Dual power distribution suggestions

post #1 of 3
Thread Starter 
Hi all,

First post. I am not overclocking my pc, but am adding a second power source, referring to the tutorial in this section on how to. Let me give you my sytem specs, and the power supply watts, and ask for assistance on how I should distribute the power to my components for best results.

Pentium4 3.0Ghz Hyperthread enabled.
(2) 1 gig sticks of Ram
(2) Hard drives (nothing fancy)
(1) Dvd drive
(1) Cd writer drive
(1) POS floppy drive
(1) Nvidia GeForce 6800 GS Vid card
(1) Soundblaster Sound card
(2) Cooling fans, 1 on processor, 1 on case.

I have an existing 350 watt power supply, and have a small 200 watt that I want to add to the system.

My questions are (1) Is this enuff additional power? (2) What would be the best way to distribute the power detween components for best performance? (3) If I added a couple of extra fans, would that be needed, and where should they factor in to the power supply equasion?

Thanks for help

hmmm.....question.....why go through all the trouble of doing that, just get a 550 watt PSU......When you use two PSUs ion one computer, you can run into stability issues because diff components are getting differing amounts of power....i would go with the 550W

He didn't ask IF he could do it, but rather HOW he should do it. I do the same thing buddy, but I use auxillary Sunbeam NUUO PSU (yes, i have two), but with the second one, that is, the one that is added as auxillarry, for it to work correctly, you can either do the ghetto way, or you could make it clean and void your warrenty. Your call, i chose to void my warranty, sice the sunbeam isn;t toooo expensive.

The ghetto way is to just bridge the green wire on the p4 connector with a ground (black) wire on the connector. The cool way to do it, is pop open the psu case, snip the wires goign to the p4 connector, except for the green and one of the blacks, solder them together, close it up, and voila, you have a test/auxillary psu.

Now as to the way it should be hooked up, i would use your ore powerful PSU to power your power-hungry components, IE mobo, VIDcard, opticals. Use the auxillary to power the HDDs and the lights/fans/whatever else you have stuffed in there. Make sure you have a relay though for your aux PSU, or it has a toggle switch, or it will run non-stop......

Happy modding
