Correct Power supply

[SANTANDER]

Can someone professional tell we what power supply is required:

1)
Celeron 2.66GHz
Audio, video on board
RAM 1GHz
HDD1 - 80Gb
HDD2 -160Gb
DVD-R
Floppy
Network card

2)
PIII 866MHz
Audio, video on board
RAM 512MB
HDD1 20GB
HDD2 40GB
CD-R
Floppy
Network card

There is few online power-supply calculators, but I am not sure they show
correct info.

You would be better off posting to a hardware newsgroup. It's not an XP OS
issue.

if you are looking at buying from a store, have them verify their PS is adequate.

remember to max profit, it would be just adequate.
not much extra for upgrades.
should have 350-400 watt PS, minimum

never mind the virtual spanking issued by our resident nanny.
it only hurts for a never while.

<snip - list of a bunch of generic devices>

This group is about Windows XP which is an operating system. You are
asking a hardware question, so your post is off-topic.

As to what power supply you need, that depends on WHAT motherboard you
have that you never bothered to mention (and also what video card(s) you
have).

As for wattage if that is what you really meant to ask, the only way to
know for sure is to get the specs on each component and add up their
peak power usage. Peak is momentary, like when the devices are first
powered on, but the PSU still have to supply that peak load when they
all get powered up together. It's a good bet that every component you
have has a web site by its maker to go find the specs.

How can you be sure that you're getting correct info here?

Ask this in a hardware group. Better yet, ask a working technician.

Can't say. It depends on what each of these things require. Most people
just get the power requirements for each device and add them to get the
total. Then we add some for future growth.

That's too complicated.

From the list of power supplies that meet the mainboard's minimum
requirements, choose the most power you can afford, and stick with an
established brand.

Look at the specs for computers that retailers are selling. You'd
probably be surprised at how light their power supplies sometimes are.

The average computer user should be fine with a good quality 400W
power supply... and it might very well be more than they need.

Gamers and over-clockers might want to go for more.

Can't be done based on the information provided.

You need to know the +12, +5, 3.3 volt requirements for all concerned,
including the motherboard. Add them up. Add any for potential add-ons.
Add minimum 10 per cent for loss over time. Find the power supply that
meets or exceeds those figures.

If any response that is spouting total power supply wattage, no clue about
the subject. And has no clue about differentiating amperage availability on
each voltage leg given different power supply with same overall wattage
rating. Ignore the response.

It seems, there is a technical way to test a consumed current precisely. It
possible to do a small trick - to connect PC to the electrical socket not
directly, but via the ammeter, .i.e. join one pin of male power plugs with
ammeter, then connect ammeter 2nd contact to one hole in the socket(to
connect in break an electrical circuit). Then PC power-on and check ampers.
Then P = I x U..

But not your way when it comes to PCs.

The power supply will draw the same at all times. It's wattage rating
is what it is capable of providing to the PCs components at the
various voltages they require.

That's too complicated.

I wasn't trying to make it simple. The OP is looking for a very precise and
complicated way (over precise and unnecessarily complicated in my opinion).
So, I gave him one.

When I build my own, I get the biggest power supply that will fit my case.

Not reasonably feasible with block connectors used for power supply output.
This does one thing, checks amperage usage by all the devices on that
circuit. It does not validate potential amperage output on a given voltage
leg. Means nothing if you're building a PC as you need an adequate power
supply first.

There are small clamp-on type ammeters available that don't require opening
a circuit.

OK, if do not complicate this question too much, 400 Wt will be enough for
2nd configuration and 350Wt for first.
