How much power will my PC need?

ChapyYxx · Feb 26, 2014

I'm working on my first PC build and need to find out how much power I'll need. My build is as follows:

i5 4670k
Msi z87 gd65 board
Asus GeForce gtx 760
8-16 gb RAM(still deciding. Taking suggestions.)
Apevia x-Hermes case
Pretty generic DVD drive. So how much power should I get? Thanks for reading.

A 600 watt should be fine. You could go with less if you need to save money. As I always say, the more the better. But, I HIGHLY recommend that you get a modular power supply. If you plan on going with SLI eventually, I recommend getting something a little higher. I would watch this video if I were you. http://www.youtube.com/watch?v=LiWThqgFfI4

Try this PSU calculator
If you are not on a budget I would go with a 750 or 800 watt not that you need that but in case you ever sli or something like that

You really don't need that much power. Ignore those who say you need anything higher than 650 watts. Even with SLI, you would be fine with that. Just get a 600-650 watt modular power supply.

You don't want to cut it to fine. PSU work best at 50-60% load. 1 GTX 780 will run fine on 600-650w. 2 780's you will need more, 800w

TheMagicalWallaby :

My crossfired r9 270s will run on 650w psu barely. My question is why would you want to get a 600 watt psu that leaves no room for upgrades? In my opinion (unless on a tight budget) if you are going to go 650 you may as well go 700 just to be safe 500 watts is fine if you are 100 percent sure you will never need more power . Just my opinion
