4 Best 1600W Power Supplies 2021

Who Needs A 1600W Power Supply?

1600W Power supplies may become necessary in the future as graphics cards are drawing more and more power with each generation. The RTX 40 series cards are expected to be powerful by a decent margin compared to the RTX 30 series, this means the RTX 40 series cards is most likely going to draw massive amounts of power.

Besides GPUs becoming power hungry, you may require 1600W power supplies if you’re running a multi-component setups such as servers and multi-GPUs.

But even a typical gaming system can benefit from a massive power supply, over-powered power supplies cannot hurt your system, and power supplies with higher wattages tend to use higher quality components, and longer warranties.

1600W power supplies are great for silence; most power supplies are designed to shut off the fan if the system isn’t consuming enough power, so a 1600W power supply is more likely to be in silent mode than a 850W unit.

5 Tips To Consider Before Purchasing A Power Supply

1. Don’t Assume Higher = More performance: Many assume that higher wattage power supplies are better for performance, this isn’t the case. You won’t need a 1600W Power supply unit for a system that only requires 600W.

2. Pay Attention To Efficiency Ratings: Higher efficiency power supplies use better components which results in the power supply generating less heat and consuming more energy.

3. Research The Brands: There are so many power supply brands out there, and not all of them produce great products. Reliable manufacturers are – Corsair, Seasonic, EVGA.

4. Know What Type Of PSU You Need: Do you need a modular or a non-modular power supply? Modular power supplies allow you to add and remove cables, none of them are soldered. Non-modular units come with all the necessary cables pre-attached, you cannot remove any of them.

5. Don’t mix and match cables: If your choice of power supply is fully modular, you’ll notice you can remove all the cables. While this is fine for cable management, you shouldn’t include cables that didn’t come with the PSU, this is why some power supplies fail and bring other components with them.

Capacity & Efficiency:

Before you purchase a power supply, make sure it has an 80% certificate. Most power supplies will have this nowadays, but just keep an eye out.
