Hi, i have just bought a new Evga 780 superclocked ftw edition graphics card and Antec 750w 80+ gold high current pro power supply. Everything seemed that it is working perfectly until i started getting instant pc shutdowns. They are not caused by heavy gaming as i ran several burn tests and played metro last light for an hour. The crashes happen sometimes when i am browsing or watching a movie. sometimes it happens the second i click on the burn test for my gpu, but then i try 10 more times and it is not happening. if i try an hour later it has 50/50 chance that it will happen.
I really do not know if it is a gpu or psu problem, the temperatures on the cpu and gpu are even lower than expected on full load and the 780 draws 97% of its TDP under load so i do not think that it is underpowered.
Now the things i suspect are that the psu may be overheating, it may be faulty or i may have connected it wrong although i doubt it. The 780 needs a minimum of 42 amps on the 12v rail and the psu has 4 x 40A 12v rails so i connected 2 different 12v rails and on the case it says that the combined total output is 62A witch should be more than enough for the 780.
What do you think? Can it be a motherboard problem? i have an Asus p8p67 le and i updated the latest bios but it is from april 2013 and inside the box of the gpu it said that it is very important to update it to the latest version.
cpu: intel i5 2500k @ 4,5GHZ (tried at stock, nothing has changed)
gpu: EVGA 780 SC FTW dual bios
psu: Antec High Current Pro HCP-750 750W TX12V v2.3 / EPS12V v2.92 80 PLUS GOLD
mobo: Asus p8p67 le
ram: 8GB (4GB Kingston Hyperx 1600MHz + 4 GB Kingston 1333Mhz)
one ssd and three hdds
