will a R9 270x run on the coolermaster gx 450w?

I have the coolermaster gx 450w and i want to know if i could power one of these... the rest of my system draws about 150 watts of power...

For a system using a single AMD Reference Design Radeon R9 270X 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) may 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 Cooler Master GX-450W (RS-450-ACAA-D3) power supply unit, with its maximum combined +12 Volt continuous current rating of 35 Amps and with one 6-pin PCI Express supplementary power connector, is electrically sufficient to power your system configuration with a single Radeon R9 270X graphics card. You will need to use a dual 4-pin Molex peripheral to 6-pin PCI-E adapter cable to handle the second PCI Express supplementary power connector on the graphics card. This PSU has no margin for overloading. A fraction of a Watt over 450 Watts will trigger its Over Power Protection (OPP) circuit.

http://www.tomshardware.com/reviews/radeon-r9-280x-r9-270x-r7-260x,3635-18.html <-- shows a benchmark of certain configurations and the power consumption. It draws about 150 watts at a average high for what I can assume you would be "pushing" it to.

I would go up slightly in the wattage department andgo with a more reliable brand.

well i want to ask whether a Cooler Master Thunder 500 watt can handle a sapphire r9 270x dual x or not? Cooler master thunder 500 have 2 12volt combined power of 45 AMP.

I am about to prepare a rig with the same gpu...
Got fx 6300 in line..
And i am going with corsair 450w psu with 85% efficiency...will it be sufficient?
Or should I consider going with a r7 260x?
