PCI-e 8 pin power from a P4304XXMUXX

My system is a P4304XXMUXX chassis with an S2600STB motherboard, 750W Intel PSU and a Xeon Gold 6148 (only 1 CPU so far)

I have a Gigabyte GeForce GTX 1070 in the 5+6 PCI-e socket position.

The GPU uses 150W, but according to the S2600STB specs it only provides 75W on the PCI-e socket, thus I need to supply power to the PCI-e 8 pin connector on the GPU.

Of course the 750W PSU is no where near the limit so I should be able to provide the 150W to the GPU with appropriate cables.

The options I guess I have are:

1) Does Intel sell cables for this? The power board in the chassis has 5 unused 4 pin sockets - does Intel sell a cable to connect from these to the PCI-e 8 pin connector on the GPU?

I can't seem to find the details of the P4304XXMUXX power board anywhere showing the limits of the sockets.

2) Should I use a standard double molex to PCI-e 8 cable I can get online and run that off the available molex connectors in the front of the chassis?

I'm not sure of the power available from these. I currently only have two 256GB Samsumg SSDs connected to the molex leads at the front of the chassis.

3) Should I just make a cable myself? (yes this would be easy enough if I could find the specs of the limits of the 5 sockets on the chassis power board)

Thanks for any help on this.

Hi, Canno,

 

 

In regard to your question how to connect the Gigabyte* GeForce GTX 1070 to the Intel® Server Chassis P4304XXMUXX.

 

 

Gigabyte recommends to use a PSU of 500W, additionally, the GPU requires extra power using the 2x4 power connector.

 

 

More details at https://www.gigabyte.com/Graphics-Card/GV-N1070G1-GAMING-8GD-rev-10# sp Gigabyte Specification

 

 

I suggest you get a 4 Pin Molex to 8 Pin ATX EPS12V Motherboard Power Supply Adapter Converter Cable or 8-pin PCIe to 2xMolex and use 1 or 2 of the spare Molex connectors of your system.

 

 

I suggest you get the spare cable from our Technology Providers. The link below http://locate.intel.com/ locate.intel.com shows you the providers available near your home.

 

 

I hope my answer solves your question.

 

 

Regards,

I'm having great trouble finding details and part numbers on the intel site for any extra cables for this chassis.

The first and most important would be the number for a cable that plugs into the chassis power board.

As I mentioned there's 5 empty sockets in the power board that are 2x2

Calling a provider results in them asking for part numbers that I don't know.

The power board itself has 2 numbers I've found - one on the board itself - DAOS6CTB4DO

and the other while googling that number - R4208P4MHGC

I can't find these numbers searching the intel site - I'd like to find some documentation on the specifications of the board.

Though I can find the board sold on amazon and ebay

The part itself looks like this: https://i.ebayimg.com/images/g/HMIAAOSwWnFV76nZ/s-l1600.jpg https://i.ebayimg.com/images/g/HMIAAOSwWnFV76nZ/s-l1600.jpg

As you can see, it has 5 sockets on the left that are 2x2 - they are all empty in my chassis.

Is there somewhere that lists the power board or the cables on intel? I can't find them using the intel site search.

Hi, Canno,

 

 

In regard to your question how to connect the Gigabyte* GeForce GTX 1070 to the Intel® Server Chassis P4304XXMUXX.

 

 

The available spare cables for the Intel® Server Chassis P4304XXMUXX do not match your requirements; however, the power board has standard 2x2 12v Molex connectors. It is possible to get them from any pc retailer.

 

 

I am sending you the http://download.intel.com/support/motherboards/server/s2600cw/sb/s2600cw_p4000g_configuration_guide_rev1_42.pdf Configuration guide and spare and accessories guide for the Intel® Server Chassis P4304XXMUXX

 

 

I have attached a possible example from Newegg.

I will gladly assist you if you have any other question.
