Over Power Protection and Max Wattage
Power supplies often quote as having various protection mechanisms such and the most important of these is Over Power Protection. In our testing we crank up the power draw until the power supply either shuts down (meaning the OPP mechanism is present and working) or blows up (meaning it is either not present or not working). We then note the maximum power consumption before the power supply shut down (or blew up).
OPP was triggered 138W above this unit’s rated capacity: Thermaltake rate this unit for 660W peak output and we can see that is indeed the case.
There’s no reason to state “Fan speed lower is better” on the chart because that is only a subjective opinion while factually speaking, higher is better for the PSU itself to reduce temperature except in this particular case that low quality Yate Loon fan will probably wear out its sleeve bearing before the life of the PSU is otherwise exhausted.
Hello. I am looking into buying a new PSU for my computer. I will upgrade to the AMD R7-370, my CPU is AMD FX4300. I want to buy the Thermaltake Tt Toughpower DPS G 550W ATX23 (here is the link http://hardware.nl/thermaltake/ps-tpg-0550dpcgeu-g.html ), but it seems to be different from the one you are reviewing. Is this a really different line? The one to which I linked has a 140mm ventilator, so it should be quieter. But the one I see in the image has a 120mm.
Yeah, it seems so. Strange Google gives this link when I am looking for a different Thermaltake.
