MSI MPG A1000G/A850G/A750G PCIE5
So, as we talked about, these new power supplies support PCIE5, ATX 3.0 compatible, 12VHPWR, and 80 Plus Gold Certified. Other notable features across the entire line are that they are a Single-Railed design, support 0% RPM fan mode, have a fluid dynamic bearing fan, 100% Japanese 105c Capacitors, are all a Full-Modular Design, and are in a compact size, even the 1000G. Let us discuss each of these things below.
The MPG 1000G PCIE5, MPG A850G PCIE5, and MPG A750G PCIE5 can hold up to 2x total power excursion and 3x GPU power excursion. What this means is that the GPU power can exceed that 3x power excursion we talked about that the PCI SIG defines, but it does not just stop there. The power supply can also deal with a 2x power excursion on all the other components combined as well, think CPU and other high-powered devices. That extends its ability to deal with total system power spikes in microseconds.
The MPG 1000G PCIE5, MPG A850G PCIE5, and MPG A750G PCIE5 have the full implementation and support of a native 16-pin 12VHPWR connector. It connects to the power supply side with the 16-pin connector, which includes data sense pins, and on the other end is also a 16-pin connector with data sense pins. On the MPG 1000G PCIE5 and MPG A850G PCIE5, it can deliver up to 600W of power, but on the MPG A750G PCIE5 it will only deliver up to 450W because the overall capacity of the PSU is lower. This new connector will work on upcoming video cards, but it also works on the GeForce RTX 30 series, despite the video cards themselves not having the 4 data sense pins (12-pins total) on the video cards.
The power supplies are all 80 Plus Gold Certified. The power supplies support a 0 RPM fan mode which will stop the fan’s operation when TDP is below 40%. This mode is on by default, but you can turn it off if you always want the fan on. All three power supplies utilize a fluid dynamic bearing fan to increase the life span and maintain low noise levels.
Another feature of the MPG A1000G PCIE5, MPG A850G PCIE5, and MPG A750G PCIE5 is that these are all a single rail power supply design. That means it uses a complete single rail of power across the 12V rail. If you look at the specs at the bottom, you will notice the full capacity of each one supplied on the 12V rail. The power supplies also use 100% Japanese 105c capacitors and solid capacitors.
All three power supplies are fully modular. These power supplies also have a compact design that is smaller than typical PSUs on the market. In the picture above you can see that all three power supplies measure just 5.9 inches in length and 3.4 inches in height, yes even the MPG A1000G PCIE5.
Multiple protection mechanisms are in place: OCP (Over Current Protection), OTP (Over Temperature Protection), OVP (Over Voltage Protection), OPP (Over Power Protection), UVP (Under Voltage Protection), and SCP (Short Circuit Protection).
The MPG A1000G PCIE5 is a 1000W power supply and 80 Plus Gold up to 90%, fan size is 135mm. The power supply measures 5.9 inches in depth and width and 3.4 inches in height. As you can see from the label it supports 1000W across the +12V rail at 83.5A and 120W across the +5V and +3.3V.
