Best PSU for RTX 4080 Reviews
We’ll start the list with a product from a well-known company. EVGA has always dished out quality products in the market, and they get a high rating from the community due to their quality, performance, and durability.
The EVGA SuperNOVA 1000 GT, 80 Plus Gold 1000W, has all the specs and features to power a high-end build where components run in extreme conditions. The 1000W capacity is more than enough to fulfill the power demands of a build featuring an RTX 4080 with an overclocked Ryzen or Intel CPU with headroom to spare.
The PSU comes with Japanese capacitors and is fully modular, so you will be using only the cables that are needed making for better cable management in your case. It is an 80-plus gold PSU, meaning your input will be 90% efficient. It also comes with a single +12V output, making it compatible with the latest GPUs and hardware. The optimal operating temperature of the PSU is 0-50c, and to keep things cool, it comes with a 135mm fluid dynamic bearing which will help keep the temps down. It also comes with the proprietary EVGA ECO Intelligent control system, which reduces the fan noise.
It comes with several protective systems such as OVP (Over Voltage Protection), UVP (Under Voltage Protection), OCP (Over Current Protection), OPP (Over Power Protection), SCP (Short Circuit Protection), and Dual OTP (Over Temperature Protection) making it the ideal PSU for running a PC which requires a large amount of power input. Moreover, it comes with a 10-year warranty, and customer support is just a plus, making investing in this PSU worthwhile.
Next, we got a PSU from another well-known brand, Corsair. The RMx product series by Corsair has a lot of positive reviews from the community, which is why they have made it to our list of the best PSUs for RTX 4080.
The Corsair RMx Series (2021), RM850x, 850 Watt, GOLD is a fully modular PSU coming with black-sleeved cables, so your high-end PC containing an RTX 4080 with an overclocked Ryzen or Intel Processor can be powered without any hiccups in the power delivery department. To keep things cool, the PSU comes with magnetic levitation cooling fans to keep things keep cool and running at an extreme level.
Since it’s a Gold-rated PSU, it has more than 90% running efficiency. Due to the ball bearings present in the cooling fan, the PSU runs cooler and also doesn’t make a lot of noise, making for very good acoustics in the PC case, although even if they did make a lot of noise, the headphones would cancel the sound out, but hey the less noisy, the better.
The PSU contains multiple EPS12V connectors making it compatible with the latest GPUs, even the upcoming RTX 4080, which is starting to become available to reviewers and hopefully will be seen on shop shelves. It even contains the 12 GPU power cable for the newer GPUs. Furthermore, the fan of the PSU comes with a Zero RPM mode ensuring silent operation when the PC is running in idle or non-OC mode. But when the hardware requires power, the fan starts up to keep the PC cool and quiet so it can keep running optimally.
The PSU also comes with Japanese capacitors, which can function at 105c, and an efficient DC-DC conversion helping the PC wake up quickly. The rails on board can draw 70.8A current at 12V and give out a max output of 849W.
In the aesthetics department, the PSU supports a large variety of Corsair accessories, such as individually sleeved cables, 12VO motherboard cables, and 12-pin micro-fit GPU cables, making it a versatile PSU that gets the job done and also adds to the aesthetic makeup of your PC build.
For our next product, I have got a PSU that is designed for PC enthusiasts who want a PSU that belongs to the premium category of products and comes with all the latest features they would need to fulfill the power requirements of a high-end PC that makes them belong to the top end of the community.
The Thermaltake Toughpower GF1 850W 80+ Gold has a 140 mm Hydraulic Bearing Fan that keeps things running cool and quiet. It is a fully modular PSU that comes with a very durable chassis that comes with low Profile flat cables in the color black. Originally this PSU was designed for running an SLI/Crossfire setup, but modern GPUs have become quite power-hungry. It has more than enough horsepower under the hood to power a modern-day GPU from the latest series, such as the 40 series.
The fan has an Anti-vibration Mounting system and concentrated compression fan blades for maximum airflow. The airflow is further enhanced by the Side ventilation Design of the chassis. The presence of high-quality Japanese capacitors ensures that your system gets the power input it requires when it is running in extreme conditions. The DC-to-DC design conversion ensures that your system gets stable and continuous voltage when running resource-intensive apps or games.
If we talk about the noise profile of the fan, it’s a hydraulic fan. It comes with a smart zero fan feature that lets the fan run in zero RPM mode when the system is running in idle mode, and when the PC is running in extreme or OC conditions, the fan doesn’t cross the 30-decibel mark making for quiet operation.
The PSU meets the highest voltage regulation demands as the standard set by Intel is 5% tolerance, and the PSU comes with 2% tolerance for voltage regulation making for very stable power delivery. The PSU can deliver 850.8W with an output current of 70.9A and 12V as the DC output making for a premium Power supply unit that will easily power a system running an RTX 4080.
When giving out PC component recommendations, the list feels incomplete without an entry from the ROG product lineup designed to cater to the enthusiast sector of the PC community, who won’t settle for anything but the best.
The ASUS ROG STRIX 1000W Gold PSU Power Supply comes with ROG heatsinks, double ball fan bearings, and an Axial tech fan design to keep things cool and running in optimal conditions. These components and features are there since ROG focuses on keeping the components cooler by maximizing airflow and heat dissipation to prolong the life of the components.
When the TDP of the PC is below 40%, the 0dB technology becomes effective for silent operation. The PSU is a fully modular PSU that comes with 24-pin, 6+2-pin PCI-e, and 8-pin CPU cables containing capacitors that will work to reduce any voltage ripple. Moreover, these cables will help you achieve a clean-looking PC as well. The 1000w capacity is more than capable of running a high-end system with an RTX 4080 and the top-end processors like the Ryzen 7950X or the Intel 13900K, which have got massive TDPs on their own, but the PSU has the juice to handle the whole system with RGB and AIOs running in.
If you’re going for a ROG build, the PSU will fully shine in that system as it already has the power and performance, but with a ROG build, it will sync up with the rest of the build as it comes with a magnetic logo and stickers to add to the aesthetic value of your PC build.
The efficiency of the PSU is 80+ gold, and it can output 996W at 83 A at 12V on the rails since it’s a premium PSU with built-in protection features such as the PP/OVP/UVP/SCP/OCP/OTP. All these features and designs combine to deliver a very robust, powerful, and good-looking PSU that looks good. The 10-year warranty included by Asus adds the icing on the cake and makes it the best PSU overall for RTX 4080. Investing in it would be wise, and it won’t disappoint you.
They say that save the best for last, and if you are still reading, I have an overkill listing of PSU that you can use to run a system that will be hosting an RTX 4080 and other high-end components only found on enthusiast-class PCs.
Be quiet! Straight Power 11 Platinum 1200W is an 80-plus Platinum power-rated PSU that can reach efficiency up to a staggering 93.9% making for less power consumption and cooler temps since not a lot of heat will be generated as even at max capacity, the system will not be able to max out the PSU’s power capacity.
The silent wings 3 fan comes with an advanced fluid dynamic bearing, and paired with a 6-pole fan motor, it is one of the most long-lasting PSU fans out there. With a funnel-shaped fan opening, the fan inlet facilitates better airflow to perform better.
The wiring inside the chassis is also done neatly, and there is no obstruction of airflow from the clutter of wires, further improving airflow and ultimately prolonging the life of the components inside. The Japanese capacitors are also cut, as the PSU comprises the best components. These capacitors can operate at 105c, further adding to the durability of the PSU.
Since it’s the best one on the list, the cables are fully modular, making for a clean and tidy look as the extra cables are hidden from sight, which also increases the airflow in your PC casing. The PSU comes with Multi GPU support, with 6 PCIe connectors, and handling a single GPU like an RTX 4080 is a walk in the park. It has all the protective features such as OCP, OVP, UVP, SCP, OTP, OPP, and SIP, making it one of the best PSUs that delivers stable power input to your PC build. The only downside is that it comes with a hefty price tag. If money isn’t a problem, I would suggest going for it as it will make it worthwhile with the features and performance.
Conclusion
Everything reviewed until now is some of the greatest and safest power supplies you could get for your monstrous PC build. I hand-picked each based on their pricing, components quality, features, and overall build quality and versatility. The power supply is one of the key components of a PC, and it is the most crucial one as it powers every other component and is also responsible for its protection. If you’ll use a cheap power supply with a high or even budget PC, then in times of voltage fluctuations - your PSU won’t be able to save your PC and itself; hence, you should never cheap out on this one.
The article has options for many different scenarios, so in case you have a limited budget for each component and do not wish to upgrade for a greater period. You can go for the Corsair RM850X power supply. The unit comes with all the required certifications and is made out of high-quality stuff to keep your PC safe and sound when a cheaper unit isn’t able to. However, if you have some more spare budget in the same capacity, going for the Thermaltake Toughpower GF1 850W unit wouldn’t hurt.
In some instances where you plan to upgrade quite early because of a lack of substantial funds right now - you can get your hands on either the ASUS ROG STRIX or EVGA SuperNOVA 1000GT GOLD-rated power supplies. Both have a capacity of 1000W and are made out of super high-quality components and reasonable prices. However, in one particular situation where budget isn’t an issue and your work is highly demanding and asks for a multiple GPU setup, then, oh boy, this beast is quiet! Straight Power 11 is the one to go for. This behemoth packs a capacity of 1200W that can handle multiple graphics cards and has a platinum-level efficiency rating, making it a top-of-the-line product.
