I am not an electrical engineer, and I may be wrong here, but I don't think
that's correct. The wattage rating of a power supply is not how many watts
it puts out, but the *maximum* number of watts it *can* put out. The actual
number of watts is determined by the needs of the equipment connected to it.

Well I am an electrical engineer...and you are correct in that a larger
capacity supply
will not draw any more power...it merely has the capacity to supply more.
If it has a variable speed fan however...it *might* be turning slower than
the one in the old supply.

Thanks for the confirmation.

The manual states that it has two fans-intake & exhaust. That the intake fan
monitors the system temp & adjusts it's' speed accordingly. If I connect a
certain pin, which I did not, I am suppose to be able to observe the fan's
rpms. Also, the exhaust, exterior, fan remains off until until the power
supply recognizes it is needed. This also contributes to noise suppression.
My main concern is whether, or not, 50-51c is an ok temp?

Depends on what CPU you're running. On the AMD site, you can look up
optimal temp ranges for the processors they make. I imagine the same info
is available somewhere for Intel processors as well.

And if you install a bigger powersupply in a computer that needs one and it
draws more...it won't generate more heat?...sure it will.

RE: the debate over wattage & temp. I'm, obviously, a novice but I think you
all may be right. I installed a more powerful UPS but I added no new devices
which may need more power. I did so with future considerations in mind. As
of now I think Philo & Ken are correct-the increased power is there only if I
need it. And if that becomes the case & more wattage is required then I
think a higher temp. reading may be justified( as Crash inferred). But as of
right now, which was my poorly worded original question, I don't understand
why the temp has increased a few degrees-unless the fan does rotate more
slowly.
As always, I appreciate everyone's help but Sharon-if I wanted to refer
to a manual somewhere I would have. I figured input from knowledgeable
indiduals would be simpler &, frankly, more fun. Thanks!

Alan, you're welcome but I addressed only this portion of your question:

> My main concern is whether, or not, 50-51c is an ok temp?

None of us can answer that without knowing what processor is in use.
Anyhow, enjoy your new hardware upgrade!
