Rosewill VALENS-700 700W Power Supply Review
While Rosewill is likely not a go-to computer power supply brand to most people, we have been surprised with Rosewill's quality on two of its PSUs over the last couple of years. Today we review an $80 700 watt Rosewill unit that is rated for Gold efficiency, and well ... that is about all that marketing has to say about its Valens-700.
Today, we look at another new product from a company familiar to many HardOCP readers, Rosewill Inc a subsidiary of Newegg since its inception in 2004. Newegg was founded in 2001 by it's then parent company ABS Computer Technologies who has been a part of the enthusiast computer market since its founding (now defunct [H]Consumer covered a few of its fully built computer systems). Over the years, we have seen a few power supplies from the ABS Computer Technologies/Newegg/Rosewill conglomerate branded by both ABS and Rosewill.
Currently, however, the Rosewill portfolio is much more complete when it comes to peripherals in general and power supplies in particular than what we used to see from ABS. Today, we are looking at our third Rosewill branded power supply with the VALENS-700 (VALENS-700) produced by ATNG.
ATNG Power Co. LTD (I Horng Power Co. LTD.) is one of the larger providers of power supplies in various markets including the United States and is fairly well known to many users. As a company ATNG has been in business since 1987 and currently has a production capacity of ~900,000 units per month. ATNG branded power supplies can be found under other brands such as Rosewill/ABS, older BFG Tech models, Coolmax, StarTech.com, Fractal Design, Nexus, the ATNG brand itself, and others. Typically ATNG power supplies have not been what most users have considered to be a premier product offering but with the increased competition in the power supply market of late ATNG has released a number of new products that are of great interest to us.
Let's Hope This Goes Better Than The Battle of Adrianople
Today's Rosewill VALENS-700 is the just the third power supply we have seen sold under the Rosewill brand. Interestingly, the VALENS-700 is much more like the previous Capstone 750W than it is like the more recent Quark-550. As such, what we are looking at today with the VALENS-700 would be more of a mid-range power supply that also tries to pitch itself as a value proposition than it would be a real top tier unit. Given that this went stunningly for the Capstone 750W we have high hopes that the newer VALENS-700 can do much the same and maybe even improve a bit upon what we saw before. However, before moving on, let's see what all Rosewill has to say about this unit today :
80 PLUS Gold certified to deliver over 90% efficiency
ATX 12V V2.3 Ready, supports EPS 12V 2.92 and backwards compatible with ATX 12V 2.01
Active Power Factor Correction (PFC) with PF value of 0.99
Crossfire and SLI Support
Long lasting, ultra-quiet 120mm hydraulic fan
Over Current / Voltage / Temperature / Power Protection, Under Voltage Protection and Short Circuit Protection
UL, FCC, CE Certified
Extra-Long Cables Support Full Size Gaming Chassis
Well, that generic list of features seems very similar to what we saw from the Quark-550 and it still does not do much to make us feel good about the product we are about to see. Let’s move on and see what we can expect when a user purchases the Rosewill VALENS-700 power supply in retail in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
