Sapphire r9 290 tri-x 'Black Screen of Death' when stressed

This may be the most frustrating computer problem I've ever encountered. I've had components straight-up die on me before, but never have I seen anything like this.

A few months ago I built a new system with a Sapphire r9 290 tri-x GPU. I do not suffer from the apparently far more common issue of black screen on startup. No, I manage to cause a catastrophic system crash (not crash to desktop) to a black screen with a high pitched squeal coming out of my speakers when I over-stress the card. 95% of the time it works like a dream. But when I'm really stressing the card, say with ARMA 3, a large Planetary Annihilation map in late game, or or doing the 4k benchmark on 3DMark, I will get the problem. Up until the point of failure everything runs beautifully with no noticeable artifacting, frame skipping, lag, whatever.

Thoughts?

System:
Intel Core i5-4690K 3.5GHz Quad-Core Processor
Gigabyte GA-Z97X-UD3H-BK ATX LGA1150 Motherboard
Kingston HyperX Fury Blue 8GB (1 x 8GB) DDR3-1866 Memory
Sapphire Radeon R9 290 4GB Tri-X Video Card
EVGA SuperNOVA NEX 750W 80+ Gold Certified Fully-Modular ATX Power Supply
1 SSD + 2 7200RPM HDDs
Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler

The clock is stock and nothing appears to be anywhere close to overheating.

I have considered power being an issue from the PSU itself (if the tri-x has random power spikes or something that causes the system to suffer a shortage) but never it being an issue from the wall. How would one test the outlet?
 
go to the circuit breaker and see what circuit you outlet is on and how much that circuit can supply. then find out what else is is on that circuit and how many amps are being used by those devices, and see if that leaves enough amps for your power supply which will want around 6.5 amps. I have seen overloaded circuits incapable of supplying 3.5 Amps, so this is certainly as possibility.

Correct me if I am wrong, but wouldn't the circuit breaker trip if the system tried to draw too much power?

Unless you have good quality ones, yes.

Usually cheap ones heatup and burn a little so they never break off.
