DeepCool PQ850M

Today, we are looking at a product from a somewhat less well-known company, in North America, in the PC enthusiast realm; Beijing DEEPCOOL Industries Co., Ltd. DEEPCOOL is a Chinese company founded in 1996 that has generally been known for its line of air coolers, all-in-one liquid coolers, cooling fans, computer cases, and power supplies. Today, however, it is the power supply side of the house at DEEPCOOL that we are most interested in given their lower profile here in North America. The unit we are looking at as our first DEEPCOOL branded power supply is the PQ850M produced by Seasonic.

Seasonic is one of the older companies producing consumer power supplies having been founded in 1975 and entering the PC power supply production market in 1980. During more than 40 years as a company, Seasonic has cultivated lines of power supplies that are today some of the standard-bearers for efficiency and quiet computing. This focus, and its reputation for quality, has led to an explosion in production as Seasonic can be found providing OEM services on various model lines for Antec, XFX, Corsair, PC Power and Cooling, and of course under its own Seasonic brand.

Keeping It Cool, Deep Cool

The DeepCool PQ850M is the first power supply we have seen from DeepCool. As it sits today, this unit is clocking today at 850W which is an interesting number. As lots of people have noticed during the last couple of years, supplies of various electronics parts have been very constrained. As such, we have not seen a lot of power supplies much larger in capacity than this and, in fact, we have a whole bunch in this range coming online for review as this seems to be the “sweet” spot for high-capacity units at the moment. So, in that sense, DeepCool is going to have to do a bang-up job today to stand out from what is about to become a very crowded field. Before moving, let’s see what DeepCool has to say about the PQ850M:

Introducing a new generation of power reliability, the DeepCool PQ-M Series 80 PLUS Gold Modular Power Supply delivers high efficiency and stability for performance PC systems needing ultra-quiet operation with silent fan modes.

In our dedication to the mission of self-improvement and higher quality standards, the PQ-M Series PSU is a commitment from DeepCool to provide a trustworthy and reliable power supply. With a strong and dependable foundation, DeepCool is helping build better systems today that meet the expectations of tomorrow.

Carefully constructed throughout with quality components to ensure pristine power output quality. The modular board is hard connected to the circuit platform instead of traditional cables for added rigidity and less signal noise.

A fine-tuned silent fan curve helps produce a perfect balance between cooling and silence, with an additional fan stop option during low-temperature conditions. A rear fan control button also allows the option for setting a minimum fan speed when fanless mode is not preferred.

Fluid Dynamic Bearing (FDB) fans are considered the best-in-class for operating noise and life expectancy compared to other fan bearing types. The hydrodynamic and fluid-based properties greatly reduce friction and vibration which enables better reliability and quiet operation.

Let’s move on now and see what we can expect when a user purchases the DeepCool PQ850M power supply in retail in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
