DeepCool GamerStorm DQ-M V2L 850W Power Supply Review

The DeepCool GamerStorm DQ-M V2L 850W uses a new platform from Channel Well Technology (CWT), which has the codename GPX. In essence, GPX platform is a downgraded GPU design (which we have seen in the Bitfenix Whisper line and the older DeepCool GamerStorm models). Its goal is to offer high enough performance at a lower price, meaning that it doesn't use the same high-quality parts that the GPU design utilizes. With higher quality FETs and a stronger boost diode, the GamerStorm DQ-M V2L 850W could be included in our Best Power Supplies article, but performance alone isn't enough. 

The design needs to be reliable enough to last for years to come, even under tough operating conditions, and it should also retain its good performance over time, because even PSUs age. DeepCool's new power supply line looks interesting, but it doesn't pose any threat to the highly po[CENSORED]r Corsair RMx and Seasonic Focus Plus Gold lines.

DeepCool decided to expand its GamerStorm brand with a new PSU line, with the codename DQ-M V2L. This line consists of three members with capacities ranging from 650W to 850W. Compared to the original DQ-M line, which is based on the top-notch CWT GPU platform, the DQ-M V2L uses the inferior CWT GPX platform with some modifications, which allow for higher performance and increased reliability. The latter is depicted on the ten-year warranty that supports these new PSU models. Finally, all DQ-M V2L units feature a single +12V rail design, contrary to the DQ-M members, which had several +12V rails.

The GamerStorm DQ-M V2L 850W is the flagship of the line, featuring enough power (and connectors) to support a potent gaming system. It is a fully modular power supply with regular dimensions. A few years ago a 850W PSU with 160mm depth would be considered compact, but nowadays, we find similar capacity PSUs with only 140mm depth. With a quick look at the specifications, we wonder why DeepCool didn't use a larger fan (e.g., 140mm instead of 120mm), since the chassis is large enough to accommodate it. A larger fan can provide the same airflow with a smaller one, but at lower speeds so its noise output will be lower.
