SolutionHi Biccy,
you are right!
Many accelerator cards use 100 to 300 watts of power, which is significantly greater than the 75 watts of power that is supported through the PCIe x16 connector. Fortunately, the PCIe specification defines a method for supplying additional power to cards using auxiliary power connectors on the system motherboard that connect to the accelerator cards using special cables.
Depending on their physical configuration, these cables are capable of supplying an additional 75 watts to 225 watts of power to a PCIe card. HP Product Engineering has specifically added these power connectors to ProLiant systems to support these accelerator cards.
494323-B21 : option kit Includes the power cable required to provide addition power to this card via auxiliary power connectors on the system board

Hope this helps,
thanks

Re: DL380G7 and 150W graphics card support
Why do you need a highend video adapter. If this is a CAD or Photoshop box, I would consider building a highend standalone workstation for your application. I never use a file server for a graphical server. They are not designed for this task. My CAD/Photoshop workstation at home is a Supermicro server board, pair of E5430 Xeons (quad core 2.66), PC Power and Cooling 1000W customed wired power supply on a 20A circuit and 4850 graphics card.

Re: DL380G7 and 150W graphics card support
Aftab - I see this is for the DL380G6 - are you sure the cable supplied would fit the DL380G7? You know what HP are like for changing things!!
Michael - this application is for a broadcast-quality video server where the GPU is used for 3D-rendering of effects. I use a professional SDI video card to connect into the broadcast infrastructure. All of the frame rendering and audio manipulation (we support Dolby etc) is done on CPU !!!

Re: DL380G7 and 150W graphics card support
Hi Biccy,
As long as the part no 494323-B21 listed understand supported riser kit option in dl380 G7 quickspecs, there shouldn't be any problem
HP DL38X (1) x16 PCI-E riser kit 494323-B21
https://internal.support.hpe.com/hpesc/public/docDisplay?docLocale=en_US&docId=c04199811
its a same riser kit used in both the servers.
I had similar issue on previous generation of dl380 server and had hard time getting the cable. later on I realised that the cable comes along with the kit which I threw away assuming an empty box.
Thanks again.
Aftab

Re: DL380G7 and 150W graphics card support
I build CAD and Photoshop workstations for production environments. They are usually highend workstations not HP file servers. I don't think a riser would support a highend graphics adapter at 150W. I am not sure if the HP power supplies would give you 30A @ 12V for a power supply. Higher end adapters need 26A-30A @ 12V.

Re: DL380G7 and 150W graphics card support
Its a bit of a minefield as I am using ISS server hardware as workstations effectively. I've looked at SuperMicro but their 'full length' slots tend to be smaller than true PCI full length and so our cards dont fit. also didnt like the build quality on some of the servers I tried.
I did start of the product running on xw9400 with rack mounts...

Re: DL380G7 and 150W graphics card support
If the riser supports the 150W standard, it should work as long as the power supply can supply 26A @ 12V standard. The video cards use a standard molex for the additional power. The issue might be getting the connector from the power supply. Most highend video cards require 300W+, 30A @ 12V for the power supply. You will want to verify that you have a 12V rail on tha 750W power supply that can handle 26A-30A. Does your server have the additional molex available. If you need an extension, make sure you get a 16 gauge cable. Don't go with 18 gauge or smaller extension. You would not want to use any other slots on that riser. 150W is for all three slots.
I would be hestitant to use a HP file server for this solution. You can easily damage a video adapter with power problems or cause BSOD or other issues.

Re: DL380G7 and 150W graphics card support
I also use the DL370G6 with NVIDIA Quadro FX5800 cards and this has two cables going to it. Luckily this model serve comes with 750W PSUs and cables to go from the main loom to the card.
The DL380G7 has 750W PSUs as option but I was going to try my luck with 450W first - do you think this is pushing it as I will have 8-off SAS drives, two X5650 CPU and 12GB RAM....
