Antec High Current Gamer 620W Power Supply Review


Closer Look:

The Antec HCG620 Is finished in what is now a very popular slightly textured matt black paint.















Hexagonal holed exhaust grill, small mains on/off rocker switch and model number label on the rear and a plain front face with cable exit port. The cable set is sleeved all the way into the power supply and protected from damage by a plastic liner on the exit port. The side panels sport the same Antec 620W label in red. The nine-bladed cooling fan is covered by an externally mounted black grill bearing the Antec logo at its centre. A comprehensive specification table occupies the bottom face.




The Antec HCG620 comes with a comprehensive connector set that includes two 6+2 pin PCI-E and a 4+4 pin ATX12V/EPS12V.


The 135mm cooling fan is by Adda, model number ADN512MB-A90 and rated for 12VDC at 0.2A. It uses a ball bearing system, runs at a maximum 2050RPM with 37.8dBA. A clear plastic baffle is installed just behind the fan to direct the airflow where it's needed.


The printed circuit is compact and reasonably well laid out. The electrolytic capacitors are all rated at 105°C and a mixture of Nippon Chemi-Con and Rubycon, both reputable manufacturers.


The Antec HCG620 packaging is minimal and may not survive many postal systems without a little extra help, two layers of corrugated cardboard between the power supply and the outside world may not be enough? The accessory bundle is basic and doesn't even include a user manual although it's downloadable on the Antec website. The build quality is satisfactory so all in all, at its price point, it's a reasonable enough package. Let's move on and see how well it performs.
