Evga 750w G3 eco mode on or off

On the back of the psu there is a eco mode switch should I put it on or off I ain't worried about cost of power consumption it's whichever is best efficiency?

off then eco is to limit the amount of power inputed in i believe... but i would say eco mode off is u dont care about the cost of power

i leave eco mode off on my g3. i think it keeps the psu cooler.

When ECO mode is enabled, the power supply fan will not spin until a specific temperature is reached. To enable ECO mode, there is a switch on the back of the power supply. With ECO mode enabled the fan should not run until the power supply hits 55c. If the temperature reaches or exceeds this threshold, the fan will turn on to prevent overheating.

you can test it out for yourself to see if you have similar results, but my experience is with eco enabled, when the fan does finally kick on under load it is faster and louder than if eco had been left off the entire time.

I leave it off on my GQ, the fan gets really loud when it kicks in.

It's quieter with the fan running normally.

no reason to keep it off. that person clearly had no diea what he was talking about. Omega posted the right text from evga website and the manual.

Doesnt make sense that a PSU limits its power...

Feel free to turn it on..it's the same with graphics cards, they turn off fan under 50c or 60c depends on gpu model.

Same thing here, I had this happen before and I completely decided to keep it off until I tried it again. This time I had it on because I could barely hear the fan and as soon as I launch a game and the GPU gets hit it goes VVROOOOOOOOMMMMMM and slowly fades away. Clearly the PSU is shooting way way up in temperature and as soon as it is kicked while hot it realizes its way too hot. It is never a gradual increase in fan speed.

I have an EVGA 750w and the eco switch does nothing to the power it just controls the fan. I have mine on and its fine. No fan boosting, no excess heat and its silent. I game with an RTX 2080 on a triple monitor setup, 32gb and four ssd's and psu does not stress at all.
