The SHA M Bronze Series is a line of PC power supplies with a modular connector system, meeting all “80 PLUS Bronze” certification requirements: It reaches an efficiency of 85% at a 50% load, and an efficiency of 82% at a 20% and 100% load.  
 
In addition to the 20+4 pin mainboard connector and the additional mainboard power supply (4+4 pin), both of which are firmly soldered to the circuit board of the power supply, the SHA Bronze power supplies offer a total of six connectors for the modular cable, through which the power supply can be equipped with a maximum of two PCIe (6 and 6+2 pin), six SATA and seven peripherals ports plus a floppy connect.
The use of those cables, which are really needed for the integrated hardware, optimize airflow within the case and contributes directly to a more effective cooling to heat sensitive hardware.
 
The SHA M Bronze Power Supplies offer two separate 12-Volt rails, which safely and reliably supply power to the connected components, and are cooled by a quiet 120 mm fan. They are available in 350, 450 and 550 Watts.
 
Features:

• ATX 12 V v.2.3:
  Supports the latest Intel and AMD processor based systems.
• 80 plus Bronze:
  This power supply unit complies with the requirements of the "80 PLUS bronze" certification, providing an efficiency of 85% under 50% load and 82% efficiency under 20% and 100% load.
• This PSU provides a modular cable system. Thus only the required cables need to be connected.
• Separate 12 V rails guarantee a stable power supply for all components.
• Active PFC function:
  This power supply operates with active power factor correction (PFC).
• Temperature controlled 120 mm fan:
  The installed 120 mm fan provides a considerably higher airflow with lower rpm, thus reducing the operating noise effectively.
• PCIe connectors:
  This power supply unit is equipped with one 6-pin and one 6+2-pin PCIe connector.
• Dimensions: 150 x 140 x 86 mm (L x W x H)

Protective functions:

• Short circuit protection:
  The power supply is designed with a short circuit protection to prevent damage of the power supply components. Main power will be shut down when a short circuit occurs. The PSU will return to normal after the short circuit has been removed and the main power switch has been turned off and back on again, with a minimum cycle pause of 2 seconds.
• Over voltage protection: The power supply provides a latch mode against over voltage, as defined below:

	Minimum	Nominal	Maximum	Unit
+12 V	13.4	15	15.6	V
+5 V	5.74	6.3	7	V
+3.3 V	3.76	4.2	4.3	V

• Over power protection: The power supply will switch off, when the total output power exceeds 385 W (SHA350M), 495 W (SHA450M) or 605 W (SHA550M).

Note:
The pre-installed 120 mm fan is temperature controlled and only starts spinning once a certain temperature limit is breached. As long as this limit is not exceeded (e.g. after installing the PSU), the fan will not begin to cool.
