Well, I am getting a HiS X1950 Pro AGP 256mb. My system specs currently are: Intel Celeron 2.7 Ghz (Northwood Core) 2 sticks of random DDR SDRAM 1 HDD (5400rpm) ATi 9600 Pro (currently) PSU, 250W. As, you can see the computer itself isn't very demanding/performing. I am having doubts about the PSU though. Using the eXtreme Power Supply Calculator I can make it so my system consumes less than 250W, WITH the X1950 Pro inside, around 237W is the number it gave me. Also, people suggest that you have to look at the 12v rail? I looked at it and beside it, it listed as 218W. So 218W can be the maximum consumption of the 12V rail right? I took that 218W / 12 = 18A? I am pretty sure 18A for just a video card is a bit too much? I mean, my vacuum cleaner is 18A. . Also, there is another system in my household which has a 300W maximum power supply. In this system, I have the X800XL and a lot of USB and CD drives. It is completely stable. With some research I found out that the X800XL peak load power consumption is roughly 49W. Moreover, the X1950 Pro's is roughly 65-70W. So basically another 20 extra watts. I will take this power supply if my current one doesn't perform. Also, I think the 12V rail has 22A on this one. Lastly, I know my system is quite crap and its going to bottleneck the X1950Pro. But, I will prepare for a upgrade real soon to better specs. Thanks in advance for reading my essay Regards, VeDz.
