Power Supplies Buyer’s Guide

We think that the power supply is arguably the most overlooked component for amateurs building a computer for the first time. While a power supply won’t provide sharper graphics, greater processing power, or quicker memory access, they are the crucial component to make your computer actually run, and investing poorly can result in long term negative consequences for your system. But investing in more than you need can take away critical resources that could be spent on internal hardware.

The best power supply for you is going to be largely predicated on the demands of your specific PC. But our guide can help you understand exactly what you need so you can get the power supply best suited for your PC.

Efficiency Rating

If you want the best power supplies for your PC, the efficiency is going to be one of the most critical factors you need to pay attention to. Fortunately, the 80 Plus certification system that all decent power supplies use makes it easy to identify the efficiency of specific power supplies. Power supplies fulfill the goal of transferring AC power to DC power, and some power is naturally lost to height along the way.

Ideally, you need an efficiency rating of 90% or higher for the best power supplies. You can find this much power in the 80 Plus Gold and 80 Plus Platinum. But if you don’t have your heart set on the best power supply all around, an 80 Plus Bronze will provide you with pretty great performance. Naturally, 80 Plus Bronze power supplies are going to cost significantly less than 80 Plus Platinum power supplies on average.

Wattage

A power supply needs to power everything from graphics cards to motherboards to speakers. Anything plugged into your PC is going to need to run on the power supply. That means that the best power supply one is a model that’s well matched to the actual wattage of your computer. Too much power, and you’ll be spending money on wattage you don’t need. Too little, and you can’t properly power your PC at high loads.

That means you need to consider the power output for each component when seeking out the best power supply for your need. Fortunately, there are a number of calculators that can accomplish that process for you. OuterVision offers one of the best, but if you haven’t built your computer yet or you plan on expanding your PC in the future, you may need to make some manual adjustments to find the best PSU.

Modularity

A fully modular design is one of the most frequently touted features in a power supply, but what exactly does it mean to be modular? Modular PSUs use detachable cables, and that means that you can spend less time managing your cables and make better use of the space inside of your computer case. It can have a positive effect on the ventilation of your PSU.

On the other hand, the modular cables are proprietary, so in rare cases, you may have to go out and find a replacement cord for a PSU with a modular form factor. And while modular PSUs can sometimes take up more space in a case, we generally recommend opting in to it. It’s a design choice that typically has more advantages than weaknesses.
