1600W Power Supplies lie in the upper echelon of PSUs. They’re the beefiest power supplies you can fit into a PC. And for this very reason, they’re either used in multi-GPU or server setups that need all the power they can get and run reliably without getting any hiccups or jitters in power delivery and performance.

Power supplies are also the least replaced component in a system and even if you change up your GPU, motherboard, and CPU, it’s highly unlikely you’ll switch to another power supply. So, if you’re planning on swapping out components in the future, it’s best you go with a power supply that can last you more or less a decade.

Do I Need a 1600W Power Supply?

It all comes down to your use-case scenario, but there’s also a factor of future-proofing. As time moves on, it’s evident that GPUs–while becoming efficient, are also consuming more and more power. There will always be that AIB partner flagship GPU like the RTX 4090 that draws an immense 450W of power from the PSU. So, if you’re planning on upgrading or future-proofing your setup. You can’t go wrong, investing your money in a beefy 1600W PSU.

In addition, 1600W high-quality power supplies will last you for years, along with decade-long warranty plans. There’s also the efficiency aspect, with most 1600W PSUs being rated 80 Plus Platinum, ensuring you can run different PSU loads at maximum efficiency at all times.

Pros
  • GaN semiconductors

  • 80 Plus Titanium
  • Silent
  • 10-Year Warranty
Cons
  • Incredibly Expensive
  • ICUE software isn’t everyone’s favorite

The AX1600i is, without a doubt, the best power supply on the market. It’s rated at 80 Plus Titanium, which is the highest efficiency rating in the voluntary certification system. And surprisingly, it’s very quiet due to its high efficiency and semi-passive nature. And best of all, the power supply only takes up 200 mm of space due to the use of Gallium Nitride semiconductors. And as standard, it’s fully modular, making cable management a breeze.

Pros
  • Can easily handle RTX 4000 series GPUs
  • High-Quality Japanese Capacitors
  • Runs 24/7 with ease
Cons
  • Fairly massive
  • Expensive

The EVGA T2 is another 1600W power supply on the list. And the only reason it isn’t first place is that it’s a big chunkier–specifically, by 20 mm. Owing to its ludicrous 80 Plus Titanium rating, it’s perfect for your high-end gaming, server, or crypto-mining rigs that are supposed to run 24/7. Like the AX1600i, it uses high-quality Japanese capacitors, ensuring a long lifespan. With the larger size, you get a bunch load of SATA connectors too if you’re looking to run tons of cold storage.

Pros
  • Cheapest 1600W PSU
  • 80 Plus Gold
  • Silent Operation
Cons
  • The outlet plug can come off

If you’re looking for a gaming power supply that provides you solid reliability, a cheaper price point, and better value, then you can’t go wrong with the EVGA G2. But it’s only rated 80 Plus Gold, which is fine in this case, since you won’t need to keep it running for extended periods of time. This also brings down the price considerably, making it one of the more budget-friendly 1600W PSUs. You can easily run multi-GPU rigs without any issues popping up. And as standard, you get a 10-year warranty.

In Summary

Go big or go home. 1600W PSUs are perfect for high-end applications like multi-GPU setups, mining rigs, or workstations. You can max out your credit with the AX1600i or go for the slightly budget-friendly approach with the EVGA G2.
