NetFPGA SUME power supply

Question

A customer on our website asked the following question:

Hi,
For our research project at USI Lugano (CH), we need to install a NetFPGA SUME board inside a server, which unfortunately does not provide any 6-pins/8-pins power connector.

Is there any power adapter, such as this one: 
http://store.digilentinc.com/60w-pcie-12v-5a-power-supply/
which is also compatible with NetFPGA SUME board?

Is there any other solution that allows to power the NetFPGA SUME, without relying on the server?

Thank you!

The response is below.

Hello,

Unfortunately, Digilent does not have a similar power supply that is compatible with the SUME. I looked around online for a similar supply in the "brick" form factor but wasn't able to come up with anything useful. 

If you want to power the SUME without relying on the server to provide the power, my personal (unofficial) recommendation would be to get a separate PSU (it'll come with the appropriate cabling) to power the SUME. If you are only powering the SUME off of the PSU, the PSU shouldn't need to be much more than 250W (to be on the safe side). You would need to short two of the pins on the power supply as per the power section of the SUME reference manual

I have asked some of our applications engineers to provide further input on this.

Thanks,
JColvin

Hello,

The  http://store.digilentinc.com/60w-pcie-12v-5a-power-supply/  is not recommended for the SUME. You need at least 75W and at the most 150W which this PCIe power supply does not give. I agree with JColvin that your best option then is to get a seperate PSU and follow the set up instructions at the link JColvin supplied.

thank you,

Jon
