First build, 800-900 $: Is this a decent gaming build?

[MadHeadNL]

Hello everyone, I am going to build a pc for the first time in my life, and I was hoping I could get some help with this build, if it's a good build for gaming purposes, and I also hope that you guys can hook me up with a good power supply. If you think you can improve my build, give me advise, or help me in any way, please don't hesitate to reply.
So I filled in this form, if you need to know more details, please ask, I will try and answer as fast as I can.

Approximate Purchase Date:
In a couple (3-4) months

Budget Range:
As the title says, 800-900 $

System Usage from Most to Least Important:
Gaming

Parts Not Required:
This is a list of the parts I currently am looking to buy:

CPU:
Intel Core i5 3450 3.1 GHz

Motherboard:
MSI Z77A-G45 LGA 1155 Intel Z77

Graphics Card:
ASUS ENGTX560 DC/2DI/1GD5 GeForce GTX 560

RAM:
G.SKILL Sniper Low Voltage Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)

HDD(mass file storage):
Western Digital Caviar Green WD10EARX 1TB IntelliPower 64MB Cache SATA 6.0Gb/s

SSD(OS and apps):
OCZ Agility 4 AGT4-25SAT3-64G 2.5" 64GB SATA III MLC

Aftermarket CPU cooler:
COOLER MASTER Hyper TX3 RR-910-HTX3-G1

Case:
Sharkoon T9 Value Red

So all I need is a PSU/Power Supply, but I had no idea how I should choose between power supplys, which were of good quality and all those things you've got to bear in mind.

Preferred Website(s) for Parts: I use tweakers.net, but this site is only for shops in my country. I just included links to Newegg so that you guys would understand what it said, should you need/want to read the specs on it, or have to do something else with it.

Country:
Holland

Parts Preferences:
As I said earlier, I only need a power supply, but I don't have any experience what so-ever with PSU's, so I don't think I really care, as long as it's a good power supply.

Overclocking:
Yes
SLI or Crossfire:
No
Monitor Resolution:
1980x1080
Additional Comments:
I already have peripherals(mouse, monitor, keyboard, dvd-reader) and an OS(Windows 7)

Thanks in advance for helping me out!

with power supplies, you want one that is at least bronze certified (80% efficiency) and is from a reputable brand. any of these would do

600w would be about right to leave you plenty of spare without being overkill for your system
