Do I NEED a "Tier 1" PSU?

[Dagnis]

So for my future build I'll be going with an i7-8700k, and a 1080ti. I'll be overclocking both to an extent.  I was thinking 800-850 watt would be more then enough, giving me headroom so nothing silly happens. 

 

Anyways. I'm debating between the tier 3 BeQuiet Straight Power 10 (semi mod) at 800w, and the tier 1 BeQuiet Dark Power Pro 11, 850W (full mod). My question is, will I find much benefit in spending the extra $50 for the Power Pro 11?

Cheaper power bill, but cleaner cables with fully modularity. But also, full custom cable sets cost much more than extension

Never skimp on your power supply.  The extra $50 is well worth it.

Tier 3 is what I would recommend for low end gaming PCs. Since you are going to be high end with a 1080ti and 8700k when they launch, you really should get the Tier 1 to get the very best performance and stability.

When you spend lots of money on an i7 8700K and a 1080Ti a Tier 1 PSU would be appropriate in my opinion. And use a PSU power calculater because 800W is more then you probably need anyways.

You're better going for a lower wattage Power Pro 11 than a higher wattage Straight Pro 10 if it's saving you money.  Good quality PSU is important but wattage has less significance these days.

It's a piece of your build that gets used ever time you use your computer no matter what you are doing.  It affect every other piece of your build.  Tier 1 or 2!

Thank you everyone.

Looking at the sticky thread it would seem 750W would be fine (since 650w is recommended for top tier, with OC)

800w is more than he needs, a 500w PSU would be sufficient, but efficiency of a PSU is actually peak when its around 50% usage so this would likely fit right in with that build at max draw which will likely be between 450-500w

So where did you get this crystal ball that tells you the 8700k will be good?

I'm under the opinion that you don't need a top tier PSU. It's something to help you sleep better at night, but all it'll get you is probably a lower electric bill (by meager percents if anything) and maybe slightly more useful life of those parts (that already have a useful life of "lol that thing is ancient" by the time it dies).

If you're getting a nice hexacore and a 1080 Ti then a  T2 is fine and really you wouldn't be frowned upon for using a T3 unit from me.

Yes and no.

 

There is a point where you have the optimal unit. 
The extra money for the Dark Power Pro isn't a bad idea.

The Extra money for the 850W version is.

550W is more than sufficient for his build.

And SLi/CF sucks. It rarely works these days anyway. Only on some Tripple A Titles it may be a viable idea. For everything else (like Nier Automata) It's just a waste.
