Hey OCN,

So I have recently upgraded my rig, I got a new MSI gaming mobo should be one of the newest on the market, the AMD R9 290, and an Intel i7-4770k processor along already have 16 gigs of DDR3 RAM, the computer ran fine in the beginning (approx 2 months ago since I got it all and installed it), but now when I play BF4 I get a weird smell of burning rubber coming from my PC (I'd say from my PSU fan. The only old component is the PSU which is a 750W old PSU (I know being cheap when it comes to getting a PSU as well is a bad move, but I wanted to see if it could manage the newer components), I am by no means an expert on the topic, but from doing a little reading I think it might be the PSU burning up, (NOTE: only occurs when playing BF4 on near max settings - game runs fine but burning smell occurs). For now the computer seems to be running fine, game runs fine, even BF4 when the burning smell occurs, I just want someone to confirm if it's the PSU or if it might be something else, additionally, if my PSU burned out, what harm would come from that other than the fact that the PSU would be dead? any suggestions on a new PSU I should get?

Thanks for reading!

Hard to say. It could be grease from a fan burning up or something like that. If I was in your shoes and I felt like it was the PSU making the smell, I'd replace the PSU... But that's just me.. being you lol.

Which PSU you dont list anything but wattage

This is the PSU I use currently is this: http://www.singular.com.cy/en/inter-tech-combat-power-cpm-750w-power-supply-atx12v-2.2-ac-230v-750watt-active-pfc-88882084.html

I don't know if this is an updated version, but mine is approximately 6 years old and it's a 750 Watt Combat Power PSU from Inter Tech.

Additionally, I just had a match of BF4 I wasn't running my program OpenHardwareMonitor so the fans were all running normally, halfway through the match the smell came started again, all of a sudden my screen goes black, and my monitor came up with its own version of the "no signal", lights were still on, on the cabinet of the computer and fans were still running, but nothing on the screen whatsoever, so i had to restart.

Throw it away ASAP before it kills your PC

Get something decent thats not a fire hazard

Thanks for the reply Shilka, I see your from Denmark as well, mind if we go talk about this somewhere? I'd really like to know your input etc. perhaps skype, or could you perhaps elaborate a little bit?

 

[shilka]

Yes i have skype

But the short answer is you have a no name PSU and its even a no name PSU i have seen before

No you should not keep its cheap crap and thats been easy on it

Smash it with a hammer and light it on fire

Stop using that crap no-name PSU.

I don't know of anything in a PSU made of rubber, except for a rubber o-ring inside the fan, and that won't stink unless it's completely unlubricated. But burning epoxy can smell like burning rubber, and the circuit board and packaging for the chips, diodes, and transistors are epoxy. If a power diode or transistor isn't firmly attached to its heatsink, it can overheat.
