Your Power Supply Unit (PSU) has a vital role to play in the life and performance of your PC. But they don’t all come in the same wattage. Today we’ll look at the best 750W power supplies in 2021.
Insufficient power supply can be inimical to your PC life span and of course, your gaming experience (if you’re a gamer) as we discuss in our best power supply for gaming article.
One of the errors caused by an insufficient power supply is Blue Screen of Death (BSOD). Although not limited to a power supply problem, a BSOD can be caused when the power being supplied to your PC isn’t enough for the vital components like graphics card, processor and motherboard.

#1. Corsair RM750x
The Corsair RM750x is one of the most powerful PSUs you’ll find in 2021. To start with, it’s made by a very reliable company that adds good Voltage control to their PSUs – Corsair. This PSU is ruggedly built and equipped to fire up all your power-thirsty components.
In terms of price, you might sweat a little to get this unit because it currently costs over $150 – which is a little higher than most cheap PSUs in the market today. But you have to believe it’s worth the price. After all, it’s better to spend a little extra on a good PSU like this one, than spend thousands replacing a costly component destroyed due to using an insufficient PSU.
What’s attractive about the Corsair RM750x PSU?
The Corsair RM750x boasts an 80 Plus Gold-certified efficiency rating. Inside, you’ll find 105oC Japanese capacitors. It has a boxy design, with a black case shielding the fan inside. The cables of this PSU are all sleeved which is something we like to see.
The RM750x features thermally controlled Zero RPM fan mode – meaning the fans won’t come on until they’re required; this makes the unit one of the quietest in terms of fan noises.
With regards connectors, this unit uses 4 x PCIe 6+2 pin 600mm+150mm connectors, 4 x SATA 400mm+100mm+100mm connectors, 4 x SATA 450mm+100mm+100mm connectors, 2 x FDD Adapter + 100mm connectors.
- Efficient performance
- 10 years warranty
- Not noisy
- Fully modular
- Good cable management
- Not the best design
The Corsair RM750x doesn’t come at a competitive price but the features and performance attracted us to the unit. This is certainly one PSU no gaming rig builder will regret buying.
#2. FSP Hydro PTM 750W
The FSP Hydro PTM 750W is a fully modular PSU that packs a powerful punch, especially given it comes as an 80+ Platinum certified PSU (little or no power gets wasted). Interestingly, the price of this unit isn’t scary, despite the high-efficiency rating.
There are other exciting features that make this PSU a good choice.
Firstly, the product comes in good packaging displaying the brilliant unit inside. The PSU itself emerges in a dark-gray case with the fan vent and connectors clearly visible.
It also uses industrial-grade capacitors like the Corsair PSU we looked at earlier. Given it’s a fully modular PSU, you can save space by using only the cables you want. By the way, you get ribbon cables, which adds to the excellent cable management offered by this unit.
The product ID comes with changeable stickers, for enthusiasts who like to get a little tweaky with their stuff.
The FSP Hydro PTM 750W uses a 135mm FDB fan, with well-thought-out thermal layout design. The fan isn’t noisy compared to others we saw.
And this PSU is NVIDIA SLI ready – making it one of the best for a hard-core gamer.
Finally, we must mention that the Hydro PTM 750W is approved to offer complete protection for low or high voltage, current and surge.
- Good price
- Fully modular design
- Not Noisy
- Enough cabling and good cable management
- Large chassis
- Low hold uptime
In terms of dependability, price, performance, and design, we’ll gladly recommend the FSP Hydro PTM 750W. You may easily overlook it in the market because it isn’t a popular product, but this is one good PSU you can find.
#3. Cooler Master V750
Here is another 80+ Gold efficiency rated PSU – the Cooler Master V750. Besides being a reputable brand with regards to producing these type of units, the Cooler Master V-Series is one of their proudest work with regards to power supplies.
The Cooler Master V750 comes in a very compact fully modular design. It uses a Silencio 135mm FP fan – which claims to generate 25% more pressure to curb thermal dissipation. Actually, the vibrations from this fan were minimal, but from what we saw, it made some noticeable noise especially when load increases.
Under normal load, this PSU still proved 90% efficient, which isn’t unexpected given the 80 Plus Gold rating it advertises. Like the others we’ve looked at, this PSU uses those long-lasting Japanese capacitors – rated 105oC.
We must also commend the 3-D circuit design of the V750. This was largely done to give the unit that compactness we mentioned earlier. And of course, that improves the efficiency of this unit – especially with heat dissipation.
Cooler Master offers a five-year warranty if you buy this product.
- Compact case
- Efficient and good performance
- Fully modular design
- Fan gets a bit loud when active
- Uncompetitive price
Some purists have declared the Cooler Master V750 the best power supply unit of 2021. You can’t really fault their perspective. This is one beastly PSU that doesn’t disappoint in terms of design or performance. However, if you’re looking for a budget PSU, you best look elsewhere.
#4. Rosewill Capstone G750
You may not find a more affordable and efficient PSU like the Rosewill Capstone G750. Tell you what: it’s not at all easy to find a PSU with 80 Plus Gold Certified rating under $100.
If you do a little research on Rosewill you’d discover their products are quickly gaining rep in the market – and there are a handful of decent reviews on Amazon to back up this notion.
So what’s special about the Rosewill Capstone G750?
If you judge this by the boxy, black-cased design you might be quick to overlook it, but take a second and check what’s under the hood.
It uses a fixed cable 1 x 20+4-Pin main connector. The modular cable is 2 x 4+4-Pin ATX12V/EPS 12V connector. Add that to the 4×4-Pin 8 x SATA connector and the 4x PCIe 6+2-Pin connector.
There’s a lot of space inside this PSU which makes it one of the coolest PSUs we reviewed. Besides that, it uses a 135mm to clear out heat, which somewhat surprised us by how quiet it was even under load.
Finally, this isn’t a fully-modular PSU – the Rosewill Capstone G750 is a semi-modular PSU. What that means is, this isn’t the best PS in terms of cable management since some of the cables are hardwired to the unit. You can’t detach what you’re not using.
- Budget price
- Good performance – for the price
- Not noisy
- Not fully modular [semi modular]
The Rosewill Capstone G750 is an impressive PSU if you look beyond the fact it’s a little bulky and isn’t fully modular. This type of PSU can easily become clumsy for your gaming rig if you’re not organized. But overall the G750 has earned its place based on how well it performs and the efficient power management it offers.
#5. Seasonic Focus Plus SSR-750FX
Talking about PSUs that come in an overly boxy and sturdy build – the Seasonic Focus Plus SSR-750FX is a prime example. But despite all that, it still manages to depict some cuteness.
The first thing that greets the eye is the big golden pack containing this PSU. Unbox it, and you’re met with the defiant fully-modular, 80+ Gold Certified Seasonic Focus Plus SSR-750FX.
The Seasonic Focus Plus is one case where good price meets good performance. Under 50% load, it’ll romp out 90% efficiency. That’s what you get when you buy a Gold-certified PSU.
But you shouldn’t complain too much if you hear some noise from the fan. The three fan modes [fan-less, silent, cooling modes] didn’t give us the silence we’ve come to enjoy with some pricier PSUs. The fan modes can be controlled manually by a button close to the power button.
But you’ll appreciate the 135mm fan is thermally controlled, so it doesn’t come on until the system starts heating up.
The loudest we got from the fan was when it entered cooling mode – with the load exceeding 50% and heat considerably on the high.
- Good price
- Superb performance
- Good cable management – fully modular design
- 10 years warranty
The Seasonic Focus Plus is an affordable high performer. You can see by the rating. It even offers safety protection against over-voltage, under-voltage and power surge. We’ll recommend this PSU to anyone on a low budget in search of a 750W PSU.
#6. EVGA Supernova 750 P2
The EVGA Supernova 750 P2 is a superb power supply unit from a brand with a burgeoning reputation. It’s no surprise then why this product has continued to receive rave reviews, particularly on Amazon.
The first thing we’ll like you to know is that this unit is 80 Plus Platinum certified. If you’re wondering why we placed such a decent unit down the list, it’s because of the price. We think it’s pricey. Although the value for money is good with this purchase.
The Supernova 750 P2 isn’t the only one in its category from EVGA – this is basically the 750w unit from the EVGA Supernova series – there are others, ranging from 600W to 1600W.
Based on the energy rating, this PSU doesn’t consume energy unnecessarily. And it’s an excellent unit for SLI.
The thermally controlled fans [thanks to ECO mode] means the fans will only come on when temperature clocks 45oC. They’re quiet. And you have those notorious 105oC Japanese capacitors which don’t die easy.
No cables are hardwired into this PSU – telling you it’s a fully modular unit. How about the fact you get a 10 years warranty on the product for purchase? Sounds cool, doesn’t it?
- Efficient performance
- Fully modular
- Features Eco mode for low noise
The Supernova 750 P2 is a truly outstanding PSU. The price may put people off, but if you’re looking at getting a good bang for your buck, then you’ll absolutely buy it without blinking.
#7. Seasonic SSR-750TD
Have heard of a Titanium Certified PSU before? Well, we present the Seasonic SSR-750TD PSU – a rarity in the market and a truly efficient performer.
Kindly note that this is an Analog PSU – that’s partly why this unit isn’t very popular in the market. Besides that, the Seasonic SSR-750TD has everything you want in a modern-day PSU.
In terms of reliability, this unit won’t disappoint. It even offers more efficiency than the flashy ones up there on this list – at under 50% load, you’ll get 95% efficiency. That’s a scary and intimidating number, and you might think it makes a hell of a noise, but it doesn’t.
This PSU uses a tough 135mm dynamic bearing fan that makes next to no noise, even under high performance.
The Seasonic SSR-750TD is a fully modular PSU so there’s no clutter with cables.
Finally, Seasonic went two steps ahead of everyone else to offer a 12-year warranty on this product. That’ll outlive any gaming rig
- Low noise
- Staggering 12-year warranty
- Fully modular
The Seasonic SSR-750TD isn’t really a conventional power supply. The Titanium energy rating says it all. But we really like it. This is one PSU you can buy and go to sleep. But you’ll have to be ready to spend.
#8. EVGA 750 BQ
In 2010, EVGA started producing some cool computer components – among those was one of the efficient power supply units we saw – the EVGA 750 BQ.
The EVGA 750 BQ comes in a design that doesn’t really inspire much confidence like its other sibling we reviewed earlier – this one is sturdy and a little bit too minimalistic. But when considering PSUs, the design shouldn’t be an important factor in making a choice; performance is.
So let’s look at what this PSU has to offer in terms of performance.
The EVGA 750 BQ is the cheapest 750w PSU we found. Although the incredibly low price came at a small sacrifice.
Unlike any other PSU here, this is rated 80+ Bronze Certified. So while others will give you a 90% efficiency under 50% load, this unit can manage just 85% efficiency. Not bad for PSU under $50? That’s up to you to decide.
This PSU uses one of the biggest fans we saw – a 140mm fan with Teflon Nano steel bearing. It’s fairly noisy though; expectedly, but it really keeps the EVGA 750 BQ cool.
With regards to cabling, we must tell you that this is a semi-modular PSU. At least it’s better than non-modular.
This PSU offers all the heavy-duty protection you’ll get from other pricier options. Like short circuit protection, under/over current protection, over-power protection and over/under voltage protection.
You get a five-year warranty after buying it.
- Very affordable
- Good value for money – with regards to performance
- Low-efficiency rating
- Not the best in terms of Cable management
The EVGA 750 BQ is a decent PSU. But it’s not the best on this list. We just added it for our readers who may really be low on budget and need a PSU. Overall, you won’t have much to complain about when you own it.
Why you should buy the best 750W Power Supply?
If you don’t buy the right PSU, you risk fatally damaging your pricey components.
We understand there are so many PSUs in the market with different wattage rating. This means you can easily get inundated with options and that could lead you to the wrong choice.
The first thing you should look at is your components and the quality of the PC you have.
A 750 Watt PSU is perfect for you if you’re building a high-performance computer like a gaming rig. This is the perfect wattage for you if want your components to run smoothly. You will play high-quality games at ultra-settings and run powerful software without experiencing lagging or crashing.
