I'm in Canada, bought it with the corresponding (US) power supply, just received it, plugged it into a wall outlet, made sure the power supply is on... And when I turn it on, it shuts off before even fully booting. Not at any specific point in booting, either, it just seems like the power cuts off. Sometimes, if I turn it back on soon after, it barely stays on for two seconds. Tried a different outlet with the same result. Nothing else seems out of the ordinary, fans are a bit loud, but not so much that it seems strange for a booting computer.

Made a support ticket but it seems like service may be slow until Monday. Anyone ever experienced something like this?
