Cooler Master Silent Pro M2 1500W PSU Review

External Design

Cooler
Masters most powerful unit not only is a behemoth in terms of power but in
terms of physical size as well. The black chassis measures 220mm deep, much
longer than what the standard ATX design guide dictates, without counting the
extra depth required by the cables and connectors. Without a doubt, this power
supply requires an equally large case with plenty of room for a large power
supply. The 135mm fan is covered by a round grill with dual support braces.

The sides
of the power supply are covered by a plain black sticker with only the series
logo and power output of the unit printed on it.

As usual,
the sticker with the detailed electrical specifications of the power supply can
be found at the top side of the power supply. This sticker will only be visible
if the case has the power supply compartment situated below the motherboard
tray and uncovered.

The
partially modular Silent Pro M2 1500W unit has plenty of connectors hardwired
to the power supply but there are also eight modular cable connectors, three
for the PCIe devices and five for the Molex/SATA connectors. Strangely,
considering the massive power output of the unit, the number of SATA/Molex connectors
is extremely conservative. The 24-pin ATX connector, the 2 x 4+4 CPU connectors
and six PCIe connectors are hardwired, while the modular cables add another six
PCIe connectors, 12 SATA connectors, 5 Molex connectors and a single floppy
connector.

Naturally,
the front side of the Cooler Master Silent Pro M2 1500W unit is perforated,
with an on/off switch next to the C19 A/C receptacle. There is also a sticker
warning the user not to use this power supply if the wall outlet is not
specified for 16A @ 125VAC or 10A @ 250VAC. Actually, in a proper electrical
installation no irreversible damage would occur if this unit is plugged to an
outlet incapable of delivering that much current, only the circuit breaker of
the power line would disengage if the system ever came to need more current
than what the installations line could handle. On the other hand, there are
plenty of household and commercial electrical installations which do not adhere
to safety standards; therefore Cooler Master rightfully covered their backs in
case someone somewhere had the bright idea to use a 50A breaker on a line with
16 AWG wires.
