Powers supply

My computer had a 150W power supply.It went kaput. I have come across
a 250w power supply.

Is it ok to use 250W where I originally had 150W.

Also how does one know?

The numbers seem pretty small. I use a 350 and a 500 in my two
computers. I'd suggest a good 300w minimum.

Bigger won't hurt. Smaller will choke.

And on what basis do you arrive at this power estimate when there's not one
clue as to what comprises his system?

Bigger will 'hurt' if it don't fit in the hole and at 150 Watt it very well
could be a SFX form factor micro-ATX PSU as found in gaggles of E-Machines
and HP mini-towers.

Then I suggest you reply to the OP warning him of the size difference
between SFX and ATX form factor supplies, and how to recognize the two.

The answer given was correct in answering the OP's question about *power*,
not form factor.

Just check out the plugs on the old power supply, and make sure
that match the shape of the plugs on the new power supply. As long
as it plugs into your motherboard, you should be fine. Bigger is
better, when it comes to watts.

It is perfectly fine to change the P/S wattage. What is very
important is that there is enough power for all your peripherals. A
150W power supply is quite small in today's computer. A higher
wattage P/S does not mean it will burn out your components--it must
still provide the correct voltages.

Actually, no, the *whole* 'answer given', which you snipped out, was not
'correct' with respect to power.

John:

Yes.

Despite what some people claim, bigger is not better in the power supply
department. There are different sizes of power supplies and it would be
pointless to buy a power supply that will not fit in your case. It would
also be pointless to spend the extra money on a power supply that is way
too powerful for your machine. If the original only required 150W and you
haven't significantly altered the machine, the 250W will be fine.

Everybody's a critic. A few weeks ago, I posted saying that it was
foolish to over-power your computer, because a larger power supply
will run hotter and noiser. I got jumped on and told in no
uncertain terms that a larger power supply would run cooler and
quieter. This being so, why not over-power your box up the wazoo?
If you make the power supply large enough, maybe it will be
completely cold and dead silent. :-)

If part of it was so incorrect (in regards to the OP's question of power)
why didn't you address it, along with the size issue?
