Antec NeoPower 650 Blue Review

I used the Coolmax ATX Power Supply Voltage Tester to check the reliability of the Neopower 650. I think the results speak for themselves. No typical consumer has enough components that draw power from the +5V and +3.3V rails in order to stress them. I did conduct the tests with the system I had and the Neopower Blue 650W passed every test within +/- 2% of 5V / 3.3V. I noticed hardly the slightest movement in the +12V rail readings during the testing process.

I am confident that for the price, under $140, the Neopower is at the top of its class in performance and stability. Not many PSUs can boast the reliability that Antec has put into their power supplies, and the Neopower 650 Blue is certainly no black mark on their record. I would recommend this for medium to hardcore gamers without hesitation.
