if you don't have a reason to go for a specific model, I say go with the cheapest one you can find they are all the same chip and same power limit.

Yeah I want to the Nvidia launch event at SCAN and for turning up you could order any 5090 at MSRP, they only had 25 in stock and I was about 70 deep into the queue, they had about 100 5080's so loads went away happy with them at MSRP, well as happy as you can be at a steep price.
