some will show you a suggest power requirement (PSU Wattage) while others will show your actual power draw. Wikimedia Commons has media related to Power supplies. Current limiting[edit] Some supplies use current limiting instead of cutting off power if overloaded. One end of the cable is soldered into the PSU’s PCB and the other end terminates in a standard connector, with no breaks in the line. news

If the SMPS uses an adequately insulated high-frequency transformer, the output will be electrically isolated from the mains; this feature is often essential for safety. Power supplies in the higher certification tiers tend to command very high prices, however. Disclaimer: Brand name computers (Dell, HP, Compaq, etc....) often use proprietary parts and connectors. The DC obtained after the capacitor oscillates a little(this oscillation is called ripple), so a voltage regulating stage is necessary,made by a zener diode (frequently with the aid of a power my company

If you have a computer that is already assembled, you can determine how big the power supply is by opening the computer case and examining the unit.

Then rectification is done by a set of diodes, transforming this AC voltage into pulsating voltage. I know the wattage but I'm unsure about connectors. Many power supply manufacturers also use the wattage of the power supply in the model number.

Corsair provides a thorough overview of power supply efficiency and of the 80 Plus program, if you'd like to learn more. I know the wattage but I'm unsure about connectors. Introduction to Bench Power Supplies - B&K Precision Understanding Linear Power Supply Operation Load Power Sources for Peak Efficiency, James Colotti, EDN 1979 October 5 Retrieved from "https://en.wikipedia.org/w/index.php?title=Power_supply&oldid=768881850" Categories: Power suppliesHidden http://outervision.com/power-supply-calculator If the output current becomes small enough, the output voltage of the power supply can reach the peak value of the secondary voltage of the transformer of the power supply.

Some power supplies are discrete, stand-alone devices, whereas others are built into larger devices along with their loads.

Whenever you introduce an additional connection between the PSU and your components—as happens with modular power supplies—you add more resistance and another potential point of failure into the line; and any http://www.coolermaster.com/power-supply-calculator/ Adapters with AC outputs may consist only of a passive transformer (plus a few diodes in DC-output adapters), or they may employ switch-mode circuitry. Power Supply Calculator Newegg A glimpse inside a PSU. Asus Power Supply Calculator Another consideration is cabling.

This effectively disconnects the power supply from its load, and the equipment stops working until the problem that caused the overload is identified and the fuse is replaced. http://simplecoverage.org/power-supply/what-power-supply.php Do your homework! Mechanical[edit] Power supplies are packaged in different ways and classified accordingly. If you want to learn even more about the internals of a PC power supply we recommend thatafter reading this tutorial,you read its sequel, Anatomy of Switching Power Supplies, where we Psu Calculator Corsair

It doesn’t help that the power-supply market is awash with products from unscrupulous manufacturers that use substandard components and overstate the hardware’s capabilities. Of course, you should also check the PSU's connectors to confirm the unit is compatible with your particular system. Efficiency10. http://simplecoverage.org/power-supply/what-kind-of-power-supply-do-i-need-for-this-setup.php The important number here is the one for sustained or continuous power, not the one for peak power.

Power is "lost" (converted to heat) when components operate in their linear regions and, consequently, switching converters are usually more efficient than linear converters because their components spend less time in Power Supply Wattage Calculator Average users with average needs should probably stick to the simple 80 Plus or the 80 Plus Bronze level unless they find a particularly juicy deal on a Silver or Gold On the other hand, a low-quality power supply can cause several intermittent problems, most of which aredifficult to solve.

The thing is, if the website recommends let say 450W (not minimum), I buy 500W.

In other words, the power supply converts the conventional 110V or 220V alternating voltage into continuous voltage used by the PC electronic components, which are +3.3 V, +5 V, +12 Vand The HD 4870 will likely take around 160w-170w under full load while hard drive, dvd drive, case fans etc will prolly add around 50watts. please help?!

The wattage of your power supply should be listed on a sticker on the unit. Since linear power supplies still use the 60 Hz (or 50 Hz, depending on the country) frequency from the power grid (which is a very low frequency), the transformer and the As an electrical device, the computer needs power in order for its components to operate properly.
