Corsair RM750x

The Corsair RM750x tops our list for one simple reason: it’s the most well-rounded power supply on the market. On top of a 10 year warranty and an 80 Gold Plus efficiency rating, the Corsair has a fully modular cabling system. That means you only need to install the cables you need. Not having unused cables in your case is great for air-flow and for those who appreciate the value of good cable management.


EVGA 500 B1

When you’re trying to keep the price of your PC similar to that of a console, you don’t want to blow a lot of your budget on a power supply. That’s where more economical options like the EVGA 500 B1 come in handy. This PSU is essentialist without neglecting the needs of its audience. For less than $50 USD, you can expect 500 watts of power transmitted through several SATA cables and two PCIe slots. A three-year warranty is merely icing on the cake.


be quiet! Straight Power 10

Power supply fans seem to run the loudest, and unlike case fans, they aren’t quickly swappable. Fortunately the Straight Power 10 line up runs nice a quiet. Options range from 400w to 700w, and they’re SLI and Crossfire certified. They also have a modular design, letting you use only the cables you absolutely need to use. It’s also low-profile, freeing up even more space inside your computer tower.


Silverstone SFX Series SST-SX550

Power supplies can occupy a ton of space in your desktop tower, however time has allowed for the units to get smaller while the power they emit only expands in magnitude. The Silverstone SX550 is almost half the size of other power supplies, so that you can better facilitate cables and airflow inside your computer. This makes it notably ideal for micro ATX and mini-ITX builds, though you could slide it into a mid- or full-size tower as well if you deem it necessary.


Corsair AX1500i

This is an absolute monster of a power supply. This is for the serious builder who plans on powering multiple graphics cards, cooling systems, and perhaps a small village in rural North Dakota. It has the highest possible 80 Plus Titanium efficiency rating, and is fully modular so you only need to add the cables required by your build. If you have the money to go big, this is the power supply to get.
