I have a 160GB WD HDD just lying around and Radeon HD 7770 1GB DDR5. Can I install it in my system without overloading any components?

My System(A bit obsolete):
Corsair VS550,
Gigabyte 78LMT - S2,
FX 6300 3.5GHz,
4GB + 4GB DDR3,
320GB Hitachi HDD + 160GB Seagate HDD,
one cooling fan.

Thanks in advance
