My sister''s power supply just had a capacitor explode
Do not ever open a psu if you don''t absolutely know what you are doing. Even with the power unplugged, such a capacitor can store enough energy to kill an adult. 4.7 uF at 400V are lethal. The ones in the PSU have 470uF at 400V.

What Causes a Capacitor to Explode? Common
Reverse polarity voltage and over-voltage are the two main factors that can make a capacitor explode. Compared to other types of capacitors, electrolytic capacitors are more likely to explode. In the following piece, we shall explore
Is there a footage of 400V capacitor exploding? : r/ElectroBOOM
Large, relative HV capacitors usually does not explode violently, pressure valves and overall not-so-sealed construction does not allow them to actually explode. Just 500V would not do - you
Is this 400V capacitor rating for DC or AC?
Your capacitor has plastic insulation layer. It has no defined polarity like the electrolytic capacitors have. In this application only an unpolarized and high voltage capacitor is ok because it must

6 FAQs about [400v capacitor expands and explodes]
Why did the capacitor explode?
The capacitor produced a fireball upon explosion. This oil-filled capacitor was located in an enclosed shelf unit with heavy-gauge steel perforated exterior walls. One area of the wall was exploded outward at the capacitor location ( Photo 2 ).
Can a 100uF 400V capacitor be used on a DC Circuit?
Your 100uF 400V capacitors were undoubtedly low cost aluminum electrolytic capacitors rated only for use on a DC circuit. When you connect such capacitor to the AC mains you are alternately subjecting the component to a positive peak of the 311V and then -311V at a rate of some 50 or 60 times per second.
Is exploding a capacitor a good idea?
Deliberately exploding it for fun or to see what happens is irresponsible and a waste of resource. But if you do that for whatever reason, do it in a open field with you at least 20 meters and upwind. Large capacitors are less spectacular than small ones, because they always have some kind of vent.
Do electrolytic capacitors explode?
When it comes to a capacitor exploding, the electrolytic capacitor is the most likely type to cause a spectacle compared to its counterparts. Other capacitors will not explode, but rather burn, crack, pop or smoke. The main reason why an electrolytic capacitor might explode is due to its construction.
How do I prevent a capacitor from exploding?
Don't over-volt it and don't connect it backwards. If you're still concerned about it exploding, set up a blast shield between you and the capacitor (but don't enclose it! That could act like a secondary bomb!) If you keep it within its specified operating conditions, it won't explode. Just be smart and be safe.
Did a exploding capacitor delay the development of the computer industry?
What follows is a true story of how an exploding capacitor delayed the development of part of the British computer industry by at least six months. The name of the individual involved has been withheld to avoid embarrassment. We will call him “The Young Man,” or TYM for short.
