Describe your case ventilation system. IE How many fans blowing in versus blowing out, their size and rated velocity, etc.
Case ventilation can have a crucial impact upon how warm your PSU runs, as well as how hard it is working.

The PSU should not be hot with the PC turned off, assuming we are talking an ATX motherboard and ATX compatible PSU.

My system is :
abit kd7 (non raid) (kt400) bios version = b8
athlon xp 2100+
dvd =asus
cd recorder=plextor 24x10x40
hard disk: western digital 7200 80gb
video card= tnt2 ultra 32 mb by creative
and the psu is a chieftec 360W max load.(+5 v,+3.3v =220W) (+12v=204W) (-12v=9.6W)
(+5vsb=10W) (-5v=1.5W).
Is the psu compatible with the motherboard or the other parts?
Another question is: can this psu afford my system?
Thanks for replying me

Well, you have an ATX motherboard and an ATX PSU so they should be.
If the PSU delivers those rated outputs, it should work. Nothing is for certain except death and taxes."

You're welcome. Good Luck and let us know how you fare.

The Pcu has a switch at the back of the box .when this switch is on and the pc is off ,the pcu is hot.More over if i push the caps lock botton when im in windows the light of the keyboard is on.When i close the pc by clicking on "the turn off" the pc and the fans stop, but the light of the keyboard continues to light.IF i switch off the pcu then ok are all off.When i switch on the pcu from the botton that is at the back of the pc the 3 lights of the keyboard are lighting for 1 sec and then are all off except the pcu that it is hot after some time
IS this a problem of the motherboard or of the pcu?

It's actually PSU, not PCU!
My (generic) 300watt psu used to get a little warm to the touch when off, but with the switch on, but not 42c.
The switch can normally be left on 24/7 - since all ATX (like your) PSUs provide a little bit of current all the time, to let you turn your computer on.
When your computer is actually running, does the PSU get colder, or does it stay about the same?
Try sending Chieftec an email asking about this problem..
Hope that this helps!

The directions for one mobo said that if the BIOS was configured for keyboard power-on, the amp draw in suspend mode would be several times higher, up to 0.7A, which is about 5W (assuming 70% PSU efficiency). I don't know if that's enough to make the PSU reach 42C with the fan off, but you may want to reconfigure the BIOS to disable keyboard power-on to see if it makes things cooler. I don't think it will because I'm testing a PSU in suspend mode right now with 0.85A, and it's stone cold, and the 150W load resistor is barely warm.

If it's 37-38C even an hour after the computer has been turned off, then I don't think that's normal, but I'm no expert.
I don't know who makes Chieftec PSUs, but I read somewhere that they're Channel Wells (part no. has "CWT" in it, yellow plastic tape on transformer tops says "CWT"), and the PSU I tested was a Channel Well.
If an electrolytic capacitor in your PSU has gone bad, then that could make the transistor or diode connected to it far, far hotter than normal, and I had one on a mobo reach about 100C
