I just order HP 450t Desktop with Radeon HD 5770 GC. the PC comes with as 450W power supply and I want to know, if that has enough power to support the card. The HP site really can't tell me much. Ohter PC details. Intel i5 Quad Core. 12GB mem.

HP wouldnt sell the computer with the card if it wouldnt work. but yes, generally a decent brand 450w is enough for that card.
