Power Supply RTX 2080 ti with a SF600?

[jtmsrl]

I know the RTX 2080 Ti’s recommended PSU is 650w according to nvidia website, although not minimum. Is there someone running this with a 600w SFX gold rated PSU?

Other components:
i7-9700k
Noctua NHU9S + extra fan
3 Noctua case fan
1 SSD
No RGB

Do you have some extra power to overclock? and isn’t the psu fan speed to noisy?

I was able to overclock my gpu by 200mhz and memory by 500 mhz with no issues. I limit my 9900k to about 135 watt. Haven't had any issues with power delivery. I did recently upgrade to a sf750 just for more headroom.

I don't hear my psu fan over my crazy blower style fan and cpu fans when it runs at max.

Was it too loud with the sf600? I might be using it around 80% with 500w draw at max

No it wasn't to be honest I never heard my PSU fan. Fans usually doesn't turn on during idle.

I just bought two RTX 2080 Ti’s and I am using the Corsair SF750 to externally power them, however, they will not power up. I have confirmed that the power supply is functional with a volt-meter. Has anyone on this thread had a similar issue?
