INTRODUCTION

    Every system, from minimalist desktops to high‑draw gaming rigs, ultimately leans on the PSU to keep voltages steady and thermals predictable. It’s the one part of a PC that never gets to rest, quietly managing load shifts and protecting hardware from electrical surprises. That constant, behind‑the‑scenes workload is what makes the PSU feel less like a component and more like the system’s electrical infrastructure, the layer that determines whether everything above it operates smoothly or struggles against instability. EINAREX’s NEXUS L1 850W steps into that role with a straightforward, regulation‑focused design.

    At EINAREX, we imagine a future where our innovations seamlessly integrate into the fabric of everyday life, empowering users to achieve more than they thought possible. Picture a world where technology not only understands your needs but anticipates them, where the boundaries between the digital and physical realms blur to create a harmonious and enriching experience. Our vision is not just about pushing technological limits; it’s about forging connections, fostering creativity, and ultimately contributing to a global community that thrives on the possibilities unlocked by EINAREX’s forward-thinking approach. Every EINAREX product is the result of careful research and development, ensuring that it not only meets present demands, but also adapting to future trends. Every product we bring to market, will guarantee our users exciting experiences.

    The NEXUS L1 line of power supply units by EINAREX includes 3 models (750/850/1000W) all of which are fully modular, Cybenetics Gold certified (over 80% electrical efficiency) and ATX 3.1 & PCIe 5.1 compliant. The 850W output model which I have here with me today is equipped with a single 12V-2X6 power connector (450W), four 6+2 pin PCIe power connectors, single strong +12V rail (70.5A) capable of delivering roughly 98% of the units’ total power output (846W) and a peak power output of no less than 972W (peak should now be up to around 1.94KW for up to 100ms - once again however this is not something I can test). It also features full-bridge LLC with DC-to-DC design topology, active PFC and a full 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 in rush (SIP). As for warranty EINAREX covers the entire Core GX line with a very generous 10-year limited one.
