In addition to numerous low-priced yet highly regarded chassis and an extensive range of accessories, the Kolink brand already offers long power supplies of various performance classes. After the successful entry into the European 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 delivers 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 low-cost but right-safe choice for all integrators and system houses. The fact that Kolink is familiar with its entry-level products is also evident in the equipment with connections. The 500-watt model for office computers and economical multimedia systems offered here already has a 4 + 4-pin EPS12V connector for the processor as well as a 6-pin ATX connector for the mainboard + 2-pin connector for graphics card. Four SATA and two Molex connectors are available for the other components. The Kolink Core 400 Watt can therefore prove its performance at any time in real systems. Even gaming systems with mid-range and performance graphics cards are supplied without problems. It is also worth noting that Kolink - unfortunately as part of the min
