Rosewill Capstone 750W Power Supply Review

Rosewill Capstone 750W Power Supply Review Introduction

Several large retailers and
e-tailers around the globe have started their own in-house brands. While these in-house
brands are usually limited to input peripherals and minor accessories, the
largest companies do offer more in-house products, such as computer cases and
power supplies. Rosewill however is perhaps the first company which expanded to a full-fledged manufacturer and exporter, even though they initially started as an in-house brand. Rosewills product catalogs are
vast, ranging from the simplest accessory to the high end gaming cases and
power supplies. However, as the company just started acting as a stand-alone manufacturer, it is natural for users to be concerned whether their end products can truly stand their ground against well-established manufacturers. Today we will address some of these concerns through the review of the Rosewill Capstone 750W power supply.

The Rosewill CAPSTONE series is available in 450, 550, 650 and 750 Watt models in your choice of either modular or non-modular cables. All of the power supplies are 80 PLUS GOLD Certified, feature a single 12V rail and use a large 140mm fan to keeps things cool and quiet. All of the power supplies are 150 x 86 x 163 mm (W x H x D) and come back by a 5-year direct replacement warranty.

Rosewill sent us the Capstone 750W non-modular power supply to review today. This power supply has a single +12V rail rated at 744W output and 62 Amps. This is an 80 Plus Gold
certified power supply unit, which is
designed and made by a highly reputable OEM and is not your cheap $30-40 “generic” product. Rated at 50C ambient temperature,
the specifications of this power supply are very interesting, although not as
interesting as the retail price; with the Capstone 750W retailing for $114.99 + $3.99 shipping at the time of this review, it is
one of the cheapest 750W 80Plus Gold certified power supplies currently
available. As you can tell from the chart above, pricing for the Rosewill Capstone PSU series is all over the place right now as the modular power supplies are part of a promotion right now and cost less than the non-modular versions!
