Very good and silent

I am using the Pure Power 9 600W power supply from be quiet! since few days and I tested it. I had big expectations from be quiet! and they got fulfilled, I like the power supply a lot.

The design of the power supply is very nice, it is mostly in black but it has also orange. There is a circle around the fan which is colored orange and it looks very good. Directly on the fan there is the be quiet! logo in orange and white which looks pretty. On the side of the power supply you can see the be quiet! logo stamped.

The build quality seems very good and there are no sharp edges. Be quiet! is known to use good quality components. The paint is spread even and there are no free spaces. Unfortunately the paint is not much resistant to scratches and you have to be very careful with it.

A very important aspect is that it has all protections (overvoltage protection for example) to protect your components from damage. With this power supply your components are safe and they would not get any harm if anything bad happens. I would not recommend a power supply without protections because a power supply is the most important component of your system. Without the inbuilt protections the whole system could get destroyed. It is very efficient and has a 80 plus silver certification which a power supply is getting when it has up to 91% power efficiency.

It can run a dual GPU set-up but you can`t use two GPU`s that are using a low of power since the power supply can deliver up to 600w. The new video cards that are coming now out use less power and a dual GPU set-up would not be a problem.

You can`t hear the power supply even under high load you can`t hear any noise which is very good for my ears. My old power supply was getting noisy even when it was not under high load. Like everybody else I like that my computer does not make much sound. The fans are very good built and they are made very silent.

The semi-modular cables make a lot of free space in the case and the airflow can take also advantage of it which keeps the temperatures lower. It is easy to install and the size is compact but the cables would be a bit short if you have a big tower case. In my case the cables are long enough since I have a ATX case.

The 3 years warranty could have been extended to 5 years and the cables could be a bit longer for better cable management and big cases. Also the price seems a bit too high since you can buy the Straight Power 10 600W power supply from be quiet! for a little extra price and it has even better features.

After all the good aspects I can highly recommend the
Pure Power 9 600W supply and I like it a lot. It is efficient, cool looking, very quiet, high quality build and it has good features. If you need more power for a power hungry dual GPU set-up and overclocking you can go with a Pure Power 10 supply from be quiet!

The new boss of my case

I've been running this PSU for a week now and I just have to say that I love it. It's nice to actually have a PSU that you know you can rely on, especially because my last PSU was a Corsair CX 600, which also treated me well but has a bad rap sheet.
The first thing that you notice about this PSU is the beautiful looking finned fan and the orange accent around its housing. The overall PSU feels well built and the "be quiet!" logo embossed onto the side completes the look nicely.

This is my first modular (or semi-modular) PSU, and although I used all but one of the cables, I noticed that the black plastic sleeved cables were much better at playing nice and had less of a presence, making cable managing a lot easier than my last PSU. Another nice rare feature you'll find on this PSU is that it has 4X PCIe cables, which is unusual for its wattage. Granted the 600W it supplies is not ideal for a lot of SLI/CF setups, but the cards coming out recently seem to just get better and better efficiency wise, so this PSU should be more than capable of powering up at least two current mid-level Nvidia cards.

When it comes to noise, I have no complaints. I can't hear the PSU fans over my other fans and I run a pretty silent ship. My system consists of 2X Corsair SP fans for my CPU Cooler, EVGA ACX 2.0+ for my GPU cooler and I always keep my case fans on low.

All in all I've very happy with this PSU, and if it lasts me into my next upgrade bracket I'll definitely consider replacing it with another be quiet PSU.

Great PSU But set our expectations

I received this as part of the competition on the Overclockers forum. I connected it to the pc in my home recording studio as my old PSU could get quite loud.

The first thing I noticed however is this is not a perfect solution, there is still audible noise in the background from the PSU when the computer is on and idling. It's not quite as bad as the old PSU but it is still there, however where it shines is the noise doesn't increase much if at all no matter how much load it is under.

Having not used a 'Silent' PSU Before I wasn't sure what to expect, however my advice would be, if you are looking for a completely silent PSU (no noise at all), You will need to go for something entirely fanless, however it does a great job of stopping noise under load. Perhaps it would be better suited in a gaming machine?

Be Quiet the silent behemoth!

Well, this is the 2nd Be Quiet i have had the privilege to own.
I knew how good this brand of PSU was because I also have the 430w model running in another machine which has been flawless!
They really do live up to their name. I cannot hear this one. It is to me 'silent'. The PC i just put it into is sitting on the desk and i was aiming to build a 'silent' PC and this does the job admirably.
If you want a PSU that you don't want to hear then go for the BeQuiet range. It comes with more than enough cables for me and all are well sleeved in black plastic and are flat which i find great for tucking out of the way. The 24 pin is sleeved but round which again is ideal.
I like the fan guard and the trim around the fan! Nice touch.
600w is more than enough for my system. It runs everything with loads to spare.
The packaging is smart and clean looking and the PSU and cables packed nicely in the box.
I highly recommend this PSU and the brand. Its the 2nd one i have owned now and i definitely would buy from this maker again. Quietness is very important for me and this delivers.
Also, when you buy from OcUK you know that you are buying from a quality supplier which is very important.
So, i am very pleased with this Power Supply and i have fitted it my ITX case which is sitting on my desk and it is doing a superb job. Silent and efficient!
