My PSU: https://www.coolermaster.com/catalog/legacy-products/power/v650s/

Specs as follow:
CPU : i5 11400
Mobo: Gigabyte B560M Aorus Pro AX
Graphic card: Gigabyte GTX970

I tend to use the CPU with no power limit. Will the Cooler Master V650 be able to handle the load? Or I should switch to a higher power PSU?
From what I read, the graphic card seems to draw ~290W at full load. The CPU seems to draw ~200W at full load with no power limit.
Thanks in advance!
Update: from the efficiency curve provided by Cooler Master. It seems that my PSU is able to keep 90% efficency at full load @230V. Which mean I'd have approximately 85watts to spare?

11400 draws about 120w and a GTX 970 about 170w. GTX 970 can't max out a i5-11400 do the CPU draws less. Power consumption of the complete system is 300 - 350w. 650w is plenty and a Cooler Master V-series is a high quality PSU.
Thanks, do I need a good air cooler for no power limit CPU? Or the stock works just fine?
 
Definitely a better cooler. I use a be quiet Pure Rock 2 on my i5-11600 with no power limit. Dead silent and max 68 degrees C.
You stated that GTX970 can't max out I5 11400 anyway, then does it matter to remove the power limit of the CPU? I do light work like Microsoft Office, Web surfing, and casually play some CSGO @144hz only.
