Game Deal Buyer’s Guide Questions
What is a gaming power supply?
A power supply, or PSU for short, is an essential part of your gaming PC. You would also have heard of it as a converter or power supply. A power supply is generally a hardware tool or device that takes energy from the power source and then transforms it into operational energy for use by your gaming PC.
Many parts inside the gaming PC run on power supplied by the power supply. The device generally transforms alternating current (AC) into an uninterrupted and constant power called direct current (DC), which is generally required by the gaming PC for the smooth running of an action.
The power supply also regulates the voltage, which helps prevent the PC from overheating. The voltage is automatically adjusted according to the fluctuation of the main power supply. Without the use of a power supply, these fluctuations can end up frying your PC completely. It therefore cannot be taken lightly. It would be a great gift for any gamer.
Can the power supply affect performance?
A power supply unit is critically important in a gaming PC. It doesn’t really affect performance in a positive way, but if your power supply isn’t powerful enough to run your system properly, it can leave a very negative effect on your system.
A power supply with less wattage than needed simply won’t work for the entire system in the first place. And even if by some miracle it works, it would put your system at huge risk. Your graphics cards won’t work on it, and if you try to do so, you risk damaging them. Likewise, it will not be able to handle a graphically heavy application.
On the other hand, having a power supply of more power than needed, though, shows no performance benefit. But it has its advantages which ultimately lead to great overall gaming performance. Hold on, look.
To keep your gaming PC and the whole system intact and working for a long time, you need to have a power supply. The power supply provides your PC with constant power that keeps it running smoothly and therefore will make your gaming experience more fun and enhanced.
Since a power supply provides the required amount of continuous power to your system, it automatically protects it from any kind of damage. For example, if you are using very high quality graphics cards that require very high power, your application will be damaged if your cards do not receive the required power.
Advanced level players know very well that their electricity bills can easily increase due to their power-hungry equipment. In such cases, an 80 Plus certified power supply helps a lot in reducing the amount of energy that is usually lost due to all the heating. So if you want to keep playing without getting those crazy electricity bills, you know what you need.
If you decide to go for a model that is slightly more advanced than your requirement, it can turn out to be a very worthwhile investment for the future. Over time, everyone keeps improving their gaming gear to keep up with the latest. An equipment upgrade would also require an upgrade of the power supply unit for obvious reasons.
But if you’ve already invested in a modern, larger power supply unit, you’ll have no problem upgrading your system.
What type of power supply is needed for games?
The type of power supply you need depends entirely on your own installation and system. Several factors play a key role in this regard. The following points will lead you to the type of system you need.
For obvious reasons, one of the most important factors to consider when choosing a power supply is its power. The wattage or wattage of the power supply is usually marked on the box itself. To choose the right amount of power, you must first determine the highest amount of power your system needs.
Don’t worry, it’s not like you have to do it manually on your own. There are many power supply calculators online that you can rely on.
Once you have calculated the total power required by your PC, you will have a clearer idea of which power supply unit you should choose. However, it should be borne in mind that it is always necessary to keep a certain margin of maneuver to choose its power supply, for example approximately 20 to 25%.
This means that if, according to the calculations, your PC needs 400 watts of power, you should at least get a 500-550 watt power supply. More is better, but make sure you don’t get exactly the same power as you got in your calculations.
Not that it will have much of an impact on your current games, but it’s a way to insure yourself for the future. As if, in a few months, if you decide to run your processor or graphics card, they will end up increasing the total electricity consumption. Therefore, you should always keep some leeway for any such future possibility.
One thing to keep in mind is that, contrary to popular belief, the wattage listed on the power supply is not necessarily drawn from your power source in the same proportion. The number on the box basically indicates the maximum power it can deliver.
This means that if you purchased a 1000 watt power supply, it will not sustainably draw 1000 watts from your power source. Rather, it means that it can provide a maximum limit of 1000 watts whenever needed. And in general, these PCs do not need such power for long periods of time.
So, given everything we just said, there are two things you need to keep in mind when digging into the PSU. And those two things are constant power and maximum power. As mentioned above, the wattage listed on the power supplies is the highest wattage they can draw.
On the other hand, constant power is the average power you can get from a power supply at an almost constant rate. And this power is usually not listed on your power supply. Always keep in mind that a power supply unit doesn’t just peak for no reason. This happens quite rarely, even if you use very powerful games or applications.
In general, a power supply of 550-600 watts is enough for anyone who uses a single graphics card with multiple storage devices. However, if you plan to use multiple graphics cards, you should get a power supply with a maximum power of at least 1000 watts. Finally, for those of you who use power-intensive gear, a 1200-1600 watt PSU would suffice your needs.
Always keep in mind that higher power does not mean better performance. It makes no sense to get a 1200 watt power supply if your entire setup only requires 550 watts at most. Therefore, do not try to keep an excessive margin by choosing a model with twice the power you need. Just make sure what you’ve selected is enough to support all your gear and that’s it.
Many of you make the same mistake of only paying attention to power and ignoring the rails altogether. Surely that’s not how it should be. However, it is true that the maximum power indicated on the power supply gives us a fair and precise idea of the maximum number of watts that we can draw from it. But your PSU rails also have a lot to do with getting maximum power.
For those of you unfamiliar with the term, a voltage rail is actually a solitary voltage delivered by the PSU. On these power supplies, you are going to see 3 main voltage rails which include 3.3V, 5V and 12V rails. The last one, i.e. the 12V one, is very important as it has the power to run all the key components of your gaming gear.
You can simply check the rails by looking at the full PSU spec list where all the rails are listed in amps. During your pursuit, you will also come across power supplies with one or more voltage rails. But this is not at all something that should puzzle you, especially in modern power supply units, as it is quite common.
All you need to keep in mind is that the voltage rails of the PSU you choose should be adequate enough, in fact, a little more than adequate, to run your system smoothly. .
You may have seen this term “80 plus” mentioned more than once on the containers of power supply units. And with those 80 plus you would have seen other kinds of different terminologies like 80 plus bronze or platinum or gold etc. So what does this certification mean? If you don’t know, it just indicates the efficiency level of the PSU.
A few years ago, companies were not in the habit of testing PSUs to check their level of efficiency. However, a few companies have started verifying that the power supplies they send out for sale are safe and compatible enough to be used by all kinds of computer systems. This is how the 80 plus certification was introduced.
But it doesn’t really say how and on what basis some power supplies get this certification. And how exactly is the level of efficiency tested? Don’t worry, we’ll explain all that to you as well. To start with, companies use different loading percentages to check the efficiency of the PSU.
You should keep in mind that the efficiency of the UPE does not stay the same throughout the day and fluctuates depending on the load. Now, to receive 80 Plus certification, the PSU, at its highest wattage, must show 80% efficiency at 20%, 50%, and 100% load.
As for the name of the metal in this term, it simply indicates the degree of efficiency of the PSU at the given loads. For example, the 80 Plus Gold Certified PSU will be 87% efficient at the minimum and at the highest load.
Now, if you are wondering how does this help or concern you? So, let’s clear that up too. In other words, an efficient power supply will save you money on your electricity bill. The amount saved would not be very high, but that is how you save, a little here and a little there.
Plus, by opting for the 80 Plus certified power supply, you ensure that your system will always receive the amount of energy it needs to operate. Therefore, whatever you do, don’t skip this important feature when selecting your PSU.
Modularity is another term you might have come across while researching power supply units, but not all of you know what it means. It doesn’t matter, because we are here to take care of it! Ok, so when it comes to modularity there are usually two terms that you will see on the packaging of power supplies, fully modular power supply and semi-modular power supply.
Basically, the modularity of the power supply unit can be divided into 3 different types: fully modular power supply, semi-modular power supply and non-modular power supply. In a non-modular power supply unit, all wires and cables are directly connected to the unit. This means that all wires are irremovable. This type of power supply can be quite inconvenient for people due to the heavy need for wire management.
In a semi-modular power supply, all essential wires are directly attached to the unit, just like in the non-modular version. But, apart from the essential cables, the optional cables are easily removable. This makes it quite convenient to use as you don’t have to deal with cables that aren’t even used.
Surely you would have had a fairly fair idea of fully modular PSUs by now, but let’s explain that too, just in case. Fully modular power supplies are not equipped with integrated cables, which explains their complete modularity.
These PSUs are relatively more expensive compared to the other two versions. But, that’s understandable given the level of flexibility they give you. You can actually remove every cable from these power supplies. This means you don’t have to hang on to a single extra cable that isn’t in use at the moment.
The PSU is not something you can buy just anywhere or from some obscure manufacturer. It’s something your whole PC is going to depend on, so make sure you get it from a reputable and esteemed manufacturer. And it’s not an option, it’s simply a MUST.
Buying it from a reputable manufacturer ensures that the product is reliable. Second, and very importantly, a power supply from a famous brand will also come with truly amazing warranties and outstanding customer support. In general, these PSUs come with a minimum guarantee of 3 years. And it may be higher with different models and manufacturers.
Unlike before, power supplies these days are very sturdy in construction and highly durable. If you think back a few years, you will remember when it was considered very risky to have a power supply unit for your system. Back then, UPEs could not only fry your system, but also your house.
But fortunately, with the arrival of special protection technologies in power supply units by reputable companies, these dangers have completely diminished. These special guard mechanisms ensure that the unit only delivers power within the above limits. Good companies implement special protection instruments to protect your PC against overloads, overcurrents and high temperatures.
In contrast, a cheap power supply from an unknown brand will have none of these features. So, if you don’t want to set your PC or house on fire, stay away from these. Another thing to keep in mind is that you don’t necessarily have to choose a PSU with much more power than you need. Just make sure it’s suitable enough for your system while still having a slight margin.
What power do you need to play?
The importance of a power supply for your gaming PC cannot be overemphasized. And that too of very good quality, as inferior products will not be able to support the load well and will impose a load useless to the system. And in extreme cases, they can even completely destroy your valuable hardware.
As we also mentioned above, to determine the amount of power needed for gaming, you can simply use online power supply calculators. But as we also pointed out earlier, it’s not enough to just go for a PSU that has exactly the same power as your PC needs. You need to keep extra space to be safe so that it can be useful in the future as well.
Now, the way to calculate horsepower using these calculators is quite simple, so don’t feel intimidated at all. You don’t have to do anything manually. These calculators will ask you everything you want to know about your system, graphics cards, and connected devices. You just need to read the question and select the option that is applicable to you and that’s it.
In general, if you’re going to build a single GPU, you can use a PSU rated at least 600 watts. And for a slightly more capable system, the ideal power supply should have an output of 650-700 watts. Second, for SLI dual gears, a minimum of 750 watts is sufficient. This means that you should not go below 750 and anything above that number would be fine.
The minimum power requirement also largely depends on the additional devices you are going to add to the PC. So, remember that we are giving you an idea just so that you can see it with your own eyes. This does not in any way mean that the figures we have given would work correctly for all of you. So you have to calculate it yourself depending on your platform.
If you’ve made such purchases before and used dual SLI gear before, you’ll probably have a better idea of what you’ll need. And for those of you, this will be your first time, you should stick to calculators.
What other components are needed for the power supply?
The other major components needed to get the power supply unit up and running are as follows:
Without the above components, the power supply unit will not be able to operate. If you want to learn more about maintaining your PSU and rig, check out https://www.reddit.com/r/buildapc/comments/1yg8xg/dos_donts_and_tips_for_first_time_bulders/.
