X51 Absolutely No Power
About one week ago, I was playing FFXIV when suddenly my PC shutoff. When I tried to turn it back on, nothing happened. I checked the power supply but I didn't know where the problem was. Pulled out the multimeter and tested the power supply, which for this computer is basically like a laptop charger, and it seemed like it was only outputting 4V. With nothing else to really go on, I assumed this was the problem and ordered a new power supply. It arrived and I tried it, but still no power. I thought maybe the power button might be broken, so I tried turning the PC on without the power button, but still nothing. I've checked throughout the system to see if anything was loose or broken, but I haven't seen anything different. I got this PC about 2 years ago from a friend who had no problems with it. Everything in it is stock except for my HDD and I've occasionally taken it apart to clean it. I really don't have the money, as a broke college student, to buy a new PC, so I'm trying my hardest to fix this but I'm stuck. Any help would be appreciated, thank you.

The problem was the internal powerboard. Moved the mobo to an old case of mine and hooked it up to a standard power supply and it works. She's alive again! Thanks everyone for all the suggestios, I didn't realize that there even was a power board at first, though I still couldn't see anything wrong with it it must have failed.

Hi Jyrz.
maybe the internal Power Board failed? open the Case and push the Power On Button. can you see or hear something like Fans and HDDs spin or LEDs blinking?
also try to remove the Graphics Card and Boot with the Intel GPU. connect the Monitor streight to the Motherboard.
have you tried to Clear CMOS? disconnect all Cables, remove the CMOS Battery and hold Power On Button for a Minute. then install the Battery and try to Boot.

my guess would be the video card but without knowing what version R1/R2/R3 i cant say for sure cause R1 and R2 versions you can remove the video card and boot off the onboard and see if it posts with the discrete(nvidia or amd) card removed .. the R3 won't post auto to the onboard for some reason, unless its set in bios .
if you have another video card to try would work aswell .. this is what i did when mine did similar to yours and fired up my 970 gtx had torched, and smelt like it too lol ..
i have a X51 R3 i7 6700/970 gtx
other case can be the internal powerboard (the R1 was bad in this area apparently) or other issues but without knowing the exact revision and or specs..

What is the DC-voltage being outputted from the new AC-Adapter?
As a back-track check, what is the DC-voltage being outputted from the OLD AC-Adapter?
Yes, it's like a laptop power-system. The Power-Board inside the x51 is a DC-DC_Converter. Like a conventional desktop, you should be able to test Power-Supply with a $20 Digital Power Supply Tester.
