Antec HCG Gold 650w Unboxing

You are introduced to the Antec High Current Gamer 650W PSU with a normal-size power supply box with lots of identification displaying which series and model you have and a nice picture of the power supply. The Back of the box has all the specifications listed above.

Once you open up the box, Antec has followed like many other manufacturers and put a box inside of a box.

Once you open the next box, you find the power supply with a nice fabric bag encased in foam and a nicely packaged vinyl bag with all of the power supply cables inside.

A Closer Look at the PSU

Starting at the back of the PSU, you have a nice honeycomb mesh design to exhaust any heat out of, the power supply plug connector, and a switch to switch the Zero RPM mode or Hybrid mode on or off.

At the top of the PSU, you notice more honeycomb patterns to intake air into the PSU and behind that is your 120mm fan to draw air in to help cool the components inside. You also notice the Antec logo and also the series displayed here. Finally, at the bottom of the PSU, you have all of the specifications, and wattage broke out by rail.

At the front of the PSU, you have all the PSU cable ports that are nicely organized.

Power SupplyAntec High Current Gamer Gold 650w

Installing the Antec HCG Gold 650w was straightforward. Antec does provide you with four mounting screws and also some Velcro cable ties.

The cables are aesthetically pleasing as they are black and tend to not mess with the aesthetics of your build. The cables are not flat, and the extra capacitor in each cable does make it a little thicker. Having a thicker can be a little bit of an issue if you have a case without much room behind the motherboard tray.

Performance has been great over the last few days with the 650w PSU. Overall, with the dual HD 4890s in Crossfire, the system power usage during benchmarks got as high as 515W power draw on the entire system, and the system shows no signs of struggling or any issues at all. Additionally, with 54 amps on the 12V rail and up to 648w available max on the 12V, this power supply will not have any issues running some medium dual card setups.

I monitored the Antec HCG Gold 650w voltage rails using Hardware Monitor, specifically the 12v and 5v while under load and didn’t see any significant shift in the voltages with minor deviance of +/- 0.01.
