2x Corsair HX1200W PSU’s ( Not sure if I have enough pins though as I need 1x 6 Pin and 1x 8 Pin for each GPU
AS ROCK BTC PRO H110
G3930 CPU
4GB Kingston HyperX RAM
32 GB USB for HDD
This should use 1823 Watts, Is it better to use 2 PSU’s I’m also from the UK so I am pretty sure we use 30A breakers for socket outlets, could I get a 2400w Server PSU that’s rated and how would I go about fitting all the pins in as I need
Unless you are underclocking the power, your usage is wrong.
A 1080ti stock uses 235w-250w, 8 x 250 = 2000w, this does not factor in risers, mobo/cpu, HD
Keep in mind that @CitricAcid is referring to usable power at the device. I feel folks often overlook the fact that the draw at the wall (which feeds into breaker loading) is just as important. Every PSU has an efficiency curve which varies with loading. You must divide your device loading by the efficiency to obtain a good estimate of draw at the wall.
Platinum PSUs are more robust units and will be more efficient, but 92-93% efficient is tough to beat. On small loads it doesn’t usually make a difference, but with thousands of watts in play, it sometimes can.
I am not sure if for 8 gpu rig this will count. But dont the line from the wall need to have a backup safety key of 20 amps ? Most wall plug only have 10 amps. My english isnt the best. Does anyone know what I mean?
Full load ratings are , to the best of my knowledge, 0.8 * breaker rating. That’s the standard in the US, anyway. So for a 20A breaker, it is generally recommended that sustained loads be maintained <= 16A (I [Amps]* V[volts] = Power [Watts]).
Sustained loads need to be under the threshold by 20%, so he is saying:
(30*0.8)*230= 5520W, that’s the safe amount, and the maximum (but still unsafe) is 6900W.
Did I say I was going to put 7000W on 1 socket no…, I was going to use 2 3000W PSU’s on 2 plugs on the same socket (at some point not now) It won’t even use 6000W probabaly just over 5000W which is safe…
