Introduction

If an ATX power supply deviates from the standard dimensions of 140 x 150 x 86 mm, we immediately think that it must be longer in depth. For the most part, that would be the correct assumption, given the trends of high output PSUs we've seen over the decades. On the other hand, we see the efficient designs allowing manufacturers to require less cooling capacity, and now we can find quite a few 1000+ W units that fit into standard ATX dimensions. Today we're looking into something that takes these advancements and utilizes them differently - the Enermax REVOLUTION D.F. 12 850 W, which has a reduced depth of 122 mm, reducing the volume occupied by the PSU by almost 13 %.



Now the main question might naturally be "why?". After all, if we have an ATX case, we are guaranteed to fit in a regularly sized PSU with a depth of 140 mm. With a regularly sized ATX case the benefits really might not be that appealing. You might be left with more working space for your cable management, but after all, regular ATX cases typically allow adding in at least a 150 or 160 mm deep PSU, often larger. Where this reduced depth PSU would be appreciated the most is small ATX PSU supporting cases. I myself run an ASRock Deskmeet X600 as my main machine, which, despite its modest dimensions, houses a full size ATX PSU. But together with an RTX 4060 Ti and all other components, I become really appreciative of any available space in the case that would improve the airflow inside.

Even if we disregard the size factor the REVOLUTION D.F. 12 850 W (a 750 W version is also available) is a very well specced unit with ATX 3.1 support and 80 Plus Gold efficiency levels, providing a very compelling package for the price. Before the usual vendor-provided list of specifications, one more nice detail - the PSU comes in both black and white colors. Today we're taking a look at the white version, making it a feasible consideration for a broader circle of potential buyers.
