The Xtreme 850W is packaged in a rather sleek black box, complete with a single red accent of its namesake, which looks to mimic Rosewill’s corporate colours. Inside the box, the components are packaged reasonably snug, and arrived without any damage. Included is a power cord and screws, and nothing else. It’s definitely a very sparse package, perhaps reflecting a more affordable price tag for the unit that Rosewill is pursuing. The Xtreme 850W can be found online at Newegg for $100, and it’s one of the least expensive power supplies you can find on the market for unit in this power range.
