Very decent power supply

Bought this psu on a very tight budget as an upgrade from a somewhat ancient power supply (it was installed around the time Nvidia brought out the 8800GTX!) and I've got to say I'm very impressed so far. This Cooler Master unit is a lot quieter and has eliminated all my issues with coil whine (though your mileage may vary on that as coil whine is dependant on all components in a system). The cables are plenty long enough, I was even able to run the 8pin CPU cable up the right hand side of my motherboard and across the top and still have enough slack to get it into the socket without any tension on the cable.

The only issue I had was, my particular unit was shipped with a EU plug type to my UK address. I'm not sure if they all come like this or if it was just an error on Overclockers behalf, but OCUK were very quick to rectify the problem after I contacted them and they immediately shipped a UK power lead.

Would definitely recommend this unit if you're a bit short on money but want a unit that will serve you well.
