Hi peeps, lets start with my build:
i5 6600k 4.4 OC
GTX 1060 6gb Gaming X MSI
4x4gb DDR4 3000 OC'd Crucial Ballistics
2 SSDs and 1 HDD
MB: z270 Gigabyte
A fan Cotroller with 5 120Fans
Max power draw under stress tests is something around 450Watts

I wanted to ask if a 850Watt PSU is ok, cuz a found a good one from Microcenter for 90$, its a Thermaltake Toughpower Grand 850 Watt 80 Plus Gold,i know that a 550 or 650W is enough for my pc but thats a awesome deal for a Tier 2 PSU.
It will be efficient for my build?

91W CPU, 120W GPU....
Even with overclocking, I'd be very surprised if you were drawing anywhere close to 450W under full load.

Regardless, an 850W unit won't cause any issues..... You'll be operating outside of peak efficiency more often than not (80+ units peak efficiency is ~50% of rated max)

Considering you can have some of the best PSUs out there (in the 550W range) for nearer $60-$70, I don't see any real reason to opt for that unit, even at $90.
