A power supply is maybe not going to be the first product you pick for your new gaming PC build project, but it could be one of the most important. It’s the heart of your PC – it feeds every component you have in your machine, and if your PSU goes down, it can take everything else with it.
From the CPU up to your precious graphics card, everything in your PC benefits from a decent PSU. The good units last for several system builds, even. So, if you make a good investment, you won’t have to spend extra money the next time you perform an upgrade. The way new processors and graphics cards are chewing through more power with each generation, that’s a legitimate concern. This means that you should plan to buy a reliable PSU with enough connectors to cover any possible upgrades.
1 RM750x (2021)
The best power supply for an RTX 3080
The time has come for Corsair to make some changes to its popular RMx line of power supplies since the competition has gotten far tougher in this segment of the market. Indeed the task’s not easy since the existing RMx units only counted three years in production and delivered excellent performance. In most cases, when you try to improve something already good, many things can wrong, but thankfully this wasn’t the case for the new Corsair RMx range.
The new RM750x has a significant performance lead over its predecessor, although it loses average noise output to the older model’s dead silent operation. The only section that needs a slight improvement is the efficiency under high loads, which is the main reason for the average efficiency. Nonetheless, the efficiency under light loads is sky-high. With two EPS and four PCIe connectors in two cables, this PSU will be able to handle a powerful gaming system with enough oomph to cope with a GeForce RTX 3080.

2 Prime Titanium TX-1000
The best 1KW power supply
The Seasonic TX-1000 is a great power supply featuring top-notch build quality. Besides great soldering work, it also uses Japanese capacitors everywhere, including many polymer caps besides electrolytic ones and a fluid dynamic bearing fan.
Seasonic’s engineers did their best to offer sky-high efficiency under all load regions and silent operation, at the same time, along with increased reliability. Performance-wise, this PSU belongs to the top league since it achieves tight load regulation on all rails, it has terrific ripple suppression without using the annoying in-line caps, and its hold-up time is sky-high. On top of that, the 5VSB rail’s efficiency is high, and at light loads, the PSU achieves some of the highest efficiency readings we have seen so far. Another asset of the TX-1000 is that it has six PCIe connectors on dedicated cables. You won’t have a problem powering energy-hungry graphics cards where the use of a single cable with two PCIe connectors should be avoided.
