I've had this alim for 3 years now, it's on its second full conf and it's still doing the job, as quiet as ever.
I'd recommend it without hesitation, BeQuiet is still a reference.
The fan on the product delivered was faulty because it was very noisy - a shame for a brand called be quiet!
Fortunately the LDLC after-sales service was reactive and replaced my power supply.
Since then, silence has returned and it remains inaudible.
I'm taking off just one star for this initial problem.
Quiet operation, just a whisper. Very satisfied. ***************************************
Particularly quiet, good length cables, nothing to complain about. One point to note: it's a semi-modular power supply: the motherboard power cables are not disconnectable. Now, a PC power supply without motherboard cables... ;-)
I have been using this power supply for several months now, it is of very good quality and the output voltages are really accurate, I recommend it.
Half modular power supply.
I've always found Bequiet to be top notch, nothing to complain about for me. The price/quality ratio is always good.
The power supply does the job in an ITX configuration with a recent GC. It doesn't cut out when there is a peak in power consumption, and it's not the one that makes itself heard, even if a 0db mode would have been nice.
I took this power supply to replace a cooler master M2 850w, which was starting to malfunction: on/off of the pc randomly, security mode for hours, impossible to do anything... the case of the power supply is slightly smaller than the old one. I'm not sure how to use the cable management system for my e-atx case, but I can explain: the power supply cables of the cm are ok to pass behind the mounting plate of the cm, the hdd cables are just right, but the graphics card cables are too short, so it goes through the front... for the maniac of a case without visible cables, it's going to be difficult, if not for the one who doesn't care, no problem
A power supply that does its job, no more and no less.
The semi-modularity is very practical as it avoids having 50 cables that are useless.
Excellent power supply. After sending my LDLC QS-550+ power supply under warranty, which was making a worrying noise, I was offered an LDLC US 550+. This one was defective, and was replaced by another model, also defective. I wasted two months exchanging packages and dealing with the service department. All the other power supplies I tried alongside it worked perfectly.
This one is one of them, and does its job perfectly, very quietly. No regrets
