Hello Everyone,

I built a PC 15 months ago that has worked absolutely flawless up until tonight. I shutdown the PC and about one hour later I attempted to boot up, and the PC was receiving absolutely zero power. I tried multiple times, and nothing. I checked to see if the PSU fan would even spin, and it was completely lifeless. I believe I have a fried PSU. Luckily it's still under warranty, but I made a few recent changes to the setup of my PC that may of led to the PSU failure, and I was hoping someone could tell me if these caused the PSU failure (If it even is a PSU failure). I also don't currently have a spare PSU to try to see if it could be the MOBO, but I am working on that.


The recent changes made:
1) I recently moved my PC across my room, where no 3 pin outlet is located, so I had to use a single outlet orange 50 ft extension cord which connected to my surge protector outlet strip. To this strip I connect, 2 monitor, my PC, and my Macbook Pro Charger.

2) I recently added a 2nd monitor into my setup. Since then I've been having weird issues w/ my PC that signaled the oncoming PSU failure. For example, both screens completely turned white, and I wasn't able to launch task manager or anything. Only after a Hard Restart was I able to log back into windows. Another signal was while launching a game, my computer just suddenly turned off w/o my command.


Any help will be appreciated, thank you in advance!

p.s. both my motherboard and my PSU have 3 year warranties. Is this type of issue valid to RMA?
