New PSU, overheating question.

post #1 of 5
Thread Starter 
EDIT: Updates below, scroll down to my next post.

Hi guys, first post here.

Today i purchased a new 23" screen (to make 3) and a HD 7870,

I was previously running a 420kw PSU which wouldnt suffice for the 7870, so i upgraded to a 500kw PSU (cheap generic brand though).

When I switch to eyefinity and play BF3 (even on low settings) after a few minutes i start to notice a burning smell coming from my PC.
I made sure to have Core Temp and MSI afterburner open to monitor temperatures, and when not in BF3 core temp is around 50-60 (i5), however when bf3 is open in eyefinity core temp increases to around 80-85 degrees Celsius.
The burning smell and the high temperatures are worrying, so i came here to look for solutions.

I'm sure ive probably missed something so if you need any more information please request it.

Thanks in advance for help, and sorry if this is in the wrong section.

EDIT:
launched bf3 WITHOUT eyefinity and the increased heat and burning smell still occurs..

EDIT:
Rig updated in profile, as requested.

EDIT:
If the cheap PSU is the problem i will probably upgrade to this;

apparently thermaltake is a good brand.

Hmmm...........

Have you tried turning it off, then on again?
If that doesn't work, you might want to invest in some ram to cool down your system.
Other than that, I can only suggest that you throw water on your PSU next time you think its burning.
XOXO

REAGARDS,

You could start with filling in your system infrormation in your profile so we can see which i5 processor you are using, with what cpu cooler and case etc. PSU is not something to go cheap with tbh, you should have atleast gotten a Corsair 500W, those go for 39 bucks after rebate.

Ok so i bought the 500W Thermaltake PSU and the burning smell has completely been removed.
(http://ijk.com.au/branch/ijk/product_info.php?cPath=23_41&products_id=134373)

However,
The core temp of my i5 reaches high 90s after a few minutes of intense games (bf3 for example (even on low settings).
Is this a problem?
I only ask if this is a problem because if i didnt have programs open telling me that my CPU is that hot, i would never notice as the computer performs 100% correctly.

Ask the experts right?

See if you can get your hands on a non-contact thermometer. Test the side of the CPU and several place on the CPU cooler to make sure that heat is transferring properly. If not, I'd at least recommend replacing the thermal compound and seeing if that helps. Might want to go with a bigger CPU cooler too.

Good thing you got the burning smell sorted out. You're probably drawing close to 100% of your PSU's capacity, and that cheapo probably had some underrated wiring that was heating up due to the current passing through it. The cheapo PSU's always have some cut corners in manufacturing... that's why they're cheap. In the future, I'd recommend protecting your rig by not using stuff like that. You blow a PSU out, it can take other things with it, like your GPUs, mobo, etc. Not worth saving $50.
