• Full modular cable design
• Flat cable equipment
• 10-year warranty
• 80 Plus Gold certified for high efficiency
• 100% all Japanese 105oC capacitor
• Active PFC design
• Industrial level protection with OVP,OCP,OPP,OTP, SCP,UVP
• LLC Half Bridge Topology with DC-DC module design

80 PLUS GOLD CERTIFIED
The efficiency of your power supply directly influences your system's performance and your power consumption. The 80 PLUS Gold certification promises lower energy consumption and higher efficiency.

GPU SUPPORT FOR ALL
The MPG gaming power supply can support the NVIDIA GeForce RTXâ„¢ 30/20 Series and AMD GPUs. Prepared for the highest of requirements, the MPG power supply's IO supports can support different and versatile ways of connection according to the power connector design of different graphics cards.

Aiming for unwavering product quality and performance stability, the MPG gaming power supply comes with 100% Japanese 105° C capacitors and solid capacitors.

ONLY WHAT YOU NEED
Organizing cables is often the most bothersome part of building a PC. With the MPG gaming power supply's fully modular design, it means that only the connectors required by the build need to be used, significantly reducing cable clutter and simplifying the system's overall build.

ALLOY COPPER CONNECTOR TERMINALS
The MPG gaming power supply's CPU, VGA, and MB connectors utilize alloy copper terminals that can withstand higher current ratings than traditional phosphor bronze cable terminals.

Specifications

Package

MSI MPG A850GF comes in a securely packaged box with PSU graphics, Model name and features highlights on front and the back of the box.

Inside the box

Box includes MSI MPG A850GF PSU with cable- pouch containing Power cable PSU mounting screws and User manual

Looks

MSI has done a great effort on aesthetics of the PSU. With a matte black paint and slight touch of white along with full black flat cables, gives the PSU a premium rich feel.

Inside

MSI uses 140mm ONG HUA fan (HA1425M12F) with a 12 V and 0.36 A rating inside the MSI MPG A850GF power supply.

The build quality of MSI MPG A850GF power supply board is very high and uses all Japanese capacitors in the primary and secondary stage.

Testing

Test system configuration -

The MSI MPG A850GF PSU handled above high end system very comfortability. And we were easily able to overclock Intel Core i9 10900K upto 5.1GHz all core stable using this PSU.

Custom made DC Active dummy load PSU tester.

Load Test

To test the PSU on my Active load test, I have manually increased the load in Amps on 12v first rail, 12v second rail, 5v and 3.3v rail to simulate 100%, 80% 50% and 20% load. Since this PSU is having only single 12v rail, so divided the load in half on both 12v loads on my tester.

5V stand-by and -12V supply was left at a constant 0.5amp load throughout the test run.

Maximum theoretical load handling capacity of my tester is somewhat around 1500W, but due to MOSFETs safe operating area (SOA) characteristics and thermal load handling capacity of the heatsinks, this tester can handle Max 1300W.. For safety reasons I have also installed a thermal controller which turn OFF the attached PSU if temperature exceeds SOA specifications.

During test the PSU ran smoothly up to 910W of load, when tried to pull more the PSU turned itself OFF showing the proper working of Overload protection.

Pros

• 100% all Japanese capacitors
• 10 years warranty
• Fully Modular Black Cables
• 80 Plus Gold certified
• High build quality

Cons

• Nil

Conclusion

MSI MPG A850GF PSU in our test showed good voltage stability and low ripple with giving close to 80 PLUS GOLD efficiency. PSU fan was very quite at low and modest load, and was little noticeable under full load too. The protection circuit OCP worked perfect and PSU turned itself off when tried to pull over 910 watts.

Finally at the price tag of Rs.9750 (approx.) the new MSI MPG A850GF PSU is nice price to performance units satisfying most of the current gaming builds. With full flat black cables, all Japanese capacitors and a 10 year warranty MSI MPG A850GF is best option for high-end gamers and work pc builder and makes it worthy of our PC TeK Reviews Choice Award for PSUs.
