What are the power requirements to run 14 hard drives 910 are green drives and the rest are 7200rpm)on a low powered LE 1640 system with no cd drive and using built-in video 6150 chipset. I have a old Corsair HX 620 that I was planning on using.
 
Hard drives can use up to 2A @ 12V when they spin up. Check if the 620HX can handle 28A (+ ~3 A for the CPU) on 12V rails. Thats close to 375W on the 12V rails alone, should be listed on the sticker whether it can do it. Note that you may be limited on how the PSU splits up the rails, it may take 1 rail for the CPU only and only let you use the 2nd rail for HDD, which would severely limit you.

The Corsair 620HX is a single rail PSU with 50A on the +12V rail. So it should be able to handle 31A on the +12V rail just fine.
