While these are the voltage/amperage specifications that are listed on the Mushkin website, there are also a couple of other features that I thought are worth mentioning. The major one being that this power supply uses Quad 12V rails. Instead of the standard 1, or in some bigger units 2, this baby comes loaded to bear with four 12V rails to supply you with all the power you could ever need. One of the other major features that I found is that this unit has something dubbed “Rail Fusion”, which combines the 12V rails to give you that little bit of extra power for multiple GPU/CPU configurations.


Installation is nice and simple. Unplug all the connectors in your case and then unscrew the power supply. Mount the new one into the same spot, and then run only the cords that you need. No need to try and hide excess cords with this power supply's modular design! After double checking all of your connections, you are ready to go with your brand new 650 Watt Enhanced Mushkin power supply!


Test setup
  • Intel Q6600 ES
  • Intel Bad Axe 2
  • 2 x 1 GB Mushkin Xp8500
  • 2 x 750 GB Seagate HDD’s
  • Mushkin 650Watt PSU
  • Windows XP Pro SP2

For testing I will be looking at idle and load voltages as reported via software, as well as idle/load voltages reported by a digital multimeter. To load the machine, I will be running 3dmark06 and OCCT in the background to get the maximum load out of my hardware.
