This Antec branded unit is using a high grade Hong Hua fan (Model: HA1225H12F-Z). This unit is built around a Fluid Dynamic Bearing for quiet operation and long life. It is rated 0.58A, at 12 VDC. Maximum speed is rated at 2,200rpm, producing 73.9CFM at 32.4dBa. You will notice the unusually cut plastic cover along the left side of the fan – this is to direct the air flow at specific parts of the power supply underneath.

As mentioned earlier in this review, Antec have paired up with SEASONIC for this power supply and as expected, the build quality is top notch, with stellar soldering throughout and quality components used in all key locations.

Inside are a fair few smallish heatsinks to aid with cooling key components. The power supply is using a full bridge LLC topology with synchronous rectification with DC-DC VRM’s for +3.3V and +5V rails on secondary. Input filtering starts on a small PCB with Y and X capacitors in place – moving to the main PCB for completion.

This unit adopts a high quality 105C rated Japanese Nippon Chemi Con capacitor in the primary stage, from their KMR series. It is rated 400v 560uF. I still have an 850W Seasonic Focus Plus Gold unit in our labs and its the same primary capacitor inside, but with slightly higher output, rated at 650uF. Regular readers may remember that Seasonic use two primary capacitors in their higher cost PRIME units.

In the secondary stage are a mixture of solid and standard electrolytics from Nippon Chemi Con. A solid, well built overall design from Seasonic.
