When you begin dealing with electrical outlets, you want to take some safety measures, and PCs are no exemption. Their internal power supplies utilize many watts and are set to utilize over 100 volts. You can harm yourself badly if you handle PC inappropriately.
Dealing with Hardware
1 If you want to hold parts in PC, ensure that those are detached, not just turned off. You can bump power button as your hand is in, or you could touch a bare wire and be in for a nasty shock, or worse.
The Power Supply
2. Never open a power supply unit (PSU) if you are qualified to work with one. Their capacitors keep electrical power even when PSU is detached, and this energy can stay potent for weeks, even months. If PSU is broken, take it to a technician or change it overall.
3. A switch on back of clout supply has two voltage settings. In North America and Japan, select the lower setting, which are either 110 or 115 volts. The other setting permits two times as much voltage. Using incorrect setting can grounds a unsafe surge.
4.That third lower point on end of power cable is "ground pin." In many cases, this balances out unanticipated voltage surges, which are in its place partly diverted into earth, in many cases, with a wire that leads straight from socket into soil under a home or industry. Without grounding, a device is mainly vulnerable to power surges.
Protecting Your Computer
5.Maintain PC safe from electrical problems. A surge protector power strip is highly suggested. Though, many of these are intended to hold only one surge and should be replaced later. You can also obtain a UPS for long-term surge protection.
