Best PSUs

Depending on its overall performance, your PSU plays a big part in determining reliability, so you have to be careful when it comes to picking the right one for your machine. A good PSU should also have the protection features able to save your components, including the power supply itself, should something go wrong.

The recommendations below are pulled from the top-level awarded products from our PSU reviews. As we continue reviewing units, this list will evolve and grow. continually representing the best of an incredibly important component.

August 2016 Updates 

With so many new products released during the last few months, the there was no time to rest. Usually August is a very quiet when it comes to new products, however this year many companies decided to break tradition by sending in some really interesting products for evaluation. Without a doubt, the most interesting of all is the new Seasonic Prime series, which so far look amazing. We’ve already finished one review of a Prime unit, which will go live towards the beginning of September, so stay tuned!

Three PSU reviews were published in August, with only one unit managing to earn an Editor’s Approval award: the Thermaltake Toughpower DPS G RGB 1250W.

Power Supply Charts

When it comes to power supplies, the rule of thumb that "more is better" doesn't apply any more. Before deciding on your next PSU purchase, you should calculate how much power your system draws from the wall and look for a capacity point that satisfies your demands. A few years ago, all high-end graphics cards were power-hungry. However, this changed with Nvidia's latest architectures. It's simply not necessary to buy a 1kW PSU for a couple of GeForce GTX 980 Tis. A 750W model will do just fine, leaving plenty of headroom for an overclocked host processor. Fans of AMD's flagship Radeon cards need to plan for higher power use, pairing them with PSUs featuring greater maximum output.

In the relative performance charts provided with each one of our PSU reviews, we create an index of sorts that encapsulates overall performance, including load regulation, ripple suppression, efficiency, hold-up time and the maximum power each PSU can deliver. Hopefully this makes your life easier, since you don't have to decipher several data-heavy graphs to reach your own conclusions. You only need to take a quick look at our index to see where your PSU of choice stands against its competition. The second most important chart, derived from the relative performance score, is performance per dollar, which we're betting will become your favorite as you shop for an upgrade.

    hi, I regularly read your articles. And I guess, I'm a geek, as I often look for better components even if my components are fine, for example my PSU, a Thermaltake London 550W. Nothing to complain about.
    Still, I just had a look and right now I would buy the passive and Platinum XFX XTS Series 460 Watts (or the 520W). Value is good here and I found a positive review...
    You might want to consider it in your tests...
    Regards
    Claude

    Seasonic's newest flagship, their "Prime series" units, probably deserve a mention as well. The prime 750w T unit (SSR-750TD), got a rare perfect score from JG. There are also 650w and 850w units so far, 10 year warranty. Prices are, more or less, competitive.

    the review of the Seasonic Prime is next. It took a while because of my heavy schedule (mainly).
    once it is posted then it can be added to the best picks :)

    I can't believe you didn't include a noise metric comparison. that was a big miss.
