Have I got the right source for this Palit GeForce?

[xpxroot]

Hello everyone.
Been a fan for a long time and now I'm in need of help.

Just bought some new components and apparently my source(Power Supply) doesn't have the right amperage for my new graphic card.
I just have a no name source(Power Supply).
So I want to buy a new one.
Is this one http://www.cel.ro/surse/sursa-segotep-atx_450w-bulk-l/
good enough for my graphic card
http://www.shop.bt.com/content/uni2/documentation/82mn/palit_gt630_1024mb_neat6300hd01-1085f.pdf
Looking at the doc, saying I need 20 A on my 12V connector, I think its enough, but I can't be sure.
Thank you ALL for the time to read this, and possibly help me

EDIT: First of all guys/girls(if any here ) I am sorry for double posting, it said I am not allowed to edit that msg.

I took the readings of my current PSU
+3.3V - 24A
+5V - 35A
+12V - 16A
-12V - 0.8A
+5VSB - 3.0A

I have no idea what these do, but from the manual and these readings, I believe its the +12V that is not enough.

go for brands seasonic,corsair,xfx etc.
your psu is the component that decides the life of all other components you use.

do not compromise on it.

at least get 500w 80plus certified one.

right, i don't know what 80plus means? can't be the AMP can it? is that like a rating system?

I found this one.

On the +12V it would see it has enough. For my graphic card, what do you think?
