No both are crappy psus get this one : http://msy.com.au/product.jsp?productId=8639 or http://msy.com.au/product.jsp?productId=9908

Good brand and quality psu and it's cheaper.

But will 550 watts be enough for my build?
Cpu: FX 6200 3.8ghz
Gpu: Sapphire HD 7950 3gb
motherboard: MSI 970A-G46 AM3+
Ram: g-skill 8gb
HDD: Seagate barracuda 2tb 7200 rpm
Also i might add some extra fans

That system will not draw more than 450w full load. It still leaves a margin and the antec vp550w can deliver the full power @ good temps.
But if you want more juice : http://msy.com.au/product.jsp?productId=8640

Hi - dj is correct - Antec PSU's are better quality than CM or TT,
slect one of those he linked depending on your budget.

For a system using a single Radeon HD 7950 graphics card AMD specifies a minimum of a 500 Watt or greater power supply. The power supply should also have a 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!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most critical factor.

You may find power supplies on the market that supply more than enough Wattage to run the system. However, some of them lack the Amperage capacity on the critical +12 Volt rail, which is necessary to properly power the critical components in the system (i.e. CPU and GPUs). This is the reason why graphics card manufacturers overstate the power supply wattage, usually by at least 50 Watts, to take into account those power supplies that have the weaker +12 Volt rail(s).

The Antec VP Series 550W Continuous Power (VP550P), with its combined +12 Volt continuous current rating of 45 Amps and with two (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single Radeon HD 7950. This PSU has a 2 Year warranty.

The Corsair VS Series VS550 550 Watts (CP-9020050-WW), with its combined +12 Volt continuous current rating of 42 Amps and with two (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single Radeon HD 7950. This PSU has a 3 Year warranty.

As you can see both PSU's are more than sufficient to power your system configuration and handle any overclocking and the addition of any extra cooling fans.
