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 Rating80 PLUS® Gold
+12V RailsSingle
ModularSemi-Modular
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
Warranty5 Years

Pros

  • Greater than 80% efficiency
  • Great build quality
  • SLI certified
  • Great value for money
  • Can output full power even when ambient temperatures run high

Cons

  • Can get a little noisy under load

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.

3. Thermaltake Smart RGB

+12V RailsSingle
ModularNon-Modular
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

Pros

  • 5 year warranty
  • 80 PLUS efficiency
  • Power output remains at 100% even at high ambient temperature
  • Incredibly good value for money (sub-$70)
  • Easy RGB configuration via a button

Cons

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:
– Budget-friendly
– 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

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

Pros

  • Low-noise even under load
  • Highly affordable
  • 5-year warranty
  • Fully modular

Cons

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.

Glossary

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.
