Psu enough for new system?

[Zenze]

So I'm doing some major upgrades to my rig and wondering if my current PSU is enough to handle it all safely. I admit I don't have much knowledge about PSUs and how much wattage/amperage on each rail is enough.

Here is my current power supply: Seasonic 650W

And this is what I will need it to power:
Asus P55 mobo
Intel i5-750
Radeon 5870
A couple DVD drives
A couple hard drives


So do you think that my 650W PSU will run all this safely? Thanks for the help.

Seasonics have a reputation of legendary quality & reliability.
So your system is easy peasy for the PSU. It'll run just fine, don't worry.

I had heard that they had a great reputation which is why I chose them a few years back.

Thats what I thought but I just wanted to make sure/get a second opinion.
