Graphics Card vs PSU

[daemon1]

How to quickly find out which PSU will be able to take the load of graphics card. For instance I see that R9280x is having 1 x 8-pin, 1 x 6-pin as PCIe Power Connectors, does it mean that it will not be able to run from SEASONIC S12II 520 WATTS PSU as the description in this PSU says PCI-e-1 PCI-e 6 pin.

In the above case although the load is fine to take 280x but the 8 pin support is not present. Am I right or I am missing something?

I am just trying to understand the whole concept of this connectors.

Seasonic s12ii 520w has one 6-pin PCIe connector and one 6+2 pin PCIe connector.
So with that card requiring one 6 pin and an 8 pin PEG connectors there is no need for any adapter.
You would require an adapter with s12ii 520w if the card requires two 8-pin PEG power connectors.
Some cards depending upon design by the vendor can work with a 6 pin and a 8 pin configuration even if that card has two 8 pin PCIe power slots while some other won't.

@ OP - if your PSU has enough juice to power the graphic card you can always use converter connector to power up the graphic card even if your PSU don't has the necessary connectors. Most of the time such converter connectors are supplied with the card itself.
