Choosing the right PSU for MSI X58 Pro-E

[phantomil]

Yesterday when I turned on the PC I saw a bright red light out of it and the PSU smelt burned (700W Thermaltake lp-700al2nh).I hope that it's the only thing that I will need to replace because for now i am still ok with my PC:
MB: MSI Pro-E X58
CPU: i7 - 920
Graphics card: AMD Sapphire R9 280
RAM: 2X3 GB DDR3
HD: 1TB SATA 2 72000RPM

please guide me to the right PSU for the Specification above, and if it can be used with new components (new motherboard and CPU if needed).

1| That's a really badly built PSU.

2| How much are you willing to spend on your PSU, where do you want to purchase from and where are you located?
3| Is the specs above all that is within your chassis or do you have other USB driven peripherals?
