Is there an app or site that will calculate the wattage you need?I

[TivoOwner]

It would be nice if you could come across a app or site that would allow you to enter your components and recommend the power supply you should buy. If Dell every comes through on my 8800GT order I'll have:

(2) 8800GT
Q6600
EVGA 680i Mainboard
(2) 2GB G.Skill DDR800
SB X-Fi Xtreme Gamer
160GB Raptor SATA
300GB Seagate SATA
IDE DVD Drive
Plus several fans of course

If I overclock the Q6600 and 8800GT's I'll be drawing even more.

Is this a place that will compute this for me? TIA

I'm thinking my Ultra-X 600W (FAR) won't be enough.

not a really relauble site@!@!
There are all kinds of sites but none are very accurate@!

Depending on your o/c for the cpu & gpu's your rig could pull around 400-450W under full torture load (gaming, HDD copy, DVD rip, cpu burn). Assuming that you're referring to the Ultra X-Finity, while it's not the best choice it should work fine.

QFT. The majority of them greatly exaggerates the real power draw.

Also, power draw has nothing to do with whether a particular PSU which meets that power draw on the label can in reality meet it in actual usage.

600W is overkill for ANY computer that exists today. Don't worry about it.

That is a very obtuse statement.

Letsee...

Heavily overclocked quad
HD2900XT crossfire overclocked
crapload of HDs and opticals

could overdo it on a 600W Ultra-X

Yes, their is an site that will allow you to do this but is always off by several watts(I don't mean like 4 or 5 either, were talking greater than 50W).

Really?. That machine didn't not like being run on a 600w PSU... Not everyone has the same computer. Not to mention the fact that a computer will function fine if it is drawing 400w or 700w from a 1kw PSU. Does everyone need a 1kw PSU? No. But not everyone needs less than a 600w either.

EDIT: It is possible to go through and find out the power requirements on each rail for each part you will be putting into your computer; another option would be to find a place that has a listing of peoples' rigs, and try to find one close to what you will be building.

If you want accuracy and for actual brand and model recomendations that would cost allot of money to use. I can't see a free site like that ever poping up. The time it would take to stay on top of power requierments and the latest PSUs and what they are capapble of powering would be allot of man hours. Besides there are so many veriables in there that you would have a wide range of recomendations. Anywhere between 400W and 1000W would be a common recomendation and the list would be pages long.

Um, no.

Say, HDD = x watts
Raptor HDD = x+y watts
C2D = z watts
blah blah

I have Raptor and HDD and C2D; z + 2x+ y = watts pulled.

This is upper bound of course; IE you take the highest wattage drawn from the C2D series of chips and use that for all the guestimations. This is not a problem because overshoot can't hurt much. Then watts pulled + 150 = PSU wattage you should buy.

Harddrive and Optical drive tech is largely the same tech that was out 5 years ago. Graphics cards-- what site doesn't review power draw of the card????

What I'm trying to get at is

NO NAYSAYING.

Or rather, it wouldn't be that difficult.

For a single gpu system without anything bizarre, yes. For SLI systems, it's certainly possible to hit the wall at 600w. Also if you had something crazy like a 172w peltier + some other exotic things, that could conceivably cause issues for a single gpu system.

Let's make it "600W is overkill for ANY single gpu computer with standard configurations that exists today."
