how much does the PSU really affect overclocking

I see everywhere that lower ripple and better voltage regulation help with overclocking

but I don't know to what extend it really makes a difference (I'm talking about ambient OCeing)

Cpu overclocking depends on the quality of the motherboard vrm, Gpu is the same, but depends more on silicon lottery. But you still want to get a decient power supply.

so your answer was basically no

cpu wise nothing. now gpu. then yes. you want a 80 plus rail

80 plus rail? what are you talking about?

and why would it affect the gpu and not the cpu? I don't understand

basic googling would help. but a good gpu uses more power draw then a cpu does.

but there's no such thing as 80 plus rail, hence I asked what you mean by that

i meant in general on a gpu. . on rail i meant the amount going to each of the power hungry parts. 80 plus was the ref of not wasted energy .

I am a bit confused

good GPU doesn't mean it will draw more power

and that doesn't apply for skylake-x i9s.

seriously?

can you back it up with something?

This is more or less false. Ripple can have an effect on extreme overclocking.

If you're trying to break overclocking records, it's best to have a PSU with less ripple. For a standard overclock, ripple should be mostly within ATX specification. (120mV on 12v and 50mV on 5v and 3.3v)
