Considerations for Choosing a Good But Cheap Power Supply
Before you start your search, you’ll want to go through the process of working out which capacities of functioning you’ll need from your PSU in order to ensure it deals with a range of scenarios without a problem. Our readers will know that we’re thorough in helping you decide on favorites from the top suppliers, so without further ado; here are the factors to look for in budget gaming power supplies.
Watts the Matter?
Before you choose the best value PSU, you’ll need to figure out how much power your PC requires. There’s a few different ways to do this, but our top two are:
- Find power draw benchmarks from existing websites for your GPU and CPU, and add them together to give a minimum wattage rating.
- Use a power supply calculator, accessible online through sites like Thermaltake.
The second method is maybe a little easier and more convenient. Best brands such as Cooler Master or Thermal take will generally offer a power calculator on their website. Another key point is that you could probably go higher than the calculated output if you can afford to spend some extra bucks. It’ll most likely give your machine a longer lifespan.
If you only need 280W, there’s no wrong in going a step further and not just going for 300W, but maybe even a 400W PSU . A cheap 400W or cheap 500W PSU isn’t hard to find, so whichever wattage you need you’ll be able to find something for you.
In addition, when you’re thinking about wattage you’ll want to consider the type of wattage offered, comparing this against your requirements.
Continuous Wattage and Peak Wattage are ratings that are based on manufacture tests.
Continuous Wattage indicates that in can deliver its listed wattage, you guessed it, continually – without fluctuations.
Peak Wattage, however, indicates that its listed wattage is the maximum it can deliver, but before it swiftly drops down.
In layman’s terms, it’s best to look for a CW rating and ignore a PW rating. You might also be wary of products that don’t advertise continuous wattage.
A final thing to note is that a higher wattage doesn’t always mean it’s a high-end or high quality product. Many manufacturers will list wattage ratings to be higher than the prolonged deliverance, and whilst the low price may attract you – don’t make the mistake of buying a cheaper model that means your PSU’s less reliable.
Save Time, Save Energy
Whether you’re just really socially responsible or want to cut down on cash spent on bills, you may be after an energy efficient PSU. By the title, we mean to find a PSU that is energy efficient and overall has a high efficacy in functioning.
This, in turn, will make your search more efficient and time-saving by thinking about what you actually need.
Your PSU will be taking power from the nearest outlet and converting it to DC power, but this conversion can be wasteful. An efficiency rating of your PSU therefore refers to how much or little energy is wasted in conversion.
An 80% rating means that only 20% of power is lost in converting to DC. 60% signifies 40% is lost, and so on. A higher efficiency therefore requires less power from your outlet.
It’s also worth noting that higher-efficiency units tend to give you better components and build quality overall. This means that they’ll give a better, high quality PC power supply with a greater overall performance for the price point. This will include a lower production of heat. Your best bet when searching for an efficient power supply would be an 80 plus gold PSU, which means it gives the best efficiency and generally a higher capacity for the cost compared to other market rivals.
Size Matters: Physical Size and Robustness
It’s important to consider the robustness of your PSU unit to consider the overall reliability. This could include preferences of cables and other components, and how this links to performance with your chosen computer build.
There are many budget options for a power supply unit, but sorting the low from high quality design options will depend upon factors and features such as physical size.
For most computer users, standard power supplies of ATX version should be fine, but you’ll still want to ensure that your PSU fits in your case by checking the appropriate clearances. If you’re a small form factor (SFF) fan, you might want to do a little more research for a version that suits your size preferences.
Another feature of robustness to watch out for in your PSU is the version of modularity- i.e. whether it’s fully modular or non-modular.
Fully modular power supply models do not come with cables attached. This will affect installation and requires that you’ll have to connect each cable to your PSU and the powered component, but this also suggests you can optimize for fewer cables and achieve a clean airflow.
Fully modular is good for:
- A cleaner build
- A potentially better airflow
- A little more practicality
Non-modular power supplies have cables already soldered to the circuit board, meaning you can’t modify which cables are in your build. All cables, even ones you don’t use, need to be stored in your case. Non-modular PSUs:
- Are not, functionally, any worse than fully modular
- Can lead to less efficient airflow if cable management is poor
- Allows for less choice
The Fine Print
Like any other technology, with a decent power supply you can easily geek out and get specific about your needs. However, if you’re a beginner, there’s lots of technical jargon that you might be less interested in.
To find the best power supply PC models could benefit from, you can pay attention to pretty much everything this list, while safely ignoring the following aspects. However, seasoned pros might want to read these features to find the best budget power supply with all the best high performance features:
Voltage stability – this refers to a PSU’s ability to keep supplying 12V power without dropping.
Rails- you can get PSUs that are multi or single rail, and whilst both have their pros and cons, the best PSU as high performance really doesn’t need this considered. However, if you’re living somewhere where power outages are the norm, definitely consider a multi-rail model of power supplies.
Cables- We touched on this earlier, as it essentially refers to modular versus not modular High-end PSUs are more likely to provide fully modular cables due to their increased ease, but for a beginner, this isn’t wildly important.
AT vs ATX- this refers to the type of motherboard, as some PSUs are made specifically for one motherboard or the other. Chances are you’re using a standard ATX, however you might want to check just in case. It’s no use buying one of the best PSU models if it isn’t compatible with your PC.
Repair Accessories – in short, you really don’t need a wattage tester or a repair guide. If you’ve found an issue with your PSU, whether it’s a 10-year gap since purchasing or a 5-year gap, you’ll need to replace it. Thankfully, lots of companies offer a warranty 5 year or 10 years long, so with a 10 year warranty you’re more than covered.
Best Brand Reliability
New power supply types are introduced by the best brands at a very quick rate, so it’s actually quite simple to scope out which brands have the highest reviews, make the greatest power supplies, and – if you’re concerned about budget – offer a value purchase for the money, at the cheapest prices.
While budget is definitely important, and you’ll want to find a model that comes with a low enough cost, a high-end unit might be worth investing in because the functioning of the best PSU, whether fully modular or otherwise, affects every part of your PC’s system, at the end of the day.
Trusted brands will offer you choice and reassurance with your purchase, meaning people can get the greatest component they’re looking for with peace of mind. This includes energy/heat efficiency, as most makes will be certified 80 plus bronze, 80 plus gold, or 80 plus platinum for their high performance wattage.
Customer Knows Best- The Importance of Reviews
Another key feature of any search is to check the reviews. There’s no aspect more important than looking between customer review websites and Amazon alike, to see what people have said about the product itself and the manufacturer’s customer support policies.
It’s hard to find reviews on power supplies that are easy to read, easier to trust, and give you all of the information you need – because it’s quite hard to test power supplies.
However, you’ll be able to find a handful of trusted reviews before you dive right in and think you’ve found the best power supply for you. In order to have your pick of the greatest budget power supplies, you’ll need to see if reviews tell you about:
- Customer service
- Warranty policies
- Delivery time and conditions
- Size and efficiency- but keep in mind what PC the reviewer has!
How important are power supplies to overall functioning?
If you’re stuck for how a power supply unit even works, you’ll want to listen up here. It’s important to know exactly what these units are doing in your computer case, in order to see how important these supplies are to overall functioning.
This could affect your decision in terms of warranty – 3 years might not be adequate for you if you have long-term concerns about your supply’s function, but a warranty 10-years long is more ideal.
Looking at which providers offer the best warranty policies isn’t the worst idea, because this will also give you a really good idea of what their customer service and tech support is like.
As you may have known, a power supply unit, or PSU, works by converting AC mains electricity to low-voltage DC power, in order to power the inside of your computer.
Many hail the PSU as an ‘unrecognised champion’ of easy and smooth operation within your PC. Essentially, a PSU is quite important because it allows all of the components of your PC to work to their fullest potential.
A PSU is important for the ordinary PC for a range of different purposes. If your power supply isn’t good enough for the sorts of capacities your PC deals with, this can cause system instability and lead to driver errors. It can also cause hardware malfunctions and reboots – so it’s best to make sure that the power supply you buy works well with your devices.
As we say, it’s all in the warranty – 10 year warranties offer you far more protection than those that last 5 years, so this is definitely something to consider too.
How can I be sure that my power supply is equipped for a gaming PC?
If you carefully consider the needs of your PC and what you’re actually going to be doing with it, then careful consideration will pay off in the long run. A cleaner PSU will keep your components running on clean, effective power at all hours of the day. This is likely to increase the durability of your PC- so if you want to be with your tech for life, a PSU is a worthy upgrade.
Ensuring that your PSU is compatible with your PC, and fully equipped for one, can be difficult. When you consider elements such as a graphics card, makes such as the Seasonic Prime seem like quite a good option.
You’ll want to take care to look at our considerations below to ensure that your needs and wants, when it comes to a PSU or any other component, align with the expectations of your gaming PC. This could include the amount of connectors, the sound, size, and functioning of the fan, or – most importantly – the wattage.
Our favorite makers of PSUs for PC gamers include:
- Corsair RM850X
- FSP Dagger 500W
- Gamdias Astrape P1-750G
- NZXT E850
Of course, those we’ve listed are the absolute best and most suitable for those looking towards a multi-purpose PSU on any sort of budget, but these four listed here are recommended by some of the best pros when it comes to PC gaming.
What is a decent power supply?
A decent power supply will incorporate many different features, making the best choice for your PC in terms of functionality and efficiency.
Any solid pick for the best budget power supply will include:
- High energy efficiency – an 80 plus gold rating is ideal, whilst 80 plus platinum or 80 plus bronze are also acceptable.
- A decent price tag – one of the best will for sure offer the best power it can do for the price. You’ll want to weigh up the benefits of a more expensive high quality power supply, and try to find these features in a cheaper, less high-end model.
- The amount of power – you may be wondering “how much power do I need?” It’s entirely important to get a decent wattage on your power supplies, and our handy considerations above will show you how to get the best PSU for your needs.
- Good customer service- including a convenient warranty, such as a 10 year warranty, 5 years at least.
Follow the links on our site above to find the best power supplies for you, with the best overall performance and high efficiency levels. We recommend the GAMEMAX 650W power supply.
What is the best 1000w power supply?
There are lots of different 1000W power supplies you can opt for, from those with an 80 plus gold rating to an 80 plus bronze rating. These 80 plus certification makes will provide a high performance for any gaming PC. However, what’s the best 1000W model?
We personally recommend the EVGA 1000W 80 Plus Certification power supplies, which offer high efficiency levels for any gaming PC with 1000 watt power and semi modular cabling.
Will a 500 watt power supply be enough?
If you want plenty of gaming power and serious high efficiency in your overall performance, a 500 watt power supply is absolutely fine for pretty much every typical build’s overall performance.
It’s important to note that there are a combination of features to consider before you opt for a certain watt power supply, such as what the power efficiency is like, i.e. whether or not there’s an 80 plus certification, or whether you’ve got enough stability for your gaming PC.
That said, our favorite 500W power supplies can be found with the Seasonic 80 Plus Bronze Power Supplies, which come with a handy five year warranty.
What is a good power supply for gaming?
The best power supplies for gaming will incorporate a range of features, such as under voltage protection features, over voltage protection features, a decent warranty policy, and compatibility with graphics card models used in the greatest PC gaming. It’s important that your power supply cooperates with different PC components, whilst also providing a decent form factor that will correspond to the fan size of gaming PCs.
Our best power supply for gaming, we think, is the Apevia 80 Plus Certification 600 watt power supply, perfect for all of your gaming needs.
