Stuff's Melting Help

[tomtor900]

I was gaming. Smelt burning. Looked down. Molex connector is melting.

Its on an 8 pin to (double) molex adapter on the graphics card to PSU

Only one of the molex was plugged in 

It's melted

 

Corsair CX450M

Asus GTX 970

 

One guy had this problem but he had a crappy psu and i feel like this isn't my issue.

Another guy said on that post that connecting both molex's would share the power load and prevent overheating

Please help lads and ladies

Don't use adapters in the first place? Your PSU has the connections for any GTX 970 out of the box....

Sounds like the card was drawing more power than the cable could provide.

I never trust the molex to 6/8-pins. If your PSU doesn't come with any 6 or 8 pins it's already an indicator that it can't handle a very powerful GPU.

Sounds like someone that doesn't know what they're talking about. 

Don't use adapters, use the PCIe connectors on the PSU. The 970 is a 145W card, there will be no overheating.

That Corsair CX450M has the 8PIN power built in as mentioned before.

If it you use it for another PCI/PCI-E card using that Molex adapter isn't a good idea at all!

Getting a more powerful PSU would have been better, besides that someone didn't know how a power supply worked.

1 or 2 Molex plugs they still come from the same source, granted it might lessen the stress on the actual wire .. but that usually doesn't matter.

 

I'd replace the PSU.

Most certainly stop using the system!

Any further melting could short something out breaking that GTX970 or worse.

Next time remember this golden trick :

Dongles & Adapters are all fun 'n' games, until you realize they are made to fix a problem you created.

 

Apple could learn a thing .. or two .. or three from that.

i used another molex adapter, plugging both molex's in. it doesnt melt now it just crashes

Did you never learn Ohm's law in school?

 

Molex melted because resistance of the adapter created heat.

 

Different Molex causes crashing because resistance causes drop in voltage.

 

DO NOT DO NOT DO NOT DO NOT use adapters!!!!!!!!!!

 

The CX450M has a PCIe cable.  Why in the wide world of sports would you even THINK about using an adapter??????????

If they were 2 separate Molex chains and the cabling was done properly He would be correct, though adapters in general are kinda dumb.

could you link me a picture of the pcie cable i need

[airdeano]

the cable on the far left is a 6+2 PCIe harness to use, the other end plugs into the PSU '6+2 PCIE' (8-pin connector)

i plugged that one in and my games just run stupidly slow. just to confirm i plug the six pin and 2 pin together on the gpu and the 8 pin on psu

Yes, that is exactly what you want to do.

 

Also, it causing your games to "run stupidly slow" isn't actually possible. It's either an unrelated issue or just in your head.

well ive done that and im not imagining things. 60 fps down to 10 since this whole issue started

Are you sure you didn't switch to integrated graphics somehow? As said, power is power. The cable will not slow down your GPU.

[tomtor900]

how would i tell if i switched to integrated

also how do i switch back
