Cooler Master V Semi-Modular Series PSU Features
The Cooler Master Gold Guarantee standard means that, no matter what, we believe in our new line of 80 PLUS Gold power supplies to be the best choice for your next build. While we stand behind all of our products with warranty coverage, technical support, replacements, and parts services, the Gold Guarantee takes it to the next level with full support and replacement on our dime for 5 years – giving you extreme confidence in quality and performance.
80 PLUS is a voluntary standard for power supply certification used to help with efficiency and innovation. The 80 PLUS Gold standard not only helps increase efficiency over 90%, but also saves you money.
The Cooler Master V Semi-Modular series features a unique 3D circuit design providing high efficiency and improves the heat dissipation. It reduces the unnecessary cables which results in much lower crosstalk, signal noise and improves airflow.
It also features custom DC-DC module design (12V to 3.3V and 5V) that offers notably higher efficiency and voltage stability than the other designs. The internals of the VSM power supplies is cooled by an intelligent 120mm fan with speed controller and honey comb mesh that increases airflow for better heat dissipation.
VSM power supplies also feature a design that allows you to only connect cables that your system requires. Fewer cables mean less mess and better airflow inside your case. Nobody likes trying to figure out what to do with that bundle of extra cables and with a VSM power supply, you won’t have to.
Cooler Master V Semi-Modular power supplies use high quality Japanese capacitors for increased longevity and better protection. Plus it features a powerful Single +12V rail for superior load balancing and VGA compatibility.
