Just curious of the accuracy of this tool. Just put in
 
rtx-3080
amd x570 mobo
 ryzen 9 3850x (whatever the highest end was)
1 SSD and 1 HDD
overclocked cpu NO
and it tells me I need a 600-650W power supply. Minimum for a RTX-3080 is suppose to be 750W?
 
I guess no one pays attention to this thread anymore

3 weeks without a peep.
 After doing further research I'm assuming because the RTX-3080 XC3 black is voltage limited to 250W that's why it shows a 600W power supply would work. But then looking at the card it states a minimum of 750W. So something is amiss.
 

my system only draws 700watts when gaming but 850w PSU was very noisy, got myself a 1200 P2 and now it is silent, couldnt be happier :)
 

For reference, the power meter thingy says I only need 710W... I've seen JUST my CPU draw north of 190W according to HWInfo, and I've seen JUST my GPU draw north of 450W... and I have 14 RGB fans in my system along with 3 SSDs, 2 M.2 drives, and 2 physical HDDs... I think 710 is a bit on the light side.

Always buy big & high end is my saying when it comes to PSUs, if you get a Platinum certified PSU it is going to be 90+% efficient at half load almost all the time, so even if you're only pulling 600-800W, you're still being efficient, and if you ever get that "GOD TIER" 1200W monsterous system everyone dreams about but never builds, you've got the juice for it.
 
 

This will come in handy. Thanks.

So I only need 650w psu for my 3090? Then why is EVGA replacing my 850 GA with a 1000W G+? Strix 3090 was causing 850 GA to shut off.

Are the EVGA 1200 Watt power supplies Platinum certified ?

I’ve only got a 1000watt power supply 😢

I thought 1000watt was overkill , it was until this gen 😂

That is helpful
