Newbie needs help with connecting power Evga 1200 supernova P2 PSU to Supermicro X10SRA 2011-3 MB

Hi. The motherboard you are using is also used for workstation, high reliability computation, and server use, and supports extra features for that purpose.

I'm assuming you are using it for gaming or rendering/editing/3D modelling. In that situation, all you need is the 24 pin ATX and the 8 pin JPW1 and JPW 2. Yes you just smoosh the two halves together. They should sort of lock together.

None of the other power connectors are supported by your PSU directly, I think.

The PCIe 6 and PCIe 6+2 are for GPUs and the 6 part of the 6+2 is identical to the standard 6. The 6+2 allows for a lot more power to be delivered to the GPU (75W for 6, 150W for 6+2)

What are the rest of your components and what are you using the system for?

OK , just checking that the bits are sensible. What PSU, you need a decent one? The GTX 970 will drive a 4K display for editing. You would need a lot better if you wanted to game.

The cables are rated for the load and it keeps the number of cables running through the case down to a reasonable amount. Many GPUs that would use that PSU might need two 6+2 PCI-e connections, and it is much easier if they are both on the same cable. If one were to run 4 x Crossfire of weaker cards, eight PCI-e connections might be needed, so two per cable is about the only way to do it.

For the SATA, it again makes it convenient to power a couple of SSDs from a single cable, keeping the clutter in the case down. I use and recommend the EVGA 110-B2-0750-VR and find the cables to be convenient.


Microsoft DirectX is a collection of application programming interfaces (APIs) for handling tasks related to multimedia, especially game programming and video, on Microsoft platforms. Originally, the names of these APIs all began with Direct, such as Direct3D, DirectDraw, DirectMusic, DirectPlay, DirectSound, and so forth. The name DirectX was coined as shorthand term for all of these APIs (the X standing in for the particular API names) and soon became the name of the collection. When Microsoft later set out to develop a gaming console, the X was used as the basis of the name Xbox to indicate that the console was based on DirectX technology. The X initial has been carried forward in the naming of APIs designed for the Xbox such as XInput and the Cross-platform Audio Creation Tool (XACT), while the DirectX pattern has been continued for Windows APIs such as Direct2D and DirectWrite.

Direct3D (the 3D graphics API within DirectX) is widely used in the development of video games for Microsoft Windows, Sega Dreamcast, Microsoft Xbox, Microsoft Xbox 360, and Microsoft Xbox One. Direct3D is also used by other software applications for visualization and graphics tasks such as CAD/CAM engineering. As Direct3D is the most widely publicized component of DirectX, it is common to see the names "DirectX" and "Direct3D" used interchangeably.

The DirectX software development kit (SDK) consists of runtime libraries in redistributable binary form, along with accompanying documentation and headers for use in coding. Originally, the runtimes were only installed by games or explicitly by the user. Windows 95 did not launch with DirectX, but DirectX was included with Windows 95 OEM Service Release 2. Windows 98 and Windows NT 4.0 both shipped with DirectX, as has every version of Windows released since. The SDK is available as a free download. While the runtimes are proprietary, closed-source software, source code is provided for most of the SDK samples. Starting with the release of Windows 8 Developer Preview, DirectX SDK has been integrated into Windows SDK.

DirectX 11 came out with windows 7 11.1 with Windows 8 11.2 with Windows 8.1 and DX 12 is pert of Windows 10. Developers need to take advantage of its capabilities to the fullest extent, so we await DirectX 12 games and other applications.
