Hello,

I was on eBay trying to find a Radeon HD 7750 to buy for a fairly low price. I am wondering if this card will work with my system: http://www.ebay.com/itm/XFX-GHOST-RADEON-R7750-1GB-FX-775A-ZN-7750-PCI-e-video-card/221474766499?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D20131003132420%26meid%3D7943375033549700707%26pid%3D100005%26prg%3D20131003132420%26rk%3D4%26rkt%3D6%26sd%3D271522789994&rt=nc

I have a Dell OptiPlex 755.

Intel Core2Duo 3.3 Ghz
300W PSU
2GB Ram

According to the specifications sheet the 305W PSU's 12v rail combined is 264W/22 Amps.

(Spec sheet: http://www.dell.com/downloads/global/products/optix/en/opti_755_techspecs.pdf)

The suggested requirements for a 7750 system is 16 Amps on the 12v rail, so that seems fine. the only thing you have to worry about then is likely the dimensions of the card & it fitting in your case. So get the tape measure out & check them against it.

And the mini tower version that uses, 305W, which you say you have, has the correct PCI-E x16 interface.
