PCI-E Melted

[keikeimok]

I've got one of the PCI-E 8 pin melted on one of the HD 7990 Plug. Pretty scary as I noticed white smoke and burning smells from the fans.

I've changed to new cable now and wonder if that was the problem of poor connections or what....

Thank god I was at home, or it will be a disaster. Dun wanna burn my house with that.

Thats scary, i never did like OCZ's stuff, is the card ok?

both of them are ok...

before this happened, my window will hang anytime it likes, I was thinking it might be the drivers.
After a clean install, things aren't improving.

I think that was the signs and symptoms of this kind of problems.

i'd be looking at one of these


YOUR BASKET
1 x Corsair AX1200i Digital ATX '80 Plus Platinum' Modular Power Supply (CP-9020008-UK) £259.99
1 x Antec High Current Pro 1200W Modular '80 Plus Gold' Power Supply £239.99
1 x Seasonic X-Series 1250w '80 Plus Gold' Modular Power Supply £219.95

Yep, those PSU are top of the line, I've been using this OCZ for 1 year without problems. I was thinking if I really need to change it.

I dunno if there is a problem of the PSU, shouldn't be the plug at the PSU side be melting?

What motherboard was you using? Also how overclocked are they?

I just asked on the Johnnyguru forums, and someone mentioned excessive current draw through the connector.

I am using ASUS Z87 Deluxe. I am not overclocking at the momment, not even the GPU, this thing really put me on the edge. I kept looking at the plugs from the windows from time to time now and sniff on the exhaust for any smells too.

>.<

It will be a faulty connector.

If the metal contacts do not make a secure connection this increases the resistance at the junction and will cause the pins to get very hot very quickly when you draw a high current. Either that or a wire not properly crimped to the connection will cause this.

Common with industrial breakers etc. which when cables aren't tight.

Nothing to do with the PSU output, purely a connection issue.

wow, that soothe a bit of my nerves. but how do I know if they are tight enough? Is there any test apart from that scary white smoky test I 've got yesterday night?

 

[keikeimok]

so it was a design flaws then....I am stuck with the card now, dunno what I can do with them.
RMA to MSI?

hopefully .... but It won't be 24/7 anymore ever again with any of my computers at home. I use them mostly for mining after non-gaming hours....
