NVIDIA RTX 40 series thread

Anyone here had their 12vhpwr cable go kaput?

Nope, used the NVIDIA supplied adapter and the Corsair cable on a 4090 with zero issues (both fully seated and using a 1200w PSU).

I still think it's user error and my mind would only change if GamersNexus can get a fully seated adapter/cable to burn.
 
I don't think it's user error per say, I think it's bad tolerances and design that allows a much smaller margin of error resulting in more 'user error' cases. That being said, I don't think I would trust the adapters either. Just going to stick to a 90' Cablemod adapter + cablemod cable 12vhpwr -> 4x 8pin until Seasonic makes a Titanium ATX3.0 / PCIE5 PSU.

Adapters are even worse for user error IMO. You change from one 12VHPWR port to worry about (side of the GPU) to 2 ports (side of GPU and bottom of adapter).

I'd argue that the current dual 8-pins from the PSU -> single 12VHPWR cables are even better than native PCIE5 PSUs because those also have two 12VHPWR points of failure to worry about (side of GPU and back of PSU).

Touch wood nothing yet … have the Corsair one and now the cabelmod one … the way the question is asked is as if you have had issues ?

Nope - but still don't like the state of the 12vhpwr's connector as issues like this aren't fun when it's supposed to be the de facto connector going forward.
 
I've just gave into CUD and pulled trigger on 4090. Probably going to a Corsair Shift PSU or something with native 12VHPWR.
What corsair adapter do you refer to and do you have a link.
Does anyone know where I can buy the correct pins and plugs and maybe make my own cables for my 1000D.
Ps, MSI showed a yellow 12VHPWR(Pcworld) that shows when not seated fully even if locked in.

No issues my side. Been using the Corsair cable since day one, have unplugged it a few times and ALWAYS ensured I've plugged it in correctly again.

Asus is working on something interesting at the moment, maybe this will help drag their name out of the dirt :ROFLMAO:

ASUS Unveils Proprietary New GPU Power Connector

ASUS has announced a new proprietary GPU power connector which eliminates power plugs in favour of sourcing the power directly from the motherboard instead.

There seems to be some reddit posts indicating the power melting issue is still a thing for cables that have been plugged in for several months.
 
You know it's cold when your air cooled 4090 is idling under 20c with no fan on :ROFLMAO:

So what's a decent overclock for these cards? It seems like I got the revised Strix model with new mosfets/caps to reduce coilwhine (lol, if this is reduced coil whine). And the A1 die that should have less voltage.

Regardless, I can do 3030-3045 core and +1100Mhz memory. Sits around 42-45c under full load in Speedway.

No issues for me, using the stock asus 12v till my new cable arrives, only changing the cable to make it look neat though.

the factory one is nastyyyyy
 
Been using my 4090 on my new FI32U and the 4090 really comes alive at 4K, it's just magical.

Previously I had to use DLSS Quality at 1440p (960p internal) to keep the image stable.
At 4K even DLSS Performance (1080p internal) is more stable and very usable. With that, even poorly optimized stuff like Forspoken or Remnant 2 runs smoothly. And DLSS Frame Generation is still magic, I enable it in every game where it's supported and I just can't notice any difference.

Having a blast with games at the higher res, you really notice more with the extra space moving from 27" 1440p to 32" 2160p.


NVIDIA really hit it out of the park on the 4090, but even the 4080 16Gb is something I'd be happy with if that was all my budget allowed.
The rest of the lineup though...

What do y'all think about the RTX 4070?

Seems like the range is going to start at around R13,500 at Wootware for the Palit Dual RTX 4070. This is, coincidentally, the same price as the RX 6950 XT (they're next to each other when sorting products by price).

Hypothetically, if I had already had a giant power supply, I think I would go for the 6950 XT for better performance and extra VRAM, but if I was building a new system I would probably go with the 4070 for DLSS and frame generation.

Realistically, I'll be sticking with my RX 6800 XT until the Nvidia 50 series and AMD 8000 series are out in 2024/25.

I ended up going with the 4070. That 150 - 200 W saving is looking more and more tasty with eskom's kak. Less draw on my inverter during loadshedding.

It is the best value Nvidia GPU this generation and makes even more sense after the latest Eskom price hike
 
Been using a cablemod cable (not adapter) since I got my 4090, had no issues with it - and I'm not worried. I think its just the adapters.

I think 600w through a connector rated for 660w is borderline too, but that's why the power limit is 450w for most brands.
Think only the Asus and MSI are 480w and 500w. And to get to 600w requires overclocking which always has its risks.

I still haven't seen a tech reviewer deliberately burn a properly seated cable at manufacturer settings. Or even at overclocked settings.

Anyway, NVIDIA should still go back to 8 pins anyway. 3 or 4. The connector is more trouble than its worth.
 
450w is standard, most 4090s that aren't budget-tier are 600w. Select few are higher.

I’ve been following northridgefix for a while regarding 12hvpwr, they said a lot of the burnt connectors were seated correctly, I agree with their opinion that it’s a Nvidia fault regardless (poor design). Would be interesting to know if there are any confirmed cases in SA of the connector burning. I must admit the native 12hvpwr cable with ATX3 power supplies looks so clean though
