I've been running this power supply on my test machine for over
2-weeks now and I'm finally ready to give my verdict... Unlike the
majority of power supplies that are mass produced in the PC-market,
Cooler Master are one of the rare producers who continually
update their well designed products thanks to their vigorous testing and research.
This is not some reversed engineered power supply but rather a
powerful modern power supply for the latest PC hardware and
configurations for not just the tech head but also the computing
novice. With that said, Cooler Master also
supports the following models of the Silent Pro MII;
- Silent Pro M II 420 W
- Silent Pro M II 520 W
- Silent Pro M II 620 W
- Silent Pro M II 720 W
- Silent Pro M II 850 W
- Silent Pro M II 1000 W
For this review, Impulse Gamer tested
the 520W model, however depending on your need, some users may
choose the more powerful units.
More importantly, the Cooler Master
Silent Pro MII has the grunt behind it to run several graphic cards
and even the most powerful motherboard with their 8 cores. Another
feature is that the Cooler Master Silent Pro MII is extremely silent
so when your PC does start to become a little warm from playing the
latest Battlefield or Modern Warfare game, it has the technology to
ensure that the heat is evenly dispersed and your PC remains as cool as
According to Cooler Master, this product will last at least 100,000
hours of use and in order to back this statement, Cooler Master have
added a 5-year warranty to the power supply which is quite unheard
of but definitely a welcomed facet. For the techno purists, let's
have a gander at the features of the Cooler Master Silent Pro MII;
Copper-Aluminum Heat Sink
This slick CM design incorporates an expansive flat surface
area for superior heat conductivity out to the aero-dynamic
fins, therefore removing heat at an unprecedented rate.
135 mm Hydraulic Dynamic Bearing Fan for quieter operation
Single 12V Power Rail
Single 12 V Power Rail Tackling challenges from the most
power-intensive peripherals head on, this solitary 12 V
power rail provides ample power and strong resistance to any
overloading up to 40A.
Neatly arranged connectors on the rear plate connect to flat
internal cabling improve installment facility while allowing
for greater airflow through the PSU.
Proficiently prepared to provide a stable power source and
connectors for the latest ATX 12V v2.3 Intel processors.
Eco-friendly design: Erp Lot6 Ready!
A maximum 5Vsb current draw target in S5 off-mode of 0.1A
for its motherboards and needed to ensure the system will
consume < 1W in its off-mode
- Multiple updated connectors for all types of interfaces (PCIe,
- Double-Layer EMI Filter Dual protection from
- Multiple Protection Design (OVP/UVP/OPP/OTP/SCP)
- High reliability with an MBTF of at least 100,000 hours of
- Five Year Warranty.
you can see from the features, this power supply is no slouch when
it comes to features and benefits to the user. From Intel
compliance, superior dispersion of heat thanks to the copper
aluminium heat sink and aero dynamic fins, eco-friendly and my
favourite modularized cabling, this power supply has it all. I've
been building PC's for around 20 years and this is easily the
friendliest power supply that I've had the pleasure of playing with.
Everything is just so streamlined and more importantly, it has the
features to keep your PC cooler.
The installation of the SPM2 520W was a breeze on our test machine
thanks to the modular cabling design. This not only makes installing
your various cables onto your computer a breeze but ensures that
clutter is reduced and that the airflow inside the case is improved.
The product supports a variety of cabling options that include CPU
4+4 Pin (600mm) x1, M/B 24 Pin (550mm), PCIe 6+2 Pin (600mm) x2,
Peripheral 4 Pin + Floppy (400+100+100mm) x 6 and SATA
(400+100+100mm) x6. Cables have also been flattened and are longer
than other cables on different power supplies which increases to the ease of the installation.

must admit that uninstalling my old power supply was actually more
complicated than installing the new SPM2 520W. However once
installed and my PC turned on, the entire computer was extremely
silent thanks to the 135mm hydraulic bearing fan. Even on warm days
(30+ degrees), the power supply remained silent with a low
temperature and the only
loudness was from my graphics card while I played Deus Ex.
As the SPM2 520W is a "green design",
even when the unit is in standby mode, the power supply uses a very
minimal amount of power to keep the system alive. The Single 12V
power rail design is another highlight, especially for those
overclockers who want to get the most out of their systems or those
users of high-end graphic cards for their PC. This technology
basically prevents any overloading.
In the end, the Cooler Master Silent
Pro M2 is very powerful supply that ensures as much heat as possible
is kept out of your computer chassis. Any complaints? None
whatsoever! The only recommendations that I could make to the end
user is a large case (which makes installation easy) and if you have
the budget, a Cooler Master case. Best of all, the cost of this unit
is quite affordable and match that with a 5-year warranty and your
PC and future upgrades will be quite safe with this product.
