Sama ada gambar ini betul asli atau hanya 'trick' photoshop, terpulang lah kepada pandangan masing-masing. Bagi aku, jikalau gambar 'capasitor' ini betul ia adalah merbahaya. Mengapa mereka buat begini ?. Sudah pasti lah untuk jimat kos supaya barangan boleh dijual dengan harga yang murah. Kapasitor seperti ini terdapat pada hampir semua barangan elektronik termasuk komputer.
Kepada sesiapa yang beli barangan elektronik buatan China, anda kena terima hakikat yang Kapasitor seperti dalam gambar itu mungkin ada didalam barangan yang anda beli. Anda juga perlu lah bersedia untuk beli barangan yang baru, kerana kalau rosak, samaada tak boleh diperbaiki langsung atau kalau boleh 'repair' pun, nanti kos nya tak balik modal, lebih mahal dari beli baru.

Note:
The Equipment it is used in might even work normally for some time.
How long all depends upon how both the equipment and the 2200ВµF capacitor are designed.
Well designed equipment will usually put less then 40V on a 50V part (and a good 35V Device will do at 40 or even 50V for some time unless it operates in hot environment), and given adequate mains voltage and normal temperature, it will work even with 1/3 of the capacitance at modest load.
Now if the mains voltage falls to say, 215V instad of 230V (perfectly within the +-10% specification), temperature goes outside normal levels or load simply increases near maximum, the capacitor wont properly filter the voltage and all sorts of malfunctions will result.
Which can result in all sorts of damage depending on what sort of equipment is concerned.
