Power draw

[Mr_NumNutz]

Hi all.
i am planning a new build in the next couple of months and I am wondering if I can continue to use my hdplex 400 or if I need to sell and get something to cover power usage. I know there are supply calculators but I don’t believe them to be accurate for actual power draw.

potential parts list

3600x or 9600k (not interested in overclocking, just prefer the extra automatic boost)
itx board
5700xt or 2070 super
16gb 3200mhz
2x 120mm aio
2tb 2.5 5000rpm hdd
2x m.2 nvme

just depends on what deals are about at the time of purchase to if I go amd or intel, Radeon or nvidia.

oh and I have the dell 330w brick. If the hdplex will run it I don’t mind spending on their 400w AC/DC brick.

am I safe or do I need to get something like a 600-650w sfx unit?

I would use max 3600 and 5700 with that brick. Yeah you are better of with 550-650w sfx or flex psu.

 

[Mr_NumNutz]

fair enough.. thank you for your response.

No problem, if someone has first had experience they can also step in

From my experience, it's rare to max out both cpu and gpu usage at the same time.
In games, your gpu might be at max power, but your cpu usage might be only 25-75% of max power.
Desktop apps may max out the cpu, but gpu usage will probably be low.

Avoid running any stress tests.
Undervolt the cpu.
Undervolt the gpu or lower the power limit % in Afterburner.
Choose a basic motherboard with basic features and disable all unused features.

For reference, I'm currently running the following on my HDPlex 400 and a Dell 330w brick. I do have the HDPlex 400w AC/DC, but haven't used it yet.

Asus Z390-I
9600K
2x M.2's
2x 2.5" SSD's
32GB RAM
Single 140mm fan (CPU cooler)
LED lighting
7" LCD screen and associated controller
Zotac 2070 Super Mini

I've not had any issues despite heavy gaming usage on an Asus PG348Q ultrawide. I should add that with the exception of the 2070 Super, I've been running this hardware for almost a year. I was using a Zotac 1080 Mini until just recently.
