80 PLUS Gold Certified Digital PSUs feature PMBus Monitoring

July 17, 2018 by Paul Shepard

NZXT has added a new line of digital ATX PSUs designed to provide PC builders with real-time power monitoring and control. The E Series lineup includes 500W, 650W, and 850W models, all 80 PLUS Gold certified. For these PSUs, NZXT partnered with Seasonic and worked with them to enhance their Focus+ Gold platform and PMBus architecture, adding a Texas Instruments DSP and USB connectivity.

“The PSU is a critical part of your PC. Our goal for creating a smarter PC capable of automatically responding to the demands of the application--whether you are browsing the web, drafting email, or playing your favorite game--includes adding control and monitoring to devices that are integral to the system,” said Johnny Hou, founder and CEO of NZXT.

“Our E Series PSUs are another step in completing this vision. You can track the performance of the PSU in real time, monitor temperature and total power-on hours, and even enable multi-rail OCP for additional protection of key components using CAM--our innovative software solution at the heart of our smart PC,” Hou continued.

The E Series uses a digital signal processor (DSP) to provide real-time wattage indicators for the three 12V rails, along with total uptime and internal temperature. Compare CPU and GPU power draw to their rated TDP and track historical data using CAM.

In addition to providing high-precision monitoring, the onboard DSP lets users enable independent over-current protection (OCP) for the 12V output to the motherboard, CPU, and GPU, providing even better protection for expensive components.

NZXT E Series PSUs key features:

  • Active monitoring for the 12V, 5V, and 3.3V rails
  • Total power-on time tracking enabled using the embedded real-time clock (RTC)
  • Digital multi-rail over-current protection (OCP) for all three 12V outputs, with adjustable thresholds for the 12V CPU (4+4 pin) and GPU (6+2 pin PCIe) connections
  • Japanese capacitors rated at 105°C
  • 80 PLUS Gold certification
  • Fully modular design means you use only the cables you need
  • 10-year Warranty and NZXT Service and Support

All 80 PLUS Gold certified E Series PSUs are built using Japanese capacitors, rated to 105° C, providing long-term durability and reliability, and are backed by a 10-year limited warranty.

When powering loads under 100W total, the 0dB Mode provides fully silent operation. Using CAM, users can optimize the fan curve to suit the specific system configuration or choose between the Silent, Performance, or Fixed preset modes.

E Series PSUs support single- or multi-GPU builds and the fully modular design means using just the connections needed for the specific configuration build, reducing cable clutter and simplifying system building and expansion.
