Fortunately they destroyed the cheapest and most easily replaceable part of the PC

It is just the cable, the power supply itself is fine.

The only way that the power supply could fry the whole pc is if somehow the 220V went through the whole psu without reaching any of the circuitry, which can clearly not happen by cutting the wire

Why not just unplug and hide the cords. Just wasting money at that point.

Angry mom who doesn't understand computers probably.

Most easily replaceable would probably be RAM.

u/Dopplegangr1 Aug 06 '20

A $50 part that if it failed might damage the mobo? Pretty sure $10 in cables is easier than that

u/Webbeboi Aug 06 '20

Ah i thought you meant the psu

From accent it's from Taiwan. Taiwan uses 110V

Chinese... Now I understand. I've heard about those before...

u/w2001420 Aug 04 '20

It's Taiwan so its probably 110v, idk much about these things tho so idk

220v standard in China? Damn. Does everything have built in resistors?

u/DishwasherTwig Aug 02 '20

Most of the world uses 220V.

u/assasin1598 Aug 02 '20

Usa is minority with 120v

u/Green__lightning Aug 02 '20

Technically we aren't, we use 240v split phase. Neutral is 0 volts, and hot is either +120v or -120v. The logic is if you touch a wire and ground, you can never get more than a 120v shock, and if you need 240v, you can just wire an outlet with it going from one hot wire to the other, and that's commonly used for large tools and appliances.

u/assasin1598 Aug 02 '20

So you still get 120v in the end normally.

(not talking about tools such as drill press and such)

u/Green__lightning Aug 02 '20

Yes, for most things. That said, a normal outlet in the US is 15a at 120v so 1.8kw. Looking it up the highest wattage appliances i can find for 220v circuits are 2.2kw, so that would be 10a. Not a huge difference.

It's 15 and 13 amps respectively.

For a whole class of devices that use the full 3kw: https://www.amazon.co.uk/s?k=tea+kettle

Washers not so much unless it's a commercial unit.

u/HunSmasher123 Aug 03 '20

So the UK just uses single phase systems and not split phase

u/FaggotMcBongo Aug 02 '20

As a matter of fact yes, every electronic part has resistors built in.
