Will a 600W PSU suffice?

[linuxJo]

Hi

My cheap 700W PSU died this morning so its time to get a newer and better one.

My question is do I need 700W?

My PC consists of:

AMD FX 8350
HD 7770 Graphics Card
2 x Hyper X 8GB RAM
Gigabyte DS3P mobo
120GB SSD
3 x Internal 1TB Sata drives
2 x DVD R/W drives

I also use:

1 x Western Digital 5TB External USB 3 drive
2 X Verbatim 500GB USB 2.0 Drives.

I would be very grateful for any help.

Thanks in advance.
