Burned PCIe to PSU connector

[felixbrucker]

Hi,

i just noticed a failed card (280x) wasnt dead but rather the PCIe to PSU connector was burned and i wasnt able to pull it out, the plastic has molten with the socket it seems.

the PSU in question is a Enermax 1000W ECO, this PCIe Connector was attached solely to that 280x, my question is: how is this possible? the card doesnt draw that much power and the cables seemed thick enough to handle a 280x

Those r9 cards draws alot of wattage i wouldn't suggest using powered raisers with them unless it's a high quality one , by the way i have seen so many cases like yours and all are r9 3xx,2xx with molten sockets those gpus are power beasts

i have run my 290x off another enermax gold rated psu for over 3 years and it never broke/melted, seems to be psu build quality? or just cable quality?

If the socket is not well plugged in place, with this amps going to the gpu it could make some sparks and very high temp. Resulting in molten socket .....maybe

it was plugged in tightly

to be clear, im not talking about molex connector but 6/8 pin pcie, even my standard desktop should handle a 280x (8pin + 6pin) just fine, not sure what the problem was

[antantti]

It is possible if dual mining heavily, I have done it with 290. You need to use separate pcie cables or cable cooling if you are going to max it.

was the pcie cable used on a lot of different gear?

was it unplugged and replugged into different jacks.

pcie plugs have very short lifespans when plugged and unplugged.

a pcie cable should not be plugged and unplugged 30 times in its life span!!!

most pcie cables are rated between 10-20 plug an unplug cycles.  Seems silly that 15 times can ruin a cable but it is true.

that is something new to me. I have plugged PCIE cables many times when I have to adjust/test the rigs.

strange though that my other system survived just fine for 3 yrs, i wasnt dual mining as well

the connector which got burned got plugged in only once, the connector which didnt get burned (gpu side) was plugged in 2 times

Then it only leaves poor connection on psu side. Who is the first psu manufacturer to introduce mining series with heavy cabling + good connectors + cable temp sensors?  )

me too  first person that told me cycles are under 20.  I thought you are a ff'ing moron I did research found out I was the moron for doubting him.  the pcie cable side has a shorter life span then most people realize.

Same issue i had almost but with a junk coolmax 1000 watt PSU where the MB power connector was what melted ruining the MB as well, on the wires the PCI slots drew juice for the GPU's.
I learned my lesson the hard way and shelled out some BTC for a Corsair RM1000i, new MB and all powered risers.
Been running smooth since. Get you some decent powered riser and youll be fine.

[CoM1ner]

The R9 series are power hungry monsters.

What are reputable risers? I only knew of the chinese ones that are everywhere.

The ones i have are from newegg, the 12.95 ones sold by MintCell. Im not sure if they are chinese or not, but they havent had any issues
and keep my release day RX 480s powered well.

It has nothing to do with the amount of power the GPU uses because the 280x has usually 1x6 pin + 1x8pin connector, so 6 +12V wires.

This usually happens because the female end of the modular PSU keeps getting looser and looser everytime you plug it in and out. Either that or you had the wire hanging at an angle and it wasn't in horizontally but was tilted at an angle and caused a bad connection.

This is why I hate modular PSUs and usually love PSUs like the Corsair CX750 however most 1000Watt > PSUs are modular.

This is very common and if you search it happens to people with $500 Platinum PSUs who never mined in their life they were just gamers.

hmm, no angles at the psu side (where it broke), only at the gpu side

i also own a cx750, so far it has been working great

[Amph]

buy corsair or evga, i usually discard every other psu

[Searing]

not sure if this applies to what is broke...but here is an adapter trick for a knc titan cube (works well with a 16 awg split adapter)

for what it is worth...(I have 2 of these with this issue it works well)

Not sure if this applies to your problem ..but just in case it does...you won't have to replace the plug on teh board?

also sent a pm

anyway for what it is worth..may not apply to you..but hey no harm in posting the links below in case it can work

https://bitcointalk.org/index.php?topic=170332.msg13872248#msg13872248




Below is using common 16awg Y adapter....this is the KNC model came with the cube...just clean the plastic gunk off to bare pins and do below



Anyway for what it is worth Let us know if such a hack worked in your case (with pics) and if not if you have a work around (with pics)

[felixbrucker]

as the connector on the PSU got burned and it has warranty ill just RMA it, thanks though, might come in handy for others without warranty

cheers

as reference the burned connector, gpu side is fine:
