My IT consultants then went in a test at the prestigious PC tester PC experience in Lübeck attention: the recommended power supply Seasonic M12II-520 was, for 54 - to have (December, 2013). I ordered two pieces.
With regard to continuous operation of course I can not say much, but the quality is impressive: Externally simple, as it should be, but plenty of very good cable in separaterm bag, practically in the cables is no difference to a 150, -Euro power supply, the I had bought for the establishment of a new PC three months ago. In PSU itself durchwg installed 105 ° C capacitors, as well as numerous safety systems.
The power supply unit has a large, very slow running fan - which you can hear absolutely nothing; I have the PC just extra-opened again to make sure that the fan noise that you hear when you put on the ear on the fan guard of the power supply directly comes from the PCU fan, but not from the power supply.
To point security systems it is in PC Experience:
"5. Protection:
Current quality power supplies have numerous safeguards to protect our built expensive hardware from damage caused by short circuits, voltage spikes and different kind of irritation:
- OCP (Over Current Protection) - protection against current peaks.
- OTP (Over Temperature Protection) - overheating protection.
- OVP (Over Voltage Protection) - overvoltage protection.
- OPP (Over Power Protection) - overload protection.
- UVP (Under Voltage Protection) - undervoltage protection.
- SCP (Short Circuit Protection) - Protection against short circuits.
- NLO (No Load operation) - Protection against no-load operations.
Should your envisaged power supplies do not include the vast majority of these protections, you should take from a distance purchase, because these power supplies tear in corresponding problems often connected hardware with the same in the abyss ...! "
In this context, I would like you to consider that in a cheap power supply when the same four or five external drives are connected via USB, these plates can be shot out from the power supply of, up to complete data loss (is my IT consultant a few days happened). With a good power supply with zahlr. Protection mechanisms (see above) is not to be expected.
From me strong buy recommendation!
