UPGRADE to 1000watt PSU from 850watt (or less) Aurora R5-R10 Area-51 R2-R7

Question

In light of nVidia RTX 3080 / 3090 video cards & their supposed high-power requirements / 'power-spikes', it's yet to be decided if the older 850watt model PSU 'is enough' for this generation of cards or the next gen, & if not then perhaps an upgrade to the 1000watt model may be the ticket … maybe yes maybe no ...

Regardless, based on recent eBay seller photos (see below) of the 1000w model, I've inspected the case cables / wiring / pinout for Aurora 1000w Gold PSU (Part# DP/N 0WTGN / 00WTGN made by Delta) (the 'same' 1000w PSU but made by ShenZhen HuntKey will have a different part#, for now that part# is unknown) & I've determined the front panel pinout for this newer 1000w is identical to both the 850watt found in Aurora R5-R10, & identical to the older 850watt + 1500watt found in Area-51 R2-R7

The conclusion is that an Aurora 850watt (Bronze / Gold) owner can make a subtle upgrade to the 1000watt, while an Area-51 owner can also 'upgrade' without making the jump to pricier 1500watt

What that means is the case cables you now have are compatible: simply unplug & remove old 850, install new 1000 & plug it all back up

Owners of the non-modular (fixed cables) 460watt / 550watt can do this upgrade but you need to buy the PSU chassis WITH the cables, with the full cable set

Below, compare side label specs:

850watt rating: 12VA = 32Amp | 12VB = 48Amp | 12V MAX = 792watts

1000w rating: 12VA = 42Amp | 12VB = 52Amp | 12Volt MAX = 912watts

*That's +10Amps on the CPU 8pin rail, +4Amps on the GPU rail, +120watts 12Volt Max

*The extra 10Amps (120watts) on 12VA was for more power to Intel CPUs like 9900k 10900k

*Whether that extra 4Amps (48watts) on the GPU rail (relative to the 850w) helps or not for 3080 / 3090 is unknown

There may be reasons to try the 1000w over the 850w (maybe your 850 no longer works & you need to replace it), it isn't for me to decide. What I can say is they share the same front panel pinout, which is to say the 850 / 1000 / 1500 models are all electrically compatible 7 therefore interchangeable, which is the true reason for this post

@Cass-Ole Good work, thanks.

Aurora 1000w Gold PSU (Part# DP/N 0WTGN / 00WTGN made by Delta)

1000w rating: 12VA = 42Amp | 12VB = 52Amp | 12Volt MAX = 912watts

Do we know how these two 12-volt rails are divided between R1-R6 (for PCIe graphics-card power)?

and

Are R7-R9 all of equal volts and amps capability (for CPU and GPU-Power connectors)?

Cass-Ole · Answer

*RED R7-R9 = 12VA 42Amp | BLACK R1-R6 = 12VB 52Amp | A = Motherboard, B = Video Cards

*My guess is that rail 12VA services connectors R7 R8 R9 (Red CPU/MB) & the 12volt pins in connector R13 which go to the 24pin connector … that 10Amp / 120watt increase over the 850w was for hungry new Intel CPUs … they also service the PCIE_PWR connector (75watts to the video card PCI-E slots)

*I assume rail 12VB feeds all 6 of the black PCI-E GRFX Video connectors (R1-R6), that 4Amp increase over the 850w may have been a then-current (& future-proof) bump against hungry AMD/nVidia cards

*12VD would be the White R10-R12 SATA/Molex

*The 1500watt has a pair of 48Amp video rails that each probably feed a 3-connector bank like R1-R3 & R4-R6 (or perhaps R1 R3 R5 & R2 R4 R6) … all of the above are guesses, I never got inside one & tested rails

Above, a sketch I made when I owned the Delta 1500watt (800GY) & 850watt Bronze (N1WJD), the wire colors represent the Area-51 R2 case harness, while 'newer' A51 R3-R7 wire colors may differ slightly. Aurora may/will have a few wire colors different from my sketch above

Below, typical wire colors

Regardless of case cables & wire colors, the 850 1000 & 1500watt PSUs are all electrically the same & so can work across all A51 R2-R7 + Aurora R5-R11

Not sure if this is on this topic, But I saw the photo of the 1000 watt power supply , and I was wondering if that can power up a riser or I can use a corsair or evga cable and make an extention on this to power up an addtional gpu ( Iam aware there are already (2) 8 pins available near the power unit ). thanks

My Computer: Aurora R6.

Today i had a technician on the phone from Dell Alienware. I asked if it is possible to upgrade the PSU from 850 W to 1000 W. He strongly negotiated this because that config isn't tested and could cause failures and problems or damage the computer.

If you have concerns about the pinout on the back of the OEM 850 and 1000W being the same you could always just buy an aftermarket 1000W PSU, or buy an OEM 1000w with the wire harness, or DR power or otherwise test the 1000w with your 850w harness.

So you think the Pinout is exactly the same on the 850 W and 1000 W PSU?

redxps630 · Answer

Based on Cass original post, OEM pinout are identical for 850 n 1k.
If this is single 12V rail or same number of rails, it probably means 1k psu supplies a greater max current than 850 on the same 12V rail(s).

After a lot of research I got myself the EVGA Supernova 1000 G6 (aftermarket) . It is working perfect in my Aurora R6.
