Welcome to Tech-Forums!!!
The power supply is too much for your system, but I see you're going to eventually get a dedicated graphics card. But I would suggest this power supply instead:
Newegg.com - Rosewill RP500-2 ATX12V v2.01 500W Power Supply 115/230 V CSA, UL, TUV, FCC - Retail
What will be the purpose of this computer?
You also, do not need those wires, as the motherboard will come with them. You're also missing RAM. So here's a suggestion:
Newegg.com - G.SKILL 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory - Retail
