how many watts?

[jeremymwilson]

Hi everyone,

 

I am building a system with: i7 6770k, MSI Z170A SLI Plus, Gigabyte gtx 1070 Windforce OC, 16gb 2400 ddr4, 850 Evo 500GB.

 

I was planning to buy an EVGA Supernova G2 550 but I also might be adding a 2nd 1070 next year and want to know which PSU to get for SLI. I might do a little CPU and GPU overclock but it's not essential.

 

Is a 650 watt PSU enough or should I go for 750?

 

cheers

A 650 watt is more than enough, 750 would be overkill.

650W is definitely enough. That PC would run on a 400-500W PSU.

650W is fine but I'm actually going to recommend that you grab a 750W as Pascal cards use more power than Maxwell cards and 1070s overclock to unbelievable clocks and voltage. It wouldn't hurt to grab a 750G2.

Unless you're going to be adding more things in the future. 650 is fine for where you are right now.

thanks for all the good advice. To be honest I change my mind on a daily basis on what my build will be, so planning for a year from now is impossible. At the moment I have just the case and plan to order everything else in November.

 

I'd say there's a 70% chance of either adding a 2nd 1070 or swapping for a 1080Ti next year...

 

So that, along with probable modest cpu and cpu overclocks, pushes me towards the supernova 750.

The Outervision calculator is garbage. Same goes for the Cooler Master one. Don't use them.
