Connecting Two Power Supplies in one PC

Question

Hello there  :hypecrite:
Will someone help me on how to connect two Switching P/S in one PC (If it's possible)?
I tried using two P/S in my old PC and it's working just fine. However, the problem is that I cannot switch them on simultaneously because the one is connected directly to the motherboard and the other, I just used a simple switch to turn it on.
Also, please check my P/S for this PC if it's OK.
Thank you and more POWER!!!

Hello again :hypecrite:
Thank you for your support guyz.  I would like to tell you that you are all correct.
I think it's time for me to stop fooling aroung, experimenting things, too.  And to trust the verdors instead.  I looked for the psu brands that you all mentioned and it turned out my pockets could still handle such a cost, eventhough it costs twice as much as the psu that I have right now, but as long as it's dependable.
And about the problem with my CPU's temperature that I posted last November 12, 2004 (MSI KT4A-V with S/PDIF out and Core center), AMD support center finally replied to me and told me that my temp is OK but not to go above 70C.
Below is my inquiry to AMD and their reply:
My inquiry:
Dear Sir:
   I would like to ask what is the NORMAL operating temperature of Athlon XP 2400+ FSB 266 model 8?  
   When my PC is at idle, my CPU temp reading is 60C and during full load, it reaches to about 66C. It doesn't have any problems though (such as random reboot) but I'm a bit concerned of the temperature reading.  Some people say that it's a bit TOO HOT  for comfort. Still others say that it is OK.  What do you think?
  I have read your post on MAXIMUM operating temperatures of Athlon XPs but not the recommended NORMAL operating temperatures.
  And also when I turn  the BIOS CPU core voltage to AUTO mode the default is 1.575V. My friends said the minimal operating voltage of 2400+ is 1.650V. Is it OK to just leave it to default?
Thank you very much

Dear Guillem,
Thank you for contacting Asian and Pacific AMD Technical Support Centre.
I can confirm that the temperatures ranges from 40° - 55° C  in moderate usage and with a higher workload around 65° C, but never over 70° C.
What the correct voltage is concerned there are three models of the Athlon XP 2400+. If you have the CPU with the OPN AXDA2400DUV3C the
voltage should be 1.60V otherwise it is 1.65V.
It seems your system would overheat dangerously when set to the right voltage. I would suggest, you do check if the heatsink /fan is installed
properly.
You may find a different reading after upgrading your BIOS.
* Please make sure to download the right BIOS version for your motherboard.
Then, please, make sure that your processor Athlon XP 2400+ is configured in BIOS as follows:
-          FSB speed to 133MHz (It is a bidirecctional bus, the full speed would be 266)
-          CPU multiplier of 15x
-          CPU voltage of 1.65V (1.60V if OPN = AXDA2400DUV3C)
With these settings the clock frequency of the processor should be 2000 MHz.
And finally you can test the CPU on another system to establish if the processor or the motherboard is responsible for the problem . If no other system is
available to you then ask your retailer/reseller to test it for you.
Given the case that the processor is faulty, we inform you that the PIB processors (box processors) have 3 years warranty, whilst OEM processors (tray processors) have only one year. In both cases the first year is given by the reseller and the PIB processors second and third years are served directly by AMD.
If you have any further questions, please, do not hesitate to contact us again.

Yesterday, I increased the CPU voltage to 1.60V (from the default of 1.575) and my temp reading was reduced to 50C at idle (from an idle of 60C) and at full load to 60C (from a full load of 66C).  I was not expecting this though.  I was expecting that my CPU's temp will increase further.  But this is what happened. I guess the RIGHT THING should be the RIGHT THING.
Tomorrow, I will buy a new psu with the brands that you mentioned and I hope that my PC's stability and performance will increase further.
Again thank you very much for your support and all.
