We’ve
always had a fondness for power supplies that offer variety when it comes to
cabling, such as cables of different lengths and lots of options for SATA and
Molex connectors. So when we saw the unprecedented assortment of cable options
that be quiet! includes with the partially modular Dark
Power Pro 10 750W, we geeked out a little.
While Be Quiet! Has been a
leading provider of power supplies in Germany for several years,
now it aims to target the North American market with high quality products.
For
instance, this PSU comes with three cables for CPU power, each with a distinct
connector(s) – a 4-pin, a 4+4-pin, and one with both an 8-pin and 4+4-pin.
You’ll only be able to connect one of the CPU power cables, but we appreciate
that be quiet! gives you the flexibility to adapt the
power supply to different builds. Similar mix-and-match options are available
with the PCI-E, SATA, and Molex cables. For instance, there is a cable that
offers a single SATA connector and one with a single Molex connector, as well
as a cable that mixes SATA and Molex connectors. This way, you’ll be able to
select the modular cables that are ideal for your build.
Be quiet! designs this 750W power supply with four 12V rails (two 25A,
two 30A). You’re not tied to the four-rail setup, though, because the Dark
Power Pro 10 has a physical switch that mounts to your case’s rear expansion
slots and lets the PSU function as a 62A single-rail power supply. be quiet! indicates that the
single-rail setup is ideal for overclockers. The
multi-rail setup is safer, however, because each 12V rail is secured with its
own overcurrent protection.

Be Quiet! touts the
“legendary silence” of the product line,
which aside from the marketing speech is no overstatement.
The Dark
Power Pro 10 offers six 6+2-pin PCI-E connectors, which is enough to wire a
triple SLI or CrossFire setup. Those with high-end
GPUs will first need to consider their cards’ power requirements, though. be quiet! tells us that the Dark
Power Pro 10 750W can comfortably handle two top-of- the-line GPUs. A good
number of SATA (nine) and Molex (nine) connectors are available, too.
The Dark
Power Pro 10 750W offers a number of features aimed at reducing system noise.
First, its 135mm SilentWings PWM fan uses an advanced
fluid dynamic bearing that should lower operating noise. The SilentWings fan is also decoupled from the PSU body,
resulting in less vibration. This PSU can also control the speed of four other
system fans based on your case’s internal temperature.
We
benchmarked the Dark Power Pro 10 750W in its default four-rail configuration
using a test system equipped with an Intel Core i7-4960X, a GIGABYTE
GA-X79-UP4, and a GIGABYTE GeForce GTX 780 GHz Edition (GV- N780GHZ-3DG). We
took our power measurements when the system was simultaneously running POV-Ray
Beta 3.7 (stresses all CPU cores) and Aliens vs. Predator (stresses GPU). The
Dark Power Pro 10 displayed a maximum wattage of 418W at a power factor of
.992. The power factor is one of the higher we’ve seen in our testing, and the
PSU was able to reproduce the impressive numbers each time we re-ran the stress
tests.
As well as eight molex
and nine SATA connectors,
a total of seven PCIe connectors are provided, more
than any other on test.
The Dark
Power Pro 10 750W delivered impressive results in our benchmark tests. Best of
all, be quiet! provides you with a ton of cabling
options. A smart fan control system tops it all off. This is a PSU that screams quality
