I've had a Presario s4020wm for a while now and have upgraded it multiple times. I'm wanting to upgrade the gpu (again), but the psu is severly lacking anymore. Here are current specs: PSU-stock 200w cpu-AMD Athlon XP 2.0ghz chipset-VIA ProSavageDDR KM266 ram-1 GB edge hd- 80gb, 160 gb both western digital ide current gpu-nvidia gforce 5500fx I was thinking I need to upgrade the power supply and the video card both. If i just go ahead and replace both of those I a $150 budget abouts and I'm not sure about how psu's are chosen. I've heard you need to check size, rail speed, wattage, number of cables, etc etc and I just got confused. My other concern with doing upgrades lately is the whole computer overall. IDE drives seem to be a thing of the past and I dont have SATA connectors, The PSU is getting on the slower end, max supported ram is 1GB, you see where I'm going. Should I look at waiting or putting my money elsewhere? Any help is greatly appreciated!
