Cooler Master UCP 900W

Cables and Connectors

The large mass of cables is nicely bundled up during shipping, and all are sleeved with a black mesh, including sleeving in between connectors. This can increase the cost slightly, but for those who are fanatical about having clean wiring it's a nice extra. There are a total of four 6-pin and two 8-pin PEG connectors for graphics cards on four separate cables; two of the cables have a 6-pin and 8-pin connector while the other two each have a 6-pin connector. Some users might have difficulties with using the 8-pin connectors on certain 6-pin graphics cards, but with many of the newest GPUs requiring an 8-pin and a 6-pin connector there shouldn't be any serious problems; after all, it's unlikely people running old hardware are going to go out and buy a power supplies like this.

There are a fair number of peripheral connections available on several harnesses, but the overall harness length may not be long enough for a larger chassis, as the longest harness is only 75cm. Again with the 900W rating, it seems a lot of users would be likely to have a larger case that provides for better cooling opportunities, so that's something potential buyers will want to consider. The ATX cables are 60cm and 65cm long, which should work well whether your power supply is in the traditional location or at the bottom of your chassis (like in Cooler Master's own Cosmos case). However, there are still cases where you may require longer cables, so pay attention to that area before purchasing this power supply for use in your favorite chassis.

The Fan

The Cheng Home Electronic fan branded SuperRed can be found in many of the Acbel-made power supplies from Cooler Master. It spins at up to 2000RPM, which we will see later in our tests. For a 120mm fan, that should be more than enough to cool the 900W PSU, but at maximum speed the fan does get moderately noisy.
