Hello. I would like to upgrade my HP Pavilion p6820 computer by replacing its stock Bestec ATX-250-12Z 250W power supply with a more powerful one, as it is not powerful enough to power the Zotac GT 710 graphics card that I installed. The power supplies from the Bestec ATX-300 series are very enticing, however I do not know if they would actually be powerful enough to power a Zotac GT 710 graphics card, as that's a really modern, really powerful, power-hungry card.
So far I have found three different models on ebay.
ATX-300-12E
ATX-300-12EB3
ATX-300-12Z
By looking at their label and comparing the specifications to the ones of my ATX-250-12Z, do you think that any of these power supplies could work? The 12E looks like it's the least-powerful. The 12EB3 is odd because compared to the other ones it has two 12V lines. Is the 12Z the best choice?
Sometimes, I run three hard drives in this system. Other than that, I run a terrible USB diskette drive (aren't they all terrible?), and sometimes a capture device and added I/O ports with a parallel, serial or firewire card. Other than the hard drives, I doubt that these things draw much current.
