[IMAGE] Aurora CPU (left) | Area-51 R2 CPU/GPU (right) Aurora models (R5 & newer) share the same PSU (&/or PSU pinout = can share cables) with Area-51 models (R2 & newer), where the 850watt Bronze/Gold, 1000w & 1500w PSU all have the same front panel layout & same front panel pinout, making both the PSU chassis & PSU case cables all interchangeable (however we might question if the 1500w should/could/would fit the Aurora due to its length) My reaction to the 6-wire 6pin Aurora CPU cable is that Dellware 'cost-cut' the cable in an effort not to pay for heatshrink, more zipties, & of course the 2 wires, 4 PSU female terminals & extra red 6pin connector; sad but maybe true that 5950x / 10900k can't get x8 wires to power those with Possible remedies below: 1) If you can find 51 R2 J8JFX CPU/GPU cable (google/eBay/call-chat w/Dell Spare Parts), u can use it 2) You can buy some yellow/black 18awg wire, buy some female PSU terminals & a 6pin (red) connector & add the extra 2 wires yourself (ie take the original cable apart, insert wires/terminals, put cable back together etc) (see ***Note) 3) Contact a custom cable maker ('sleevers'), send them yours, have them make it into an 8pin 3A) Contact custom cable-maker / sleever, who can make an 8-wire 8pin (4+4 etc) that has x2 6pin modular connex made from scratch (see pinout below) 4) Buy a basic CPU 8pin cable from someone, buy a pair of empty 6pin connectors > remove the unwanted 8pin it will come with (in otherwords, back all of the terminals out of the 8pin PSU end of cable & transfer on your 6pins which will plug into PSU panel red ports) ie create your own compatible CPU cable. Whether u source an all-black cable or a black-yellow is up to u ***Note: typical aftermarket CPU cables range in length from 24" - 26" - 29.5" … if the Aurora CPU cable is shorter than 24", you might need an 8pin CPU / EPS extension for it (I don't have the cable length for J8JFX, but it should be 24"+ from what I remember) Also note I can not get into cable making tips / advice, I don't have the time. However, in 15minutes or so, someone could add the needed 2 wires & extra red 6pin connector so it's a proper CPU cable  Pinout is below [IMAGE]  
So I have been looking at my motherboard, to determine if in the future I can move over the power supply to a different case and motherboard. Now I noticed the 8 pin EPS connector that provide extra power to the board, only has 6 wires connected to it. It's connected to an 8 pin socket, but only 3 x 12 Volt is supplied. 3 yellow, 3 black. Should be 4 yellow, 4 black. Pretty disappointed, looks like I will have to purchase a 1000 Watt PSU because the included power cables to the modular power supply are not populated to the ATX 2.0 standard, but instead to a DELL OEM sub standard.
