Nesteq’s newest power supply, the EECS series, features a cabling system never before seen on a PSU.
EECS - Enhanced Easy Connection System
EECS, short for Enhanced Easy Connection System, is the next evolution of the modular power supply. Just like an “ordinary” modular power supply, the power supply has sockets rather than fixed wires for powering the components installed in your PC, and what makes a modular power supply so great is that you only need to connect the cables you require for powering the system. However, Nesteq’s EECS PSUs take this one step further by allowing you to connect different power connectors on the same cable rather than using two separate cables. For example, the image below shows one cable from the EECS PSU supplying power to 2 x 4-pin Molex, 2 x SATA and 1 x floppy device. A non-EECS modular power supply would require at least two cables to provide power to these devices. This feature further reduces the amount of cables used inside the system, which makes things nice and tidy!
Low noise level and high efficiency
As with all the power supplies we have available, the EECS series are extremely quiet. In fact we think these are one of the quietest ranges of fanned power supplies that we currently stock. Their noise level is reduced by Nesteq’s choice of 135mm fan and the fact that they have designed their power supplies with such a high efficiency. With a maximum efficiency of 86%, less waste heat is generated resulting in a cooler-running power supply. This in turn means the fan does not need to spin very fast which means lower noise levels! Nesteq claim that in normal operation the fan will not exceed 19dBA, with the maximum noise level being only 25dBA. Our tests do confirm this, we are very impressed with the lack of noise it produced.
Other features
Other features include Smart Fan Controlling System (SFCS) which allows you to monitor the fan speed of the power supply fan by connecting it to a free 3-pin fan header on the motherboard. The power supply also features SVSS, Smart Voltage Stabilization System. This provides a stable output voltage for the CPU and graphics card(s) with a tolerance of below 3%.
