Gaming computer power supply calculator

Power consumption of your computer is measured is Wattage or Watts W , which is a unit of power. All the power supplies available in the market have their own maximum power capacity load carrying capacity or wattage associated with them e. The more is their wattage, the higher the load they can bear or can provide the rated power to your computer components.

Wattage or Watt W is one of the most important factors for choosing the power supply because at the end of the day it really comes down to the fact that Is you PSU capable of handling your computer load comfortably or not. On the other hand, if you have chosen a much higher wattage PSU then you would be wasting much of your money on it, which you could have saved and invested in some other components. So, choosing a proper wattage PSU is a wise decision and here I am going to list down some of the best power supply calculator tools that will help you predict your computer power consumption in wattage so that you can buy the right Wattage PSU for it.

You just have to select the right components that are installed in your computer and then press the calculate button to know the approximate power consumption of your desktop PC. Here are the best online power supply calculator tools that can help you to choose the right wattage PSU for your PC whether it is a gaming or a workstation one.

These power supply calculators are updated regularly with new hardware components and are pretty accurate in predicting your PC Wattage and Power Supply Recommendation. To use these PSU Calculators, just select the components that you have installed in your PC case and then hit the calculate button to know your power supply requirements. This is a very accurate power supply calculator and it comes with more options and features than other power supply wattage calculators.

It has got two modes of operation for calculating power consumption, basic and expert. The basic mode or version allows you to select minimum sets of components major parts to estimate the total power consumption while the expert version allows you to choose various PC parts or components USB, LED, Controllers, Liquid Cooling etc. The only real drawback in this unit is the pair of EPS connectors hosted on the same cable. Usually, EPS connectors should be installed on dedicated cables for lower voltage drops and enhanced safety, but the platform didn't provide enough sockets for this.

The Corsair AXi was the first desktop PSU to use its cutting-edge power supply technology, but even several years after its initial release, few other PSUs utilize it. Okay, those are the technical details, but what you really need to know is that this is about as efficient as power supplies get.

The AXi is the worthy successor of the legendary AXi. Both units are made by Flextronics, using cutting-edge technology while offering the best performance that money can buy today, thanks to their digital platform. Besides being highly efficient, the AXi also offers outstanding load regulation, excellent transient response, long hold-up time, and excellent ripple suppression.

Despite its high capacity, it remains impressively quiet in operation, thanks to the relaxed fan profile and a high-quality FDB fan. You will pay a lot to get your hands on a Corsair AXi, but there is nothing else able to meet this PSU eye-to-eye when it comes to overall performance. If PC building isn't part of your skillset, look at our guides for the best gaming PCs and best gaming laptops that can give you the most bang for your buck and save you a headache.

More and more of the best power supply brands have expanded into the small form factor category recently, an area that has started to garner much greater interest from gamers too. A few years ago, SFF PSUs were niche products, but the introduction of elegant small chassis, and the desire for smaller systems, have increased the competition in this category. Fractal, meanwhile, had nothing to show in this category until it launched these SFX Gold units.

That means they can have more relaxed fan speed profiles and be quieter than their standard SFX counterparts. On top of that, the larger PCBs allow for higher capacity units, too, up to W. The Ion SFX G advantages over its Corsair SFX adversary are the larger, mm fan because it follows the SFX-L format, along with the highly flexible modular cables, which indeed make a difference during the cable routing and installation processes.

Besides the experience and vast knowledge of electronics, the evaluation of power supplies also requires insanely expensive equipment , which not everyone can get their hands on. On top of that, even if you have the proper equipment, you need to know how to operate it, and above all, you have to properly maintain it AKA calibrate it in frequent intervals to ensure that your results are correct.

The recommendations that we list in this article are based on data that we gathered using the equipment shown below:. We use top-of-the-line equipment to test power supplies, including Chroma electronic loads, Keysight AC sources, N4L power meters, Keysight and Picoscope oscilloscopes for PSU timing, and ripple measurements, along with other specialized equipment.

When it comes to noise measurements, besides a highly accurate sound analyzer, we also have a hemi-anechoic chamber at our disposal, with a close to 6dBA noise floor. The noise measurement's set-up is depicted in the photos below. You don't need a degree in rocket science to work out the wattage requirements for your system.

The recommended system power requirement listed on the specs list for your current or future graphics card is a great place to start. Still, we recommend using an online power calculator to get the most accurate figure.

OuterVision's Power Supply Calculator is our go-to. Once you've found out the wattage you'll need for your PC, you'll need to decide what efficiency you can afford. Power supply manufacturers all tend to agree to the same PSU efficiency rating system: 80 Plus. An 80 Plus Titanium certified power supply is more efficient than a Bronze one, meaning the parts within waste less power heat during the AC to DC conversion.

USB 3. Yes No. Your preferences Silence. Filters Filters Your maximum wattage requirement. Price range. Form factor. Cable management. No matching power supply available, please check your configuration. As some power supplies are not equipped with enough connectors for all PC components in your configuration, you will not find them in the results. Only power supplies with matching specifications will be recommended.

The selected GPU generates high peaks of electric load. This is a critical component of your calculations because almost everything within your build plugs into and derives power from the motherboard. So make sure your PSU has enough cable to support that. Most PSUs will have at least one cable that is compatible with either an 8-pin or a 6-pin connector. Memory RAM — Always know the number of memory sticks that your motherboard can support as well as the size GB of each one.

Optical Drive — If your PC build includes an optical drive, be sure to include this in your calculations. Solid State Drive SSD — You need to know the size GB of each solid state drive that you currently have within your build or that you would like to include. Remember that sometimes these can be attached to the motherboard.
