If (= provided that) you can trust the manufacturer for that statement "300W PS". I tend to be wary of such statements. The maximum current provided for each voltage output would be more significant than the wholesale advertisement of "300W PS". Your calculation might be well within the limits in general but what if the load for e.g. 3.3V goes up to 12A but the PS is only able to deliver 10A? It might be well able to deliver 20A for 5V and 8A for 12V but your load does not need 5V or so much at 12V but more on 3.3V or even 1.8V. So be careful and have a look at each needed supply voltage and its power rating. > > GPU geforce-gt-710 19 [on which voltages?] > CPU AMD mid end (4 cores) 125 [on which voltages?] > fans 80 mm (3K RPM) 9 (3*3W = 9W) [12V] > 120 mm (2K RPM) 12 (2*6W = 12W) [12V] > motherboard high end 80 [that is on several diiferent voltages] > RAM ~DDR3 (1.5V) 3 (actually it is a DDR4) [on which voltages?] > SSD 2.8 [5V and maybe 12V] > > Total: > > (+ 19 125 (* 3 3) (* 2 6) 80 3 2.8) ; 250 W > > Total, with the GPU removed: > > (+ 125 (* 3 3) (* 2 6) 80 3 2.8) ; 231 W > > Total, with 25% wiggle room: > > (* 1.25 (+ 19 125 (* 3 3) (* 2 6) 80 3 2.8)) ; 314 W > > Total, w/o the GPU, w/ wiggle room: > > (* 1.25 (+ 125 (* 3 3) (* 2 6) 80 3 2.8)) ; 290 W > > https://www.buildcomputers.net/power-consumption-of-pc-components.html > https://www.techpowerup.com/gpu-specs/geforce-gt-710.c1990 all by rule of thumb - and it's a very thick thumb with carpal tunnel syndrome I reckon. -- Eike Lantzsch ZP6CGE
