Do you have you a question about the CiT 300W Micro Atx PSU?

Q: How can I change the fan speed for the unit? Ideally I'd like it running near silent.
Answer by Dan on 5th April 2017
This power supply does not have any manual controls for the fan speed, it changes automatically depending on the load. -Danlevan

Q: hi could you tell me the length of all the cables except, the mains cable .thanks
Answer by Dan on 22nd February 2016
The manufacturer doesn't list any cable lengths and we don't have them in our warehouse to measure. CiT power supplies tend to be fairly short cables though. -Danlevan
