Hi. I've been asking around as I'm looking into a adding a 2TB 7200 Internal HD and two USB 2TB External HDs or perhaps one USB 3TB External HD for security backup. I currently have a Seagate 7200 1TB SATA II drive and it's being filled real quick with games and music.
This is my CPU...

When asking around, someone suggested that I get a 400W PSU as my currant 300W would in insufficient for the equipment I'm going to purchase.

What I'm wondering...is this really needed or worth it? I plan on getting rid of this PC and giving it to my mom for simple internet browsing and music playing in a couple of months. I'm gonna get a great gaming PC. Also, I have a 2 year warranty on this and I don't want to void it.
Anyway, this is the one I'm looking at...

Would this work OK with my PC? Could I risk damaging something? Would it be easier on my system to just add a second Internal 1TB instead of a additional 2TB?
Any help would be grateful.
