MSI MPG GF A850GF

Efficiency - 90%

MSI MPG GF is a powerful 850W AA power supply with 80 Plus Gold certification, 90% efficiency, detachable modular wires, comprehensive protection system and a limited 10-year manufacturer's warranty. Given that MSI has been harnessing the market for second-tier components (mice, monitors, etc.) for quite some time, they have to compensate for their delay with affordable prices and some features that competing solutions with an identical price tag cannot offer.

High-quality circuitry

Among the main advantages of the GF A850GF model, the manufacturer highlights the use of Japanese high-temperature capacitors, an efficient fan with a diameter of 140 mm and all the necessary protection measures (against short circuit and overheating, over and under voltage, overcurrent and power). All available 850 W are available to power the +12VDC main bus, there is no channel separation, which allows using this PSU in fairly powerful systems with one top-end video card or two mid-range GPUs.

Increase in noise with increasing load

At the same time, the cost of the model in most stores does not exceed $140, which makes it one of the most affordable solutions of this level that can be found in retail. The main competitors in the same weight category are Chieftec Polaris, Gigabyte P850GM and be quiet! System Power 10. Perhaps the only negative of the device is its disproportionate volume, which, apparently, is associated with the use of a mesh grille. At a load in the region of 500-550 W, the MSI MPG GF operates quieter than water, but as the voltage increases, the noise level grows disproportionately: at a load of around 80% it becomes noisy, at 95% it is quite loud.
