Final Thoughts

As noted early on, Rosewill is in the business of selling quality products at a good price. This has been their business model for a long while, and the RX630 Xtreme is a worthy addition to their product line. Aimed at gamers, this power supply provided surprisingly good results given the test conditions it was put through. With a performance that was acceptable and a very nice outward appearance, this PSU is worth considering.

You will be limited to either a single high-end video card or a pair of mid-range boards, but this is to be expected with the power level of the product. The cabling harness provides enough connectivity for most systems and the cable lengths were long enough to work in all but the largest of enclosures. Any mid-tower being made should be well suited with the cabling of this PSU.

Pricing for this model has a MSRP of an unsightly $189.99US as posted on the Rosewill web site, but online retailers are selling this power supply for about $80US. At this price point, it is one of the most inexpensive units available in the 600-700 watt range with similar features.

As far as those features are concerned, this model comes with an efficiency rating of about 80-85%, has Active PFC (Power Faction Correction), protection from over-voltage, under-voltage, over-current, over-power and over-temperature. It also features four 12v rails and support for both SLI and Crossfire applications. While not one of the fancier power supplies ever tested, it proved to be both reliable and aesthetically pleasing.
