help: your opinion about this computer

[manelf]

Hi, I want to build my first computer and I would like to have a good trade-off between price and some gaming specs.
So, after many hours of research I came with the following components and I would like to have your opinions about them:

Motherboard: ASUS P8Z77-V PRO LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard
CPU: Intel Core i5-2500K Sandy Bridge 3.3GHz
RAM: CORSAIR Vengeance 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Low Profile Desktop Memory Model CML8GX3M2A1600C9
HDD: Seagate Barracuda ST31000524AS 1TB 7200 RPM 32MB Cache SATA 6.0Gb/s 3.5"
GPU: ASUS GeForce GTX 650 DirectCU - 1 GB GDDR5 - PCI-Express 3.0

And I dont know which Power Supply and CPU Cooler are better according to the previous components.

Thank you very much,

You don't need the Pro motherboard. The P8Z77-V LK board is all you need. Replace the 2500K CPU with a i5-3570K. Replace the HDD with a WD Black. The stock CPU cooler is fine unless you are overclocking - otherwise get a Coolermaster Hyper 212 Evo. If you are not going to overclock, an i5-3350P is a better deal, it's cheaper and doesn't have onboard video. You need at least 400 watts, I'd get a Seasonic or Corsair TX/HX PSU. If you have any money left in your budget, get a stronger video card.
