IS 750 W GOLD ENOUGH FOR 1080 WITH 8700K

Hey, 

I've been really confused what kind of power supple to use for my PC. Parts List:

  1. Gigabyte GTX i1080
  2. intek i7-8700K
  3. 2x 8GB 
  4. 1TB HDD 
  5. 240GB SSD 
  6. Liquid Cooler 
  7. 2 Fans

Nothing fancy but Canada Computer Employees who I talk are telling me to get a 800W-900W Gold PSU even though the Cooler Master Calculator says that my PC parts need 470W. 

Currently I have EVGA 750W 80+Gold Modular power supply. Is it worth it to get a 800W-900W or will this work out for me?:)

urgh, he doesn't know what he's talking about.

PSU are voltage converters, those are rated for output power, not input.

 

And with 800-900W, you have absolutely no way in hell to cool that with conventional measures. You need real hardcore stuff for that, with a single GPU and CPU. 
Ergo: That's enough for a Multi CPU/GPU System.

Even though that thing overestimates by a mile, the other guy just seems like he either didn't know stuff or tried to convince you that you should spend more money than was necessary....

 

As said, a good 550W is more than you'll ever need..

Agree with @Stefan Payne

Those guys are trying to make an extra sale.

 

Even 750W should suffice for SLI GTX 1080's.

900W is just overkill.
