r9 270x oc Limited PSU Options, Help!

[Gabriel_Marcera]

I recently bought a 2nd hand AMD R9 270X graphics card, slowly upgrading from a GT 520 (I know).

I realized it requires two 6 pin PCIE cables which my current PSU doesn't have, and is recommended to be used with atleast a 500w PSU. My current PSU is a 450W Thermaltake TT-450PL1NH-1.

My PC's specs are:
CPU: Intel Core i5-3470 @ 3.6GHz OC
GPU: Sapphire R9 270X 2GB Vapor-X OC
RAM: 8GB DDR3 HyperX KHX16C9X3/8
Motherboard: Gigabyte GA-H77-DS3H
HDD: 1TB Seagate Barracuda 7200RPM
Case: Thermaltake Commander MS-I

Since my options here aren't diverse and my budget is pretty limited, I found a Thermaltake Smart BX1 550W 80+ Br. but apparently it's out of stock. My next options and possibly only options are the Thermaltake LITEPOWER 550W that has no 80+ rating whatsoever, and the Thermaltake Smart RGB 600W 80+ which is a little bit too high for what I am able to afford.

Should I wait for the Thermaltake Smart BX1 550W 80+ Bronze, go for the LITEPOWER 550W, or save for the Smart RGB 600W 80+? Or can I get away with keeping my current PSU and using a PCIE 6 splitter?

I'm also not a 100% sure if all of these PSUs are compatible with my MOBO, so I might aswell ask for some insights.

at a guess, i'd wager that's all that's left especially at the low end
