Thank you very much, @Tech Inferno Fan, for your swift answer! I'll try a more powerful PSU and come back to report

I experience the same problems as @aoe2exp has described above, while using a different setup. I'll try to make it as clear as possible:
After playing approx. 10 minutes, the eGPU suddenly shuts off, leaving either a black or blue screen of death.
Observing the eGPU socket, the problem occurring looks like this [10 secs video] while playing a game:
SpoilerFor anyone interested, here are some GPU-Z logs of these crashes:

GPU-Z for GTX 770

- Multiple re-installs of OS and drivers (also via DDU and in safe mode) (problem persists)
- Test of possible driver combinations (Intel/Nvidia, Intel/AMD/Nvidia, only Nvidia drivers installed) (problem persists)

Tried changing from Gen2 to Gen1 (problem remains, while eGPU performance decreased) (problem persists)

Isolated PSU (problem persists)
On 08/09/2016 at 4:22 AM, Tech Inferno Fan said:[...] If so and the crashes continue then do note some users isolated the PSU from other devices(own power point, away from other electronics like fridges/stereos) to eliminate spikes in power delivery to the video card. [...]

Tried different chainloader modes (problem persists)
- Tried replacing the 6-pin cable (from PE4C to GTX770) with the 6-pin cable from PSU (to GTX770) (problem persists)
- Tried different games (problem persists)
- Tried PE4C v3.0's "Force Power On" bypass (problem persists)
- Tried hot-plugging (card cannot be used and fans spin on full blast, card works when plugged in when booting)
Possible Approaches?
- Replace the PSU with a more powerful one?
- I've read about fuse bypassing here (though for PE4H) - could that be a possibility?
Many thank's in advance!

Thank you @Arbystrider, for your suggestion. Luckily, I could return the existing PSU and replace it with the Corsair VS450 upon @Tech Inferno Fan's suggestion.
So far, I have had no shutdowns anymore! Thank you both for your help.
It might help others, who are looking into eGPU setups, to include what one has to look for when deciding for a PSU into the FAQ (i.e. not the total wattage, but the wattage supplied via the 12V cables, as I now understood)?
