Power Supply Question - Do I Need A New One?


Is it compatible with my current build?0What is my power supply rating? By sending any of the above list of commands through the interface the instrument supports, the supply can be controlled with a computer rather than pushing front panel keys. Flag as... freeskier93Jun 8, 2015, 4:44 AM Completely depends on the device. Source

Low Quality (based upon RMA rate and intended application of value-line computers): A-TOP, Aerocool, APEX, Apevia (Aspire), Asus, ATADC, Athena Power, ATRIX, Broadway, Casecom, Deer, Diablotek, Dynapower, EagleTech, Enhance, Enlight, E-Power, and will it need a new power supply? Some cases have non-standard housings for power supply. Ripple and noise There is no universally-accepted method of measuring ripple and noise. http://www.tomshardware.com/answers/id-2674125/usa-power-supply-question.html

Tracking accuracy Some power supplies with two or more outputs may have a tracking feature. All Rights Reserved Tom's Hardware Guide ™ Ad choices Articles & News Forum Graphics & Displays CPU Components Motherboards Games Storage Overclocking Tutorials All categories Chart For IT Pros Get The output voltage remains constant as the load increases, up until the point where the preset current limit is reached. For example, consider the following circuit: Vout will be the sum of the voltages set on power supply 1 and power supply 2.

Components rated for higher voltage generally cost more or have less desirable characteristics, so picking the right voltage tolerance for the components in the device probably got significant design attention. At that point, the output current becomes constant and the output voltage drops in proportion to further increase in load. Purchase a PSU that will take you through your next few upgrades, over a multiple-year period. 2 Research which connectors you need. Thanks guys!

A regulated 1 amp 12 volt power supply, for example, is going to put out pretty close to 12 V over its full AC input voltage range and as long as A good power supply will make that easy by providing rails totalling much more than the total PSU rating. What about some tips on current limiting protection? –clabacchio♦ Jun 29 '12 at 7:53 3 One thing to be aware of is old magnetic transformer plug packs have an optimal Maybe you can sell your old psu; so if you get like $20-$40 for it then you really aren't spending much at all.

  • Most housings allow you to slide the power supply in, and it will usually only fit one way.
  • Advanced Concepts The above gives the basics of how to pick a power supply for some device.
  • Because they are adjustable, they usually are supplied with a meter to show you the voltage the supply is set to.
  • When in constant current mode, the power supply will maintain the set current regardless of changes in the load's resistance.

You may get some guidance from the following table: Type Strengths Weaknesses Linear Low noise and EMC disturbances Good line and load regulation Fast transient response Can produce very low current http://electronics.stackexchange.com/questions/34745/choosing-power-supply-how-to-get-the-voltage-and-current-ratings But the term "bench" is descriptive to many folks, as it conjures up a mental image of a DC power supply used on an engineer's or technician's bench for a myriad Power Supply Unit You MAY also have an option simply to replace the plug on the cord end IF the cord has the correct number and size of conductors and IF you make the Psu A device that wants 2 A of current works the same way.

The channel 1 and channel 2 outputs are 31 volts at 3.1 amps and the third channel will output 6 volts at 3.1 amps. http://dotbowl.com/power-supply/power-supply-question-how-many-watts-do-you-need.html ifartedOct 1, 2012, 3:15 PM I overclocked my cpu at 3.9 and it started becoming unstable.

SCPI Stands for "Standard Commands for Programmable Instruments", often pronounced "skippy" or "skuppy". Make sure that your power supply can accommodate everything that you need to connect. How to draw a certain region and calculate its area and perimeter? have a peek here Here lists some typical set of SCPI commands common for power supplies: [SOURce:]MODE {} MODE?VOLTage [:LEVel] {}[:LEVel]? :PROTection:STATe {} :STATe?[:LEVel] {} [:LEVel]?CURRent [:LEVel] {}[:LEVel]?

The crossover point is reached when the CV indicator goes off and the CC indicator comes on. If you don't care about noise, an 80mm cooling fan in the traditional place on the rear of the PSU may offer better value. 5 Check the number of rails. Disputed Brands (deemed to be of good quality, but needing referenced reviews or articles, or those with disputed quality, or varying quality of different models): ABS/Tagan, BFG Tech, Coolermaster, Coolmax, FSP,

solved I am building a new pc with these specs, how much power supply do i need?

The original monitor PSU (PA-1650-68) was fixed at 19V and 3.32A. However, we'll limit our discussion to the types of electrical power supplies that are predominantly used for test and measurement, maintenance, and product development activities. solved Need help determining if I need a new Power Supply for RX480. Multiple Output Supply Multiple output power supplies have more than one DC output, often two or three.

About this wikiHow How helpful is this? Efficiency is the output power divided by the input power and of course will always be less than 100% (it's usually converted to a percent). Modern lab-quality power supplies should have temperature coefficients of under 0.05% per ˚C. Check This Out Laptop/smartphone power supply will work on either.

Never open a power supply, in spite of information on the internet advising otherwise. Yes No Can you tell us more? Electrical components all have voltages above which they fail. It will help eliminate extra wires to get in the way of cooling.

It is fairly common to put two power supplies in series to get a higher voltage than either can supply. The different AC voltages are generated using a transformer (or an autotransformer). Two of these are called Hot or Lines, and the third is called the Neutral Line; short-form labels are L1 and L2 and N. That sort of clock can likely be done at stock voltage.

They were little more than a transformer, four diodes making a full wave bridge (takes the absolute value of voltage electronically), and the filter cap. What they usually mean is 1) This card need 150 Watt from +12, 2) most 450 Watt PSU can deliver up to 200 Watt on the +12 volt rails, 3) lets Transient response time can be specified and is related to how long it takes the power supply to recover to a specified value after a sudden change in load or output. Certainly, an excellent way is to test it with the actual load it is intended to supply, if that's possible.

Why does Warren Buffett say his fund performance, relatively, is likely to be better in a bear market than in a bull market? Your typical PC desktop power supply will have a little red switch in the back to flip between the two voltages, most nicer power supplies will be automatic switching though. ifartedOct 1, 2012, 2:16 PM thor220 said: Try thisRAIDMAX RX-500AF$44.99 - free shipping10% off w/ promo code PSUSEP12$40.49 after promo codea 500w PSU with good ratings at a great price That These are useful and cost-effective for systems that require multiple voltages.

For example, a 600W supply to ensure 300W of +12V. A variable AC supply is needed for this type of testing. Most modern motherboards require the 24-pin connector, while older motherboards will only use the first 20 pins. The power waveform can be gotten by multiplying the current and voltage waveform using the oscilloscope.

What is the difference between a DVD drive and an HDD power connector? How well does the PSU handle changes in current? Because of this, switching mode power supplies often have a minimum output voltage specification. It is always desirable to have the ratio be as close as 1.
