Here's what I've got:
i5 760
Gigabyte H55M S2H
4 gigs ram
Gigabyte Geforce GTX 650ti 2GB
crappy 500W psu

Since few days while playing games like BF3,FC3 I was getting display driver failure errors and the games crashed.The temps recorded were:
CPU:75 degrees C(I usually play at this temp)
GPU:50 degrees C
Yesterday I smelled something burning and slight cracking noise was heard and it was molex connector going to the graphics card.
Since the molex connectors available are not enough for me,I use Y splitter.
One molex connector is splitted in to 2, one of which goes to the 6 pin of the card and the other to the case fan.
Another molex goes directly to the 6 pin connector of the card which was melted. So for now I've disconnected another case fan(I've 2 case fans) and used that molex to 6 pin. Also I'm unable to resume my pc from standby or sleep.(Its the unshared connector which melted not the splitter one).

Kind of noise is heard from motherboard and orange light appears which means it is trying to resume but then it fails.Have to the switch off and then back on in order to start the pc.


My question is why did the molex melt(I've been using that card for 9 months without any problems).And is it safe to play games or will that another molex also melt??Cus it is the only 4 pin connector left.Does it mean my psu is getting overloaded and is about to die??

Hi
If you are going to use molex to 6 pin adaptor cables for high power draw graphics cards you need to get cables that have two molex connectors to one 6 pin connector,this is to prevent the molex from being overloaded and melting.
