Buying new PSU need advice

[yuriythebest]

Right, my old PSU
AB POWER 480W ATX v.2.0
died.

After consulting the PSU guide stikied to this forum and some searching
I'm thinking of buying a
Cooler Master 650W, APFC, ATX - 2.3, 12см/ F - GX 650W (RS - 650 - ACAA - E3) Cooler Master
- it's listed as a good brand in the PSU guide

However I'm concerned about the following:
1. My old PSU was ATX2.0, this one is 2.3 - will it still work on my PC?
2. My old PSU had all these small misc ports but on their site they had images of all their connectors but said nothing amout these:

oh that's right **facepalm**

So what about the difference in ATX 2.0 and 2.3 will it work?

yes it will still work, google has lead me to believe that the difference between 2.0 and 2.3 is power efficiency

Excellent! so in that case unless anyone can see any glaring things that I missed and that would make my PC explode if I were to buy this I'll order it on monday!
