Can my PSU handle this Graphics Card?

[ShoMeso]

Computer: HP Pavilion p6-2330
Processor: AMD Radeon A10-5700
Motherboard: MSI MS-7778 (Jasmine)
RAM: 6GB DDR3-1600
HD: 1TB 7200rpm
PSU: 300w internal
12Va-12A
12Vb-16A

Will the EVGA GTX 750Ti graphics card work with this arrangement of power? It says it needs at least 300w on the website, but I've been told the box claims at least 400w and 20A on the 12V line. Is that just a safe estimate to avoid being sued, and can my PSU handle the 60w requirement from this card? Also, if it cannot, will only the PSU die (easily replaceable) or will the card/processor be damaged as well?
