That memory is too slow for anything new, unless you want to seriously hamstring the performance of your new system right out of the box.
SSD is probably fine if it's not too old or too small. If you're happy with it, then it's likely ok for now at least.
The EVGA 600w bronze is likely a low quality power supply by comparison to anything we'd call high quality or reliable. It's likely either a B series, BR series or something similar. They don't make a "good" 600w bronze model, so we know that regardless of WHICH model it actually is, it's probably a good idea to think about looking for a higher end model even if you weren't going to be upgrading. If you upgrade, it's the FIRST thing you should be looking at.
I realize it's difficult to get quality power supplies where you are, and expensive, but those facts don't change the fact that it's something you need to consider. Your system doesn't care that you live in a region where it's hard to find a quality unit. It only knows that poor quality units don't perform or last in similar fashion to higher quality units and that lower quality units tend to bombard your caps with high levels of ripple and noise, which shortens the life of the capacitors on your motherboard and graphics card. Not to mention a cheap unit, even a mediocre unit that we wouldn't expressly call "cheap", might lack some protections or have protections that are not implemented properly and might make your hardware vulnerable to damage.
Below you will find MY standard list of recommended power supplies and beyond that this thread is intended as a landing place for questions or discussions regarding specific units, platforms or related PSU tech, all of which are all welcome to be discussed here. If it's related to power supplies...

You did not mention what CPU and motherboard you have right now, and that would be at least moderately helpful in determining where you are coming from in order to figure out where you need to go.
