PSU Blew!

Sorry, but that's not drawing anywhere near 800watts at full load, regardless of cpu and any overclocks. Spend some cash on a Seasonic Power Angel, a Kill-a-Watt, or a UPS to see what your actual draw is from the wall, then multiply that figure (in watts) by about .78 to get an idea what your actual draw is to the psu from your components.

Some numbers for you: 7800GT SLI (and other configurations) Total System Power Consumption Comparison. Now let's add in 100watts to make up any difference five more hard drives, some extra fans, and a modestly overclocked cpu would pull... adding 100w across the board does not cause the 7800gt sli's to break 400w. Remember, those numbers they're showing you are TOTAL system power consumption measured with a Power Angel at the wall. I still suggest you find a way to measure your actual usage. It's always interesting to see what's really going on.

As a side note, I noticed that that comparison has a 6800ultra at ~215w. I happen to have a 6800U in a very similar system (x2 4200+, a8v dlx, 4x512MB, m-audio revo 7.1, seasonic s12-500, 1x74GB raptor, 1x300GB seagate 7200.8, evga 6800Ultra agp) and from my measurements from my APC RS800 it uses about 180w at absolute full-load (both cores at 100% and doom3 going with me running around killing stuff). What does this mean? It means the numbers they have there, at least for the 6800U, are plausible.

I can't seem to get to your System Rigs specs through your link in your sig, but i think I've made my case here. Unfortunately you've already spent the cash on a huge psu, but at least you'll know you have a severe amount of headroom with it, and won't go around telling people your system uses 800w 🙂 Enjoy the silencer.

Here's my system:

AMD X2 3800+ @2400
2 EVGA 7800 GT in SLI
2 sticks 1 gb each G.skill ddr mem
1 Seagate 7200.10 400gb HD
4 Maxline III 300gb SATA HDs
2 Seagate 7200.7 200gb PATA HDs
1 X-Fi sound card
1 SATA/PATA PCI Raid card
2 DVD burners
7 LED case fans
1 Diskette drive
1 Zippy USB KB
1 USB Kensington Trackball
1 Logitech Rumblepad II
1 Logitech Force Feedback joystick (Old model, first one Logitech made i believe)
1 USB external fan (to keep me nice a cool)
1 Espon 1280 USB printer
1 HP 7400C USB scanner
1 External USB HD
1 300gb e-Sata HD
1 Firewire always connected to either my ipod or another USB HD for transfering data from mac-pc or pc-mac
1 MS Sidwinder Josytick connected via old-school gameport-usb connector
1 USB Logitech webcam

I think this setup takes quite a bit of power, IMO.

Around 40A should do it. You neglected to mention the motherboard, and if the peripherals are externally powered (i.e. from the wall). I don't think your printer and scanner draw power from the USB port, eh?

The mobo is an Asrock 939SLI32-esataII.

smthmlk, I have a Cyberpower UPS (forget the model offhand). I'll see if the SW tells me how much power is being drawn and let ya know.

my first question, why two joysticks?

Well, I use the gamepad for driving, arcade and GTA type games. I use the Logitech FF joystick for driving and flying games (it has great FF) and I use the good old MS Sidewinder joystick for the twist axis for games like Mechwarrior where you can twist the body while still moving forward.
