Hello,
I have the following PC:

CPU: Intel Core i5-4670
Motherboard: ASROCK H87 PRO4
GPU: Gigabyte GeForce GTX 770 OC 2GB GDDR5
Heatsink: Cooler Master Hyper 212 EVO
RAM: G.Skill RipjawsX 2x4GB DDR3 1600Mhz
HDD: Seagate 3.5" 1TB SATA3
PSU: FSP 550W Raider 80+ Silver

If I add another SATA HDD, a Firewire PCI card and a DVDRW unit, will the PSU give enough power?

Thank you!

I will not do SLI or overclocking, just the components I have listed and the ones I want to add.
In this case, will it be enough?
