Power Supply Minimum Requirements

[mrbigsexy]

I am running an E6750 on an FP-IN9 Fatal1ty board with 2x 8800GT 256MB, 2x HDD, 1x CD, and 1x FDD.

I would like to buy a 680 Watt supply because as far as I can find they are the most economical at $30. Not very pretty though, but functional.

I don't care about how it sounds since I can't usually hear the hum of the fan over the rat-a-tat of my AK in Counter-Strike anyway.

If anyone knows a "rule of thumb" for figuring out your equipments power needs please let me know, I used to jus "buy whatever" which always worked, but I wanna do it right this time.

If it's under $100, you can safely assume it's crappy and not a true power rating. Even Antec's lower end stuff isn't made by them and is junk.

The first place to look when at CF is the sticky on supplies seen at http://www.computerforum.com/90118-useful-psu-case-guides.html There's a section for choosing the supply according to the card you are running seen as well there. http://www.computerforum.com/90110-power-recommendations-video-card.html

Don't expect a $30 680W unit to come close to powering that system. As SirKenin has said, such a unit won't be realistically rated.

The Coolermaster Real Power 750W is a great option, as long as you don't mind the rebate. Also see http://www.computerforum.com/90117-ceewi1-s-psu-recommendations.html

The only time you see any higher powered supplies for under $80 that are even worth bothering with is when there's a mail-in rebate going along wiith a vendor's special.

I think for the 2010 build here the OCZ model seen at http://www.newegg.com/Product/Product.aspx?Item=N82E16817341003 will work quite well since the price will be down by that time.

Or maybe the 750w Corsair model seen at http://www.newegg.com/Product/Product.aspx?Item=N82E16817139006 What do you think of that one ceewi1?

Ultimately I went with the one in the link below:

OCZ is a good make of supplies. But even ceewi1 would agree with me on preferring a GameXStream model over one from the StealthXStream line. The 700w model in use here would seem to be better suited for running an SLI setup there. That can be seen at http://accessories.us.dell.com/sna/...etail.aspx?c=us&l=en&s=dhs&cs=19&sku=A1263951

"Your Recommended Minimum Power Supply is

400​

Watts"

was seen for the build here with two optical drives and 3 HDS with the ATI HD 2600XT video card and two pci devices. I guess I'm 300w over what I needed with the OCZ GameXStream 700w supply. With a simple change to the NVidia 8800 series for a video card and adding a usb device it still shows 400w as the minimum.
