Kolink Classic Power 400 W Review


We would like to thank Kolink for supplying the review sample.

Kolink is a Caseking house brand well known for its high bang for the buck products. The Kolink Classic Power PSU line includes four members with capacities ranging from 400 W to 700 W. All of these have fixed cables and come without power cords to keep the cost as low as possible. OEMs tend to charge a lot for power cords, which makes removing them from the bundle to cut the final price by a euro or two a good idea. For a power supply like the Classic Power 400, sold for a mere €40, two euros are a lot.

The Classic Power 400 is a power supply for mainstream PCs with integrated graphics or dedicated graphics cards with low power consumption. Interesting is that it uses DC-DC converters to generate the minor rails, which is usually not the case in this price range. Another interesting fact is that its model number shows the peak power it can deliver for a short period of time, not its maximum continuous power output, which is 50 W lower, actually restricted to 350 W.

The provided warranty is three years long, which is enough for a €40 power supply, and in terms of efficiency, the PSU is 80 PLUS Bronze and Cybenetics Silver certified. All of the above sounds too good to be true, so I am anxious to see where the catch is here as it is a PSU for €40 with DC-DC converters and 80 PLUS Bronze/Silver efficiency. Alright, it doesn’t have an AC power cord, but who cares? Most users have several lying around, so why pay extra for it.
