YEs, you should be fine.
Just in the process of buying all my components and I just want to be sure that I've done my sums right with regard to choosing my power supply. I've searched and can't find anyone using this combination of power supply and mobo...
I will be running:
VIA CN-13000 motherboard (0.8 A on 3.3v, 3.8A on 5v, .09 on 5vSTBY and 0.31A on 12v, on full load)
Samsung Spinpoint M60 120GB HD (max 4.5W on 5v, which is 0.9A, right?)
512MB ddr2 ram
Creative Audigy SE soundcard (about 10W (from the 5v rail I assume) = 2A)
I'm intending to power my monitor (8" LinITX) off it's own power supply so I'm not taking that into account.
The OPUS 120w power supply will supply the following currents...
3.3v rail: 8A
5v rail: 8A
5v standby: 1.5A
+12v rail: 3.5A
-12v rail: 0.5A
So, according to my sums, I recon that I should have a maximum consumption of:
0.8A on 3.3v
6.7A on 5.0v
0.9A on 5.0vSTBY
0.31A on 12v
which should leave plenty of headroom, right?
Have I done my sums correctly and is my understanding of the electronics correct?
Thanks for your time
thanks, this is a great forum. can't wait to finish my project and post it for review!
A rail is a power rail. It's an output from a computer power supply at a specific voltage required by the PC.
An ATX power supply outputs three or four rails... One or two rails output 12v (in the case of a PSU w/ two 12v rails, one is dedicated to the CPU/motherboard and the other for peripherals), one 3.3v and one 5v.
It's less of a physical thing and more of a concept.
Sweet... Thanks for the reply. Just about to order all my stuff... The wait will be torturous!!!
