The Cooler Master 80Plus Gold V550 V2 power supply has everything to fit into the case of demanding users: fully modular cabling, complete connectivity and 16 AWG PCIe cables, very high quality Japanese components, high energy efficiency and high efficiency with 80PLUS Gold certification. A perfect solution for your next-generation configuration.
The V550 V2 offers a semi-fanless design with a 135mm fan. Above 40% load, the power supply is perfectly silent. A button allows you to change this behaviour to a normal mode which will increase the heat dissipation.
The cabling is often the least annoying part of assembling a PC. The V Gold V2 series can't solve all your wiring problems, but it does help a little. The 100% modular design means that your PC is not cluttered with excess cables. This reduces the volume of cable and thus increases the airflow in your case.
The V Gold V2 is a professional quality power supply unit. It offers superior performance to the 80 PLUS Gold efficiency. That's performance, stability, reliability, longevity, and more. This quality starts with the technology used inside. The LLC converter and DC-DC technology, manufactured with Japanese capacitors offer a power supply that provides reliable and stable voltages for safer performance and higher efficiency

A power supply that runs a Ryzen 7800X3D + an RX 7700 XT with RGB fans without a problem. Gold 80plus for a reasonable price, it's just perfect.
I wanted to take advantage of a promotional offer to update my "old" Seasonic S12-500 (almost 15 years of service) during a configuration upgrade. It was a bad idea because the 12V oscillates between 9.5 and 10.8V max ! I was able to realize this after a suspicious crash of the PC, something that had not happened to me for a long time. I may have fallen on a bad power supply but I don't think I'll take the risk so I'll send my S12 back and reassemble it until it's really "out of date". (in the end 500W despite a slightly less good performance will be enough for me)
I was forced to reduce the speed of a RX5700XT because the PC was shutting down with some games randomly. Replacing a branded 650Watt power supply, I gained in storage space (less cables, in a compact case it's important).
I really appreciate its silence and its high energy efficiency.
This power supply is incredible in its size, I was shocked when I received it!
Unfortunately after several weeks of use I am really disappointed...
The power supply is noisy! I was expecting it when I saw its size but I'm not just talking about the fan (which has a very strange curve, from 15% of use it blows at 100%!) but a strange whistling problem that continues even when the machine is turned off!
I will contact LDLC support and edit my note accordingly.
[Update] Following a power supply exchange by LDLC, I have exactly the same problem... I have read on other reviews that there is another version of this power supply with these problems solved. So it's a bit of a hit and miss. This will be my last Cooler Master power supply and purchase on LDLC. I'm not going to wait weeks to get another not so great power supply.
Small in size but powerful, barely heats up when fully charged and is super stable. The cables are very short and stiff. Otherwise, it's fine.

Silent and efficient with a 3070 TI, quite a lot of connectivity so nothing to say, package received in one day well packed
Coupled with a lian li mini o11, the installation without problem, I do not find it noisy. Everything is perfect.
The other review explains the problem with the old version well.
But the cooler master service is very responsive and sent me the new version without any problem!
So 2 stars is not constructive!
I received the new version and it is superb and without noise! Nowadays it's the new versions that are sold and at worst you exchange it.
Even when the after sales service works well, the French still complain... The fault is human.
Good power supply overall, it says "stable and quiet". For the stability no problem, on the other hand silent, not really when the fan is running at 100%. Reason why I removed one star.
