Could the Corsair RM 550 Power this

[SuperChil]

I need some expert advise, I recently used a PSU calculator (which in most cases seems to be accurate ) which stated that a corsair RM 550 could power up this system without any problems

System:
CPU: Core i5 4670k (might be overclocking)
MOBO: Msi Z87M Gaming
SSD: Samsung 250 Gb SSD
HDD: Western Digital Black 1 TB
COOLING: Corsair h100i
GPU: Sapphire 270x toxic (in crossfire)
RAM: Kingston savage 8Gb ram

[strike]It can power it, but I would buy something else.[/strike] The RM doesn't have the best capacitors.
Just noticed you mentioned cfx, nope.

If you got a single 290 instead of 2 270Xs it would work fine, and perform better.
