Is Antec VP650P 650 Watts good enough for my config

My PC build:

Intel i5-3550
Gigabyte GA-H77M-D3H Motherboard
Corsair Vengeance DDR3 8 GB (1 x 8 GB)
Asus HD7950-DC2T 3 GB GDDR5
WD Caviar Blue 1TB

I will be using the PC for a lot of gaming.
So would Antec 650P 650 watts be sufficent to meet the power requirement.

Ok. So now I have decided to go for Gigabyte 797OC-3GD as the price difference is not much between it and Asus HD7950. Will my Antec 650P still hold good?

The only review of that unit I found was in Chinese which does not translate well but the general gist is that the PSU is a solid unit for the price point but that it may cause issues if overdrawn (very unlikely with your current setup). I don't think you'll have any problems using it.

For a system using a single Radeon HD 7950 graphics card AMD specifies a minimum of a 500 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 30 Amps or greater and have at least two 6-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most critical factor.

Overclocking of the CPU and/or GPU(s) will require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

The Antec VP Series 650W (VP650P), with its maximum combined +12 Volt continuous current rating of 50 Amps and with two (6+2)-pin PCI Express supplementary power connectors, is way more than sufficient to power your system configuration with a single Radeon HD 7950 graphics card.

The ASUS HD7950-DC2T-3GD5 is PowerTune Throttled to 216 Watts so it shouldn't draw more than 17 Amps from the +12V rail(s) even when you run Furmark.

Thanks a ton. I am convinced i can go with this PSU now.
I do not intend to overclock in the near future.
