Kingston HyperX 3K SSD 120GB
Zotac GeForce GTX 780Ti
Intel Core i7 4670k
MSI Z87-G43
Crucial BallistiX Sport 1600Mhz 8GB

And maybe i'll put in a 1TB hard drive in the future and 8GB more RAM.

But how big of a PSU would you recommend?

For a system using a single GeForce GTX 780 Ti graphics card NVIDIA specifies a minimum of a 600 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 42 Amps or greater and that has at least one 6-pin and one 8-pin PCI Express supplementary power connectors. There are some non-reference design cards that require two 8-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) is the most critical factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

Pretty much anything made by Seasonic.

All of XFX's PSU models use Seasonic as the OEM.

Antec. Corsair TX, HX, AX and AXi series. Enermax.

The Rosewill models that have a 5 or 7 year warranty are also good.
