I'm stuck with PSUs while bringing my first rig to life. Begging for help.
I try to reimplement this build by nicahash, but with GTX 1070.
Now I have
- 1x Asus PRIME Z270-A. Up to 7 cards through risers + 1 by M.2 slot. Overall 8 cards max.
- 1x Intel Pentium G4560
7x Palit GeForce GTX 1070 GameRock [NE51070T15P2-1041G]. Samsung memory, good to overclock. One 8-pin connector on each card.
To power this I need about 2 kW PSU to feel safe (am I right?).
Obviously, I will never find such PSU, so I have to make multiPSU build.
So, my question is - how to distribute PSUs power between hardware?
E.g. I have 2 PSU - master and slave.
I figured out that it is mandatory to power motherboard and risers with a single PSU, so
-master powers up motherboard + risers + several cards with 8-pin.
-slave feeds all the other cards through 8-pin.
It is clear that one 8-pin is taking 150W max, how much should I provide for motherboard and risers?
