I just bought a Radeon R9280X. New Egg and several other sites said the minimum PSU was 750W. So I bought one of those to replace my 550W supply. Now I read this article:

What gives? Why the huge difference in minimum PSU requirements?

Minimum PSU of 750W is not required for this card. Depending upon the rest of the system you have, 550-600W would be sufficient. Better to ask first before buying

750w is the reference spec given by AMD to cover people with cheap power supplys.
Any decent 500w power supply will be enough for a single 280x.

600+W per RealHardTech. eg Seasonic 620, XFX 650 or Antec HCG 620M

Different GPUs can use different amounts of maximum power.
