MSI HD7770 suddenly dies after 6 months (CoolerMaster extreme 550W)

Stripes and points after setup post, then Black screen.
Now, mi friend tells me it was the PSU not giving the needed power to GPU, I disagre with him.
What do you think ?

His specs are :
Gigabyte GA-B75M-D3V
i3 3220
4GB 2x2GB Kingston hyper Blu
MSI HD7770
CoolerMaster Extreme Power Plus 550W made by SEVENTEAM

    I would treat that as more of a 400-450 watt power supply due to design limits.

    I do not think that should be an issue given the cards lower power requirements(i would personally run that card/cpu on a 300-350 watt power supply, hell I am running a GTX 650 ti on a 300 watt typing this.).

    Do not get me wrong, coolermaster has a bad reputation for releasing under performing power supplies for a reason. As long as it is treated like a 400-450 watt unit, it should work without damaging things. Even worse defects can simply happen making a not so good unit into an outright bad unit.

    then do you think it just a GPU faulty unit, I now that PSU is overated, but still enough for that rig I think.

  3. I am guessing it is a gpu fault. It sucks, but does happen.

    Your system should honestly have a hard time pulling 200 watts at the wall.
  4. I got mi friend just besides me, he is really ATI disapointed, cause others ATI faults has ocurred to him on the past (HD3850,HD4850X2, and now MSI HD7770)
    He has been sponsored by me, so I disapointed to ATI too , What do you think ? I have a Sapphire HD7850 with no issues till now .
  5. I have actually had good luck with video cards in general. last 2 failures I had have been.

    GTX 670(this sucks because it failed[crashing in games and folding@home] within a few months)
    Geforce 4 4200ti agp <- yeah that was the last one before the 670.

    So my x850 pro flashed to xt, x1900xt, 4870, 5770, 5870(this card is a work horse, used it for years) all still work. all of those cards are reference designs.

    On the Nvidia side I still have many old Geforce 2's the replacement 4 ti 4200(fan failed, but the card was fine.) a 4mx 400, 8800GTX 650 ti and the current 670.

    You may see a jump with less Nvidia cards(8800gtx -> 650 ti), but Vista drivers from Nvidia DID leave a bad taste in my mouth(600 dollar card with NO support and just one crashy driver for over 9 months). I would have blamed Vista if I did not have other cards to test with, but it was actually a driver thing, my X1900XT(and its lower performance compared to the 8800gtx) had to be used since I did not have money to grab another card and the 2900's from amd had been power hogs for sure.

    So yeah, overall only 2 actual card failures in all this time.

    OK, I gess is a matter of having good luck then, whatever ATI or Nvidia
  7. I think so. At current both seem to have decent cards(but the R9 cards seem to take heat to a new level, but the gtx 4xx cards got hot too), but I never had ANY 7XXX cards to rest with personally. I had wanted a 7770, but the gtx 650 ti with MSI's cyclone cooler was too tempting for its quiet operation and lower power consumption when playing back videos(since that is my media center pc, that was what I wanted. amd did have more video filtering options on its cards however).
