You are introduced to the Antec High Current Gamer 650W PSU with a normal size power supply box with lots of indentification displaying which series and model that you have along with 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 manufactures and put a box inside of a box. Once you open the next box, you find the power supply with a nice fabric bag over it 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 nice honey comb mesh design to be able to exhaust any heat out of, the power supply plug connector and a switch to be able to switch the Zero RPM mode or Hybrid mode on or off.

At the top of the PSU you notice more honey comb pattern 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.

At the bottom of the PSU you have all of the specification and wattage broken out by rail.

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

Test System, Installation and Performance 

The system being used with this PSU is my Retro test bench setup.  It consists of the following parts:

  • CPU: Intel Xeon X3450
  • Motherboard: Asrock P55 Extreme 4
  • Memory: OCZ Gold 4 x 2gb 1600 mhz
  • GPU: Sapphire HD 4890 Vapor-x 1 gb, MSI HD 4890 1 gb
  • CPU Cooler: be quiet! Dark Rock TF
  • Storage: Sandisk Ultra II 240gb ssd
  • PSU: Antec High Current Gamer Gold 650w

Installing the PSU was very easy and straight forward.  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 with the extra capacitor in each cable it does make it a little thicker.  Having a thicker can be a little bit of an issue if you have a case that does not have 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 at 515W power draw on the entire system and the system show no signs of struggling or any issues at all. 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.


  • 80 PLUS Gold effieciency
  • Black Cables
  • Compact size
  • Quiet with the ZERO RPM mode
  • 100% Japanese Capacitors for efficiency and life expectancy
  • Amazing 10 Year warranty


  • Although very useful, the extra capacitor could cause issues in cases that may have very little room behind the motherboard


9.6 out of 10
Bottom Line Overall, Antec has designed a great power supply with their new High Current Gamer Gold series, specifically the 650W variant. If you are looking for a 650W, 750W or 850W PSU at a great price, look no further than the High Current Gamer Gold series by Antec.
