System Power Requirements

[cja711]

What size power supply would I need to be able to run this system (below) comfortably

System:
CPU = Intel Core i5-6500
Motherboard = Gigabyte GA-B150M-D3H
Ram = Crucial 8GB DDR4-2133 Memory
Graphics Card = EVGA GeForce GTX980 4GB Superclocked ACX 2.0
Hard Drive =500gb Seagate Barracuda

I was thinking a Corsair RM 550W? But I'm open to suggestions

Thank you all

well you could figure the max amps

chip 80w[??] say 10 amps 980 300w 25 amps [8 pin 150w 6 pin 75w slot 75w = 300 w full power draw ] rest of system 10amps so right there at everything pulling full load that's 45 amps at the 12v+

w/v[12] = amps allways figure for max full load power draw even if it just spikes to it


so with that you can do your own figuring /math as you see fit

A good quality 550 watt PSU with adequate +12 V amperage would be plenty to power a system with this video card.

550w psu should be 45 amps at the 12v+ but ??

now heres the trick in this and the card you see power consumption if ''at the wall'' not from the psu to the card

so you got to figure why the card needs a 8 pin and a 6 pin plus slot power ??? why cause they know the card its self can draw up to 300w as I showed above ??

Don't get the RM , get a RMX 550W or an EVGA G2.

Unless you are getting one hell of a sweet deal on the RM 550 then I would suggest a better unit by seasonic or EVGA (g2/b2 series).
Don't want to cheap out on a PSU and fry that $500 GPU.

Also, for that high level of build, I would advise to get a better motherboard. Buy for what features you think you will need 2-3 years from now.

Buying a GTX 980 now? Why? It was a poor value card originally, and now is much worse value with the 1070 and 1080.

Good Point!

I don't know how much the GTX 1070/1080's are and the 980 was just an option I knew about, I'm more focused on the cpu motherboard and ram etc, the graphics card will come later... With regards to the 1070/1080 how much are they roughly going to be and would I need more than a 550W power supply?

 

[mlga91]

The 1080 and the 1070 will be around $600 and $370 respectively, and quality 550W PSU will be more than enough for your planed build plus any of those cards.

'' would I need more than a 550W power supply''

with just what yopu got above you see a 550w is bare min and -0- overhead you need a 600w or higher you could ''get by'' with a 550w but you may find you can over push its limit on the amps at 45a so if tyour system tried to pull over that 45a you have a issue [crash /bsod / ?? ] go with a unit that's 5/10 amps overhead 650w should have 55amps at the 12v +
