I was told that the reason that my Radeon 9800 Pro 128 MB is giving me less FPS than my GeForce 3 (yes, I've reformatted twice, installed service pack one, downloaded all the updated drivers, ect., so I know it's a problem with my hardware) is that my PSU is only 250W and probably has a really weak 12V rail. I have a Pentium 4 Willamette 2 GHz, 768 MB RDRAM, Radeon 9800 Pro 128 MB, 40 GB HD... all running on a 250W power supply. So, I went shopping for some power supplies.
Came across an "Achieve AX550 550W Dual Fan Switiching Power Supply" on sale for $20 (reduced from $30) on the website http://www.topmicrousa.com/achieveps550.html.
The description of the voltage rails are as follows (it doesn't say it on that site, but I found it on a different site):
+3.3V 40A
+5V 46A
+12V 24A
So... does this look good for $20? I mean $20?!?!? That's freaking cheap! I was looking at other 550W powersupplies with around the same voltages and they were all the way up to $100-$200. What do you guys know about Achieve Power Supplies? Reliable, cheap, ect?
Do graphics cards AND CPUs really use the power on the 12V rail... and what do you think my needs are for my system (mentioned earlier in the post)?
