and your galaxy is single slot so you wont even need to do that
it should just go right in. If the regular bracket is on it, just unscrew two screws by the DVI port and place the low profile bracket on it.
i also have a hp slimline....
the power supply is only 160w
the galaxy geforce 9600gt requires 400w
did u upgrade ur psu??
if u did can u tell me where to get one?
the galaxy geforce 9600gt states it's low power @ 300w...which would still require a PSU upgrade. i'm only using it for a PC media center, and read the stock PSU would work ok for this application. so far so good.
