The E2CS X-Strike 850W Ultra-Quiet PSU features everything it's predecessor had (including the excellent EECS cabling system), but you would expect that. What you may not expect is a built-in PSU tester! That's right every version of the X-Strike is supplied with this excellent feature! 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 - 80PLUS certified 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 88%, 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.

Power Monitoring Panel

The Power Monitoring Panel on each E2CS X-Strike power supply indicates if there are problems with the most important power output rails. If there should be a power failure on one of the +12V, +5V, +3.3V or +5Vsb rails, the green LED will be off.

Included

in the package is an adaptor, which can be plugged to test the power supply even without connecting it to a motherboard.

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%.
