Corsair CX400 vs 450?

OK, looks like the only difference between the Corsair 400 and 450W PSU's is 30A vs. 33A on the 12V rail. Right now I have an OCZ 450W PSU (26A / 12V) but it's about 5 years old so I'm looking to replace it "just in case".

Existing build works just fine with the OCZ (Athlon 64 X2 4200+, 89W rating), Abit 939 mobo, nVidia 9600GT 512MB, 2GB DDR400, 320GB HDD, DVD, etc.

I'm guessing the new Corsair 400 would be fine with my new parts on order (Phenom II X3 720 BE, 95W rating), Asus AM2+/AM3 mobo (AMD 770 - no onboard graphics), 4GB DDR2-800, same 9600GT 512, same HDD and DVD.

Thoughts, comments? For $39 after rebate it seems like cheap insurance. I might overclock the CPU slightly but the $20 difference for only 3A more on the 12V rail doesn't seem like a deal killer for my system load.

Thanks in advance everyone!
 
If you have no plan to upgrade anything, then sure, the 400W is sufficient.

It looks like the newer Corsair PSU will be providing you with more power through the 12V rail, so it should give you more headroom than the OCZ psu you have.
