Nesteq EECS Power Plus PSUs, 135mm Fan

Ultra
- Replaced by the Nesteq E2CS X-Strike Ultra-Quiet PSUs, 80PLUS

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 PSU, the PSU has sockets rather than fixed wires for powering the components installed in your PC, and what makes a modular PSU 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 PSU 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 PSUs 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 PSU. 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. 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 PSU fan by connecting it to a free 3-pin fan header on the motherboard. The PSU also features SVSS, Smart Voltage Stabilisation System. This provides a stable output voltage for the CPU and graphics card(s) with a tolerance of below 3%.
