[dolphinv]

Specs:
Hp s5780d
Motherboard:MS-7613 (Iona-GL8E)
Intel Core I3 550
AMD Radeon 6450 (Spoilt, Removed it ALREADY)
220w PSU (Dimensions: 200mm x 85mm x 53mm (7.9 x 3.3 x 2.1 inches))

Is it possible to upgrade the graphics card to a gtx 750 or 750ti? Given the official specifications listed a 220 W PSU. Any other graphic cards to recommend? Also is there any bios restrictions implemented by hp for installing third party graphic card.
Thanks. Any help is appreciated

Get a Zotac GTX 750 low profile variant for $189. The 220W PSU should be able to support this GPU as the GTX 750 uses very little power during its operation.

Normally, very few OEMs will put a BIOS hardware whitelist in their desktops, so you should generally have little issues in replacing your GPU.
