Upgraded card, Lost stability, now system crashing

post #1 of 6
Thread Starter 
Hi! First off:

MSI 870-G45 AM3 AMD 770 ATX AMD Motherboard
AMD Phenom II X4 955 Black Edition Deneb 3.2GHz Socket AM3 125W Quad-Core Processor
500W Power supply
APEVIA X-JUPITER ATX Full Tower Case

Went from a Geforce GT 520 to:
Geforce GTX 560

The computer is set up well to overclock, case has 4 fans and the mother board is loaded with nice overclock features. Before i upgraded video card, i had to CPU overclocked from 3.2 to 3.8 with no issues and low temps. After install i can only run the computer stable at 2.5.

If you look at motherboard I linked above you see the South bridge sits right where the video card would be. My old card was small so this wasnt an issue. The new card covers 70% of the South bridge with less than a cm of distance between the card and the heat sink from bridge.

If i run at 2.8 or higher the machine will shut down a few minutes into anything high performance (gaming). Idols fine with no issues, although the south bridge at idol is near 40C before i start gaming and quickly rises, so i figured the issue was the mother board was overheating and a thermal shut down was happening during high performance.

I opened the side of the case and placed a large 2 feet by 2 feet floor fan nearby and ran it. South bridge temp dropped from 40C to about 26C so i thought for sure i could run back at 3.2 as a test. However a couple minutes in the system restarted again and i could smell something burning.

I'm stuck trying to determine if the problem is heat or if its Power. The new card required 2 black 6 pins from PSU and specs ask for 450W power supply. Worried between the new card and all the case fans, CPU, etc that during high performance im just not getting enough power to sustain the build.

Looking for help on 2 fronts; Need advice on setting this system up with better cooling, and curious if my problem might be power related.

If its just heat, i can upgrade CPU heatsink/fan (could use advice on a good one for this system) and add a top mount fan blowing in, if its power ill need to upgrade to higher Watt power supply. Dont want to upgrade power supply unless it's necessary.

Also, i was thinking i could move Video card to bottom mother board slot. Pro is its away from the South Bridge, Con is the fan will sit less than an inch from bottom of case so card temp might go up. Will leaving top slot empty and placing card on bottom effect card graphic capability any?

Thanks for any help and advice!

Have you tried putting the 520 back in to see if you can reach the same overclock, or even the stock speeds?

I used to have that case and power supply. It is a TERRIBLE power supply and would not power my rig when I went from an 8600GTS to an 8800GT. THE GTX 560 Ti consumes a lot more power than the 8800GT. It is not watts that matter, it is amps on the +12V rail that you need to look at. Get a quality ~550W unit and you will be fine. My Antec 550w PSU has served me fine for over 4 years.

Got a nice 750W replacement so i can SLI in the future. Computer running like a dream now, exactly like you said it was the +12V rail.

Did you install the option top fan on your case? Debating if i want it or not and if i want it bring in air or pushing out.

Top fans always exhaust the hot rising air.

Yeah ... never, ever buy a case with a power supply included ... the one's that come installed in cases are always total crap.

I take it back, there's been a few really high-end cases over the years that have come out with decent PSU's included, but it's very rare. Any Case/PSU combo that's <$175 is pretty much certain to contain a garbage PSU in it.
