Hey guys. I bought a pre-built system from Dell for a REALLY good price. It was waayyyy cheaper then building it myself, a definite rarity. Only problem is now I want to add a little more oomph but I'm not sure it will accommodate it. I want to add a XFX Radeon 5450 pci-e x16(with a low profile bracket or just remove the bracket altogether if need be). Do you think it will fit this slot?
Sorry for the probably obvious question, I'm just worried that since I won't be using the dvi/vga/hdmi slots on it(as I couldn't) that they will prevent it from fitting or that I need some other power cable.
Next off, do I need to upgrade my psu? It is a fairly generic Dell PSU 300 watt psu and I know I should but I'd like to hold off. I did both the newegg and the eXtreme Power Supply Calculator Lite calculator and they both said I needed 260-270 watts to run my existing setup and the new card(and that was with assuming 100% load which doesn't happen often). One guy on another forum with lots of experience told me I would be good, while I was asking an unrelated question.
Also, does anyone know of any incompatibility issues with a motherboard or BIOS, etc?
