Here, you can see the entire bunch. Some of you will enjoy the view. The cables are all black, so they fit most users’ needs. They are sufficient in terms of number and length as well. Four 6+2 pin PCIe cables are included, measuring 600 mm.
The 12+4 pin PCIe is 600 mm long, and it's sleeved. The 24-pin ATX motherboard cable is 55 cm long (also sleeved), whereas the 8-pin ATX CPU leads are 60 cm long. SATA is 950 and 650 mm long, and the Molex lead is 950 mm. These cables are modular, so you won’t have to plug in the ones you don’t need in your system, reducing cable clutter in your PC. According to the manufacturer, we should find quality components inside, so let’s open it up.
This unit delivers enough power for most daily users, as there is a single +12 V rail with a total of 850 W (70.9 A), so the unit should manage even an RTX 4090.
be quiet! Pure Power 12 M 850W is a good-looking power supply (but it's a bit prone to scratching).
There is an on/off switch and no push-button for disabling/enabling the semi-passive fan operation (as it's not possible in this model). Next page, please.
Today we’re putting the new be quiet! Pure Power 12 M 850W power supply on our test bench. The company is mainly known for its PSUs and Hilbert has recently reviewed the Dark Power 13 1000W. On the same day (24th January), the Pure Power 12M series was officially announced. We reviewed the predecessors, be quiet! Pure Power 11 (in 2018, it earned the “Recommended” award) and Pure Power 11 FM (in February 2022, also “Recommended), and we wonder what has changed in the meantime for the Pure Power 12M. The main difference is the full ATX 3.0 compatibility.
