I checked the guides in this sub-forum, but the links are outdated. So now what website can help me calculate my PSU requirement based on my rigs?
 
Solution
PSU calculators are deadly accurate if you can enter all of the info?
Some are unknowable.
What, for example do you enter for capacitor ageing?
What will be your future graphics upgrade?

My go to source is this table:
http://www.realhardtechx.com/index_archivos/Page362.htm

Then,
I will consider overprovisioning a PSU a bit. Say by 20%.
It will allow for a stronger future graphics card upgrade.
It will run cooler, quieter, and more efficiently in the middle third of it's range.
A PSU will only use the wattage demanded of it, regardless of it's max capability.
You will often find that a step up in psu power comes at a minimal cost.

My other key is to buy only a quality psu.
Look for a unit with a 7 to 10 year warranty.
I personally don't use those online PSU calculators anymore too.
If you need an actual wattage figure, try to look up on the actual power draw from testing websites or youtube channels that show the wattage draw at idle and under load for each of your component(s) to give you a rough idea.

Maybe tell what is in your pc and also do you want upgrade room?
I have
intel core-i7 11700F,
gigabyte B560 aorus pro ax,
corsair vengeance lpx 8G*2, ddr4, 3200,
western digital hdd red pro 2T,
samsung 970 evo 1T,
MSI GTX 1070Ti titanium,
asus DRW-24D5MT optic drive.

I think I will upgrade my graphic card in the future. Appreciate it if you could suggest some PSU!

Thanks! Could you recommend any testing websites?

Some options from different brands,
chose 750watt as a good wattage looking at some of the more power hungry gpu's these days, but depending on what yyou might upgrade to can 650 or 850watt be fine too.

A "Tier" list we have here, wouldn't go lower than Tier B, but these above are all in Tier A.
