Cooler Master's new Ultimate Circuit Protection power supply is among the first to receive the prestigious 80plus Silver certificate for an efficiency of above 85%. With 900W of output power this PSU can easily handle every rig that you put it into. During our testing we saw very stable voltages, especially 3.3V and 5V delivered great results.

As always awesome review W1zz. Is this sold in the US? Did they give a US price point?

I was a little shocked they didnt make 80 Plus silver like with their real power pro M series.

I have to tell you:

1. The UCP 900W has 80Plus silver certificate (WarEagleAU)
2. with a modular cable-management will decrease the efficiency
3. the power cord is standard - it is for 16 amps ...

I got one of the beta units which seems to be the final product and just a marketing thing for the beta...

Anyways, I'm glad it got a good review as I'm using this as my main PSU now.

I would like to point out it can get rather hot, it seems the fan never really ramps up, as shown in the review from the noise it puts out at idle and load.
