The PSU is the one responsible for distributing power to all your components.
The power supply that you should use is robust so that your other PC components will not face power shortage and cause the system to crash or reboot.
An 850W PSU is on the higher side since most budget desktop pcs are made using 550W PSUs. If you are going to install high power components like a powerful graphics card and cpu then you certainly need a high power psu in the range of 850W.
The high end nvidia gpus like RTX 3090, 2080 and those from amd like RX6800 are power hungry gpus that will need a lot of power when under heavy load processing gaming graphics or other 3d applications.
Consider the following build:
- i9-11900K - 125W
- RTX 3080Ti/3090 - 350W
- ATX motherboard
- 32GB RAM (16gx2)
- 1TB SSD
Such a system would easily need around 650W. If you overclock, the power requirement would go even up. The best option for such a high end build would be an 850W PSU that can provide sufficient power even under overclocking.
Moreover if you are looking forward to setting up a multi-gpu system like SLI then also the power requirements of the PC shall go up. Though with a 850w psu you can setup a dual gpu setup with an rtx 3060Ti only and no higher. If you plan to use a RTX 3080 or 3090 dual gpu setup then you would need more than 900 watts of power from your cpu.
Other kinds of builds needing higher power supply include those using Ryzen Threadripper 3990X cpus as those are some of the most power hungry cpus.
Corsair HX850i PSU
There are some other components that could draw more power depending on your specific build. For example if you plan to install lots of RGB led strips or custom water cooling loops, they shall need more power compared to ordinary builds.
It should be kept in mind that the system does not draw in that much of power all the time, but only under heavy load or peak conditions, and the psu should be able to provide adequate power under all load conditions.
Higher power psu puts less strain on the internal components of the psu thereby increasing its life-span. Lower power psus will often suffice but will stress their components more to draw higher power when necessary.
A high power PSU also ensures that it will be able to power more components in future that you might be adding or upgrading to, making it future proof.
With that, let's take a look at the top 850W Modular PSUs that will reliably and efficiently power up your PC.

From the first glance, you'd know that the ROG Thor 850W PSU towers are above the rest in terms of aesthetics. With its real-time power draw monitoring using OLED Power Display and its Aura Sync ARGB illumination, they make the exterior design of the Thor 850W premium. The ARGB lighting is highly customizable with Asus' accompanying program, Aura Sync.
The interior is just as strong as the exterior, if not more. They enhanced the heatsink configuration so that the speed of the fan will not ramp up and make noise. The fan that the Thor 850W uses is Asus' own wing-blade fan, which utilizes the thermal sensors of the PSU for smart speed adjusting.
It also features Japanese capacitors, which makes power conversion more reliable. As a testament to that, the DC output, when tested, provided a peak value of around 20mV ripple noise on the 12V rail and about 5 mV lower for the lower voltage rails.
The cherry on top for this PSU is its 10-year warranty, meaning Asus ROG is confident that they can maintain this high-level performance for a long time without malfunctioning.
Elite exterior aesthetic, strong build quality, almost non-existent noise levels on moderate loads, excellent and efficient power performance, and innovations that advance the competition, you could not ask any more from a PSU with Asus ROG's entry to the market.
The only drawback for this unit is its price, with it being the most expensive PSU on this list. But Asus' flagship brand ROG is not marketed for budget enthusiasts anyway. Its goal is to provide high-end and premium products, like the Thor 850W.

The Corsair RM850x is a mid-range PSU and gives tight voltage control for each component. With an 80+ Gold rating, it is expected to have around 90% efficiency and maybe even more. This is made possible by its use of 100% Japanese Capacitors Design.
It also implements Corsair's special Zero RPM Fan Mode, where the fan stops operating on low to medium loads. The fan will start when it detects higher heat dissipation.
Corsair's approach with this product is to keep it simple and focus on optimizing the factors where a PSU should stand out. It managed to find a balance of good power performance, high build quality, low noise levels, and a decent price tag.
In other words, the Corsair RM850x 850W 80+ Gold Certified exhibits all the qualifications of a good PSU.
Conclusion
Choosing a Power Supply Unit is not as complicated as the PC building community makes it out to be. Once you know the power requirement of your PC, you just have to be aware of how the efficiency calculation works. Make sure you leave an allowance for future upgrades and maximizing the ability of your whole set-up.
Do not get me wrong, it is not complicated but it is definitely crucial. A malfunctioning PSU is not only a danger to your PC components but also to your own safety. By investing in a good PSU, you are essentially investing in every component of your PC. You're extending their life expectancy by preventing them from being vulnerable to power surges from a defective PSU.
They might not be the most visually appealing component for your PC, however, it still carries the huge burden of how your PC operates, so it would be in your best interest to make an informed decision about the PSU that you'll be trusting your components with.

What is the average lifespan of a PSU? ›
How Long Does a PSU Last? Under normal intended use, a PSU should last a long time—at least five years, possibly up to 10 years if you're lucky. But if you start putting the power supply under high loads over long periods, it can be overstressed.
What can damage a power supply? ›Environmental causes
Moisture will corrode the electronics and eventually lead to failures. Other failure modes from the user environment include surges and transients that are well above the ratings and many IEC standards, which usually damage the semiconductor components in the front end of the power supply.
There are three major kinds of power supplies: unregulated (also called brute force), linear regulated, and switching. The fourth type of power supply circuit called the ripple-regulated, is a hybrid between the “brute force” and “switching” designs, and merits a subsection to itself.
Is it bad to buy too big of a PSU? ›We recommend leaving at least 10% to 20% headroom between what you need and the power supply's maximum rating. There is no truth to the myth that a large wattage power supply will force too much power into your devices causing overheating and burnout. The power supply will only provide the needed wattage.
How big of a PSU do you really need? ›A modern power supply must output at least 18A (amps) on the +12V rail(s) for a mainstream up-to-date computer, more than 24A for a system with a single enthusiast-class graphics card, and no less than 34A when it comes to a high-end SLI/CrossFire system.
Is PSU better at top or bottom? ›It is recommended to mount the power supply with its ventilation top cover facing DOWNWARD. The fan in the power supply will take in the warm air inside the computer case, and the power supply will exhaust the air through the back.
How do I know if my PSU is too low? ›Random program crashes, system freezes and the Blue Screen of Death are all symptoms of a computer that's not getting enough power. Like with graphical degrades, system instability symptoms often follow adding new hardware or upgrading existing components.
How do you test if a PSU is dying? ›Turn off any power switch on the PSU and plug the unit back into a working outlet. Turn on the unit's power switch. If nothing happens, the PSU is completely dead and needs replaced. If the fan turns, it's receiving some power.
How do I know if PSU is failing? ›During the startup or use of your PC, if it shuts down, PSU may be dead. If PC shutdown happens during the moments of high stress, for example, gaming or video encoding, you should be extremely vigilant. This occurs since the power supply cannot meet the demands of the computer.
