Summary

The Rosewill Xtreme 850W is a power supply that delivers good features and performance when heavily loaded with a case full of power-hungry components.  From an aesthetic standpoint, the unit is housed in a glossy, dark charcoal, mirrored finish that should fit with just about any case setup. From a feature standpoint, unfortunately we don’t have a modular setup here, so you will have extra cables to tuck away in your case. The cable length, specifically with the 4/8-pin ATX cable is an issue, notably it’s about an inch or two shorter than it should be, so if you have a full tower case with a bottom-mounted power supply setup then you likely will not be able to route behind the motherboard tray. We consider 19″ the absolute minimum cable length, but 21″ is much more preferable, and the Xtreme 850W would benefit from a couple of extra inches in the cable length.

From a functional standpoint, the Xtreme 850W series has stable voltage regulation that doesn’t deviate very much, and has good efficiency but it doesn’t quite match some of its competitors just one step below in the popular 750W segment for a what is essentially not much difference in price. The only other issue is that the dual 80mm fan setup does not run very quietly, and certainly not silent as claimed. It will likely be drowned out in a case by a graphics card fan, but we think that’s nothing brag about.

The tradeoff here is that Rosewill has positioned the Xtreme 850W as a very affordable unit, and in that sense, it is one of the least expensive 850W units you will find. But just below at the 750W market segment, there are some compelling products if you don’t need the extra 100W of power. Either way, the Rosewill Xtreme 850W may not be a standout unit in any particular category, but it is a good all-around power supply that offers a successful combination of features, functionality, quality, and aesthetics at a very good price.  If you are on a very tight budget and are looking for a power supply with some higher horsepower at an affordable price, the Xtreme 850W is worth a good look.
