I recently bought an Arima SW350 motherboard.

It supports 16 ddr simms as well as 2 opteron 2xx CPUs, so I imagine it may have pretty heavy power requirements...

It has a 24 pin ATX power connector, 2 4 pin "P4" power connectors, and an 8 pin EPS power connector.

My supermicro power supply has a 24 pin ATX connector and the EPS connector, and one P4 connector.

Can I safely run this thing with only one P4 connector plugged in? Can I safely get a "hard disk to P4" adapter and use that to power the other P4 connector on the motherboard? Do I just need a new power supply?

The board's documentation is pretty thin on the topic.

Side note - I think they're DIMMs and not SIMMs – MDMarra Jun 28 '10 at 16:38

I should have used the technical term "memory thingies" – chris Jun 28 '10 at 17:24
    
Of course they’re DIMMs; SIMMs were not DDR. – Synetech Mar 8 '11 at 18:59
