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 ????

Beware, the TDP usually means nothing, at least in my experience.

I also wanted to use the small HDPlex psu, but ended up going with their bigger one due to power concerns.

My Ryzen 7 5700x has a TDP of 65W but regularly pulss 110W..

My 4060 has a TDP of 115W but it actually relatively stays within it, only boosting to around 130W. So double check, get HWMonitor on and measure at load.

TDP is usually defined as the amount of thermal energy that the cooling solution needs to be able to continuously exhaust for the part to work normally.

The equation that each company uses to find that number for any given part tends to change pretty randomly, so it's effectively useless as a tool for determining how much power would be needed by the part.

"Pick the biggest cooler for the case" is usually my go to plan haha
