INTRODUCTION

   Higher electrical efficiency, cleaner and more stable electrical output and support for the latest PCIe 5.0 graphics cards by NVIDIA (+12VHPWR connectors) are the main reasons ATX 3.0 power supply units are gaining popularity in the market. Unfortunately, we haven't seen that many units in the market up until now (especially above 80 Plus Gold efficiency) but as previous ATX 2.5x models slowly get phased out of production this will of course change. MSI being one of the largest players in the PC market couldn't fall behind (obviously) and so they've already introduced not one but two ATX 3.0 lines and today with me i have the MPG A1000G PCIE5 model.

   MSI is a world leader in gaming, content creation, business & productivity and AIoT solutions. Bolstered by its cutting-edge R&D capabilities and customer-driven innovation, MSI has a wide-ranging global presence spanning over 120 countries. Its comprehensive lineup of laptops, graphics cards, monitors, motherboards, desktops, peripherals, servers, IPCs, robotic appliances, and vehicle infotainment and telematics systems are globally acclaimed. Committed to advancing user experiences through the finest product quality, intuitive user interface and design aesthetics, MSI is a leading brand that shapes the future of technology.

   The MSI MPG PCIE5 line includes 750/850/1000W output fully modular models all of which feature the 80 Plus Gold electrical certification (up to 90% electrical efficiency) along with active PFC and half bridge LLC topology for increased performance across the board. The MPG A1000G PCIE5 fully supports both the latest ATX 3.0 and PCIe Gen 5 specifications (2xCPU/3xGPU excursion tolerance) and sports a total of 7 PCIe 6+2 connectors, single 12VHPWR (600W) connector, single strong +12V rail (83.5A) capable of delivering the units’ entire power output (1000W) and a peak power output of no less than 1138W (although according to ATX 3.0 specs peak should now be up to 2KW for 100ms – this is not something I can try however). Secondary features include strong minor rails with a total output of 138W, low profile cables, high-speed FDB 135mm fan with zero fan mode (fan operates only when load surpasses 40%), 100% Japanese capacitors certified for use up to 105 degrees Celsius. As expected, the MPG A1000G PCIE5 is secured with a full array of electrical protections including over-current (OCP), over-voltage (OVP), under-voltage (UVP), short-circuit (SCP), over-temperature (OTP) and over-power (OPP). As with other similar models by the competition MSI covers the MPG A1000G PCIE5 with a very generous 10-year limited warranty.
