this may be stuppid but hey it happened to me! lol
How much wattage you getting from it?
for me i had my first gaming rig that i had built, and as for doing the research i KNEW that i had enough juice to power my baby, but to no avail, then after a good 2 months, and ALOT of posting on here and other sites, and talking to friends, no one could figur out what was wrong....
it would turn off randomly etc...but mainly also when gaming or using photoshop and programs like that.....so after trying MANY solutions including sending back SSD etc....
at my last moments sanity, my brain said "hmm whats this little jumper back here on the psu " ....i wonder if.............
FLIP!
wait for it............wait for it..............
SUCCESS! lol
my system wasnt getting enough power because the lil red switch at the back was at a lower setting. lol GOD i felt so dumb lol
so you may wanna check that....im just saying lol
