Those metrics do not make a power supply good. Not remotely...and newegg.com reviews are 90% garbage outside of DOA's as, for the most part, the people just dont have a clue what makes things 'good'... and some of those comments are just, well... funny. Proper PSU REVIEWS are what you want to look up from jonnyguru.com, [h], techpowerup, and here (we didnt review that thing) to name a few.
Its an OLD unit is also part of the problem. PC's were powered different back when this thing was new. Now your PC is powered, mostly, off the 12v rail(s), so modern PSU's will focus their power on that rail. PSU's also degrade over time.
That said, if its working, I guess its working, I would just hate to see that thing, at worst, take out your PC or components if it craps out, regardless if the GPU you are upgrading to is the same or less power. I strongly encourage you to get a new PSU ASAP. Something like the Corsair CX430 is a great budget PSU.
Your picture does not work... not sure you followed those instructions homeh.
EDIT: Here is the label, dont worry about it

It has 20A on the 12v rail at most.. thats 360W... IF it can actually put that out CLEANLY, its ok, if not... potential problems. Overall its just a POS PSU man...and you are gambling with your PC by using it. I hate to say that but.. yeah...
