Do you think I have enough juice?

Hi,

I recently upgraded my freenas server, and added a few hard disks and swapped the PSU and a few other parts.

Heres what it's running:

C2D E6420 (2.13GHz 4MB L2)
2GB 2x1GB DDR2
MSI P35 Neo2 FR (P35 Platinum)
2x Samsung HD753LJ (7200RPM)
2x Samsung HD103SJ (7200RPM)
Samsung IDE DVDRW
PSU: http://www.newegg.com/Product/Produc...82E16817151077
VGA: http://www.newegg.com/Product/Produc...82E16814127458
Freenas on 1GB USB stick
Multiple fans

My question is, do you think that the PSU is sufficient for the system? What if I add two more 7200RPM 103SJ's and a SATA card in the future? What about another two for a total of eight 7200RPM disks?

Mind that the OS overhead is very low. The server is configured for two Software RAID1 mirrors.

IMO, you're marginal with that PSU.

Using this:

and adding 4 80mm LED fans, 3 120mm LED fans, (you only say "multiple fans," so I went with MANY) it says your system needs about 292 watts.

You don't say how old the PSU is...and they do lose efficiency as they age...

IMO, you need a GOOD 400-450 watt unit.
