RTX 4090 Power Supply Requirements

With the amount of GPU's you own and test these days I would really recommend getting a testbench to make testing easier. I would go insane if I had to change GPU in my case several times for every new game tested.

I have to say as a education employee myself (I'm a school counselor), I am so happy to have seen your channel grow from the hundreds to now becoming what it is. You provide very good information and you break it down so people less technical can understand (like a great teacher would do). The kids must enjoy your class!

Gonna start building a nuclear reactor to support the 7090TI when it comes out

Hi Daniel. Thanks for the great video and making it very informative of how a factor like CPU overclocking for an example is one of the reasons has why manufactures list their recommended psus.

Your rational approach to hardware is so refreshing and reminds me a lot of Hardware Unboxed. Your channel really deserves to grow big.

Undervolting can be a form of overclocking, you're asking the card to do the same work with less voltage

According to Tom's the FE Model will pull up to 493W so depending on the 850W PSU and CPU and other components it could work or might need more.

A good quality 850W PSU should be just on the edge with some upper midrange/low highend restbuild with barely extra stuff to keep longevity

Well I did get a 1200 for future proofing but I never thought id need to use it all so soon, and for the case I needed a new one with better airflow either way so I went ahead and got myself a Fractal Torrent.

I think founders edition and non factory OC AIBs can probably handle 850w in most rigs. I'm sure anything trying to get more juice out of it will clearly need more power.

The newer Asus Thor is gen 5 ready. I’ll get the replacement cable from Corsair for my HX1200 when I get my 4090. Hopefully a Zotac if available. I’m currently running a FTW3 3090ti with a 5900x, ROG Dark Hero X570 in a case with 10 Corsair QL RGB fans, Capellix H150i LCD, x2 Samsung 980 Pros, x1 Team Group T-Force Delta Max and a Lian Li Stimmer Plus 24pin. I currently only use this PC for high resolution VR sim racing. Right now I have 13 different USB devices plugged in to that sucker. It’s a lot of stuff to power but I’m not too worried about it. I do some automated OCing for the gpu through GForce Experience but that’s about it. Eventually though, when there’s a bunch of next gen PSUs on the market I’ll pick one up. I imagine the 24 pin won’t be around much longer.

I remember when this channel had less than 2k subscribers and now you have almost as many subscribers as some of the other YT than have had theirs longer so keep it up

Even if you have enough wattage, you may not have enough 8 pin connectors for the GPU on the PSU. Also, if you OC both a 7950X and an ASUS Strix, you may need 350W +600W +system 50W you need at least 1000 watts with no spike protection. Just go with 1200 watts if you plan new CPUs and OC for both and be safe.

If I was going to buy a 40 series card, I would definitely want a PSU that supports ATX 3.0 / PCIe 5.0 natively with the 12vHPWR connector.

The reason they were made to handle 600W is because the 4090 being released isn't even the fully unlocked AD102. The 4090 is only at 16384 shaders and 512 TMUs, and 512 Tensor Cores. The fully unlocked version has 18432 shaders and 576 TMUs, and 568 tensor cores (The 4090 Ti could have numbers close to this and that might be the one that draws 600W and higher - the last 10% of performance is where power goes way overboard). By not fully unlocking AD102 they were able to lower the power requirements.

Hi Daniel! Do you plan or going with a FE 4090 or will you be looking at the AIB Cards for your review purposes.?

i have the msi a1000g pcie5 psu coming in monday. they were backordered and scalped a bit but newegg got some stock in idk about now. also the GF3 Thermaltake you can get your hands on but i dont think its shipping until october 17th unless you want to pay scalpers. but you can find em today!

The real problem for me is horizontal mounting..... the card itself is tall and the adapter will go on top of that, but the adapter is way too rigid according to some videos..... and bending them too much could be disastrous for the adapter, thus conflicting with the glass panel in most cases. or so it seems to me.

I have an ATX 3.0/PCIE 5 connector PSU in my system right now. You can get them from a couple companies. I have an MSI MPG A850G PCIE5. They have higher wattage versions too. There's also the new Thermaltake Toughpower GF3 PSUs which are often in stock.

Igor also said in his video, that 4000 series is much more efficient and doesn’t have the huge spikes as the 3090/ti :) they should be running much more stable!
