after tab loaded power usage will back very low just 3sec only
very high wont stay long
but someone told Powerful CPU, but mobo quality is somewhat on the low-end side
I don't think it should be an issue, but it's possible that a capacitor suddenly can't take the TDP load requirement
you think this motherboard asus prime h510m-d is very bad
unable handle for CPU i7 11700K ???
what motherboard can handle for best handle i7 11700K
but not gaming because usage Office with multitask tab google chrome
i can buy new motherboard
how about PSU is Corsair VS550 for 550Watts
if not enough do i need change PSU + Motherboard ?"??
550W for your system without a GPU is enough. it's not about not enough wattage. It's not about whether high power long for a short while or not. It's the "sudden" spike on and off randomly that your PSU can't handle well and thinks that there is a problem thus it auto shut off. Faulty i would say. Anyway your PSU is crap. VS are are like kinda rubbish psu at the low tier.
Refer to this for your reference. I always use that as reference. No need until top tier...but if got budget why not..10 years warranty for PSU..or 5-7 years...probably tier 2-3 is better than 5/D/E.
