Power Supply Unit

Thermaltake has done a good job with the cable sleeving, all cables that have a similar function are sleeved in the same color. The ends of each sleeving are fixed with heatshrink, some other manufacturers are saving money there and show you just the bare ends.

While SATA harddisks haven't taken over the market, the additional SATA connectors are a nice add-on which help making your investment future proof.

The POLO12's power supply has a good amount of connectors. All are long enough even for bigger cases.

While running, three LEDs give the PSU a pretty blue glow. Very nice.

Inside Shots

The inside is well cleaned up like you can expect from a good PSU. On the second picture you can see two trimmers - the upper one, labelled VR1 changes the 12V and 5V output voltage. I could not find out what the second one does, it's not changing the 3.3V output.

The 12V line could be a bit more stable, the other voltages look really good.

The PSU fan is temperature-controlled. Speeds range from 1300 to 2800 RPM. At 1300 RPM the fan is very quiet.

120mm Fan

There's not much to be said about the 120mm fan except that it seems to be a pretty low-cost fan made by Everflow. It moves a lot of air at 12V but is VERY loud. At 5V and 7V airflow is barely noticable.
