Best PC power supply 2019: top PSUs for your PC

Picking out the best PC power supply is the first thing you should do before setting out to build a new PC. Power supplies aren’t as exciting as the best graphics card, but every PC component in your rig will depend on your PSU for power. You don’t want to compromise on a PC power supply, even if it means you’ll have less cash for one of the best processors.

Still, finding the best PC power supply doesn’t have to cost an arm and a leg. Even if you’re trying to save some cash, you can find a great deal on many of the best PSUs. Don’t worry, there are still high-end power supplies, rocking all the RGB lighting you’d expect and enough power capacity to power a small village – or one of the best gaming PCs with two RTX 2080 Tis in SLI. No matter what you’re looking for, you’ll find the best power supply for your build right here.

Finding the best PC power supply is incredibly important, as if your PSU dies, replacing it can be a major hassle. And, you probably won’t know your PC power supply is dying until it’s too late, as many of the symptoms are hard to detect: they can be as subtle as some lost power efficiency and as obvious as having your PC burst into flames. So, do yourself a favour and pick up one of the best PC power supplies today, so you don’t have to worry about it tomorrow.

The Corsair RM750x scores the top spot on this list for one simple reason: it’s the most well-rounded power supply you can buy today. On top of a 10-year warranty and an 80 Gold Plus efficiency rating, the Corsair has a fully modular cable system. This means you only need to install the cables you need – you can say goodbye to the mess of cables and shoddy airflow that non-modular PSUs endure.

If you’re on the market for an affordable power supply that doesn’t cut too many corners, there aren’t a lot of options right now. So, an economical power supply like the EVGA 500 B1 may be right up your alley. For less than the price of a new game, you’ll get a full 500 watts of power transmitted through several SATA cables and two PCIe cables. This is hands down one of the best power supplies because it covers the bare essentials and nothing more, which is exactly what a budget PC component needs to do. The three-year warranty is a nice touch, as well.

Even the best PSUs seem to have extremely loud fans, and unlike case fans, it’s not exactly easy to replace them. Luckily, the Straight Power 10 line-up runs nice and quiet. Options range from 400w to 700w, and they’re SLI and Crossfire certified. They’re also modular, meaning you only need to use the cables that are necessary for your build.

The best PC power supplies, unfortunately, tend to be giant hunks of metal that don’t fit into smaller PC cases. However, the Silverstone SFX SST SX550 is a compact power supply that fits in plenty of cases. It’s half the size of most of the other PSUs on this list, allowing for more room for better airflow. This makes it an easy pick for anyone building a mini ITX or micro ATX build, and you can even slide it into a mid- or full-tower if you feel like it. And, with small form-factor PCs being all the rage in 2018 – it’s easy to see why the Silverstone SFX is one of the best PC power supplies.

This is all topped off with an 80 Plus Gold efficiency rating and a 10-year warranty – not only will it look good, but it’ll deliver power efficiently and last forever while it does it.
