be quiet! Dark Power Pro 12 1200W 80PLUS Titanium

Quiet power supply and very stable voltage

Bought this as a replacement for a 2013 Dark Power Pro 10 1000W which still works great, but hums a bit. This one is almost inaudible, you really have to stick your ear to the tower to hear the operating noise of this power supply. Be Quiet! has outdone itself!

Using for the moment with an average load of 25%, that is to say 300-320W, the voltages are "ultra" stable. In 3V and 5V, it does not move! In 12V, it fluctuates minimally, about 1%. This is what you want when you buy a power supply, because stable voltage = component with a longer life. As there is very little variation in voltage, there is also a gain in temperature on all components: -2°C on average on the SSDs, -5°C on the processor, -6°C on the motherboard VRMs, etc. I didn't expect such a difference at this level!

Of course, the price is a bit high (even with a 15% discount on the purchase), but quality has to be paid for. It's important to keep in mind that this is a key part of your computer, and that you don't change your power supply every day. I just wish I had the same level of equipment on a 1000W block.

Bad CPU cables

The power supply does not come with the correct cables for the CPU connectors:

There are :
a 10 pins cable (2 empty) -> 10 pins (2 empty)
a 8-pin cable -> 8-pin
instead of
a 10-pin cable (of which 2 are empty) -> 8 pins
a 10-pin cable (of which 2 are empty) -> 4 pins + 4 pins

As a result, it is not possible to power the 8-pin connector of the motherboard (there is no 8-pin connector left once the ATX 24 cable is installed) -> The second P8 slot of the power supply which should serve this purpose is waiting for a 10-pin connector (of which 2 are empty) -> it cannot be used with the 8-pin cable. When the 10 pin connector (2 empty) is too wide and does not fit well to feed the 4 pins of the motherboard (it should be a 4 + 4).

I have to order a CC-4420 and a CC-7710 cable in order to supply the motherboard with power ... but LDLC does not sell them.
