NZXT E850 Digital Power Supply Review
Introduction and Features
NZXT recently introduced the E Series line of digital power supplies which is being offered in three sizes: 500W, 650W and 850W. The E Series power supplies are all modular, support 80 Plus Gold efficiency certification, and come backed by a 10-year warranty. We will be taking a detailed look at the NZXT E850 PSU in this review.
One of the more unique features offered by the NZXT E Series digital power supplies is support for NZXT’s CAM desktop monitoring and control software. This allows the end user to monitor various power supply parameters (voltages, power, temperature, etc., by rail) and provides control over current limit set points and fan speed profiles. An onboard DSP digital interface connects the E Series power supply to the PC via a USB link to the motherboard.
NZXT partnered with Seasonic as the OEM for the E Series; one of the most respected manufacturers in the industry. So as you might expect the NZXT E Series power supplies incorporate high-quality components like all Japanese made electrolytic capacitors 105°C and a 120mm FDB (Fluid Dynamic Bearing Fan).
The E Series power supplies are currently entering retail channels and should be available from your favorite online retailer by the end of July 2018. The MSRPs for the three E Series power supplies are:
• NZXT E500 - $119.99 USD
• NZXT E650 - $129.99 USD
• NZXT E850 - $149.99 USD
NZXT E Series PSU Key Features:
• 500W, 650W, and 850W continuous DC output at up to 50°C

Here is what NZXT has to say about their new E Series power supplies:
“The new E Series ATX power supplies from NZXT feature digital voltage and temperature monitoring for precise, real-time information about your PSU, including uptime, wattage by rail, and temperature. Store and track key data over time using CAM so you’ll always have an accurate picture of your PSU’s health. They are manufactured with top-quality components and backed by a 10-year warranty, delivering both peace of mind and clean, reliable power to your gaming system. NZXT E Series PSUs are available in 500W, 650W, and 850W configurations.
The power supply is an often overlooked yet essential component of every build. Modern power supplies have become increasingly stable over the years in delivering clean and reliable power to fulfill the power requirements of the modern PC. However, it is a key component not everyone understands.
CAM, NZXT’s desktop monitoring and control software, is about creating a centralized platform for users to master and take control of their hardware. When we set out to create the E Series, we wanted to make a power supply that is aligned with our goals for CAM and present information in the simplest and most efficient way, making it easy to digest.
Real-time power information for the CPU, GPU and other components are presented individually, allowing the user to see exactly how much power is drawn from key components. To achieve this, we’ve included a Texas Instrument UCD3138 Digital Signal Processor(DSP) that utilizes the Power Management Bus to provide CAM with very accurate data on the PSU power output by rail. Additionally, data about temperature and total power-on hours is also available.
Because the E Series PSUs have the capability to monitor power by connector, we provide the same protection as a multi-rail PSU, with true over-current protection for the 12V1, 12V2, and 12V3 connections. This added protection reduces the chance of electrical damage to the two of the most expensive components in a build--the CPU and the GPU.
Power supplies need to provide clean and reliable power. We worked with Seasonic to create a digital power supply that ensures this requirement is met. Our voltage regulation provides power to the 12V, 5V, and 3.3V rails within three percent.”
