Best 850w Power Supply 2023 (Top 10)

1) EVGA Super Nova 850 G5 High-End Power Supply

The EVGA SuperNova 850 G5 sits in the range of top-of-the-line power supplies from EVGA. As compared to the SuperNova 750 P2 power supply, this G5 model holds more wattage, a high-end 80 Plus Gold rating, and better thermal management under peak loads.

This is a fully modular power supply with high-end capacitors and a 135mm Fluid dynamic fan for super silent operation. There’s Eco Mode on this PSU that turns off the fan when there is no load.
This power supply is sufficient enough to power a gaming CPU like Core i9 9900K along with an RTX 3080 Ti GPU.

Not only RTX 3080, but you could also power an RTX 3090 with this power supply as well.
This high-end power supply costs a few more bucks as compared to the Corsair RM750x PSU on our list. By just paying $20 to $30 more, you get a high-wattage power supply that is well-built and has the same 10 years of warranty.

We’ve used a number of their graphics cards over the years, but we’ve yet to combine one of them with an EVGA power supply. Since this is the first time we were able to get ahold of a unit manufactured by them, we are unable to properly discuss their performance with past products. EVGA has had a run of high-performance releases together with SuperFlower.

That’s about it. That the SuperNova 850 G5 may not meet the requirements of high noise levels when being loaded (the likelihood being very slim), but it produces exceptionally sound rail stability as well. (In at least) PSU performance is one of the most important issues for any PSU (if not the most important). The 80 Plus Gold efficiency certification was not the highest possible, but it should easily cover all consumers out there and most efficiently offer a continuous output of 850W (990W peak). Although the SuperNOVA G5 line is also good in terms of design due to the exceptional grill, incorporating RGB lighting in the fan window by the knobs would be a welcome change.

5) EVGA SuperNova 850 P2

Although SuperNova P2 is the sole line of enterprise-class energies, geared toward power users, that isn’t to say that these systems aren’t intended for amateur users. The 850W P2 model is primarily appropriate for an IT suite or multiplayer online battle arena, built with two graphics cards. According to EVGA, its power supply is able to power up to two graphics processing units, as long as each one requires less than 300W.

So, in your country, This method can provide enough power to the RTX 3090 CPU, which derives 350 watts by itself, as well as a high-performance i9 or AMD Ryzen 9 processor overclocked. In addition to being rated Platinum, the P2 s primary focus is on a 12 V rail design that can deliver the system s maximum output on its own. Alongside the main rails, the minor ones, on the other hand, are slightly more developed than what we see in standard PSUs. However, they will still be suitable for a high-end system

The Final Word for the ITC SuperNova P2 is that the P2 is entirely modular, so we can simply use the cables which are required for the system based on cable management. This feature will raise the PSU-effectiveness buy-in, and important cable management is definitely a worthwhile investment. Add this to the active cooling mode that can be electronically controlled, and we have a working PSU that’s silent and fully efficient.

The SuperNova P2 line of PSUs is geared toward firecracker buyers who are wary of paying a little more money for excellent quality. In NVIDIA’s inner specifications, PC systems built with video cards (such as GeForce RTX 3090) made based on the 800W P2 were the recommended stimulus for the power supply. According to EVGA, power supply 850W P2 has sufficient strength to power up to two such card setups, although each pair requires less than 300W simultaneously. This is about enough to power the RTX 3090 that utilizes 350W at low power, and an overclocked i9 / Ryzen 9 processor.

6) Corsair RM850x

It provides di event features than other, run-of-the-mill 12V rails and is capable of supplying the maximum suburban railway s energy without assistance from other rails.
The minor rails, by comparison, are slightly weaker than those seen at other sites, but they will still be enough for a high-level system.

Corsair remains a key element in the PSU market, and the RMx stable shows that the firm still has a place in it. To sum up the overall experience, the RM850x is powerful, efficient, and sound enough to support an RTX 3090 as long as a Threadripper isn’t used. Corsair remains a solid player in the PSU market. Nevertheless, the RM850x is a powerful yet efficient 12-volt power supply that has the capability of delivering its full load through a single rail. Nevertheless, its minor PX rails deliver a combined 150 watts of power, which is overkill for modern systems today.
