Want to build it my self. Have picked out parts but not sure on the power supply. Not a gamer, more internet, Office type stuff, multi media, kid games for my 11yr old daughter. Cost so far is $833 @ Tiger Direct.

Here is a list of the goods:

MSI 975X Platinum Intel Socket 775 ATX Motherboard / Audio / PCI Express / Gigabit LAN / S/PDIF / USB 2.0 & Firewire / Serial ATA / RAID

Intel Core 2 Duo E6300 1.86GHz / 2MB Cache / 1066MHz FSB / Dual-Core / OEM / Socket 775 / Processor

ThermalTake Jungle 512 / Socket 775 / Intel Prescott / Copper Core / CPU Cooling Fan

Crucial Ballistix Dual Channel 1024MB PC6400 DDR2 800MHz EPP Memory

Seagate / Barracuda 7200.9 / 160GB / 7200 / 8MB / SATA-300 / OEM /
Hard Drive

DiabloTek Radeon X700 Super / 512MB DDR2 / PCI Express / DVI / VGA / TV-Out / Video Card

Sony DRU830A / 18x DVD±R Burn / 16x DVD±R Read / 8x DVD+RW / 6x DVD-RW / 8x DVD±R DL / 12x DVD-RAM

Power Up Black ATX Mid-Tower Case with Front USB and Audio Ports and Touch-Sensitive Controls w/ 1 - 120mm front and 2 - 80mm rear fans

The video card recomends 350w ps but do I need one with plugins for the 3 fans as well? I saw some with the 120mm but nothing about the 80mm's.

From what I have read here you people know your stuff, so any advice would be helpfull.

well, i recommend fsp stuff, other people will recommend other stuff. for what you've got there though, i dont think you need anything too hefty. 600 watts will more then do fine. i say 600 because generally speaking, 500 watt psu's dont have enough amps on the 12V rails.

this one is 550 watts

that psu 101 link above is an excellent resource. check it out.

First, you can get Y-splitters for more fan connections.. just depends on if your fans are 3 or 4 pin connectors.. fans don't use much power so don't let that be a factor into your power supply choice.

You're going to hear quite a bit of talk about power supplies.. if you're not overclocking the machine, you won't need more than 400W. See for yourself:

Also, you should probably consider going with 2x512MB memory instead of one 1GB stick.. dual-channel mode is nice, and your motherboard has two more slots if you want an upgrade later.

silencer - not interested in overclocking and the memory is 2 sticks. I reasearched the dual channel memory. Thanks for the calculator link. It say's I need a min of 200w.

pottymonster - thanks for your input. Will keep an eye on amps thur the rails.

Everett - excellent link, to much info for this early in the am, will read thru after work.

Thanks to all who replied. I reasearched all other parts but did not realize psu was such an important piece of the pie.

Thanks again...
