Gonna build a Mini ITX Coffee Lake rig with an i7-7700k and a maybe a GTX 1060. Is a 450W psu enough if I don’t plan to overclock or should I go for a 600W?

Coffee Lake rig with an i7-7700k

hahahahahahahahahahahahahahahahahahaha. Funniest joke I have seen all week.

But in all seriousness what you just said can't be done. Coffee Lake and the 7700k are 2 completely different things. I think you were thinking of the 8700k.

To answer your question I do recommend getting the 600w psu.

Yeah I realized that I forgot which one is which. I meant Skylake. I think it was because I was considering Coffee Lake’s i5-8600k but decided I didn’t need the 6 cores.

Actually the 8600k is a better choice over the 7700k. Similar performance but much cheaper.

Similar single thread performance, it pulls ahead in multi core since 6 cores > 4c

Hyperthreading doesn’t make up for physical cores :)

I assume he was referring specifically to the 7700K vs the 8600k

I7-6700K= Skylake
I7-7700K= Kabylake
I7-8700k= Coffeelake

450W is plrenty. No need for more wattage on that system.

Also:

Skylake - 6th Gen Intel - i3/5/7 6xxx series.
Kaby Lake - 7th Gen Intel - i3/5/7 7xxx series.
Coffee Lake - 8th Gen Intel - i3/5/7 8xxx series.

Yeah I forgot Coffee Lake was the 8 series. I think it was because I was considering the i5-8600K but not anymore. Now I’m going with Skylake’s i7-7700K because I don’t think I really need 6 cores or hyper threading.

8600k is cheaper than the 7700k

Also the 7700k has hyperthreading

Nope, a 450 Watt PSU is more that enough. ;)

That's the real (total system) power consumption of an build with an i7-8700K (@5.2Ghz) and a GTX 1080Ti.

Build has as follow:

Coffee Lake System Specs

Intel Core i7-8700K
Asrock Z370 Taichi
32GB DDR4-3200 RAM (CL14)
Samsung SSD 850 Evo 4TB
Nvidia GeForce GTX 1080 Ti
Windows 10 Pro 64-bit

Power consumption of the above build

450w is more than enough but what is more important is what model the power supply is. For example, you don’t want any group regulated power supply for such modern build, as voltages will be out of spec or close to.

Depends on the psu.
