Cooler Master Silent Pro M500 500W Modular PSU Review

The Cooler Master Silent Pro M500 has a good price for a 500 Watt power supply unit.

The supply of the Coolermaster 500 Watt PSU …

In this box comes the Cooler Master power supply with accessories.

Here is a picture of the box after removing the Silent ProM 500W cover.

Now it is possible to flap both parts of the box apart to reach the content of the box – very nice idea.

That is contained in the box …

In the following picture, one can see the black 150x150x85mm power supply with the attached 47cm long 20-pole ATX and/or 24-Pol ATX 2.2 cable for the motherboard current supply and the attached 56cm long 12V CPU cable with 2x 4-pin plugs. This is enough for a modular PSU, because the rest of the cables should be modular, so this is optimal solved. However, the ATX cable could be too short for some Fullsize Tower systems, so one better remeasure all lenghts inside of the case, before buying the power supply.

In the scope of delivery are a lot of cables and assembly material, as shown in the following picture:

2x 45cm PCI-E cables with 6+2-pin plugs 2x 75cm cables with 3 SATA connectors (45+15+15cm) 1x 75cm cable with 3 molex plugs (45+15+15cm) 1x 75cm cable with 2 molex plugs and one floppy connector (45+15+15cm) 1x 220V power cable

The cables are exemplary finished and very flat, so they are very easy to install in most enclosures. All connections are well made and offer a safe contact.

Furthermore contained are some screws, two Cooler Master SiliconPad antivibration pads, a warranty card (5 years), a CD and a folding sheet, which contains a pictured building instruction, power supply pin allocations, warning references and the disposal references. Don’t be surprised at the CDROM – the CD doesn’t contain any drivers, but once again the manual.
