Power Supply Help

[nageorgiou]

Hi community! This is my first time here, so I don't know what to say but hi. Anyway, I'm thinking of starting a PC business, and I need help calculating power supplies. I'm going to be making four variants of a single PC, and I need to know two different totals. The first total, is full load without overclock, just stock components at load. Next, I need to know the overclocked totals, I will specify the overclock speed with the components. Here they are.

A. GTX 750 Ti w/ Pentium G3258

B. GTX 750 Ti (lets say OCd to 1.4 from original 1.19) w/ Pentuim G3258 (OCd to 4.5 from 3.2)

C. GTX 960 w/ Pentuim G3258

D. GTX 960 (Let's say OCd to 1.5 from 1.22) w/ Pentium G3258 (OCd to 4.5 from 3.2)

E. GTX 960 w/ i5-4690k

F. GTX 960 (OCd to 1.5 from 1.22) w/ i5-4690k (OCd to 4.2 from 3.5)

G. GTX 980 w/ i5-4690k

H. GTX 980 (Let's say OCd to 1.45 from 1.23) w/ i5-4690k (OCd to 4.2 from 3.5)

Thank you for the help!

EDIT: I also need to know the efficiency of the Power Supplies (e.g. 80+, bronze, silver, gold, etc.) And Im going to be using all EVGA PSUs

I believe that you would want a good PSU for all of those builds.  Stick with ANY Seasonic or well reviewed PSUs from others such as Corsair, Rosewill, EVGA, Antec, and friends.  Just not Diablotek.

 

1. 400-450W
2. 400-450W
3. 400-450W
4. 450-500W
5. 450-500W
6. 500-550W
7. 600W
8. 600+W

A better place to look would be by filters.

@nageorgiou This minus 200w on each one. Maxwell gpu's take almost no power, same with intel cpu's. Really you just want a solid 450w minimum for even the last option. Even with the last most power hungry option you will probably only pull about 250-300w from the wall.
