PSU tier list spreadsheet

A PSU [Power Supply Unit] is a bit like that kid no one notices in the class. You dont know where shes from, where she lives, what she does in the class nothin. A PSU, much like that kid, is ignored always.But if youre building a mean gaming rig for yourself and just search casually for PSUs online, youll see that there are literally thousands of models for sale and theyre made by hundreds of companies.

This begs a seemingly simple question: Which one should you buy? Are they all the same or is there actually any difference between these PSUs? What is the best PSU for gaming? [I know I said only one question, but indulge me]. So, we at Game Gavel have created a list. Its a simple PSU tier list written in decreasing order of their performance. Prices have been taken into consideration, as well.

However, before we get into the nitty-gritty of PSUs and their hierarchy, lets take a look at what exactly PSUs do and how they work.

PSU [Power Supply Unit]

Most people whove been around computers would have seen the PSU. Its the unit at the back of the CPU to which you plug the power cable. But if you havent, just take a look at the top-right corner of your CPU [No, no do it now].

The PSU, in essence, converts Alternating Current [AC] to Direct Current [DC]. The electricity that flows from the socket of your home is AC. However, computer components need DC to function normally. Ergo PSU.In addition, the PSU also regulates overheating of components. It does this by controlling the voltage. A change in voltage might happen automatically or manually.

Most PSUs are housed within the CPU casing itself. However, some enthusiasts like to use an external PSU. The advantage is that they are smaller in size and more pretty to look at. However, the number of people who do this is quite small. Therefore, for the purposes of this article, well be restricting ourselves to internal PSUs.

It is always recommended to plug your PSU to an uninterruptable power source [UPS]. The reasoning is that PSUs are the most exposed components to power spikes, surges, and things like that. A UPS will keep your PSU safe.

Choosing a PSU: A Quick Buying Guide

Veteran builders know where to look and what to buy. They have experience on their side. However, if youre new to building rigs, welcome to the PSU quagmire. There are literally hundreds of companies that make PSUs. Whats more, they all look more or less the same.So, which one do you buy?

First off, know that there are many bad companies. So, a shot in the dark more often than not is going to be an expensive mistake.But alls not lost. There are a few reputable, established players in the market. Seasonic, Antec, Corsair, CoolMax, and Ultra make excellent PSUs. However, choosing a PSU from a reputable brand doesnt guarantee performance. There are a few factors to consider.

Factors to consider

If youre set on buying a top-of-the-line gaming processor, you have two companies to choose from. Intel and AMD. Both make excellent gaming processors. However, not every product from their stables will suit your needs. Its the same with PSUs too.

Tip:If youre big on aesthetics for a powerful gaming PC that youre building, we recommend going with a modular power supply over other alternatives.

Always Read Reviews

Between the six or so companies that I mentioned earlier, there are at least 100-150 PSUs on offer today. That being the case, it shouldnt come as a surprise that some of them arent really that great.So, always make sure that you read user reviews of the specific product that youre looking to buy.

Heavier The Better

Lightweight smartphones and laptops are awesome, not lightweight PSUs. The reasoning is quite simple, actually. The PSU houses capacitors, heatsinks, fans, chokes, and much more. All these components work much more efficiently when theyre bigger.

For example, bigger heatsinks enable better heat dissipation. Bigger fans can turn at slower speeds and achieve the same cooling results. Lower speeds mean quieter functioning, and bigger fans can handle more load than smaller ones.

The Wattage Myth

The power, so to say, of a PSU, is rated in terms of watts. This rating in watts is actually the output of the PSU. As the output increases, so does the power of the PSU.Much like a car, you might think. Bigger the engine, the faster it is except thats not how it is, both, in cars and in PSUs.

Lets say that your rig needs about 500W for ideal function. Irrespective of how powerful your PSU is, it only delivers 500W. Just because a PSU is rated at 2000W, it doesnt mean that itll deliver that power.You already know the conclusion. Higher watt rating doesnt necessarily mean that its better.So, how do you pick the ideal one?

Well, most desktop PSUs are rated anywhere between 200 to 2000 Watts. To know the best one, you should first calculate how much power your CPU needs. This number is called the TDP [Total Design Power] of your system. TDP is simply the sum of the power requirements of all the components in your computer. There are plenty of free online calculators to arrive at this figure. Just punch in your components, and itll give you a TDP figure.

For the purposes of this article, lets say the TDP of your system is 500W.A 500W PSU is NOT what you should be looking for. A bit of business 101. Companies want to show off that their PSUs have a high wattage. So, instead of ideal working wattage, they display peak wattage.

PSUs arent capable of performing at their peak levels continuously. Actually, they can only output about half their wattage number for extended periods. They have about 50% to 60% efficiency. From time to time, they can achieve 70% to 80% efficiency.For your system that has a 500 TDP score, what you really need is a PSU with a 1000W rating. So much for our laws on fair and truthful advertising.

Efficiency and 80 PLUS Ratings

Efficient PSUs have better components, dont waste a whole lot of power, they dont get very hot things like this, basically. Theyre good. But thats not the important part.If youve ever looked at a PSU or even if youve seen a PSU listed online, youll see that some of them have something called 80 PLUS rating. This rating is important. There are five ratings overall.

80 PLUS, 80 PLUS Bronze, 80 PLUS Silver, 80 PLUS Gold, 80 PLUS Platinum, and 80 PLUS Titanium. Titanium is the best rating that a PSU can get.The term 80 PLUS basically refers to the fact that the PSU is at least efficient to the tune of 80%.So, what rating should you go for?

Well, Ill tell you this much. I was recently testing a few AMD gaming processors. I had a 16 core processor overclocked to almost 5GHz. I had a water cooler running at a good clip too. All that I needed was an 80 PLUS Silver PSU.Now, overclocking and a water cooler are not the most stressful things for a PSU, but you get the idea.For most people, including gamers, 80 PLUS, and 80 PLUS Bronze are more than enough.

With all this information assimilated, lets get to the table itself. As mentioned earlier, the list places the most powerful PSU at the top and the least powerful one at the bottom. For convenience, Ive created a tier system, which is explained just below the table.

Enthusiast Tier 1

These are the best PSUs on the market. They are made from high-quality components, have a boatload of features, and of course, are very expensive.Is this for you? Nah. Not really. This is for enthusiasts who overclock their i9s, use powerful water coolers, and run multiple top-of-the-line graphics cards simultaneously.If youre a casual user or even a casual gamer, you have no reason to buy these beasts.

Tier 2

Workstation coolers are what youre looking at here. Not just normal workstations, but high-end ones. PSUs in this tier are still quite expensive and again, gamers, even professional ones, dont have much use for these.However, if budget isnt a concern for you, this tier offers some excellent PSUs. Using these will effectively future-proof your PSU. Theres plenty of overhead room if you later decide to add in more components.

Tier 3

Prices decrease, obviously. But these are the PSUs that professional gamers are most likely to use. Veteran builders will vouch for these products. Most of the brands and models in this tier are known to be very good.

However, if youre a new builder, dont go for these. For one, they are still very, very expensive. You dont really realize how expensive they can be until you actually go online and check the prices. If youre new to this world, you dont want to begin your experiments with these PSUs.

Tier 4

This tier is the most popular one for gamers. Prices are low enough for gamers to afford these, and they are super-reliable and long-lasting. The build quality is great, and basically, these PSUs do their job without creating much of a fuss.

Tier 5

If youre a novice, this is the category that Id personally recommend. These puppies have no extra features, they dont look like theyre from the 2100s, but they do their job reasonably well.

The efficiency of these models arent as great as the ones mentioned above, but its not bad either. Prices, though, are significantly lower and for a novice builder, thats important. You dont want to invest too much into something that youre still not very sure about.

Tier 6

The PSUs in this category are budget PSUs, and unfortunately, thats the only upside. Efficiency is quite bad, and so is the build quality and reliability. If youre a gamer, this category just wont cut it for you. Look further up. However, if youre simply building a no-frills, basic PC, you might want to consider these. There are no promises made here.

Tier 7

This is basically a compilation of dont buy devices. Theyre bad, and frankly, they shouldnt be on the market. Avoid and survive.

Conclusion

So, there you go. Thats the hierarchy list complete. Now, we havent even mentioned about 10% of the overall products currently in the market. But, as I mentioned earlier, there are way too many bad manufacturers out there.

The most important thing to look for when youre buying a PSU is a well-known brand. Now, is that a bit judgemental? Yes, it is, but there are so many bad products out there that we, as customers, dont really have any other choice. Better safe than sorry, as they say. If youre not sure whether to replace your power supply, first you need to learn how to test a PSU. If its faulty, ditch it.

Let me know which one you eventually go with. Its always great to hear from you people out there. Also, have I missed your favorite brand or model? Let me know why I should go ahead and include them!
