Close call - reminder to buy a quality psu and check/replace if old

[pewpew]

A moment of silence for my 7 year old XFX Pro850w

The cable leading to GPU melted itself and committed suicide (not sure why?) after a good 7 years of service. Created an awful smell... The whole house stunk of burned plastic you do not want to smell burned PSU

A reminder not to skimp on your power supply, my xfx failed and the included protection saved the rest of my rig. Also if you have an older Psu maybe it's time to check using a multimeter/replace the old girl.

photo before and after I got the pliers out, was truly plastic welded on there

It still shouldn't fail like that.

Tell me about it, I still can smell burnt psu in the office. It had been working with my 1080ti for some time in this config and I have made no recent changes so your guess is as good as mine.

Opted for a replacement psu with a 10 year warranty so shouldn't have to be worried about this again

That was a high quality psu and with psu's offering 7 and 10 year warranties these days it's not that old really. Just out of interest were you powering that 1080ti from the two pci-e leads that are daisy chained from a single lead at the psu? If so it could be the case that the gpu was drawing too much power down the one single cable. A 1080ti can easily pull over 300w, more when overclocked. It's always advisable to power these high end cards with two seperate pci-e leads from the psu.

There's decent chance of this eventually happening again, if you try to power 300W card through single cable.

Hmm i remember thinking about this years ago... then i saw this video by jayztwocents https://youtu.be/UL7KIVI_hJg?t=340 where he compares 1 pci-e cable (+daisy) vs 2 cables.
He comments that the power limit for 1 cable should be 396w

Spoiler: Found the thread!

which is well over the 330w limit of my GPU so i just stuck with the 1 cable and never thought about this again.

Just to be safe I will add another pci-e connector
