October 2, 20205 yr Through a series of events, i have access to a Corsair RM 1000x Gold PSU that i could pull from another build (for which it is overkill) Wondering if i should swap my 650W Seasonic Titanium Everything works fine as is, and i don't have any plans to add another GPU anytime soon. Maybe one more HDD at some point. Below is configuration, and using PSU calculator i come up at 590W recommended. which is getting close. However, i really value the efficiency of the Titanium Seasonic NO overclocking etc. Can i easily measure power draw? What happens if I exceed 650W? will system become unstable or simply retard performance when pushed?

October 3, 20205 yr A UPS is recommned for unraid so that in the event of an outage you get a clean shut down. My APS brand UPS was ~ £60, $75. You only need a few minutes of run time for an automatic clean shut down. Most will give you a power draw. Just make sure it supports the APC plug in (via USB) Alternatively you can pick up a power meter than plugs into the wall fairly cheap £10, $12 which can be usefull to see what uses the most power. Off topic, but my old fridge freezer is a power hog using nearly 3x the power combined for a later fridge and freezer with more space. It's on the replacement list now! APC plugin in Unraid Note, this is at the wall power so at 90% efficiency means real consumption of 90W As for your power supply, The calculator recommends 590W which has a fair overhead to keep you in the efficiency sweetspot. Realistically your PC will be peaking around 350-400W. I'm only at ~400W with a 3700X and Vega 64 so I'd leave it as is for now. If you add another GPU then I'd look at an upgrade.

The PS has power monitoring circuits which do that function. I have not overloaded a PS for years but in the olden days when you exceed current draw (which is what is monitored), the output voltage would go to zero-- totally eliminating the overload. (These circuits are designed to protect the components in PS, not the load connected to it!) That is the reason why a 750W PS costs more than a 600W one.
