Ok i'm getting a new psu but the only thing that is preventing me from buying it is that is it enough for the GTX 460 Cyclone 768 MB GD5 ?

Here Are The PSUs Specs

-450 W Corsair VX 450
- 33 A on 12 V which i think will be enough for the GTX 460 cuz i've found a WEBsite that sad that the gtx 460 uses MAX 248 W
and if u do some maths u will see that 33 A on 12 V will be enough cuz when u multiply 33 by 12 it will be 396 Watt which is enough for the gtx 460 im getting that corsair PSU bcs of its low price 25 Euros

BUT i have a problem i can get that PSU but it's not new so my friend sas that i should not buy that psu bcs it can burn my pc is that true ?
if yes is there any way of testing this psu before installing it in the system cuz i will give the money to my friend to buy it cuz i work all day making music but if he is convinced that the psu will not burn my pc he will buy it to me so any kind of help would be usefull

For a system using a single GeForce GTX 460 768MB GDDR5 graphics card NVIDIA specifies a minimum of a 450 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 24 Amps or greater and that has 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 Corsair Enthusiast Series VX450 (SKU # CMPSU-450VX) power supply unit, with its maximum combined +12 Volt continuous current rating of 33 Amps and with one 6-pin PCI Express supplementary power connectors, is electrically sufficient to power your system configuration with a single GeForce GTX 460 768MB GDDR5 graphics card. You will need to use a dual 4-pin Molex peripheral to 6-pin PCI Express adapter cable for the second 6-pin PCI Express supplementary power connector on the graphics card.
