It was printed on the graphics card box. Most boards with good caps and certifications loudly advertise it including MSI as well.
Basically the military certs mean they test to see if it runs between -40F and up to a hot 200F and other tests. Maybe overblown and juding on the language think it is silly, but when most old Pentium IVs XP boxes fail these days it is caused by 2 things
1. Power supply going out
2. Caps on the board failing to provide adaquite voltage in spikes causing BSOD.
Home routers too get weak after a few years due to caps aging. True a gaming system board will be obsolete by then but I do VMware Workstation for certs on mind too and mostly run MMOs so no biggie. I have a feeling by 2020 my i7 4770K will still be competitive as cpus have leveled off in major upgrades compared to the past where 10 years meant 10,000 times faster. A 1990 386 16 MHz vs a Pentium IV was quite impressive in differences. Not true today.
