Ok guys here is the deal:

I have a dinky PSU that can put out 12V @ 2.5Amax and 5V @ 5.5Amax. I want to be able to drive (2) Seagate 15K SCSI drives off of this powersuppy. I have already looked up the power requirements for these drives and the idle power consumption is only about 0.5 - 0.8 Amps on the 12V line per device.

The PROBLEM is that each drive requires 1.8 - 1.5 Amps at startup/spinup. I will be using the Staggared spinup option BUT as you can see, I will be exceeding the max amperage that the PSU can handle at one time.

The 5V rail is not a problem because both drives spinning up at the same time only draw 0.8 Amps each and only 0.5 at idle.

WHAT I want to do is create some sort of buffer for the 12V rail so that durring spinup I am not overloading the PSU. Is it possible to create a series of large capacitors to create an electrical "buffer" of sort so that the PSU will not be overloaded as much?

Comments? Suggestions? Theories?

Thanks
