I have an HP Workstation XW4100 that has a 280 watt power supply. I want to upgrade the graphics card but the lowest I can find is one that says it requires 300 watts. I've looked at a lot of graphics cards and some of them say something like this:
300 watt or greater power supply (recommended)
I'm curious about this "recommended". Does that mean a 300 watt graphics card will run on a 280 watt power supply?
I actually bought a 350 watt power supply but it appears to be the wrong size for my pc. It is slightly smaller than the one I have and the screw holes don't line up. Do I have to buy the same brand power supply for it to fit? Also, can I just up the power supply on my computer without frying it? I'm a bit of a novice so sorry if my questions seem a bit rudimentary.
Here is what I have:
Hipro 280 watt
NVIDIA Quadro NVS
Here is what I bought:
JeanTech 350 Watt
NVIDIA GeForce 7 (7300T)
Thanks very very much!
