Antec NeoPower 650 Review

Lowest Prices

Conclusion:

Antec has consistently offered high quality power supplies, and the NeoPower 650 does not deviate. The component system offers to reduce wire clutter, but for a full tower case, as in this build, all the cables were used except for the second PCIe cable. The NeoPower 650 would be great for HTPC users looking for a high wattage, high quality power supply that is quiet, and modular. During testing the voltage held steady on the 12V, 5V and 3.3V lines and there was minimal fluctuation on the lines. Coming into the review I had thought that the 80mm fan would be whining the whole time, but it was whisper quiet and was not an issue even when ramping up under load conditions.

The NeoPower 650 performed well given the hardware that was used. Calculating the wattage on the test system puts it at approximately 600W (depending on the calculator), so loading the system puts it in the 80-90% efficiency range. As indicated by the graphs, there was very little fluctuation in the lines and they held very steady. Antec needs to look forward and add more SATA connectors to accommodate current trends. The other missing item was the fan RPM monitoring connector, which is nice to have to keep an eye on things.

Pros:

  • Component cables reduce wire clutter
  • Stable rails
  • Active PFC
  • Very quiet
  • Powder coated finish
  • Three 12V rails

 

Cons:

  • Only four SATA connectors
  • No RPM monitoring for the fan
