The PCB and the connectors:

The tools for clocker:

Let’s start with the elements inserted on the PCB which can be interesting tools for overclockers. Of course, they will be few in number since this board is not intended for overclocking.

  • The power button: allows the powering up of the motherboard.
  • The reset button: allows to restart the motherboard in case of failure.
  • The CMOS CLR: allows to erase the BIOS parameters in order to return to the default ones.
  • The Q LED : 4 LEDs (CPU – DRAM – VGA – BOOT) which allow to diagnose the errors during the boot of the board. If one of them remains lit, it means that the component that corresponds to it has a problem.

Connectors :

The rear panel has the following elements. First of all the Clear CMOS, the BIOS Flashback as well as the antenna mounts for the dual band Wi-Fi. The board has an HDMI port, 2 USB 2.0, a USB 3.2 Gen 2 type-C, two USB 3.2 Gen 2, four USB 3.2 Gen 1, a LAN port (RJ45), 1 Optical S/PDIF Out and the various audio outputs. Finally, the audio part is provided by a Realtek ALC1220 chip.

To power all this little world, the card has a 24 pins connector and a 8 pins + 4 pins connector on the side of the power supply stages.

The PCB:

The PCB design of this NZXT N7 B650E model is still most likely outsourced by ASRock. We will research for the release of the article which model it refers to. Now, as we have always said, this is a very good choice considering the good reputation of ASRock.

The motherboard is based on a 16 + 2 +1 power supply (vcore/vddcr_soc/vdd). The CPU part consists of 16 phases with a RAA229620 controller with actually 8 phases placed in parallel.

The 16 mosfets are all ISL99390B of 90A! These are the same mosfets used by ASRock on some of its models. See you in a few days to discover the complete test of this NZXT N7 B650E and the Intel version with the NZXT N7 Z790.
Thanks to NZXT for making this sample available.
