Something smells like burning - Page 2

post #11 of 15
Check the 24 pin connector that you plugged into the motherboard, aswell as the 4/8 pin connector that you plugged into the motherboard. I've seen alot of instances where the pins have melted in the sockets.

PSU fan or other fan seized or straining and causing the smell.

It sounds like something is being overloaded somewhere, and it probably will pop eventually. The PSU is a good candidate for where the smell is coming from. Is this on your sig rig? if so, i could tot up the power requirements, and see if you are running the PSU near the edge?

yes it is the one in my sig rig,

it only seems to smell when its under full load, BF3 and F@H and the 2 things that make it smell the most, I think its coming from the PSU thats where it kinda smells when I turned it off and look around...... well, going to buy a replacement tomorrw, thanx for the help guys biggrin.gif

Right - An OC FX-8150 can draw just over 450W (Reference) and each card has a maximum power draw of 151W at full load. (Reference - scroll down to the chart)

It's safe to assume when gaming or folding, with your over clock, you will be pulling peaks of 450+151+151=752Watts. That means you are running really close to the wind with that PSU, and probably overloading if pulling more than the recommended watts from the 12V rail. Good practice in electronlcs is to rate components at least 50% more than maximum expected power draw, which in you case means going for at least a 1128W PSU - But in real terms, you'll probably get away with a DECENT 1000W PSU. Check JonnyGuru's reviews on a PSU first, and you'll not go wrong.

Hope that helps. smile.gif

and a fator not many take into account is heat as the tempiture gose up in the case it rasies the residence on componets and your psu will ramp up
