| NesteQ ECS7001
700W ATX power supply
NesteQ is a fairly new player in the computer components market. Based in Germany,
NesteQ a series of new power supplies that claim to have high efficiency and
low operating noise - features well appreciated in the realm of quiet computers.
One of the ECS7001's main features is called E2CS, or Enhanced Easy
Connecting System. In other words, it's a modular PSU. However, they've gone
about the cables in a different manner than all others manufacturers. Instead
of using different cables for different lengths, they provide a multitude of
shorter cables, each with their own specific function. We'll describe this in
more detail later.
We've seen other "high-end" PSUs that are able to keep quiet, the Enermax
Modu82+ 625, for example, as well as the monstrous Zalman
ZM1000P. We'll see if NesteQ can keep up with the big boys or the silent
leaders of the PSU world. The ECS 7001 sample came from Acoustic
PC, a US online shop based in Florida. The company specializes in low noise
A fairly standard looking black box.

| FEATURE & BRIEF
|| Our comment
| Power Plus Connection
The PCI-Express, EPS and P4 Connectors have a +12V single Rail Connection.
The peripheral components like HDD, Fan or DVD-drive are using the divided
+12V/18A Rail which is more safety and comfortable
| An unusual idea, and unnecessary in
most systems. It also explains why the system is not UL Certified.
| Enhanced Easy Connecting System
Extended cable parts and HDD/FDD-connectors can be jointed up to the desired
length and the required facility.
| A nice touch. Could help significantly
with cleaning up cable clutter.
| Smart Fan Controlling System
With FM function, RPM (fan speed) of the embedded 13.5cm silent cooling
fan can be monitored by BIOS.
| Ok, but this doesn't tell us much about
how this fan controller is better than the rest.
| Erogonomic Cable Connection Design
The cables are positioned out at the same side where the facilities are
| A nice idea, but couldn't a few zip
ties achieve the same thing?
| Smart Voltage Stabilization System
The output voltage tolerance for CPU and graphic card is kept stable under
| This would help keep the PSU within
the ATX specifications.
| High Efficiency of 86%
|| A high claim. Interestingly, while the
box is imprinted with the words "80 Plus", the ECS 7001 is not
Plus certified model. Three smaller models in the NesteQ lineup
are 80 Plus certified, which raises the question of why this one
isn't on the list. The fact that it is the highest rated model gives us
a clue. If the platform (including heatsinks) is the same for all models,
then decreased efficiency at high load due to higher component temperatures
could be a factor. It may not meet the 80% at full rated power requirement.
| 36 months Warranty
|| It's nice to know we're covered.
The label really tells us all we need to know. A couple of observations:
