Hello Bob_B, thank you for your good advice! I'm going to purchase the second one. Also, I think the second one will give me a better service than the first one. Thanks again! Cheers.

Nvidia Geforce GT-630 requires at least a 350W PSU and it relies entirely on the PCI Slot for power, meaning no extra connectors are required. So you need to use 350 Watt or greater power supply with a minimum of 20 Amp on the +12 volt rail.
