It is pretty accurate ... however what it does not do is factor in load
to the equation. Take the end figure it gives you and add 10% is my
best guesstimate on correct power supply requirements.

Having just looked at it in more detail, the other *crucial* thing it
doesn't take into account is the increased power consumption when
overclocking. For example, although the Athlon XP is supposed to draw
around 60~70w, it can easily go over 100w if you overclock it a little.
Start to put 1.85v and 2200MHz+ through it and you'll soon be over 100w.
Similarly GF6800's. A GT may be "only" 105w, but not when its run a 1.4v
bios patch and 440MHz! Its probably nearer 130~140w then.

Well thats a very misleading way of saying it! "Load" normally refers to
when a component is working hard, i.e. as opposed to "idle".

What I mean is the increase - over and above normal "load" - caused by
overclocking.

Chip.

Are some of those numbers a bit high? I just read an article that talked
about the 6800 cards using about 35 watts less than that page shows (i.e.
the low 70's for the Ultra instead of 110.)

Thanks,

Larry

@ndrew

But you should also consider that you'll never be using EVERY component at
its peak load at once. For example, you'd never use a CD, DVD, floppy, and
all USB and firewire devices all at the same time.

Thats *precisely* my point. Where in that definition does it mention
*overclocking*?

Everyone understands what "load" means in the context of computers. My
point is that the heat output increases significantly irrespective of the
load, when you overclock.

When you say "That's what I meant by load", I really don't think the word
load expains that at all!

Anyway, none of this matters. Lets not fall out over it.

Cheers

Larry

Good point. But on the other hand, the CD, floppy etc are all small fry in
the overall scheme of things. The real issue is if your graphics card
starts pulling 120w and your CPU starts pulling 100w (both of which are not
unreasonable) and your disks are pulling another 50w (say). 270w all at the
same time all off the 12v rail. Its not a cakewalk!

Chip

Ok everyone I bought a 480W Antec PSU and a surge protector and the
problem has stopped. NO MORE ARTIFACTING!!! It might just be me but it
seems as if the components of my machine are running a lot better with
the new PSU. Thanks for all the feedback & help!!

--Brenden

A good idea, except that it may not reveal the problem. A P4 at 3 GHz might
easily be consuming 70w and the GF6800 overclocked could take up to perhaps
120w. At 12v that's 16A, without anything else plugged in! So it might
fail even with everything else disconnected.

Chip

Ahhh,.... a good might PSU or will fix most of the problem.
