Power Supply: Help!

Hello, I was just wondering if the Power Supply of a computer really mattered all that much. I wanted to know if it has any affect on the performance (how fast/slow) your computer will run? I also would like to know what would be a good Power Supply for a computer running these parts:

GIGABYTE GA-MA790XT-UD4P AM3 DDR3 AMD 790X ATX AMD Motherboard
Western Digital VelociRaptor WD1500HLFS 150GB 10000 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive
AMD Phenom II X4 955 Black Edition Deneb 3.2GHz Socket AM3 125W Quad-Core Processor
CORSAIR XMS3 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Triple Channel Kit Desktop Memory

Thank you.
