I'm still confused about power cables and what exactly I would need. My current GPU is a Vetroo GV 1000 which is ATX 3.0 but in a 12+4 config not the newer 6+2. Would I still be able to use it?

I sent Vetroo an email and they said newer cables won't be available until at least April.

You just need a 4x8 pin female to 12+4 pin male adapter. It adapts your PSU's four graphic card cables to the newer 12+4 pin connector.

I used one with my older Evga Supernova 1000w and a 4090 Strix oc and it worked fine. No need to buy a new PSU.

Wouldn't I want to use the 16pin ATX 3.0 port on my PSU?
 
Will have to see but when DIY perks use regular heatpipe and unrestricted fans (a bit like a cpu tower) to cool gpu it does a great job-noise, at least in the past wattage:

Today expensive vapor chamber would be even better I suppose, I think he still do something similar with modern GPU in its built and it work quite well.

Any thoughts on Founders Edition v. third-party? I don't really really need the smaller form factor but I feel like it would make case a little easier to work inside, route cables, ect. Anyone have their eye on a specific version of 5090?
Click to expand...
I was originally figuring I'd get a Founders Edition this generation, but while it seems like a cool design, I'm thinking those fans are going to have to be working overtime to keep it cool. I'm thinking a full sized card might be the way to go, like my current Gigabyte 4090. The FE seems small and probably light enough that it probably wouldn't need anything to prevent sag. My current Gigabyte has a nice anti-sag bracket, and from pictures of the Gigabyte 5090s, it looks like Gigabyte will use the same system for the new cards. I've got tons of room in my case, so size really doesn't matter.

It seems like all the AIBs (or at least some of them) are making a big step forward in design/cooling with the 5090 "top" variants, to the point of offering new branding lineups. For instance, Asus ROG's "Astral 5090" - https://rog.asus.com/graphics-cards/graphics-cards/rog-astral/rog-astral-rtx5090-32g-gaming/ which is a 4-fan design; there's also a Astral LC version that is an AIO water block version. MSI has the "Vanguard 5090" - https://www.msi.com/Graphics-Card/GeForce-RTX-5090-32G-VANGUARD-SOC-LAUNCH-EDITION , Gigabyte AORUS's "Master" edition as well as liquid cooled versions, - https://www.gigabyte.com/Graphics-Card/GV-N5090AORUS-M-32GD#kf - among a few others. Of those I've seeen so far from major brand 5090s with air cooled high end variants, it seems that Asus designs have the most new features (as well as some extra connections, such as 2x HDMI 2.1b ports where others have 1, and 3x DisplayPort 2.1a thankfully) and cooling upgrades over the previous designs, but we'll need to see a more granular comparison as they move towards launch. Of course, price, cooling, and aftermarket potential will also factor in, especially when comparing AIB vs FE to see which are worthwhile.

The new cable is just called "2x6" because it has 2 rows that are 6 pins each for power: 6 ground pins and 6 +12V pins. The pinout is literally the same as 12VHPWR, which is why I said you can still use the same cable on the new cards. Both the new and old cable are "12+4."

It's a thing of beauty. I imagine that they used AI to get the PCB this packed.

Thanks, very confusing. So I can use the 12v cable that came with my PS. That's what I figured.

I assume there would be no advantage to using an atx 3.1 cable with an atx 3.0 PS?

Very, very confusing. I thought I had everything covered. Had I known this last year I would have bought an atx 3.1 ready PS.

Wondering if I should just install the brand new EVGA 1300 GT I have sitting here.

If your PSU is remotely new there's no need to even buy a 3.0 one. I bought a cablemod cable for my several year old Seasonic 1KW PSU and have had 0 problems.

No, there is no advantage. You can safely use an ATX 3.0 PSU with a 5090. I'm using an ATX 2.31 power supply with my 4090 right now and will still be using it if I get a 5090.

When I purchased the Vetroo GV1000 I didn't know if I'd be getting the EVGA 1300 GT (minimal cost from sending back a broken 1200W unit I had). When it arrived I had already put in the Vetroo. Now I have a brand new PS sitting here and I don't know what to do with it, was planning on selling it. I'm sure it's a better PS than the Vetroo, and it's 1300W which might be good to have with the 5090 at this point rather than a 1000W one.

I’ve bought the top tier card from Nvidia each generation, starting with the Riva 128. Getting my hands on a 4090 FE was one of the most difficult purchases I’ve ever made. BestBuy Canada and Nvidia itself were the only places you could purchase an FE at retail cost. For a good ten months after release, BestBuy would sell out within minutes.

I suspect that getting a 5090 FE will be extremely difficult.
 
I'm going to need an Asus Tuf Gaming 5090 I guess to drive two HDMI 2.1 displays w/VRR. That sucks- I really don't want to go ASUS because of their crappy RMA stuff, but I don't have much of a choice. You'd think two port HDMI cards would be more popular now, what with so many quality OLEDs people use as monitors.

FWIW these are flawless for DP to HDMI @ 120Hz+HDR. Multiple RTX4090 in separate systems each connected to multiple LG OLED's all using these.

I just got the dongle yesterday, VRR doesn't work. I tried multiple cables (even an active fiberoptic one) and both displays. What happens if that even though the Nvidia control panel allows you to turn it on the displays aren't receiving VRR, I can understand why some reviews are mistaken. I even updated the dongle's firmware and after I couldn't even turn Gsync/VRR on.

It works well for everything except VRR. I'm going to return it.

Bizarre. Try disabling G-Sync. I assume you also first tested that cable by temporarily unplugging all other video cables except it and a single screen, and then try switching it to each different DP port. Windows 11 and its storing/recalling of HDMI device profiles when plugging/unplugging can also create weirdness and false positives; I've thought one of those cables was DOA until I switched to a different port, possibly even a different screen temporarily.

Finally there's a limit to how many 120Hz displays the GPU can seem to drive (or it's a Windows issue, or Nvidia driver issue rather than hardware limitation), because beyond two (2), things can start to get squirrely. I've managed to drive 3 x 4K@120Hz from a single 4090 but it took a lot of dicking around switching between ports and finding goldilocks settings, like reducing output color depth and/or output dynamic range on one of them. Since this is offtopic you're welcome to DM further.

I tried everything.

Press your LG Oled's settings cog on your remote and see if it says Gsync is off even though it's turned on in the Gsync settings on the Nvidia control panel.
 
Tap the green button on the remote a few times and check the overlay as well, you'll see when the refresh rate dynamically changes there. (I mean that for DPI not Wag)

The Far Cry benchmark was the one that turned me off.

With my 4090 I have quite a few games that struggle slightly in 4K at max settings - will the 5090 improve those games to justify the $2000 price tag.

For those games, I’m guessing not. So the purchase becomes one for future games rather than past games. This is a new space we’re in.
 
There is like 99% chance that 5090 will be very undervoltable with almost no real performance loss - even more so than 4090 already is.
To me 4090 already looks like Nvidia made these GPUs use this much power because it does give slight advantage in stability and with superior cooling solution it makes all other cards look kinda bad in comparison. Same and even more so with 5090.
I would not be too surprised if 5090 will have 98-99% performance at 100W less power.

Even just power limit reductions would probably result in close to full performance at a huge drop in power usage, just like the 4090, let alone undervolting.

How wrong you are. Alphacool already have FE blocks waiting for release day. And unlike EK, their blocks are not outlandishly expensive in comparison.
 
Just built the following rig.
CPU Threadripper 7970x
Motheboard Asrock trx50 ws
Ram Vcolor 64 gb x 4 6000 speed 256 gb kit from the QVL list on Asrock website.
Nvme Western Digital SN850X 2 tb
Power Supply Seasonic Prime TX-1600 Noctua Edition
Video Card EVGA 3090 FTW.

Which 5090 should I get now that EVGA is not an option? Is founders the way to go since its only 2 slot? Founders Edition might be hard to get since its Best Buy Only. Might try my luck at Micro Center on release day.
 
God damm i cant imagine what the price of some of these AIB cards are going to be. Here in Australia, the FE 5090 will be $4100 AU, im guessing the Astral LC will be like $5K AU!!!!

Far out!! Wtf happend to GPU pricing!

Prices?
What I cannot imagine is what TDP some of these AIB cards are going to be to justify the increased price 🫣
And card sizes... it might quickly not fit in to standard 4090 optimized case or be so big no other PCI-e card would be installable 😵

I guess water cooling is the only way forward in this case.
Or doing cooling like Nvidia did it versus how AIBs typically do it.

That Threadripper 7970x will very very severely limit the 5090 for gaming (it already cripples a 4090), but if you have such CPU maybe that's not a big priority for you? (I hope)
https://www.techspot.com/review/2770-amd-ryzen-threadripper-7980x-7970x/#google_vignette

I don't think the model matters much, Founders will be cheapest and smallest, probably loudest too. But other models will very likely win on thermals and noise.

Threadripper 3960x worked well enough with my 3090. Running virtual machines, edit videos and photos. AI models, Blender, fusion 3d and Maya are more important then gaming. I was thinking founders being 2 slots would be best if I wanted to get more then one eventually. Guess I will see what I can get from Microcenter. Should I be avoiding Asus given what I saw from Gamer's Nexus from Asus.
