It is crazy how much energy lessor tiers of PSUs waste. I have been feeling a bit like a zealot, preaching "GOLD! Titanium! Platinum, my brothers!" for the last few years. Thanks for the confirmation that even Silver PSUs are wasteful.
One thing to note on power supplies greater than 5 years old, is that they start to lose efficiency. [H] did periodic reviews of their supplies that were 10 years old, and were often showing a 5% (or more) efficiency loss. I would direct link to one of the articles, but with the site being gone and all..By chance I checked my PCs idle power earlier, it was ~80w.
Seems like a large part of that could be down to the 11yr old 80 white Corsair PSU I have! But that said, my PC almost never idles (although a gold rated Corsair RM550x is in the pipeline for better loaded efficiency).
Oh Tony (et all), you might find this interesting, my PSU posts at OcUK (a thread I subscribed to donkey years ago! lol), efficiencies vs cost pay back.
Here is the matching forum thread - looks like the supply did well, but no great summary of the results:
The website's gone!? Damn! Didn't know that , admittedly I didn't go there often, but I did like it!One thing to note on power supplies greater than 5 years old, is that they start to lose efficiency.

They did 3 or 4 10 year tests that I remember.The website's gone!? Damn! Didn't know that , admittedly I didn't go there often, but I did like it!
Hadn't even crossed my mind that they would go 'off' over time, that was really cool that H OCP did some 10yr testing!
I found page 5 btw! (DC output quality), graphs aren't clickable though. Well the voltage ripple had hardly changed, I guess we won't know how the rest of test went .
See, you understand! It’s really the efficient thing to do until Ryzen 4 and the 3000 series vid cards come out.So for the sake of efficiency I should get 16C CPU & an RTX 2080 then?
Didn’t even think of that. Should be like blue and orange or something.Btw, does anyone else think the choice of colour in that graph is utterly stupid for the 2 different voltages? Blue, and err blue! Wth!? lol
I am running CPU projects often and GPU projects rarely. Plus, I ended up with computers which are solely dedicated to Distributed Computing. I therefore built computers of two types:So for the sake of efficiency I should get 16C CPU & an RTX 2080 then?
I forgot that you had posted that. That is some very solid efficiency, and it’s just a single host to manage.FWIW, here are my dual-EPYC 7452 (dual 32c/64t Zen 2) numbers with 100 % Rosetta@home load from early April again:
average core clock 2.6 GHz — 340 W power draw at the wall — 82,800 PPD host credits, averaged from >130 results
So that's ≈250 PPD/thread/GHz, and ≈240 PPD/W.
Your FreeDC link as well as your hosts list at R@h show the host ID 1761696. Boincstats has got a record of the last 60 days of production: It is showing about 12 kPPD during the last few days.
