Power supply manufacturers condition us to think that efficiency is the one variable you need to pay the most attention to. But we have a suite of tests that more thoroughly taxes PSUs. Can these four inexpensive units under $70 make it through unscathed?

Last week we previewed the first four mainstream gaming cases in our 11-way sub-$100 round-up. Now we get to build four systems and test them. What other features will we uncover along the way, and how will they affect thermal and acoustic performance?

Gamers demand a lot from their computers, starting with the PSU. Therefore, almost every PSU manufacturer sells products optimized for gaming PCs. We introduce ripple and noise testing in this roundup to further improve our power supply evaluations.
