Best Power Supplies

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.

MORE: All Power Supply Content

When it comes to power supplies, the saying that "more is better" doesn't apply. 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 1080s. 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.

    It takes a lot of courage to give a novice opinion when you're a novice. First, I congratulate "Tom's Hardware" for their involvement and contribution to the AC-DC (analog certainty-digital confusion) world of computing hardware. I like that they probably didn't leave out a single mfr.from their list. Second, I like that they covered all price, value and performance points. I like that they listed "cons' for their selection of "best" power supplies. There are "cons" at every price point and plenty of them. It makes me wonder just what the "best" really means!...particularly in light of spending $400.00 dollars. I wish there were some "bests" in the sub 400 watt range. I believe (maybe mistakenly so) that mfr's will be (are) anxious to sell off these Hi Watt juice making heat pumps due to changes in GPU technology as well as new high quality board graphics. Lastly, I like that Tom's and the author didn't include a single non-rotating solid state unit in the bunch. I would really like to see some "bests" in that upcoming article. Signing off, I am truly the dinosoar...landing.

    According to your own reviews the EVGA SuperNOVA 1000 G2 beats out the FSP AURUM PT 1000FM in both relative performance and performance per dollar. So...how is the FSP the best again?

    Thanks to "Tom's hardware", it really taught me a lot of knowledge.The 4000-750 watts power supply should be the most widely used, and the office system even requires a large number of 250-350 watts of power supply.It will be very meaningful to not know whether "Tom's hardware" can be targeted to do some horizontal comparison evaluation and recommendation.Thank you very much for your work!

    The VS500 was added at the top of the list just a few days ago. Good to see someone take it down because you are spreading misinformation of the VS series being good.
