I'm going to get a new graphic card and I don't have much budget. My question is whether my system is able to support Nvidia Geforce GT 630 4GB.
Operating System : Windows 7 Home Premium 32-bit (6.1, Build 7601) Service Pack 1
Processor : Intel(R) Core(TM) i3-2100 CPU @ 3.10GHz (4 CPUs), ~3.1GHz
Memory : 4GB RAM
Motherboard :H61M-S2P(GIGABYTE)=>(http://www.gigabyte.com/products/product-page.aspx?pid=...)

This is my PSU model
power-logic-power-supply-magnum-230-450w-plg-250w-castleit-1104-21-castleIT@13.jpg

it is written there pure/real power is 230w and max/peak power is 450w, what does it mean?
can it support the nvidia gt geforce 630 4GB?
