I have a corsair cx750m and its fan is noticeably the loudest component in my system. Its a low-pitched humming sound with a little bit of a whining noise to it.How much quieter is the rm550x compared to the cx750m?
The RM550x is a lot quieter than the CX750M at 400W, which is roughly where you'd be sitting at with a 1080 Ti system. There are also other quiet options. one thing that worried me, if the CX750M is this loud, will the RM750i be just as loud, or should i be looking for 1000w+ units to keep the fan off?How efficient is the Corsair cx750m under light loads?
Using results from the previous page, we plotted a chart showing the CX750M's efficiency at low loads, and loads from 10 to 110 percent of its maximum-rated capacity. The CX750M's efficiency is low compared to Corsair's CX650M, and under light loads this model takes last place.How much noise does a power supply fan make?
Up to around 330W load the fan's noise stays low, but it quickly increases beyond that, and above 480W the noise exceeds 40 dB (A). Aris Mpitziopoulos is a Contributing Editor at Tom's Hardware US, covering PSUs.
