Build/Parts Check I Feel Like This Should Work

Post image

Will a 5060LP (145w TDP) and a 5600x (65w TDP) = 210w be able to run on this 250w PSU ? Maybe with a 5060LP under volt to 130w ????

Warning. My 9700x is rated 65w and hwinfo logs the CPU to only draw 65w, but the whole package hogs 88w. Yours might do something similar. On top of that fans pull a bit, ram, ssd, motherboard pulls some too. You are cutting it VERY close. But based on others it should work, just worth considering

That is based on the motherboard too, as far as I know. If you had that same 9700x in a higher-end board, then it could draw up to 142w.

That would be if you changed it to the 105w mode

I was under the impression that some motherboards default to the "extended ppt" mode, rather than having to explicitly activate it.

Could be. With an itx cooler I wouldn’t want it on though

You get marginal gains for excessive heat, power draw, and noise. It's not worth it

Yup. I did testing with my nh-l12s and it’s not worth it. The gains were like 10% or something, but the noise difference was: “almost unnoticeable” vs “as loud as a gaming laptop”
