How we picked the best high-end PSU

Selecting the best high-end PSU involves careful consideration of several factors, such as power capacity, efficiency rating, and build quality. Power capacity should align with the gaming PC’s requirements, leaving room for future upgrades. A high-end PSU will typically have a power output of 750W or more, enough to support multi-GPU setups, high-performance processors, and a multitude of peripherals.

Another key determinant is the PSU’s quality of components and manufacturer construction. A PSU made with premium components ensures a longer lifespan, stable power output, and improved safety. We also consider the brand’s reputation and the PSU’s warranty period. Customer reviews and professional PSU reviews from trusted sources play a critical role in our selection process, ensuring we recommend only the best high-quality PSUs on the market.

Product Reviews

  • ATX v3.0 and PCIe 5.0 ready
  • Great transient response
  • Plenty of connectors
  • Pricey
  • Noise levels can increase under heavy loads
  • High inrush current with 115V

The MSI MEG Ai1000P PCIe 5 is a powerhouse designed to take on the challenges of the new generation GPUs. This fully modular unit flaunts an impressive 1000W maximum DC output, making it a heavy hitter in the realm of power supplies. Sporting an 80 PLUS Platinum and Cybenetics Platinum certification, it guarantees efficient power usage while keeping noise levels within the Cybenetics Standard++ range (30-35 dB[A]).

If you’re a high-end gamer or a professional in fields like 3D modeling or video editing, where the best graphics cards are a necessity, this PSU might be your new best friend. You won’t find yourself with a lack of connectors either – it comes loaded with 2 EPS, 6 PCIe, and even a 12VHPWR.

Sure, it’s a bit on the pricey side, and it may get a bit noisy under extremely stressful conditions, but we think the power and compatibility it offers make it worth your consideration, especially if you’re an RTX 4060 Ti enjoyer. Plus, the 10-year warranty isn’t a bad safety net to have. It’s a true workhorse of a PSU, designed for enthusiasts who aren’t afraid to push their rigs to the limit.

  • High value for money
  • Compliant with ATX 3.0 specs
  • Comes with a native 16-pin connector
  • Noisy under heavy load
  • Lacks Platinum efficiency rating
  • Limited additional features

The GIGABYTE GP-UD1000GM PG5 1000W offers an excellent value proposition to those who need substantial power without breaking the bank. This power supply unit, with a 1000W output, is designed to handle even the demanding loads of the RTX 4090-tier GPUs with ease.

If you’re a gamer or a graphics professional running the latest RTX 4000 series GPUs, this PSU is a stellar choice. Its native 16-pin connector and ATX 3.0 compliance mean it can power up the current generation of graphics cards with no hiccups.

Bear in mind, though, it might get a bit noisy when under heavy load compared to other options in the market. Still, for the price tag that is well under $200 MSRP for a 1000W PSU, this is a compromise many users are willing to make. This PSU strikes a balance between performance and cost, making it an attractive choice for a wide range of users.

  • Extremely high power output
  • Excellent efficiency rating
  • Fully modular design
  • High price tag
  • Fan noise at extreme loads
  • Overkill for most average users

The Corsair AX1600i, as the name implies, is a powerhouse with a whopping 1600W output. It truly stands out in the PSU market as a high-performance, high-capacity unit that’s built for the most demanding systems. With 80 Plus Titanium efficiency, it offers one of the highest power efficiency ratings available.

This PSU is perfect for users who run extremely powerful systems, such as high-end gaming rigs, professional workstations, or even servers. Its immense power output easily handles the most power-hungry components, including multiple GPUs, numerous hard drives, and high-performance CPUs.

However, the Corsair AX1600i comes with a hefty price tag, reflecting its superior capabilities and build quality. The fan may also become noticeable at extreme loads, but this is expected given its high power output.

  • High power output and efficiency
  • Low noise operation
  • Stunning aesthetics
  • Higher price compared to competitors
  • Requires a suitable case for full aesthetic display

The ASUS ROG Thor 1000W Platinum II EVA Edition is not just a power supply unit; it’s an aesthetic masterpiece that could be the centerpiece of your gaming rig. It’s even more appealing to the enthusiast crowd with its Evangelion-themed design, OLED display, and RGB lighting, which exudes a sense of premium quality and gaming flair.

This PSU is perfect for avid gamers or PC builders who not only want top-tier performance but also value aesthetic appeal. The Thor’s Lambda A++ noise rating and built-in 0db fan mode ensure silent operation, contributing to an immersive gaming experience. Furthermore, its modular design and ample set of power cables provide flexibility and convenience during installation.

That said, the ASUS ROG Thor 1000W Platinum II EVA Edition does command a higher price point compared to other 1000W PSUs in the market. It also arguably needs a case that can show off its unique aesthetics, which may require an additional investment.

Features and considerations for the best high-end PSU

When it comes to high-end PSUs, several features and considerations come into play. Firstly, the power efficiency rating is crucial. Units with a higher efficiency rating, such as 80 PLUS Gold, Platinum, or Titanium, provide more power from the mains to your system, with less being wasted as heat. This is vital in high-end systems that require a lot of power to run optimally.

There are also Bronze-level PSUs that are built more for efficiency and budgetary options. While these are still relatively good PSUs, they won’t be as good for beefier systems that leverage high-end graphics cards. Keep this in mind when looking out for the best power supply that fits your needs and budget.

Secondly, the PSU modularity is an absolute must to consider. Full or semi-modular PSUs are preferred as these allow you to use only the cables you need, reducing clutter and improving airflow in your PC case. A high-end PSU also needs to provide sufficient connectors for GPUs, CPUs, motherboards, and peripherals, offering versatility for a range of system configurations.


Which brand is best for PSU?

Corsair and MSI are the most known and reliable PSU brands, and ASUS and Gigabyte are also great PSU builders.

What PSU for RTX 4090?

The recommended amount is 850W, but you’ll be pretty tight there. It will work, but it’ll be better to have a 1000W or if you are thinking of a more demanding job, even a 1600W.

Our Verdict

In conclusion, selecting the best high-end PSU is a balance of power requirements, efficiency, quality, noise levels, and in some cases, aesthetic appeal. While all the PSUs we’ve reviewed here provide excellent power and efficiency, the right one for you largely depends on your specific needs and budget.

Whether it’s the state-of-the-art MSI MEG Ai1000P, the value for money Gigabyte GP-UD1000GM PG5, the high-power Corsair AX1600i, or the aesthetically appealing ASUS ROG Thor 1000W Platinum II EVA Edition, each PSU serves a different type of user.

Though it might depend ultimately on your budget and build, the overall best high-end PSU has to be the MSI MEG Ai1000P. This is a power supply built for almost any build and allows you a ton of connections and is PCIe 5.0 ready, proving its merit at the very top of this list.
