So you want to know what the best PSU of 2019 is? You also want something that's budget friendly? Then you've come to the right place.
If you're struggling to keep up with some of the technical terms mentioned throughout this post then feel free to skip to our glossary at the bottom.
But enough about that, let's get in our top 5 list.
Best PSUs 2019
|Efficiency Rating||80 PLUS® Gold|
|Connectors||1 x 24-pin ATX, 1 x EPS Connector, 1 x Floppy Connector, 4 x 4-Pin Peripheral Connector, 4 x PCIe Connector, 6 x SATA connector|
Quite simply, the Corsair TX650M is a fantastic semi-modular PSU and suitable for the majority of mid-level PC builds. With it's 80 Plus Gold efficiency rating, you'll never have to worry about having enough power again.
The 120 mm cooling fan provides an adequate amount of thermal control but can get a little bit noisy under load. So if you are going for a ‘silent' or ‘low-noise' PC build then it might be worth grabbing a different PSU from our list.
To give you some serious peace of mind, Corsair also provides you with a 7-year warranty for this PSU. Meaning even if anything goes wrong you'll be covered for quite some time.
Also great for first-time builders, the TX650M comes with clearly-marked connectors which makes installation fast and straightforward.
In summary, the Corsair TX650M is a fantastic low-cost PSU that is perfect for most single GPU builds. Newbie friendly and something that will last for many years to come, especially with the 7-year warranty.
2. EVGA 750 GQ
|Efficiency Rating||80 PLUS® Gold|
|Connectors||1 x 24-pin ATX, 2 x 8-Pin (4+4) EPS (CPU), 6 x 8-Pin (6+2) PCI-E, 9 x SATA, 3 x Four-Pin Peripheral, 2 x Floppy|
Another fantastic entry in our list, the EVGA 750 GQ rocks the largest amount of power output out of all our entries. So if you're looking to build a high-end single GPU system then this might be the budget PSU you are looking for.
Whilst the 135 mm fluid dynamic fan provides an adequate amount of cooling to the PSU, it can get a little bit noisy under load.
It also features a few protective measures that will provide longevity to your PSU such as OVP (Over-Voltage Protection) and SCP (Short Circuit Protection).
Being semi-modular it can help make your PC build a lot more tidy than a non-modular PSU.
Much like the Corsair TX650M, the EVGA 750 GQ provides full power to your PC build even under high ambient temperatures (47 °C).
To summarise, the EVGA 750 GQ is a strong contender in the sub-$100 PSU market. With a high maximum power output, we would recommend this for high-end single GPU PC setups.
|Efficiency Rating||80 PLUS®|
|Connectors||1 x 24-pin ATX, 1 x 8-Pin (4+4) ATX 12V, SATA (4 Pin) x 6, PCI-E (6+2 Pin) x 2, Peripheral (4 Pin) x 5, FDD (4 Pin) x 1|
Another solid entry in our top 5 PSUs for 2019 list, the Thermaltake Smart RGB takes its place for its beautiful design. This brilliant PSU comes with 15 lighting settings which can brighten up any PC gaming setup.
Coming in with another fantastic warranty of 5 years, you'll have peace of mind that you aren't simply buying a product for a year.
The RGB setup is quite unique for our list of PSUs and something which is actually pretty simple to setup. All you really have to do is cycle through all of the options via the one-click button on the back.
80 PLUS certified is something that we always look for in a PSU, it gives you peace of mind that you'll always have enough power. Having this rating and also having a maximum power output of 700W makes us confident in recommending this PSU for high-end single GPU builds.
On to a slightly negative note, you will find that the fan can make a bit of noise under heavy load. You also won't have the convenience of a modular or even semi-modular design for this PSU. If a tidy cable minimal PC build is what you require then you may have to go with one of the semi-modular PSUs on this list instead.
If you are someone that has the following criteria for a PSU:
– RGB lighting
– High efficiency power output
– Suitable for high-end single GPU builds
Then this is the PSU for you!
Summing up, for the price you pay (often sub-$70), you really can't go wrong with the Thermaltake Smart RGB which is why it rightfully deserves the number 3 spot.
4. EVGA 550 B3
|Efficiency Rating||80 PLUS® Bronze|
|Connectors||24 Pin ATX x 1, 8 pin EPS 12V x 1, 2 x 8 Pin PCI Express, 3 x 4 Pin internal power, 6 x 15 Pin Serial ATA power, 1 x 4 Pin mini-power connector|
Moving down, in our number 4 position we have the EVGA 550 B3 which is an ideal quiet solution for light to medium usage.
Much like the rest of the options on our list, it comes with a 5-year warranty that will provide you with peace of mind.
It also comes with a 130 mm long-life sleeve bearing fan that keeps the temperature down under all levels of load.
Even though you can't really see the PSU in most builds, if you need all components to be stylish then the EVGA 550 B3 should be right up your street.
One let down, however, is the fact that is does only come with a 80 PLUS Bronze efficiency rating. This does limit your options and we would only recommend mid-level single GPU PC builds with this PSU.
Overall, a sturdy choice for a gaming PSU that won't break the bank. The fully modular design will also allow for exceptional cable management.
|Efficiency Rating||80 PLUS® Gold|
|Connectors||24 Pin ATX x 1, 4+4 Pin EPS x 1, 6+2 PCI-E x 4, SATA x 8, Peripheral x 3, Floppy x 1, USB x 1|
Last, but certainly not least, the Thermaltake Smart DPS G 750W is a solid entry on our list. Whilst it might not be the most advanced PSU on offer, it is perfectly adequate for all entry to mid-level builds.
With a solid build quality and a 80 PLUS Gold efficiency rating, your components won't ever be left wanting more power.
The DPS G app allows your to manage your PSU via software, this is quite a unique feature. Tagged along with the high-quality Japanese capacitors is a 7-year warranty that will see you through many years to come.
If a low-noise option is what you require from a PSU then this is for you. Even under heavy load, this PSU has been praised for its quiet operations.
Wrapping up this post, the Thermaltake Smart DPS G 750W is a fantastic option for anyone who wants a low-noise, affordable and well built gaming PSU.
Now onto the boring/tech jargon just in case you aren't too familiar on any of the terms used in the post.
What is the difference between a modular and non-modular PSU?
You might have noticed that we have referenced the phrases ‘modular', ‘non-modular' and ‘semi-modular' throughout the post. But what do these terms actually mean?
What is a modular PSU?
A modular PSU is one that comes without any cables attached or connected. You will be provided with the cables and you can plug in any that you require for your setup. This is great for anyone who needs tidy cable management and flexibility.
What is a semi-modular PSU?
This is when the PSU comes with the essential cables already attached. These cables are typically 24 Pin ATX, 8 Pin CPU, a single PCI-E and sometimes a SATA or Molex cable. As expected, semi-modular PSUs are typically cheaper than fully modular options.
What is a non-modular PSU?
As you might have guessed, a non-modular PSU is when all cables come pre-attached to the PSU. This can make cable management a bit of a nightmare. However, typically non-modular PSUs are cheaper.
What is the 80 Plus efficiency rating?
This is essentially an efficiency rating which lets you know how much power the PSU can output at what % load. The scale starts at 80 Plus and goes through different ratings all the way up to 80 PLUS Titanium.
As you might have assumed, the higher up the efficiency scale you go the more power output you can expect whilst your PSU is under load.
