I am trying to upgrade my new machine but I want to do it myself. This is my 1st attempt at building system. After carefully reading reviewing feedback and my budget I have decided to select the below listed components. Can anybody let me know are they compatible or not?

Transcend 64 GB 2.5" SATA Solid State Drive 

Asus GeForce GTX550 1GB DDR5 ENGTX550 TI DI/1GD5 Graphics Card 

Seagate Barracuda 1 TB HDD Internal Hard Drive 

Cooler Master eXtreme Power Pro 600 Power Supply 

Intel Core i5 2500K Sandy Bridge 3.30 GHz 95 W 4 Core Desktop Processor 

Intel DX79TO Motherboard 

Corsair CMZ8GX3M2A1600C9 8 GB DDR3 SDRAM 1600 MHz Dual Channel Kit Desktop Memory 

Sony AD-7260S-ZS Internal DVD Writer - Black 

Cooler Master Hyper TX3 EVO Intel CPU Cooler 

Cooler Master Elite 335U Cabinet 

LG E2051T 20.1 Inch SuperSlim Monitor 

Is any of these hardware components incompatible with I5 2500K? If you have any other suggestions for selecting any other harwdware that can boost up my performance or lower my cost while having the same performance, please suggest. But my primary questions is whether they are compatible or not! Any help is appreciated.

Thank you.
