Will I need different/more power?

[mxk]

I'm changing my build plans of a 9600k to a 9700k and I've seen that the 9700k consumes a lot more power than the 8700k. Would I still be ok with a 650w power supply (overclocking a 1070Ti and the CPU), or should I up the wattage? I know which PSU's to buy I just want to refer back to here since I don't fully trust the PCPP wattage calculator.

650 Watts is enough for your setup and any single GPU setup configuration.

You'll be fine. I don't expect that system to draw much more than 350w at any given time.

Why?  About as accurate as any other PSU calculator out there.  Like most, it's going to tell you you need way more than you need.  650W is enough for your build.

the only problem I see with it is that it doesn't take oc into account while others do (even though I don't know how accurate their oc figures are)

I trust it's calculations for base clocks but 17030644 is right, I'm not entirely sure about OC's so thats why I asked.

50% power adder, tops.

I'll keep that in mind for the future, thanks.

is 50% enough? i've heard it isn't uncommon for components to double their power draw when OC'd

I guess we'll see when I OC the 9700k and my 1070Ti.

well it really depends on the components

 

some components don't OC too much, some don't require as much voltage.

 

But focus on having a good PSU, if you have a good PSU then it won't have any problems even if you push it

 

at worst it could shut down

 

not so good ones could even blow up, that's what protections are for

Yeah i've been using the PSU tier list (3.0). I'm getting my 9700k from an Intel employee, maybe the chips will be binned for employees? Hopefully.

it might make sense, but I don't know tbh
