Delpheno

Okay so I got a terabyte hard drive in the mail today. (Opinions? I heard the fail rate was high, but I'll take the risk.)

I think I should tell you the scenario first. I have a Dell 530s, Celeron 450 2.2ghz, 250W power supply unit. A 320gb hard drive in one bay. My plan is to have the terabyte in the second tray. I have a low-profile graphics card that I installed two months earlier, I'm not sure how much watt that thing is taking up.

My main concern is the power supply unit. With 250W, a low-profile graphics card, and a new terabyte hard drive being installed, should I worry about my PC parts frying up?

I don't have the SATA or the power cords. I plan on taking out the cords from the SATA DVD burner and use it for the terabyte. With the DVD burner out of the picture, should my wattage be fine?

There are also extra plugs for the power and sata cords in the motherboard. If I plan on getting the cords, I would have a low-profile graphics card, two hard drives, and a DVD burner running. Should I worry this setting?
