Power Requirements?

[chez]

I am in the process of planning and building a NAS (Network Attached Storage) box.

I plan to run a basic linux distro and will have the following hardware -

Abit IC7-Max3 Mobo
1Gb RAM
4x 320Gb WD SATA HDDs
2x 200Gb WD SATA HDDs

What I am wondering is what power requirements this will have?

I have an Antec 300w PSU spare and wonder if this will suffice (as no overclocking will be done and the only processing will be for the RAID arrays..)?

Thanks in advance

HD's don't use a great deal of power, your 300W Antec PSU will be fine.

HD's don't use a great deal of power, your 300W Antec PSU will be fine.

However, they do at startup. On a 300W PSU you might want to use a staggered spin up as an HDU can consume about 30W at spin up (about 15W during normal use). 30Wx6 = 180W alone during boot, leaving aside the CPU and inefficiency of the PSU.

I'd check if your BIOS allows for this and if not, think about a beefier PSU.

Try it anyway but if it fails to start, you may have your reason - however be careful, if it loads too much it could blow the PSU, though it's not a Qtec so it should be fine and just shut off as Antec's are(/were? - they have fallen a lot) a quality brand.
