How to Determine What Power Supply You Need

Building a estimator yourself, or even upgrading i, isn't difficult, but it does crave that you at least have a bones understanding of how all of the pieces go together. To build or upgrade 1, you need to understand what video cards are compatible with your motherboard, what processor socket types are compatible with your motherboard, and arguably nearly importantly, how much power information technology's going to accept to keep all of that running. Afterwards all, if you don't buy the right power supply, your figurer won't stay running at all. With the wrong power supply installed, plough on your PC, and it'll immediately turn off.

So how do you tell what power supply your currently have in your arrangement? If y'all're edifice a PC, how practice y'all tell how much wattage you will need to keep information technology running? Or, if you're upgrading a PC component, do you too need to upgrade the ability supply to business relationship for the added ability draw? These are all questions nosotros'll comprehend below. Let'south swoop correct in!

Determining the Output of Your Electric current Ability Supply

In most cases, to tell what size power supply you have, you'll have to open your PC example. That's ordinarily only a few screws around the back of the arrangement, then a side easily slides off. So, you just need to look and see what wattage your ability supply is. The power supply itself unremarkably tells you with a characterization on 1 of its sides that gives y'all some general specs. Usually y'all'll on the label a column that says MAX LOAD: 500W, or whatever your model of ability supply is capable of. If yous don't run into that, the model number is always on that label, which makes information technology easy to lookup online and find out with a elementary Google search.

If you don't run across the characterization, then it'southward probably on a side of the power supply that isn't visible. All ability supplies have an identification label, as required by UL — formerly referred to as Underwriters Laboratories. That said, to find the label, y'all'll demand to carefully remove the power supply from your system. Earlier proceeding with removing it from your PC, make sure all ability is cut off from the arrangement — you don't even desire it plugged into the wall outlet or power strip. As a prophylactic measure, make certain to turn the power supply to the OFF position, also. This is ordinarily represented with an O icon, either on the back of the instance, or on the ability supply itself inside of the case.

Once you pull the power supply out, you should run into a characterization on the not-visible side. If yous don't, we wouldn't recommend putting that power supply back in your computer — ability supplies without labels are dangerous to use, and is a sign of a low quality component that could potentially fry all of your calculator parts.

Unfortunately, you lot more often than not aren't able to tell what type of power supply you take by fashion of software. This is because most power supplies aren't intelligent, which means you cannot use software to pull up its specs.

Do Y'all Demand to Upgrade the Ability Supply if You Upgrade a Function?

If you upgrade a component on your estimator to something more powerful, you may or may non need a new ability supply. If you already have a ability supply that has fashion more capacity than you already need, y'all're good. However, you'll ever want to brand certain that you're non exceeding your ability supply's recommended output. So, information technology's recommended that you double check how much your power supply'southward maximum load is capable of — just follow the steps higher up — so brand that, say, your video card doesn't put y'all over the top.

That's why, every bit a general rule when building a PC or upgrading a power supply, PSU for brusque, it's recommended to get one that'south 150W to a higher place your demand.

How do I Know How Much Wattage I Need When Buying a Power Supply?

Luckily, there are a scattering of free online tools and an equation that will help you find the wattage that you need.

Using the Equation

The basic equation for calculating the amount of ability, or watts, is P = I x Five. Put just, this equation is Power = Amps ten Voltage. So, the corporeality of watts needed will be equal to the amount amps times the volts of the parts used, i.e. the GPU, HDD/SSD, Optical Drive, etc.

Using an Online Tool to Calculate the Wattage for a Power Supply

Both OuterVision'due south Ability Supply Calculator and PCPartsPicker will help y'all determine the ability supply wattage that you need. The way these work is that you enter in the PC components that you have in your PC — or the PC parts that you plan on buying — and it will then calculate the power describe of all of those components. Then, information technology'll tell y'all how much wattage you need in your ability supply, based on the power depict of those components. As an added bonus, PCPartsPicker is able to testify you if you're building a automobile with all compatible components so you don't purchase the incorrect hardware during your PC build.

Now that you know how much wattage y'all accept to support, you're prepare to go out and buy a new power supply (or stay with your old ane, depending on your results)! Yet, at that place'due south one more matter to keep in listen….
