Nvidia RTX 4090 graphics card power demands could make Thor weep

The Nvidia RTX 4090 graphics card is a high-end graphics card that features the new Turing architecture and supports Virtual Reality (VR), real-time ray tracing, and AI-assisted graphics for gaming. It features a fully enabled TU-104 GPU with 10 SMMs and a boost clock of 1.90 GHz. Nvidia’s new RTX series GPUs are not just for gaming. The new line of cards is designed to deliver real-time ray tracing and AI-assisted graphics rendering for everything from video editing to architecture and design.

Nvidia’s RTX 4090 graphics card may be a power-hungry beast, that’s a given, however, we have a tendency to weren’t expecting to ascertain a number of the figures third-party card makers are recommending for the electrical power of the ability to provide (PSU) necessary for this GPU. In some cases, we’re gazing at a recommendation of 1000W, associated one company has even pushed the raise to 1200W, no less, an unbelievable needed wattage not farewell ago.

Note:  This can be the wattage of the PSU, not the cardboard usage.

You will bear in mind that the official recommendation from Nvidia is an 850W PSU, and indeed, this can be the amount some third-party graphics card manufacturers are jutting to with a number of their RTX 4090 boards (even far away from entry-level versions). As Tom’s Hardware(opens in new tab) points out, that features MSI (with the RTX 4090 Suprim X), PNY (Verto Epic-X), wandflower (SG, ST), Inno3D (X3 OC iChill Black). These all have Associate in Nursing 850W requirements.

Then there are the graphics cards that are stipulating a 1000W PSU, which might be models from Asus (ROG bird genus OC), GB (Aorus Master), and Zotac (AMP Extreme, Trinity). And finally, there’s Palit which advises patrons of its GameRock OC version of the RTX 4090 to possess a 1200W power supply.

Analysis: Your new computer that doubles as an area heater

All of those are the top-end graphics cards from several makers (or higher-end models at least), as Tom’s points out, thus these are the thirstiest graphics cards around (when they are available out next week). The bottom RTX 4090 models do so follow Nvidia’s 850W recommendation, however with these supercharged third-party creations, that include fancy cooling and beefed-up clock speeds, it’s hardly any surprise that they’re power-guzzlers. 

And that we will see the logic in providing upped power needs in a very better-safe-than-sorry manner for the manufacturer. Significantly once these models are the graphics cards seem to be bought by the very enthusiastic overclocking computer enthusiast types, and the GPUs can likely be pushed very hard, maybe partnered with a power-hungry Intel CPU. (Alder Lake Core i9 offerings drive power usage hard, and bird Lake in ‘extreme performance’ mode is believed to travel even more with its electrical power slurping).

What card manufacturers are thinking is that they perhaps got to take into consideration what would possibly happen in this variety of eventualities wherever very power-hungry GPUs and CPUs are running in combo, once the system is flat-out running a requirement game or heavyweight app of some kind – and everything’s overclocked to boot. As Tom’s notes, Asus is so aforementioned that it’s presumptuous that 4090 house owners are overclocking their graphics card and processor, and as noted, that’s terribly seemingly when it involves this high-end territory.

On why Palit has pushed its needs to 1200W, the firm hasn’t shared its thinking therewith move, and it’s not very clear. The Palit GameRock OC will boost to 2610MHz, which is quicker than some RTX 4090s for sure, but 30MHz off the pace of the Asus ROG bird genus OC that sticks to a (mere, ahem) 1000W recommendation. We are able to solely guess an abundance of caution is being exercised here by Palit, or even there’s been a slip (or slip of the key) with the specification sheet here.

All of this rather underlines what a piece of ground power needs are getting with up-to-date PCs after you have graphics cards that actually that sort of toll on the PSU, to not mention flagship processors which will pull around 250W (Intel’s 12900K – whereas the incoming 13900K, as mentioned, is reported to hit a lot of like 350W therein performance mode).

To not mention that obtaining a PSU isn’t as straightforward as buying, say, AN 850W model. you would like to create positive you get a high-quality power supply, rated gold (at the terribly least), and one created by a sure whole (such as those picked go into our list of the simplest PSUs). Those manufacturers supply the merchandise that is tried and tested by the enthusiast community and offer the best expertise in terms of stability, which may be a must, particularly once you’re overclocking already high-performing hardware.

We’d continuously recommend factorization in some headroom once it involves the PSU recommendation anyway, and it seems that cardmakers are proactively doing this with their quicker RTX 4090s with all the whistles and bells. However enthusiast overclockers are cognizant of this anyway, and this territory is hardly the domain of the common consumer, of course.
