The Corsair RM850e isn't reaching zero RPM.
Hello everyone, I am running into a strange issue. I upgraded my GPU to a 3080 TI and had to purchase a new PSU. I got the Corsair RM850e and on the back of the box it advertises zero-fan operation so long as less than 170 watts are being drawn. At idle though, the PSU fan still spins. Here is what is in my machine: - R5 5600 with Noctua NH-U12S Redux fan (120mm) - 3080 TI founders edition - 2 basic NZXT fans running somewhere between 40-65% - TP-Link wifi card - ZERO RGB According to the Nvdia performance overlay, my GPU is "sipping" about 30 watts at idle which I would imagine is the most power hungry thing given the 5600 has a TDP of 65W. I don't see what could be drawing enough power to justify the PSU fan kicking on unless the PSU is defective? The temperature in my room is about 75 F. Any advice?
Review system details using HWinfo64. It provides a comprehensive overview of hardware temperatures, speeds, and wattage usage. Operating at around 170 watts is manageable, particularly with background applications active. The fan exists to maintain the PSU’s temperature; if airflow is limited, the PSU may run the fan just to stay cool. I should note that even a basic motherboard typically draws about 80 watts, while an Nvidia RTX 3060 can reach up to 170 watts, and idle power consumption can differ significantly. I wouldn’t be surprised if the PSU is functioning correctly.
I had to sign up because the comment above was completely inaccurate. I'm facing a similar problem—I purchased a Corsair PSU and the ZeroRPM setting isn't functioning (it's a different model, TX series). Achieving 170W with this configuration definitely requires some system load. The motherboard itself can't draw more than 80W, which is far beyond what even a Ryzen 5600X would consume without additional cooling. I have a 5600X and a 3080FE that only use about 35-65W when idle or under light usage.
