Can be a more expensive option
The Corsair RM850x is a popular solution for powering the RTX 4090. It is a flexible and efficient power supply. In terms of the specifications, it is Gold 80 PLUS certified, which is an average but good specification to have because it still saves you money with efficiency, but without premium features found in higher models. As well as being a fully modular power supply, the cables are not permanently attached. This allows you to personalize it as well as keep the cable mess to a minimum. This is very helpful for those of you who don’t particularly like managing cables. Sadly, you will have to use the octopus connector that is included with most ATX 3.0 power supplies because this PSU does not have the new 12VHPWR connector. Read more on : best power supply for 4080
EVGA 750 B5
EVGA 750 B5, 80 Plus BRONZE 750W,
Capacity~ 750 W
Efficiency ~ 80+ Bronze
Modularity~ Fully-modular
Form factor~ Standard ATX
PROS
Reliable and good brand at an affordable price
It is possible to build a good, clean, and affordable building with modularity
CONS
Running costs may be higher with only Bronze efficiency
It may make sense to choose a lower-end power supply if you spent most of your money on the GPU. You still should choose something reliable, though, as the power supply plays an important role in the whole system. There will not be much headroom with just 850W, so EVGA is a great choice as a well-known brand with good quality products. So there is no harm in getting EVGA, however if you need more power then you will need something more. With a bronze power rating, it is inefficient, which means that you will be paying more for it to run. This is because inefficiency in the conversion will require it to run longer.

It lacks the 12.4-pin connector, but you can easily fix this with an adapter. The SuperNOVA offers incredible performance even in a compact space. With 80 PLUS Gold certification, Cybernetics Platinum certification (89-91%), and Cybernetics Standard++ certification (30-35 dB[A]) noise operation, it offers unparalleled performance.

Features to look out for when choosing a PSU for the RTX 4090
Wattage
If you want to get the most out of your RTX 4090, you’ll need more power than Nvidia’s recommendation of 850W.
Modularity
With a fully modular power supply, you can connect only what you need and keep the area neat and tidy. Semimodular power supplies are usually less expensive, so those on a smaller budget might consider them.
Efficiency
In general, an 80 PLUS-certified power supply will be more expensive to buy upfront, but you can save a lot of money in the long run, especially if you frequently use your RTX 4090.
ATX 3.0 12VHPWR
A new ATX connector has been introduced to keep up with the ever-increasing demands of PC gaming. As energy uncertainty grows, we might also want to consider the new 12VHPWR connector.
Do I need 12VHPWR adaptor for Best PSUs for the RTX 4090?
The new 12VHPWR connector (which takes up to 600W of power) caused problems – specifically melting the ATX 3.0 rail around the connector. We’re sure outlets didn’t mean it when they called the new NVIDIA RTX 4090 a monster.
In late October, NVIDIA told The Verge it is investigating the problem. However, it is important to note that this isn’t happening to everyone who purchased the new RTX 4090.
How to do it? We’ve heard that the cable needs to be positioned carefully and should not be bent. With the drama now behind us, Corsair has jumped at the chance to launch its own single cable for $19.99, which doesn’t require an adapter for 12+4 pins.
Final word Best PSUs for the RTX 4090
From this list, you will have the chance to pick a power supply that will fully support your RTX 4090 GPU. An impressive power supply. In terms of power supplies, some creature comforts are nice to have, such as modularity and fan silence modes, but they’re not all necessary. You can go without some of these features just to save a few dollars.
It’s important to keep in mind that safety and efficiency are the most important things, so you’ll be fine with a PSU that meets those requirements and your RTX 4090. The 4090 will only be as good as your payment history if you keep making your payments on the small loan you obtained.
