How much juice? 9600 pro

[Ruckas]

I was wondering if someone could break down how much juice a card needs? Like if the core is 400 and the ram is 600 (mhz) then ofcourse you have the fan... How do you tell if your power supply is sufficient?

That said, if I was to put a card in that takes 220 watts of power. And my CD-RW drive takes 10watts, then my DVD-ROM drive takes 5watts, Harddrive takes 20watts plus all the other parts.. My point, if it went over 330watts I would have problems right? In theory... Like if it ran okay with just my HD running, but when I stick a DVD in and that puts it over 330... Would that cause the computer to crash?

Think I just made something simple very complex Somebody straighten this out for me

Ruckas-

I'm running my rig xp 2500 = @ 2166 with 1 hd (WD caviar) 3 case fans, dvd drive, cdrw drive, tv tuner card, modem and my 9600 pro oc to 500/ 351 on a 300w psu and have never had any problems.

You're fine. Your PSU might not last as long as compared to a top quality brand though.

I have gigabyte 865pe + dvd + seagate80gb + p4 2.4 + audigy + 9600pro with 4 fans in a microatx case (lianli pc 9300) with a 200watt psu. If I add another hard drive I get PSU problems with the machine crashing.

If you constantly run your psu near it's peak, you'll probably shorten it's life and cause some stability problems. And, many generic power supplies have the peak wattage misrepresented--one may say 330w but can only deliver 200w.

How do you measure what's using what? Like, how much power does a average HD take? How much power does an average mother board take? Etc etc.... In comparison to my 330watt power supply...

But I gather that if I stick a 9600 pro in, I should have no difficulty. Least with power...

Thanks...Ruckas-

I read somewhere that a 9600pro only uses about 22watts.

Watts are volts X amps. Voltage will be constant at around 120 here in the U.S., so your 300W PS will put out 2.5A of current. Most manufacturers will list current draw for their products, though this information may be difficult to find. You can look it up if you are interested.

Anyway, a decent PS (in size and quality) won't have any problems with a case full of normal components, in my experience.

Here is a link to a site which lists typical component wattage requirements:

Not quite. The input on a psu is 120 volts ac, but the components in a computer run on lower dc voltages. So the psu converts the 120 ac to the different dc voltages required--3.3v, 5v, 12v. The amount of current a psu supplies to each of these rails differs on each power supply. Check with the manufacturer to see what they rate each at.

The power supplied is irrelevant, here in GB we run on 240 volts so in that theory our power supplies are twice as powerfull.
