New power supply makes no noise, but

in HW monitor the 12 volt rail says 11.77, while measuring the voltage on one of the connector wit ha DMM it said 12.11V, it is supposedly one rail for the 12 volt, is HWmonitor just not accurate?

The graphics card still makes a very quiet barely audible sound when rendering, but not a shaky buzz sound like the older psu did. I would think 800 Watt is plenty for a one vid card system. A total of 5 fans not including the one on the vidcard and psu.

The DMM is the accurate way of measuring voltage. And yes, 800 Watts is plenty for the system you have, with room for some add-ons, and some allowance for aging of the PSU.

Software voltage readings arent reliable, the DMM is the right way to measure the voltage so i would trust that and discount the HW Monitor readings.

Yar, since its a single rail I measured it with my DMM and it was about 12.11 volts, and 5.05v, or something like that.

HWMonitor just reads what the Motherboard voltage sensors tell it. If hey are miscalibrated, HWMonitor won't have the right number. DMM is the best way to go.
