yeah, 250 ps would eventually get
burned out.

you can go with the 500 watt power
supply, but it may be more power
than you need and a waste of money.

my suggestion is that if you don't
need the extra power, then go with
something around 400 watts which
runs about 20 or 30 bucks.

basically anything between 250 and
400 watts would suffice for a regular
computer with two dvd drives.

That psu is a really cheap one. And the other poster who told you to put in
a lower power cheap psu is 100% wrong. A decent psu should run you $50+. A
cheap psu will land you right back where you are now. If you're in the US,
NewEgg.com has some really good deals on psu's. I just got a 400W Corsair to
keep on the shelf for $50. Bought a 650W Corsair for $100 for a client,
marked down from $169. (You don't need such an expensive one.) I would not
buy a $20-30 psu. Don't skimp on quality when it comes to your psu.

Thanks in advance for your help.

For some power supply failures, the motherboard gets
damaged too. So there is a small possibility, that when
the power supply failed, it caused more damage. The
supply with the worst reputation, is a Bestec 250W unit.
But Deer as a brand name, isn't much better.

You want to verify that the old supply was a standard
ATX design. So that plugging in the new supply is not
going to cause a problem. You can compare to the wire
colors listed in the ATX specs. The first spec, is from
an era when the supply had -5V. The second spec, removes
the requirement for -5V. The third spec, switches the
main power supply connector to the 24 pin format.

http://www.formfactors.org/developer/specs/ATX12V_PSDG_2_2_public_br2.pdf (page 37)

Since your Chiefmax replacement has a -5V rail, that will
cover cases where a motherboard has a dependence on -5V.
The specifications for ATX power supplies, removed -5V
and the associated pin, some time ago. But if the old
supply had -5V, then including it as a requirement for
the new supply, might not be a bad idea.

I also notice there is a Chiefmax 550W Version2 supply,
and it has removed -5V from the output. That would
not be a problem for modern motherboards. When a seller
advertises the original one, they could swap a V2 on you
when they ship it. I got that kind of treatment when
I bought a certain Enermax supply, and a V2 version of
supply was provided instead. Lucky for me, the replacement
worked anyway.

So I'd start by reviewing the colors and the connectors
on the original Deer, to see what you're dealing with.
