should be fine remeber a high end overclocked cpu and remainder of system can use between 250-300w then you have to add what ever the graphics card draws to that.

system =300w
gpu= 300w

you still have 150w head room so should be good to go.

ive re used my old alienware case and psu (2006) no problem its now powering 2 660ti and a 960 @ 4.0gig

Dell make great PSUs and that has 58a on the 12v rail. Even accounting for the age it should be fine :)

that is individual rail shit though....some are okay/decent but the single strong 12v rail is a superior design...
