Choosing the Best Power Supply?

You’ve got to keep the following things in your mind before you buy a power supply unit for computer.

Power Draw & Efficiency

This is a basic test that can help you understand which power supply would fit with your PC. You need to first check how much power draw your PC is doing under load. For that, using Cooler Master’s online calculator would be the right choice. It’s easy to use, effective and gives good estimates.

After finding that out, you need to consider the efficiency of the power supply as 80Plus . Here is a neat chart you can take help from.

This chart is essential to understand when choosing PC PSUs as they tell you how much margin you have before you’re pushing your supply to the limit.

Suppose your PC estimated power draw is 400W, for example (let’s say it’s 430 watts for good measures), and you go for a 500W Bronze power supply. In that case, it will basically be right around the edge under full load. Under that kind of stress, it won’t last very long.

This means a bronze rated 500-Watt PSU at 100% load will give you an effective 410 watts of power. But at this point, it will be screaming for mercy. You need to understand and calculate efficiencies and power draw as well before choosing a power supply.

It is also good to buy a power supply above your rated system draw to leave room for improvements later. Plus, running your power supply at 100% or close to 100% isn’t recommended at all.

Quality vs Budget

Some people believe that High-quality PSUs are magical and can never fail on you, whereas budget power supplies. Well, think again.

It’s not about the price of the CPU that defines its efficiency; it’s the components used. In fact, you will come across certain PSUs with the same wattage, but one will perform better than the other.

While yes, the general guiding principle is that the more expensive, the better in terms of PSUs, but it isn’t the case 100% of the time.

You must also consider that sometimes similar priced are listed in different tiers of power supply units. So, going for the only price isn’t always the best rule when buying power supplies.

SLI / CrossFire

While there are only a tiny number of people who actually do Crossfire / SLI GPUS together, it is still something that many people consider.

If you have a VEGA 64 / 56 crossfire setup, then getting a power supply unit rated at least gold and 850 Watts to 1000 Watts is recommended or higher (considering the rest of your system specs). This is because these graphics cards have a relatively higher power draw.

For current-gen Nvidia graphics cards (the GTX 1000) series, you could get away with SLI 1080tis at 750 Watt to 850-watt gold-rated or better power supplies (depending on the rest of your system). The best rule is to use the Cooler master calculator mentioned above to ensure the power draw is within your PSUs capabilities.

You may also need to consider the 12V rail amp for the PSU and the load regulation along with it.

Modularity

This is a personal preference; most people prefer getting modular PSUs mainly because they’re more accessible to manage. And getting custom length (and color) is a thing that ties together the rest of the build.

Non-modular PSUs aren’t less quality than their counterparts but are more focused on closed case builds (no windows) and manufacturer-built systems. While getting a non-modular PSU doesn’t mean you made a wrong choice, it does restrict you from managing cables and all that mentioned above.

However, if you want the best of both worlds, getting a semi-modular powers supply is a sound choice. It comes with the price advantages over a modular power supply while providing most of the functionality. Plus, you can customize it with different length cables and custom colored ones as well.

Connectors

It is essential to consider that the PSU you are going to buy can connect each system component. If not, then it is useless to go with. There are several vital connectors that you always should prioritize. The first is the main connector that connects the power supply unit to a motherboard. The said connector comes in two types: a 20-pin connector and a 24-pin connector. The latter 24-pin connector is getting popular in most of the latest systems.

Next is the Processor power connector; this connector connects the power supply unit to the processor. Processor power connectors are of two different types, 4-pin and 8-pin versions. Look for one that is compatible with your system. Usually, a 4-pin Molex connector is used to connect optical drives, Hard disk drives, and other devices.

Best PSU 2023

1. Corsair AX1600i

Powerful 1600 watt PSU

It’s the best power supply for gaming that supports ATX and will give you all your power needs. And not a single game will be left beyond where you may need some more power.

Pretty evident that the power supply of this wattage will come with a considerable price, but the price won’t matter if you really want some good power. It never degrades and will constantly be giving you the energy your PC needs.

Previously EVGA 1600 T2 was the best 1600 watt power supply and still is a good option. Still, it is analog, whereas the Corsair AX1600i is digital, and as per several tests and experiments, it performs better.

Rated as 80+ Titanium in terms of efficiency, there is nothing beyond that. Of course, suppose we switch to Cybenetics’ ETA efficiency standards. In that case, it does not reach the ETA A++ standard but is rated at ETA A+.

One of the factors that makes it best is the quality of components. Under the hood, this 1600w PSU has 105°C Japanese capacitors. Also, they’ve switched from silicon to gallium which decreases the losses in switching and brings in more efficiency.

Besides, using the CORSAIR LINK software, you can adjust the power settings and obtain what you need. The software lets you monitor and control several things.

Corsair AX1600i is a fully modular power supply, and you can also choose what color you want. In addition, the “Zero RPM Fan Mode” is amazing and dead silent when operated at low or medium load.

• OVP (Overvoltage protection)
• UVP (Under voltage protection)
• OPP (Over Power protection)
• SCP (Short Circuit protection)
• OCP (Over Current protection)
• ICP (Inrush Current protection)
• SP (Surge protection)

You may face some noise when operated at a high load. But because it works at 1600w and gives you above 94% of efficiency, the noise is not a big deal. Overall, if you really need and want to buy a 1600w PSU, don’t look here and there for more suggestions. This one is the best you can get with all the features and a warranty of 10 years.

You will almost get all the same features in PSU’s from different companies. Still, Corsair is durable with an impressive 10 years warranty and their state of the art customer service. Sometimes these things save your back.

Adding a 1200 watt power supply in this guide is that sometimes people want to get a high wattage power supply although they don’t need it. In that case, you can always choose a 1200 watt power supply instead of going to 1500w or 1600w, which are very costly.

The HX1200 is 80+ Platinum rated, which means it is highly efficient, giving above 90% efficiency.

It does not have a digital circuitry for using the monitoring software by Corsair. Sometimes people just don’t want the monitoring stuff because connecting an extra cable to the motherboard is messy and hectic. This also makes it a few bucks cheaper than other variants which have the monitoring functionality.

This Corsair power supply unit is fully modular, comes with a range of connectors and cables and is dead silent when there is no high load.

Finally, under the hood, it has Japanese capacitors that don’t degrade so easily.

Frequently Asked Questions

What is 80+ Rating Certification?

80+ is a certification program which tells us if a power supply is 80% efficient under 20%, 50% and 100% loads. Power supplies from brands who claim to have passed the 80+ test are actually tested in independent labs. Th levels in this rating mechanism are, 80 plus, 80 plus bronze, 80 plus silver, 80 plus gold, 80 plus platinum and 80 plus titanium. If you do not understand and get confused in all this, just make sure that the PSU you buy is 80+ certified and is higher up among these mentioned levels.

How many watts do I need on my PSU?

There is no single answer to this. Every system is different, and each hardware component of a PC has its own recommended minimum wattage. When calculating the required power supply for your PC, the best thing to do is to find an online PSU wattage calculator and determine how many watts you need. Then add another 100 extra watts to the final value. This way, you always have more wattage than necessary for the system, and you are always on the safe side.

What are power supply safety and protection mechanisms?

Power supply in your PC deals with current and delivering power to all your components. This makes it a risky component because any issues will directly affect all other components connected to it. Therefore, to stay on the safe side, make sure the PSU you buy has all or most of the listed safety and protection mechanisms.
