INTRODUCTION

   Even though owners of the latest Radeon RX 7900 XT/XTX cards were faced with a nice surprise when they found out that they didn't have to swap their old power supply units for new ATX 3.0 & PCIe 5.0 one this will not be the case when the new Ryzen CPUs come out. The same of course applies for Intel's upcoming 14th generation CPUs and even though consumers will not be "forced" to pair these with new power supplies there will certainly be some benefits for those who will. AMD may also incorporate the new +12VHPWR standard with their upcoming Radeon RX 8xxx series of graphics cards (NVIDIA most certainly will just like with their GeForce RTX 4080/4090 cards) so in the near future the reasons for owning an ATX 3.0 & PCIe 5.0 power supply unit will keep piling up. In early June three of the latest ATX 3.0 & PCIe 5.0 power supply units arrived in the lab and the Pure Power 12 M 1200W by be quiet! was among them.

   be quiet! is a premium brand of power supplies, PC cases and cooling solutions for desktop PCs. The products of be quiet! offer legendary quiet operation and first-class performance thanks the passion for quality and precision. Attention to detail is the key to perfection. Which is why our very own experts lead product conception, design and quality control from our headquarters in Germany. be quiet! sticks to its name: More than 15 years’ experience in the field of noise reduction and silence make be quiet! products probably the most silent ones on the market.

   In January this year be quiet! updated their Pure Power 12 M line of power supply units with full support for the ATX 3.0 & PCIe 5.0 standards. Back then however only the 550/650/750/850/1000W variants made their debut (1000W review here) with the 1200W one scheduled to be released at a later date. Well, the Pure Power 12 M 1200W was actually released roughly a month ago alongside the Dark Power Pro 13 line and just like its lower output brother it too is a fully modular, 80 PLUS Gold certified model (up to 93.7% electrical efficiency). It also sports a single +12VHPWR 600W power cable, two strong +12V rails (55A/50A) capable of delivering 100% of the units’ total power output (1200W), peak power output of no less than 1338W (although once again according to ATX 3.0 specs peak should now be up to 2.4KW for 100ms – can’t try it however), 4 PCIe 6+2 connectors and LLC topology. Needless to say, the Pure Power 12 M 1200W is covered by a 10-year limited warranty and is fully secured by an array of electrical protections including over-current (OCP), over-voltage (OVP), under-voltage (UVP), short-circuit (SCP), over-temperature (OTP), over-power (OPP) and Surge & Inrush (SIP).
