I have a Gateway DX4300-03, it came with only a 300 W power supply (Even though the video card is a ATI Radeon 4650 and came the PC as well). I am going to upgrade my Video Card to A XFX Radeon 4850 (its in the mail and should arrive in the next week). I need to get a new power supply for sure, but im not sure how to tell if the new power supply will be compatible with my system and my new video card. If any information about my PC is need just ask. ANY HELP WOULD BE APPRECIATED.
these are obviously bigger and better, and therefore you have a better chance of using them again latter. its up to you. pay less now, and maybe not be able to use it later (maybe, but you still might) or better now, and have a better chance of using it later.
