Is My PSU Frying Motherboards ?

[CJsGamings]

Hi, I Think My PSU Is Frying My Motherboards

 

I Have An Evo Labs Cronus 850w 80+ Bronze Modular PSU

 

I Was Running A Gigabyte PA-G55-USB3 Mobo For Years With No Problems, I Decided To Upgrade To An Msi Tomahawk Arctic H270 (1151).

 

It Ran Fine For About An Hour Then My PC Hard Crashed And The Mobo Now Powers For A Split Second Then Immediatley Dies,

I Thought I Just Had A Bad Mobo So I Purchased A Gigabyte B250-HD3P, All Was Working Well For About Half An Hour Then The Same Hard Shutdown

Happened And Now Powers On For A Split Second Then Immediatley Dies, Just Like My Msi.

 

So Is My PSU Bad ? Can It Appear To Be Working Properly But Frying My Mobo's ?

 

I Just Don't Want To Keep Wasting Money Killing Boards.

 

Ram - 1x8GB Corsair Dominator Platinum 3000Mhz DDR4

Storage - Samsung 960 Evo 250GB M.2 SSD / Segate Baracuda 2TB HDD

Case - Fractal Design Refine R5

Could be, could also be a short somewhere.

Have you tried to power everything up outside the case? As in, place mobo on phonebook, attach only the stuff needed to power up, and see what happens?

I was inclined to say you had VERY bad luck with those two new boards, but if that's not the case, I don't know what could be happening. Why would it fry two new motherboards, but not the one you were previously using? Make sure that there is nothing that could be damaging the board. I had a friend who built a PC a few years back, and his motherboard died. I gave him a motherboard I had, which was the same socket, and it died too. We found that one of the molex connectors had the pins sticking out of the connector, and were touching the case, and shorting the motherboard. The motherboard I gave him, was pretty dead, however, the one he owned started working again, after leaving the CMOS battery out for a good 10 minutes. Try that.

Update, have ordered another mobo and a new thermaltake 700w modular psu, fingers crossed.

 

Will report back after I've bench built it

Okay New Equipment Arrived A Few Days Ago And I Benched And Built It Yesterday.

 

No Problems At All, So It Looks Like It Was My PSU Frying Mobo's And CPU's.
