How We Test Power Supply Units

PSU Reviewing Is Hard Work!

In this article, we described the necessary equipment needed for a proper PSU review and outlined our testing methodology, which includes a rich variety of tests. As you have probably noticed, PSU reviewing is a complex, time consuming and expensive task. Even if you possess all of the necessary tools, you need to have the proper electronics background as well so that you can dismantle the PSUs without damaging them or harming yourself. You also need to be able to provide an accurate analysis of the PSU's platform and its components in order to judge its build quality. PSU reviewing admittedly is a hard job, but someone has to do it and, thankfully, we enjoy the work!

    Nobody can fault you guys for not being thorough enough! All we can wish for is that you do these tests a bit more often. I'm at a loss how to navigate the PSU field, and a "Best Picks" section for PSU's would be tremendously helpful.

    Really good article, it is now nice and clear how you guys go and test the power supplies, and as JPNpower said, no one can fault you guys for not being thorough enough.

    @JPNpower= I also think a best psu for the money article would be nice but the power supplies in the market pretty much stay the same. We may go for months before seeing any change in the list.

    Looks legit, Aris.

    THW used to be the laughing stock of PSU reviews, but your recent reviews have changed all of that.

    Keep up the good work!

    I'll make one and submit it through bb-71 to get stickied.

    OK. If someone makes a psu list I'd rather see it from you (or the mods). Good luck.

    It will be a group effort for sure :)

    It would be nice if all manufacturers could do this testing and publish results when they build the things, or even better for it to be a requirement. Then at least there would be less junk PSU's on the market.

    Or more fake reviews.
