And the CPU socket is toasted

I am trying to think of any other possible cause. If CPU is toasted it should not even boot. I just don't understand when unplugging VRM can lead to booting up but no display signal

Are you sure the machine is actually booting and not just powering on and not actually POSTing?

Without power to the CPU VRMs, the CPU shouldn't be able to initialize. So no POST should be happening.

Also, the two 8-pin plugs don't go to two different VRMs. They both power the same VRMs, the machine will work just fine with just one plugged in.

The reason the computer powers off when you have one or both of the 8-pin plugs is plugged in is because whatever failed went dead short, which is tripping the over current protection.

So I assume (hope) it is the MoBo VRM that is shot?
 
I believe the RMA will go fine.
I say this due to an RMA problem I had with an Asus board (CHV) that died within three weeks of getting it new and did the RMA. Got the replacement in and guess what?
Was dead right out of the box itself.

Contacted them again and they said "Send it back" so I did and when the third one arrived it worked fine. Things is for me Asus made sure I had a working board in the end even though it seemed like a crappy process - Which it was concerning a replacement itself being dead when received BUT as said they made sure I had a working unit at the end so... Can't really complain here.
I don't know about RMA's from let's say...... ASRock for example. I've heard horror stories about their RMA process but in fact cannot say if true or not because I've never had to do one with them before.

Good luck and if it's replacement doesn't work, just say so like I did and I believe they'll work to make it right in the end.
 
This is the firs

Still that sucks. And shipping cost does pile up fast.

Heh, my friend had exactly the same thing with his CHV-Z. Then he just thought "screw this" and changed to Intel platform.

That was the only bad thing of it but in the end I had a working unit..... However with the costs of shipping thrown in with the original purchase price and all it was more than it should have been BUT I did get a shipping voucher the second time that covered shipping costs.

You do have to ask for it but in most cases they'll do it to keep you as a happy customer.

More than likely yes. I've had it happen a few times. Unfortunately, it is possible that when the VRM failed, it also killed the CPU. The two times I've had VRMs die on the motherboard, the CPU was killed too. Basically, if a part of the VRM when dead short, it was likely sending 12v straight to the CPU, which usually kills it. You might have got lucky, but I'd be preparing to RMA the CPU too.

I got CPU 2nd hand, so chances are if CPU is fried i am out of luck.
 
ASUS got my MoBo in their service department. They promised to finish within 7~10 days either for repair or replacement. And the replacement is "dependent on the availability of motherboard at service center"

This kinda sucks, since the TUF X99 was the 1st gen X99 that came out in 2015 they may no longer have any in their service center. I hope they don't give me something worse than the TUF X99.

Typically, when this happens and a reputable company is involved, you end up with the next tier up or the next generation. So in other words, you usually end up ahead. Of course, that assumes they are able to duplicate the problem there and are unable to fix it, or it is not economically feasible to fix it.
 
Praying to the PC god that it is the motherboard problem. If it is a dead CPU i will be fucked for sure. Might have to sell some components to help pay for the repair.

That reminds of the one time I had a Athlon 64 3200+ fry when one of the mosfets popped on a nForce3 250gb Gigabyte motherboard. Nothing gets your attention faster than hearing a loud pop.

This board: GIGABYTE GA-K8NSC-939

Turning on a Enermax PSU that died on me this way once. POP!!! And it was over....:ohwell:

But when this mosfet went it literally blew itself free from the board except for the two legs still soldered. Went from laying flat against the board to standing up right.
 
Quick update. Called and chat with ASUS RMA customer service.

They are able to replicate the exact issue. Infinite boot looping. Board is 100% toasted. I asked them regarding the "killing CPU" with it. The RMA guy had no idea so I was left on hold for ~20 minutes while he called one of their tech guy. Response was as long as I am on BIOS 3505 or 3701 the over current protection should prevent anything like that from happening.

Since the original board is beyond repair, they will ship out a replacement board to me. Only problem is they don't have TUF X99 in stock at the Indiana warehouse. RMA guy says the replacement board will be equal or greater value based on whatever is available at that warehouse. So this is kinda shitty now, since they can claim any of their X99 to be equal or greater value. And I will probably lose my Windows 10 Pro license since it is tied to that motherboard. On top of all that it will probably be next week that they can ship out a replacement to me. So a total of 1 month of down time, assuming the replacement actually works. Not fun at all. Not even a little bit.

You can call the activation service if you have to re-activate. You are allowed to change out the motherboard with a similar one in the case that the original motherboard has failed.
 
Is it an upgraded Win 7 Pro OEM license? If it's a purchased windows 10 pri licene it likely is a retail license.
