Specifications

Package

MSI MPG A1000G PCIE5 PSU 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 A1000G PCIE5 with modular cables, 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 unique fan grill and aluminum product stickers, gives the PSU a premium feel.

Inside

MSI MPG A1000G PCIE5 power supply offers very good PCB build quality with all Nippon Chemi-Con capacitors with 105C rating.

Testing

Test system configuration -

Above high-power PC configuration is used to put the PSU in a real-world power handling scenario by running different GPU and CPU benchmarks.
And MSI MPG A1000G PCIE5 power supply easily handled many runs of high power consumption benchmarks.

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 close to 1140W of load, when tried to pull more the PSU turned itself OFF showing the proper working of Overload protection .

Pros

• PCIe 5.0 ready
• ATX 3.0 Compatible
• Compact design
• 80 Plus Gold certified
• Fully modular
• 10 years warranty
• 0 RPM Fan mode

Cons

• Nil
