It might be just right. I've read 30% headroom is a good idea if you're starting
afresh. The largest I own is a 700W, used only for bench testing & burn-ins. The
largest I have installed, of which I own only one, is a 550W. I also have
installed multiple 500s, 450s, 380s, 350s, 430s, 400s. Most that are smaller are
OEM, mostly Dell, one HP, and old. I've needed to recap most of the older ones.
About half my PCs only have IGP, no discrete graphics. Most of this is to say it's
/easy/ to think you need more than necessary when the sale ads feature mostly
those above 500W, many of which have triple digit price tags. Using the online
calculators is smart. :)
None of my PCs have dual cards except for this one, which is using a 500W:

The NVidia cards are old and lower tier, and their heat sinks aren't very big, so
each fits in one slot, and doesn't require gobs of power.
You may notice the above inxi output is not from Debian. Neither Buster nor
Bullseye are able to find outputs on Device-2. On TW, all four are found and used
automagically.
