im planning on upgrading my MOBO,CPU and GPU to an MSI gaming 5 with an intel 4690k paired with a gtx 780 and i currently have a xfx 550w and xfx 650w power bronze certified on 2 different pcs.
i thought i would be able to save money if i can use my 550w or 650w which i currently have or is that a bad idea?
is the power not enough ?
what do you guys think?

GTX 780 - System Wattage with GPU in FULL Stress = 340W/29 amps

Either of them can run a single GTX 780 system (1x 8-pin & 1x 6-pin PCIE). Use the 650W if you intend to overclock very heavily with over volting or just want peace of mind.

XFX 550W = 44 amps on 12v rail (1x 8-pin & 1x 6-pin PCIE).
XFX 650W = 53 amps on 12v rail (2x 8-pin & 2x 6-pin PCIE)
