Deepcool Gamer Storm DQ650-M PSU Review

Rating: 8.0.

Last year we took a first look at the new Gamer Storm DQ-M range of power supplies from DeepCool – in a 850 watt capacity. Today we analyse another model in their range – the lower power output 650W model. These power supplies have a healthy 10 year warranty and adopt all Japanese capacitors to aid with long term reliability.

Deepcool are well known in 2019 for their eye catching chassis designs. They have also focused recently on cpu coolers and some power supplies. This particular range of units has three models in the range – a 650W, 750W and 850W model.

Deepcool have partnered up with Channel Well Technology (CWT) for these supplies and the 850W model scored well in our labs in September 2018.

This power supply measures 152 x 88 x 162mm in size and weighs 1.60kg.

This unit is based on a CWT platform and more specific the GPU850V-G. In the Cybenetics scale it scores ETA-A and LAMBDA-A- efficiency and noise certifications and it is also 80 PLUS Gold certified. I was quite surprised to see that DeepCool didn’t adopt a 140mm fan in these units, to keep down noise while producing high airflow if needed.
