I never buy a AS before but given the number of their PC in my workshop.
To my knowledge what part they use in their build are not really known to users.
Unless you customize the individual part but than they can last minute swap/change
which I also heard before.
Like most here mentioned if want quality build go Sim Lim, Aftershock is like that.
Source cheap than sell high but than how many times you have to repair is another question.
Some user like you is PSU blow, while some are faulty/brick motherboard as they use
their own custom BIOS.
If you start the PC and see a Aftershock logo the motherboard is using their BIOS.
The mobo BIOS tend to have issues down the road thus I do have cases of
their mobo bricking and no way to save it except RMA.
If you wonder what is mobo bricking, it is a issue when you start the PC.
No display even though the PC is running, you swap RAM, GPU but
it refuse to start.
I think I did post a thread about Aftershock rubbish quality in HWC.
