ASUS surge protection triggered on a protected system

[BleachedFur]

My system uses an 80+ Gold 750W PSU, and it's plugged into an APC UPS, which is then plugged into a highly rated surge protector.

 

This is the first time this has happened, and it's a nearly new $115 PSU as well. I just cleaned my whole PC not long ago, so there shouldn't be any issues. No BIOS settings have been changed either.

 

Xeon E5 1650 v2 4.4Ghz 1.4v

 

SLI GTX 1070, no overclock

 

I have two SSDs and two HDDs, a 12v pump at 500L/H, and a sound card.

 

It happened when playing Fallout 4.

 

Any ideas? It's summer where I live so everyone in my apartment is likely using their AC units, but mine was off when my mobo's surge protection triggered. I only have my monitors plugged into the UPS, my speakers are plugged into a separate circuit.

What's the model (e.g. RMx 750W)?

If this has only happened once I wouldn't worry about it, ASUS Surge Protection is notoriously bad when it comes to false positives (particularly if you're overclocking).

this is the first and only time it has happened. Even when my 24-pin wasn't plugged all the way by mistake, it didn't trigger lol. It's saved a couple boards from bad PSUs in the past (on an old AM3+ board, for example).

Asus anti-surge is detecting DC surges.  Asus motherboards have no idea what's going on on the AC side of any power supply.

 

90% of the time, Asus anti-surge is total bullshit.

I fixed it, my 24-pin was super twisted. I recently cleaned and rebuilt the machine and I guess the 24-pin was twisted too hard and was pulling the connector. I untwisted it and it hasn't triggered since.

 

My motherboard was right, something was definitely wrong. Unfortunately for you I'm going to trust my motherboard than I will trust your opinions on surge support.

And

 

 

And many more.  So don't just take my word for it.

 

Just like reading software using HWInfo, CPU-Z, etc.  Unless the PSU has a PMBUS output to the motherboard, your motherboard is incapable of properly diagnosing your power supply.

Actually I found the real problem. After both my UPS and my surge protector shut off I went around my apartment building with a GFI meter. My building management recently redid the lighting and electicals inside the waste management shed and that's where the surges are coming from.

They are closed on weekends so I'll inform them of the danger tomorrow.

The Asus anti-surge has no way of monitoring the stability of the AC input to your power supply.

 

The "surges" that anti-surge detects are supposedly high transient loads through various circuits of the motherboard (i.e. via PCIe slot, via ATX12V connector, etc.) that cause enough of a voltage drop (again:  DC, not AC) for the error to persist.

 

But you keep on doing whatever you're doing....

true. But here's another example of why you're wrong. 

 

+10v on my 12v rail. What the mobo is seeing is low 12v voltage.

 

Tested in another ASUS mobo at my friend's house that gets power from a different substation (z77-A1) and he's getting 12v just fine.

And now, here's what it looks like with AC filtering enabled from my UPS. 12v normalized.

 

I forgot I had disabled AC filtering because it was causing problems with my sound system and making a buzzing noise.
