Sparks and fire after surge

Recently went to you guys for advice on how to best approach my second GPU getting ruined, and I think it helped. But here I am again after a few weeks.

Recap:

Act 1 - GPU1 started “surging” while playing games; narrowed this down to a memory issue—big games loading in their initial assets upon boot caused surge. RMAd the card.

Act 2 - GPU2 hooked up. Almost immediately upon launching a game is fried and did not POST. PC worked fine without the GPU. Some suggestions told me my Supernova G1 was a potential problem. I guess an especially shitty PSU that’s dying can fry a GPU. A few days after I swapped to using the PC without a GPU, my Supernova dies completely. I replaced it with an RM650i, and RMAd GPU2.

Act 3 - GPU3 hooked up, new PSU put in—all the cables and whatnot are the fresh new ones. I buy Destiny 2 and AC Origins after initial trial runs of games give no issue. I play about 15-20 hours of these two new games over the course of three days without problem. Life is great. On day 3, my PC hard-powers down while playing Origins. My heart sinks. The MOBO isn’t getting power (green light isn’t lit). I figure: maybe I tripped something weird, so I cut power to the PSU and power it back on. Green light. Start it up. All lights in the case begin to flicker and struggle, then sparks, and finally a quarter-second later there’s a small fireball in my case. I immediately cut power to the PSU and it’s gone. I took a chance and tried turning on the PC without the GPU hooked up and it seems to turn on fine, but I’ve kept it powered down since.

I plan to stop by a much more savvy friend’s place for a complete rebuild to see if everything’s in the right place. For the record, there’s very little in the way of visible damage anywhere.

Here’s the small discolouring I could spot: https://imgur.com/a/VD4VB

You can see it mostly in the top left corner. I can’t see anything noticeable on the MOBO. I’m just looking for suggestions on what could have caused the fire. For reference again, this is a brand new GPU, PSU and set of PSU cables. The only thing “old” in the chain is the MOBO. Is there anything we should look for or do?

Thanks guys!
