Hello, I am currently building my bother a pc as a gift using my spare parts and i was wondering about P/S size.

There will be no overclocking on this system and the parts are:

4790k

2x R9 290x

8gb Ram

2x 850 Evo 250gb

2Tb Wd hdd

H100

6 Fans

 

I'm hoping i can get away with a 850w evga g2. Let me know if you think i should go with a 1000W to be safe.

The 850G2 is more than enough. You could go a bit smaller if you'd like. 

I wonder why you'd go with a Z97 board and K-sku cpu if you're not going to oc.

850 watts is more than enough for this system. :) I think even a 750 watt would suffice, and maybe even lower (but lower than 750 w would be cutting it close though). :)

I was using the 4790k and mobo in my pc while i was waiting for my evga sr2 come. That's why i have it sitting around.
