What kind of PSU do I need?

Here's my system setup. My power supply, motherboard, and 2 graphics cards failed a few months ago, and now that I've got everything replaced, I need to make sure the original power supply was adequate. I suspect that it wasn't and that when it failed, it took the other components with it. I tried using an online PSU calculator but there was too much stuff I didn't know the answer to. Here's my system set-up:

Case ( Tuniq 3 Gaming Tower Case)
Power Supply ( 850 Watt -- Thermaltake Toughpower W0172RU Power Supply Quad SLI Ready )
Processor ( Intel Core 2 Quad Processor Q6600 (4x 2.4GHz/8MB L2 Cache/1066FSB) )
Processor Cooling (iBUYPOWER Liquid CPU Cooling Fan System Kit --- [for INTEL CPU] )
Motherboard (Asus P5N-T Deluxe NVIDIA nForce 780i SLI Chipset w/7.1 Sound, Gb LAN, S-ATA Raid, USB 2.0, IEEE-1394, 3-Way PCI-E M )
Memory ( 4096MB [1024MB X4] DDR2-800 PC6400 Memory Module Corsair XMS2 Xtreme w/Heat Spreader )
Video Card ( 2x eVGA NVIDIA 260-216)
Hard Drive ( 320 GB HARD DRIVE [Serial-ATA-II, 3Gb, 7200 RPM, 16M Cache] )
2nd Hard Drive ( 160 GB HARD DRIVE [Serial-ATA-II, 3Gb, 7200 RPM, 8M Cache] )
CD/DVD Drive ( LG GGC-H20L BLU-RAY/HD-DVD Reader & DVD±R/±RW Burner Internal Combo Drive Black )
CD-RW/DVD-RW Drive ( Sony Dual Format/Double Layer 20X DVD±R/±RW + CD-R/RW Drive Beige )
Sound Card ( Creative Lab Sound Blaster X-Fi )
Network Card ( Onboard LAN Network (Gb or 10/100) )
Floppy Drive ( Mitsumi 1.44 MB Internal Floppy Drive Beige )
Operation System ( Microsoft Windows Vista Ultimate 32-Bit )

I used a power supply calc. on your rig and it seemed a bit low for what you have. I wouldn't trust it 100% but it said you were using 450w. I think your 850w psu was sufficient, but just crapped out on you.

850W is plenty for that system. The power supply was of good quality, perhaps it was just a dud? Can you get it replaced under warranty?
