Aurora R7, replace power supply
The power supply in our Aurora R7 needs to be replaced (pressing the self-test button produces no results).
I've seen other posts and articles on this, but I haven't seen a clear post on what is the PSU is a compatible replacement.
So, what is a direct replacement (or improvement) PSU of our computer. I included a picture of the sticker on the existing PSU below.

The Aurora R7 PSU is standard ATX format which is 150mm wide, 86mm tall, and the length will vary. You should consider a fully modular PSU between 140mm and 150mm long . . . any longer will eat into your cable management space. This is a list of PSUs that meet the aforementioned criteria between 850 watts and 1000 watts pcpartpicker

The Dell/Alienware OEM 850-watt would pop right in. DPN is N1WJD (made by Delta). It's "modular" so be sure to get all the matching modular-cables.
If after-market, I would go with something like a mid-to-high-end 750-850w Corsair.
Whatever one you pick needs to not only fit, but also have TWO EPS Power-Cables (one for CPU and one for GPU-Power socket on motherboard). These are in addition to the others like MB-Main-Power and the PCIe-Power Cables (that go directly to the side of the video-card).
