Ok, so here's the parts I got.

Intel Core i5-4430 quad-core processor
MSI B85M-G43 micro ATX motherboard
Kingston HyperX Fury HX316C10F/8 8GB DDR3 1600 RAM
XFX R9-280X-TDFD Radeon R9 280X 3GB video card
Samsung 840 EVO 250GB SSD
Seagate Barracuda 2TB HDD
LG GH24NSB0B DVD burner
Seasonic G Series SSR-550RM 550 watt modular power supply
Corsair 230T ATX mid-tower case

So, issues...
XFX R9-280X-TDFD Radeon R9 280X 3GB video card
Seasonic G Series SSR-550RM 550 watt modular power supply
Incompatible..?

Everything was going fine when I was building my PC until the wiring for my video card.
I looked at the quick installation guide and I saw this:
"XFX does not support the use of two 6-Pin to one 8-Pin power cable converter for these graphics cards. They are only designed to work with high performance power supplies using 8-Pin PCI Express power cable."

Now, first of all, this card came with a converter for two 6-pins to 1 8-pin. So I'm a bit confused by that.

Secondly, my PSU did not come with an 8-pin power cable.

I read this review on newegg: "you need two PCI power connectors for the 8 pin power connector on the card as well as 2 molex connectors for the 6 pin on the card."

So, I'm wondering if I'm not understanding something here. Or if I need to buy something additional. Or am I SOL, and need to return/exchange my PSU? If I am SOL, what PSU should I get?
 
Solution
The warning is so that you do not overwhelm a lower amperage 12V rail. Since the Seasonic G Series SSR-550RM, has only a single 12v rail, you do not run that risk of overwhelming it. You do have 2 6+2 pin (which is the same as an 8 pin) connectors so you should be golden
Summary, no incompatibilities there
