1,000W PSUs are recommended for overclocked RTX 3090 Ti models

Will Nvidia's next-gen GPUs be even more power hungry?

1,000W PSUs are recommended for overclocked RTX 3090 Ti models

High-end RTX 3090 Ti models reportedly have extremely high power requirements

Nvidia's Founders Edition RTX 3090 has a 750W PSU listed as part of the graphics card's recommended power specs, and rumour has it that their planned RTX 3090 Ti will have an even higher power requirements. 

Videocardz has reported that an "RTX 3090 Ti OC model" has recommended PSU requirement of 1,000W, suggesting that high-end RTX 3090 models will require a lot more power than their predecessors. Currently, ASUS recommends that ROG Strix RTX 3090 OC users have an 850W (or larger) power supply, making the jump to 1000W seem incredibly probable. There are barely any PSUs on the PC market that deliver maximum wattages of between 850W and 1000W, making the jump to 1,000W a logical choice. 

What remains to be seen is whether or not the performance offered by Nvidia's RTX 3090 Ti will be enough to justify such high power requirements. Will Nvidia's RTX 3090 Ti be as efficient as its predecessor, or has Nvidia pushed the power levels of its RTX 30 series silicon too far? 

Note that this 1,000W PSU recommendation likely assumes that RTX 3090 OC owners will be overclocking their CPU and graphics card. This is what ASUS says on their website for their RTX 3090 Strix OC to justify their 850W PSU recommendation. "Our wattage recommendation is based on a fully overclocked GPU and CPU system configuration."

Yeah as soon as I saw the Kingpin using two of those dumb Intel connectors I figured stuff was going to get stupid.

Ahh, technology. Dragging us 9 years backward.Quote

Actually no. For every single GPU generation you could hear "Nvidia locked the power of this cards." 3080 and lower cards exist and they are plenty for most people, and they have reasonable power consumption.

Flagships should always be balls to the wall, unlocked, unconstrained. It is good that we are getting full power of the latest flagship silicon.Quote

To be fair these cards are not meant for the 99.99% of users, They are meant for people looking to break world records on LN2 that need unrestricted power, For the majority, Stock and supply issues aside, Exists the 3060/70/80 which are all very efficient especially when you compare the performance plus total wattage to the last gen, Quite nice gains.

The Intel connector is also pretty smart, Linus did a video about the implementation around a year or so ago and the power savings it can give, If the PSU and motherboard have this standard too, Are actually fairly impressive.Quote

No, you are right. These cards are not meant for us mere mortals. However. Ampere is a crap node. If you think I am wrong then I really don't know what to tell you. Power use should go down, and clocks should go up. That is good technology. Fermi - Kepler - Maxwell - Pascal. All did exactly that. Pascal hit 2ghz easy. The fact these are on a lower process node and guzzle power and don't clock any higher is testament to that.

AMD's shrink was how a shrink should be. If Ampere wasn't so terrible they would have buried AMD. Imagine Ampere, but at 2.5ghz and beyond. That is what should have happened. Only instead we have storage heaters.

Again ask yourself this. Where is the Titan? I answered that at launch. There isn't one and there won't be one because Ampere is so bad that it would be an insult to release a card that chews down over 500w.

If you think these are good? wait until they go back to TSMC. That is my point. You'll see.

Nothing has improved since they "unlocked the power". Nothing. At all. You could still easily overclock a 1080ti to 2ghz and more on water. Power was not preventing anything at all, apart from RMA. That is why they did that, not to stop you overclocking or having fun. In fact, from the moment they locked the power on cards? that was when the automatic overclocks started. AKA "Boost frequency" because that is basically what it is, automatic overclocking. You could push further, and you could easily reach a safe limit where your card would not go any faster and crash - because of power and heat. Nothing more. It was literally done to stop people cooking their cards and returning them.

I can unlock the voltage on my 2080Ti very easily. The problem is firstly it will void my warranty, but secondly there is absolutely no point AT ALL. My card tops out around 2180mhz on water, and that is all it has to give. Unlocking the voltage would not do anything unless I wanted to put it under LN2, which is totally impractical. I want to game, not set benchmark records.

The reason they have "unlocked the power" on Ampere is because they had no choice. Like I said to Dice, as impressive as you may feel it is the power it uses is an absolute insult. However, it is also the reason they unlocked the power. Otherwise it would, in order to meet sensible power use levels, be slow and crap. Because it's a crap node.

I tell you what. Debate with me all you like. Fair play. However. You wait until they go back to TSMC. All of a sudden they will be bragging about how efficient their cards are.Quote

The fact AMD didn't only catch up in rasta but go past them says it all, the nvidia lineup while in demand and popular is not a good result they are as good an upgrade as fermi i.e poor, they will go back to tsmc cause if they don't AMD is going to stomp all over them.

I'll say it here now, nvidia might be eating dust by the end of the year they gave AMD an inch and while AMD didn't take full advantage they sure gained a lot of ground I've had 2600Mhz on my card some are able to push higher everyone is so worried about DLSS and DXR that AMD haven't been given a fair crack of the whip by most but the 6000 series is a beast for AMD.

But in the end the power usage of the cards while bad will go higher next gen on both sides so i'd actually expect it to get much worse, but Nvidias cards were in no means a good node shrink at all very far from it.Quote
