After the successful entry into the German market for PC power supplies at the end of 2015, Kolink is now working with the Core series and shows that particularly inexpensive power supplies are possible without the customer having to forego basic quality features. A Kolink-Core power supply provides everything that is really important, while less important features are consistently saved. So the Cores are technically solid, but still hardly more expensive than the all-but-no-name products.
For the entry-level series, Kolink uses, for example, the 80 Plus certificate, which guarantees efficiency of more than 80 percent from 20 percent utilization at 115 volts. In the European 230-volt network, all models of the Core Series meet the requirements of EU Regulation No. 617/2013. Since July 2014, this has presumably required a minimum efficiency of 82 to 85 percent for all power supplies used in complete PCs. Because the mandatory requirements for standby power consumption and standby efficiency are also met, Kolink core power supplies are therefore a cheap but right-safe choice for all integrators and system houses.
The fact that Kolink is familiar with its products of the entry-level class is also evident in the equipment as well as in the connections. The top model of the Core 80 Plus series delivers a maximum power output of 850 watts and uses top-class technology: while in the primary range a double-forward circuit is used, the manufacturer uses secondary DC-DC technology with independent voltage segregation. Both the efficiency and the precision of the power supply benefit, especially in the case of asymmetrical loads.
The 850-watt model offered here has a 4 + 4-pin EPS12V connector for the processor as well as a total of four 6 + 2-pin connectors for the graphics card in addition to the 20 + 4-pin ATX connector for the mainboard . Five SATA and three Molex connectors are available for the other components. The Kolink Core 850 Watt can therefore prove its performance at any time in real systems. Even gaming systems with SLI and Crossfire tapes from high-end graphics cards are easily supplied by this low-cost power supply.
It is important to note that Kolink - unfortunately as part of the minority of the power supply brands - carries out product design as well as the final quality control completely in Europe before delivery to specialist retailers, system integrators and end customers. Despite the aggressive prices, these are full-fledged retail products for the demands of European customers, whose quality is ensured by the manufacturers at all times. A power supply must ultimately function reliably in the first place, so that the computer runs smoothly.
Saving on the other hand is something that many users in this price class do not value: That Kolink supplies all power supplies without a cold-wire cable protects the environment and saves costs, while most potential buyers at home already have matching cables. Kolink also has a purist style, the cable strings are held together by convenient cable ties instead of elaborate sleeves. The surface is simply black lacquered, so the power supply in the PC hardly notice. In short, if you only have a tight budget, the core power supply is currently the best choice.
