Will my PSU be powerful enough?

Hi

Could an expert tell me if my psu will be able to handle this spec please.

Pentium D 3.2ghz dual core
6gb ddr2 800
8800gtx
2 x sata hard drives
6 x 15000rpm hard drives
Scsi pci-e raid controller
scsi pci host controller
2 x dvdrw drives
Card reader
usb pci card
4 120mm fans

thermaltake toughpower 850w psu

I think thats it for now.. this was a bunch of random equipment i have picked up along the way so decided i would combine it together to make a decent server for streaming. going to add it all in soon so thought as its alot of hardware i might be doing the psu alot of harm, so thought to ask about in case i need to buy a second psu.

Thanks

 

That PC will use roughly 400-420W at full load. An 850W PSU is frankly overkill.

 

Excellent! Thanks

 

Maybe a corsair 850 is overkill...but that thermaltake will probably struggle to make half the rated wattage.

 

No Killerbug, the Thermaltake Toughpower is a CWT unit underneath, the exact same as the Corsair TX.
