PSU (Power Supply Unit)

DEFINITION
A Power Supply Unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. Modern personal computers universally use switched-mode power supplies. Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the mains voltage.
Most modern desktop personal computer power supplies conform to the ATX specification, which includes form factor and voltage tolerances. While an ATX power supply is connected to the mains supply, it always provides a 5 V standby (5VSB) voltage so that the standby functions on the computer and certain peripherals are powered. ATX power supplies are turned on and off by a signal from the motherboard. They also provide a signal to the motherboard to indicate when the DC voltages are in spec, so that the computer is able to safely power up and boot.
FUNCTION
The function of power unit is to convert the electrical power (AC) comes from wall socket to a suitable type and voltage (DC) so that each component of a computer works properly. Luck of proper supply of power will damage a computer system. The power supply receives 120 or 230V and converts into 3.3V, 5.5V and 12V. Why different converted power? That is because all components of a computer system don’t need the same power. For example, motherboard and cards use 3.3V. The most power demand parts such as Fan and drives need 12V to operate.
THE SENTENCE : I have a power supply unit (psu) with 500watt pure power. i use my PSU to my computer. without PSU my computer can't work.

Belitung, God's beautifull creations (From South Sumatera)












All citizens of Indonesia are must going to the Belitung island.

Natural atmosphere in there, still original & clean without litter.

The beach really white sand, with no stain at all.

The sea water is so clear, like a painting that is blue colored.

Underwater life there still original, coral reefs are still very tight and neat (i'm not have underwater camera so I can not share it to you)

The people there were nice and honest. no matter what we want to know immediately answered with accurate. they don't lying to tourism.

Life there is very conducive. Christian and Muslim citizens can mutually harmonious and mutual cooperation. even the family home of Mr. Ahok (Basuki Tjahaya Purnama) in Gantong belitung east near museum said Andrea Hirata front of the mosque, so adzan it's audible.

Actually, many things that can explore on the Belitung island, especially the beauty of the island and underwater.

When I visited, there were circumstances in the ocean tide - pair, even when I want to cross to the island galangal aja waves can be touched until 2 meters, so awful...

But I'm not dissapointed anyway, all paid off at the natural beauty there. on the same beach or view of underwater.

I promise myself at my own if I have go back again. with preparation very mature. because there are still many place has not explored on the island.

To be sure I really need that support equipment, such as underwater cameras and diving gear pocket. because the majority of Belitung is the sea and islands.

a suitable time if you want a vacation to belitung is currently March - July. August still secure because not go in the rainy season and the sea was calm.

If the sea is calm you can get to many of the islands, such as pig island, sand island, home belitung long in the east and much more.

Final words, I want to say, thank God... it's very beautiful creations of God. thank you for giving an opportunity for me, my family to watching the beautiful creations of this island.
