do I need a new power supply

Guys as of right now I have 7 hard drives installed in our file server I will be adding 4 more for a total of 11. Right now I'm running an Antec Earthwatts 380 watt power supply btw the cpu that's installed is a core2duo 1.86 and I have no optical drives installed. So my question is do you all think I can pull 4 more drives on this 380 or is it time to upgrade the power supply?

You would be pushing the power supply, depending on how old it is. I would upgrade to at least a 550W unit of quality just to be sure.

I have the same configuration for my current file server (same PSU). E6300 + 6 HDDs (1 Raptor for the OS) and my UPS is telling me there's a 96w load. If the PSU isn't that old, it shouldn't have any problems with 4 additional drives (if you don't have an add-on GPU).

The only thing that may be an issue is peak current during spin-up at boot. If you're using a hardware RAID controller and there's an option for staggered spin-up on the controller or drives, I'd use it.

If it's an option (probably the easiest: Windows on an admin account), consider undervolting the CPU. In my experience, Intel set the default voltage on those Core 2 chips to way higher than what most of them need to run stably. I messed with a C2D E4500 in my work PC, which I believe defaulted to 1.325v. I got it down to 1.1875v (lowest I could select in software). 1w drop at idle, 7.4w at moderate load (Folding@Home), 15w at extreme load (Linpack), not to mention lower temperatures.

Thanks for the info the system currently runs a perc5i raid controller but this box will be a dedicated freenas system so that raid controller will be replace with an IBM M1015. Also I'm running the below video card it did not come with on board video.

In that case, you may need to upgrade the PSU. Something around 500w with a single rail would be ideal.
