Questions and Answers

Do you have you a question about the be quiet! System Power 9 (600W) Power Supply 80 Plus Bronze?

Q: Does this item come with a UK mains kettle lead? I know beQuiet sometimes don't include them
Answer by Website User on 14th July 2020
You are right that Be Quiet often doesn't include power cables, and since they do not list it on the box contents we will say it does not come with one. -MR

Item was faulty. Was told to bring in the old one and purchase a new one the same day and they would refund me for the old one. Then two weeks later I was told they have tested it and its working fine. Which it definitely was not, it was tested by a computer engineer and a professional IT repair shop which both said it was faulty. Now I have two power supplies. In the future I will buy from Argos or PC world. Im even questioning if there products are authentic or possibly copies made in China. First review Ive ever written on TP and thats only because CCL wanted me to write it.

The product works great with low level noise from the fan and no issues at all with it. My only problem is that the wires are a lot thicker than I expected. Im glad its well protected however somehow the cover on the wires got caught on pieces of my computer.

Good value for a 600w PSU. No ketchup & mustard cables in sight and quiet just like the name on the box.


August 2020

Works great. Very quiet. Amazing value for money. Not had any problems so far and don't expect to :)

Excellent PSU for the price. Powers a Ryzen 5 and 20 series nVidia card with no issues. Even works for overclocking!


June 2020

Runs nice and quiet. My major complaint is that it has far too many cables with connectors quite close together making cable management hard work.


June 2020

I wanted a silent psu and the fan on this one is very quiet. The cables are a bit on the short side, and so the cable management was not so nice as I would like.


June 2020

excelent product


November 2019

solid power supply thus far and very good price for the 600W


June 2019
