PSU 24 pin melted

[Duinchlfc]

Hi there guys,i hope this question is specific enough.My 750 watt psu 24 pin,of which 2 pins plastic literally melted off and some bits got stuck in the mobos 24 pin slot.Best effort was made to dig out the melted plastic out of the mobo and now a different psu is used for the mobo that had the melted plastic.

Now would whatever caused the 24pin to melt in the first place damage the board? I used to be able to mine with 4 cards but now max of only 2.Anything more would cause hang ups and crashes.

Did power distribution to the board get affected somehow?

Mining with 4amd card with 750watt??
u use seasonic pus?if so contact corbell of this issue,
It cable has melting issue

You never use auxiliary power for your mother board?

PSU up lorry.

Up lorry after only 4years?so much for cosair 7 year warranty.

You should probably note 7 year warranty means you can still get it swapped/ repaired FOC for 7 years, NOT that the product is guaranted to work flawlessly for 7 years. Otherwise you will be very disappointed at all forms of warranty.

State what cards you're mining on and motherboard, also if you're using any aux power for your pcie lanes. 24 pin melt doesnt mean PSU up lorry, but too much current is being drawn through the mobo.

Notice how people with 4x CF 7970 also dont have problems with 24 pin melting, because ATX PSU's and the relevant connectors werent exactly designed for max loading 24/7. Yes they can output their stated max power 24/7, just not the way you're using it. Although there's a getaround trick which is using aux power direct from PSU to PCIe lane which you didnt employ, so its user fault really.

Sorry but how can u manage to draw so much power from the 24 PIN, i mean whoever design it did their calculation right?

Okay this is where the technical stuff where i can a little lost in.As in Aux power for pcie lane,what does this mean? Does it mean i needed to use power pcie risers instead of normal ones? and i was using 4 7850s and a gigabyte GA-Z77X-UD3H board previously running off on a cosair hx 750w silver psu

Of course they did their calculations, but whether they did their calculation more than 4 years ago (before mining was cool) and managed to take into account that someone would draw the normal load + 225W (75x3), or basically a third of the max rating from a 4 year old PSU, through the 24-pin connector is another story altogether.

The 4 pin on motherboard to supply even more power to assist 24 pin.

My Corsair HX620W exploded in less than 24 months usage though warranty is 5 years.

I had the 24pin as well as the 4 pin on.Including the pcie cables direct to the cards so i'm wondering even with all that,too much power was drawn and melted the 2 pins of the 24pins?

can someone advise me what this means?

 

[wtfh4x]

Means you should buy a riser with a Molex input so the power that is usually provided by the board will come straight from the PSU to the riser instead of through the board to the riser. So you won't burn out the power connector that way see? Because instead of pulling 300W through the 24pin, it will draw 75W through each separate molex.
