Double Ball Bearing Fan

Staying cool is one of the most important goals when a power supply is operating. A well-cooled power supply greatly increases its life span. The 135 mm Double Ball Bearing (DBB) Fan is ideal for quiet computing and is designed for longer life, guaranteeing hours of operation. The Thermal Manager, an advanced low voltage fan control for optimal heat & noise management, will allow your PSU to stay at an optimal temperature. And to top it all off, this PSU comes with a switchable white LED to complement any build.

80 PLUS® Bronze certified

Saving energy has become an important factor when choosing the correct power supply. The HCG-620M is BRONZE Certified, with an efficiency rating of up to 87%, resulting in energy savings year-round. This power supply provides efficiency during max and low loads and lives up to the performance standards that we are known for.


The HCG-620M is a hybrid modular PSU, this allows you to use only the cables you need, greatly simplifies installation and helps clear out space. This can also improve your airflow, because excess cables can obstruct and reduce airflow. The silent, whisper-quiet, 135 mm DBB (Double Ball Bearing) fan offers high-quality cooling performance with a long lifetime.

Reliability you can count on

The HCG-620M is backed with AQ5 - Antec Quality5 year parts and labor warranty, and you get unlimited access to Antec's incomparable technical support and customer service.

high standard in engineering

A power supply converts mains AC to low-voltage regulated DC power for the internal components of a computer. Several direct-current voltages are required, and they must be regulated with some accuracy to provide stable operation of the computer. This is where the quality of Antec power supplies differ from the rest. Antec's high performance 100% Japanese heavy-duty capacitors ensures the tightest DC stability and regulation. So you can rest assure that this power supply will last you for multiple builds to come.
