Unfortunately the motherboard was worst-case 166.2 W, not the
previous estimate/approximation at 80.
The 166.2 (motherboard W really doesn't include the CPU?)
So no it says it is is worst-case 277 W, and with +30% wiggle
room it is 361 W :(
back to passive 400W I guess ...

It does, see
https://www.techporn.ph/wp-content/uploads/ASUS-ROG-Strix-B450-F-Gaming-Benchmark-1.jpg
which is from your reference iv and explicitly shows an AMD R5 2600X
processor being used.

May I suggest you to compute it differently as follows?
device model/category max W note ref
-------------------------------------------------------------------------
CPU AMD middle end, 4 cores 130 2*65W [i]
fans 80 mm (3K RPM) 9 3*3W = 9W
120 mm (2K RPM) 12 2*6W = 12W [ii]
GPU geforce-gt-710 19 exact [iii]
mb Asus ROG Strix B450-F Gaming AM4 80 previous estimate
RAM ~DDR3 (1.5V) 10 actually, a DDR4
SSD 5
-------------------------------------------------------------------------
What did I change:
* CPU power doubled to account for short-time bursts.
* Motherboard back to 80W which should still be a safe estimate.
* RAM upped to 10W and SSD upped to 5W (depending on the actual components,
you might want to revert that but computing an SSD with 3W makes your
entire calculation dependent on that specific model and if you upgrade
that later you'd have to take it into account).
Sum = 130+9+12+19+80+10+5 = 265W.
With +30%: 265*1.3 = 344.5W
Hence it would be suggested to take at least a 350W PSU. Use a larger one if
you ever plan to extend the system.
HTH and YMMV

I'll subtract 65W from it then ...

Double it, that something one should do?
Default TDP
65W
AMD Configurable TDP (cTDP)
45-65W

I got these digits from
https://www.buildcomputers.net/power-consumption-of-pc-components.html
which is one of the first Google hits so I trust them for
now ...
As for upgrading that will be easy in this regard since I'll
read how many Watts on the box of whatever I get :)

In Intel world, yes :) In AMD world it seems to be slightly better, cf.: https://images.anandtech.com/graphs/graph16220/119126.png The TDP is given in the labels whereas the actual max power consumption observed is in the diagram. It seems that for AMD systems, the most extreme factor observed there is 143.22/105 = 1.364, so you might take that or round up to 1.5 rather than factor 2 for AMD systems. > Default TDP > 65W > AMD Configurable TDP (cTDP) > 45-65W > <https://www.amd.com/en/products/apu/amd-ryzen-3-3200g> > > > * RAM upped to 10W and SSD upped to 5W (depending on the > > actual components, you might want to revert that but > > computing an SSD with 3W makes your entire calculation > > dependent on that specific model and if you upgrade that > > later you'd have to take it into account). > > I got these digits from > https://www.buildcomputers.net/power-consumption-of-pc-components.html > which is one of the first Google hits so I trust them for > now ... The figures on that page for CPUs are misleading (they specify TDP range which is not much related to actual power draw anymore, see linked figure above). The remainder of the figures seems sensible. Some GPUs are also known to draw extreme peak loads (though usually that's only the "large" ones). SSD highly depends on the model. No need to argue for one general figure over the other. I think my SSD is specified 14W, but it is large and not the "newest" :) For RAM it seems that my figure is just a little too high and that your 3W are more correct in modern times. Nice to know :) > As for upgrading that will be easy in this regard since I'll > read how many Watts on the box of whatever I get :) > > device model/category max W note ref > ------------------------------------------------------------------------- > CPU AMD middle end, 4 cores 65 exact [i] > fans 80 mm (3K RPM) 9 3*3W = 9W [ii] > 120 mm (2K RPM) 12 2*6W = 12W [ii] > GPU geforce-gt-710 19 exact [iii] > mb Asus ROG Strix B450-F Gaming AM4 166.2 exact, incl CPU [iv] > RAM DDR3 (1.5V) 3 actually, a DDR4 [ii] > SSD 2.8 [ii] > ------------------------------------------------------------------------- > > total: > (ceiling (+ 65 (* 3 3) (* 2 6) 19 (- 166.2 65) 3 2.8)) ; 212 W > > with +30% wiggle room: > (ceiling (* 1.3 (+ 65 (* 3 3) (* 2 6) 19 (- 166.2 65) 3 2.8))) ; 276 W IMHO this is too low a figure for the system being planned. I am pretty sure it _will_ run on a 300W PSU, BUT probably not stable for a long time and under high loads.

OK, included ...

OK, it says the SSD and RAM are
Corsair Vengeance LPX · DDR4 · 2*8GB=16GB · 3600Mhz
250GB Kingston KC 2000 (SSD/NVMe/M.2)
if one can find exact digits, that's optimal, but what do you
search for to find out? I mean in general? The model name
and ... ?
Anyway, the computation now lands at 307 W.

I concur, my CPU has a TDP of 65W but getting all threads spinning in a loop jumps the power to more than 120W, and CPU quickly rising to max junction temperature (95C) for a minute or two until the the system resets :-( I installed thermald to manage temperatures, but it seems crap firmware/Linux design that lets system run at unreliable and life shortening temperatures without some user-side daemon running and throttle CPU speed to keep things from overheating. -- Tixy

Sounds like a bug rather than crap design (tho sometimes the line
between the two is hard to tell).

IIUC half-passive PSUs switch the fan off and on when needed, but there are also passive PSU that don't even have a fan, there are such that are 300W so after this computation that's the one I hope to get, to get an almost silent PC as you say :) -- underground experts united https://dataswamp.org/~incal

[2] Not sure this is going to help you, because mine is a low-power Intel build and you have a lot of AMD stuff, but, for the record, it is possible to get a lot done with very little power consumption, if you use a mid-range TDP CPU with an integrated GPU and stick to one SSD. Gaming PCs are a poor comparison for your use-cases because they focus on maximum GPU power and peak single-thread performance, whereas you need little GPU and compilation often benefits most from multi-threaded throughput. Any modern mainstream CPU should handle multimedia with ease using hardware acceleration; even smart phones can do this without breaking a sweat. My PSU is a mere 120 W, and I am a game developer, albeit targetting low poly games that will run on mobile. My 2017 build is still going strong. I am typing on it right now: - Streacom FC8WS Alpha fanless case - Streacom Nano120 fanless PSU with external AC/DC adapter - Asus H110I-Plus Mini-ITX motherboard - Intel i7-7700 65W CPU (Kaby Lake, HD 630 iGPU) - Corsair Value Select 2x8GB DDR4-2133 RAM - Samsung 850 Evo 250GB 2.5" SATA SSD - PCI-E WiFi card - Logitech MK270R wireless keyboard/mouse combo - Single monitor via HDMI - Headphones via analogue 3.5mm jack - External SSD via USB 3 Going fanless saves power. The aluminium case is expensive. Streacom cases are high-quality aluminium cases designed for HTPC applications. Heat pipe installation makes this the fiddliest build ever, equal with its FC8 Evo predecessor, but the cooling design works very well. The latest revision has more passive ventilation. This build is silent except for a slight buzz heard only during mprime torture testing with AVX enabled. I configured thermald to cap CPU temperature to 80C because paranoia. The only time I ever experienced stability problems was after an ill-advised RAM overclocking. Now I just Leave Well Enough Alone. This machine has compiled and tested massive amounts of Java (former business) and native code including many Linux kernels (git bisect). The HD 630 iGPU has met all my low poly needs, including development and testing in Godot, and modelling in Blender. The only time I ever experienced frame-rate drops testing a 3D game was when I forgot I had an eight-thread compilation job running on another workspace!

Not nearly as amazing as what will run on my three-year-old mid-range SDM660 Android phone: Firefox, YouTube, 3D games, Termux with Python 3.10, ssh/sftp, bash, nano, and more.

No, it is just a phone. 😀 My desktop just has a single BenQ LED monitor on HDMI, and I use a Logitech MK270R wireless keyboard/mouse combo. I think the monitor, which has its own external adaptor, uses about 30 W. I measured the AC power consumption of all my devices with a Belkin plug meter.
