Deepcool PQ-M: Modular PSUs for Quiet and Powerful PCs

Deepcool’s PQ-M series modular power supplies provide high efficiency and stability for high-performance and quiet PCs. Through the use of Japanese components, including the famous brown Nippon capacitors, the manufacturer was able to achieve a system with a completely turned-off fan at low load.

The PQ-M series includes the PQ650M, PQ750M, PQ850M and  PQ1000M models.

The body of the PSU received a lacquered finish. Small turquoise accents were used on the logo and toggle switch, which stand out against the overall black background. The dimensions are the same in all cases – 150 x 140 x 86 mm (W x D x H).

The cable system is fully modular, so you can leave only those involved. The package includes a main cable 20 + 4 Pin (610 mm), two 4 + 4 for powering graphics accelerators (650 mm), three PCI-e (6 + 2) 675 mm long, two SATA with four connectors on each (450 mm), one SATA 2+4 Pin (450 mm) and one for connecting peripherals 4 Pin (450 mm).

For cooling, a 120 mm fan with hydrodynamic bearing is used. The fan runs according to a set curve, and a hybrid silent mode can be activated with a button, in which it completely stops at up to 30% load.

The manufacturer uses Japanese capacitors (105°C) and uses an optimized platform that reduces ripple and noise. All four models are 80 PLUS Gold certified.

Of course, all major protection systems are provided: OPP, OVP, SCP, OTP and OCP. The company also provides a generous 10-year warranty.
