Why is power delivery important?

[SGM]

I see it on a lot of motherboards and GPUs with varying degrees of marketing fluff about having 10 or 12 phase power delivery, premium alloy chokes, platinum capacitors, etc...

But why is that important? 

[TheKDub]

Better power efficiency, and probably better overclocking.

[Prikk]

10-12 Phase power = Maximum Overclocking.

 

And the rest are just Marketing bullshit, although they are more resilient to wear and tear, it won't be noticeable on normal use.

Cleaner power gives longer lifespan. The reason why having a higher phase count helps is because it allows the current to remain stable, and this helps a lot when you have components pulling a lot of power. The components also are more durable.

OCing and efficiency.

[Lays]

Longer lasting components, "cleaner" power, more voltage output whilst being stable, and it's more efficient.

 

Some people say it doesn't matter, and it doesn't really for the average consumer and 90% of overclockers for the most part.

 

It does start to matter when you start pushing large voltages through the CPU with custom cooling like custom loops / Ln2/ etc.

Thanks for the replies.
