The 4090 has a TGP of 450 watts and recommendations call for an 850W power supply at minimum. The other 40-series cards are around the same size, so regardless of which you choose, you may end up needing to upgrade.Īnother issue facing Nvidia’s mammoth 40-series GPUs is power consumption. That’s massive, and some of the third-party cards look even bigger. It’s a triple-slot unit that takes up to 336mm (13.2 inches) of space lengthwise, and it’s a whopping 61mm (2.4 inches) in height. Of course, the apparent performance bump certainly comes with a couple of downsides in size and power consumption. Taking things further, in a blog post released yesterday, Nvidia said the new GPUs with Nvidia Reflex could hit 360 frames per second (fps) while playing the new Overwatch 2 at 1440p resolution. Upon its initial release, Nvidia claimed the RTX 40-series graphics cards were up to four times as fast as the previous-gen RTX 30-series cards.
