Test Methodology / Report

goldfries.com does not have industrial grade power supply testing tools, therefore the approach for the PSU test is from a consumer angle. This means the PSU will be pushed to operational limit based on components that are available in the market. The key components used for power draw are the CPU (choice of processor), the GPU (graphic card setup) and other components like fans and drives.

The stress test is performed by stressing the 12V rails with 80% to 90% load, and run for at least 6 hours which is a lot more stress than what the average consumer would place on a power supply over the course of months or even years.

The AeroCool KCAS 850M delivers 840 Watts over the 12V rails but the maxed out wall-draw for this test comes to about 600w, not exactly stressing the PSU but the setup is already quite demanding and the PSU lasted through the 6 hours of torture (ok maybe not) with no issues. Voltage seems pretty stable too.

The Verdict

The AeroCool KCAS 850M Semi-Modular Power Supply retails at RM 449 and delivers the power and should be of no issue handling any system thrown at it.

I don’t think it’s a bad product but I have problem recommending it, simply because Seasonic’s M12II 750W is available at a similar price range but as you know, they’re quite far apart when it comes to their reputation in power delivery.
