I am going to have a Blu-Ray Drive, (4) 3tb Hard drives and a SSD or 320 GB HD for my Boot Drive. My Case is the Silverstone GD06. What sort of power supply do I need to run all of that stuff? Like I said I have added one optical and one hard drive to my current office PC and just tapped into the Molex power supply so I am totally clueless about a build.
380-450 watt PSU will be plenty.
The average i3 2100 system with the CPU, RAM, 1 hard drive, 1 optical drive is going to draw about 100 watts at max use.
Add another 30-40 watts for a few more hard drives and you should have plenty of power.
This is a pretty good calculator that joeydrunk
sent me a few days ago. I would check your system at about 50% cpu utilization as it will likely run less than that.http://www.antec.outervision.com/PSUEngine
When I plugged everything in that you are using the calculator gave me a system use of about 175 watts.
