The PSU frequently trips the 5A plug fuses?
I don't have the capability to provide links directly. However, you can search for "fuse in a plug" using your preferred search engine to find relevant images or diagrams.
You need to reside in the USA just like me. This appears to be a rule for UK power cords. I was quite taken aback by these being the old glass tube fuses. The only thought that comes to mind is they're concerned about the cord igniting. Since the wires in walls are thick enough, the breaker would likely trip before an overload happens. However, the wires within a cord can be much thinner. I've stayed away from this discussion because I'm unfamiliar with these cords. Perhaps if there are various fuse sizes for different cords, someone might have mistakenly swapped them using a lower-power rated device.
the uk plugs include various safety elements
the live wire's brown color is intentionally shortened to ensure the power is cut if the plug is pulled out forcefully
the earth wire stays the longest to maintain a proper connection and prevent shocks
uk employs a ring circuit setup
the functionality is outlined below.

this method allows several high-power devices to operate simultaneously without causing balancing problems.
since the voltage here is significantly higher at 230v, all appliances must be protected by fuses.
benefits of this arrangement include the ability to disconnect power from a socket via a switch within the circuit.
most plugs can be maintained easily. the fuse safeguards both the device and the cable—such as when a computer experiences a large current surge or excessive draw, the fuse would trip and interrupt the power supply.
I believe the standard fuses for plugs were 5A, though this may have changed.
Recent updates to the electrical code specify that plugs use 3A fuses for appliances up to 700W and 13A for devices consuming between 700W and 3KW, such as washing machines, kettles, and irons.
I think 5A fuses are still available and sold.
Typical surge protectors usually contain a MOV (metal-oxide varistor) between the live and neutral lines or connectors. These MOVs react to voltage changes but do not offer protection against surges caused by inrush currents or brownouts.
The user's habit of flipping the socket or outlet switch with a foot might have triggered a spike or voltage drop. Such events can damage MOV-based surge protectors, leading to open circuits in the fuses and potentially causing the plug fuses to fail. If the surge protector was consistently placed between the socket/outlet and the PC during testing with various fuses in different rooms, this could be a contributing factor.
I can verify that the 5A fuse in the PSU's plug failed. I've consistently used a surge protector with it, even after replacing the blown fuse.
When I first realized my PC wouldn't turn on, my monitors—both connected to the surge protector—still powered and entered standby mode, if that clarifies anything.
To be honest, upon inspecting it, I'm uncertain. I'm planning to return it for repair and purchase a new PSU, hoping it won't be a problem with my current setup.
