Suggestion for Required Power Supply

[lola99]

Suddenly my Thermaltake Toughpower 600W broke and I could not get it fixed. So in a limited budget I am badly in need of a poer supply. My PC configuration is:

Core i7 870
Asus Sabertooth P55i
ATI Radeon 6850 1GB DDR5
6 GB DDR3 Transcend 1333 BUS
1 TB Samsung HDD
DVD-RW
Creative X-Fi Titanium
USB3 Adapter
LAN Card
Thermaltake V6 BlacX

I have calculated my power requirement in this Asus link and it showed MInimum 500W is required.

If I buy a 500W decent PSU is it going to be enough? I have some options in my mind what will be the best for me or give me a better suggestion.. My options are given below. Thanks in advance..

1. Corsair 500CXV2 (500 W)
2. Cooler Master G 500W
3. Cooler Master Thunder 600W, 85per efficiency, Active PFC
4. Thermaltake 550W Light
5. Thermaltake 530W Smart

Depends what your budget it. If you can afford the 600W, just go with it. I always prefer to have as much headroom as possible.

Among these 5 I want to buy the Corsair 500CXV2 (500 W) but everyone is saying if you got more juice I mean more WATT it is better for you. On the other hand there is efficiency. So, I was going for Thermaltake 730W Smart but everyone suggest me for Corsair or Cooler Master. I was sure for Corsair 500CXV2 then someone told me about 'Cooler Master Thunder 600W, 85per efficiency, Active PFC' . It has 85 percent efficiency, so I thought this will be better for me in 84$ because I was getting more watt and the Corsair was costing me 74$. But now nobody is suggesting Cooler Master even though the matter of watt. I actually do not understand what to buy..

Actually I cannot have that one I have to choose among these 5 or Thermaltake 730W Smart or Gigabyte 580W..
