Often neglected, food is nevertheless central to the good health of your PC. We have chosen for you the best models according to your use.
Indispensable to any PC, the power supply is a component that is often overlooked. After all, it brings no visible gain to the screen. However, this is a serious error, because a bad choice of power supply may not be able to start your PC, but above all damage your components, or even cause a fire in the worst case.
After nearly a year of severe tension in the power supply market, caused by component shortages and high demand from cryptocurrency miners, things have thankfully calmed down. Not only have prices gone down again, but above all stocks are there again! This is particularly noticeable for models over 1000 Watts, which had become almost impossible to find.
Here we have selected some of the best PC power supplies for the most common use cases.
Looking for other components to build your gaming PC? We have what it takes to choose well:
Corsair CV450 80 Plus Bronze: the PC power supply for small configs
An entry-level configuration, equipped with a small graphics card or even content with an integrated graphics circuit, does not consume a lot of energy. That doesn’t mean you should cut corners, though.
With its 450 Watts and 80 Plus Bronze certification, the Corsair CV450 is a perfect choice for a small machine. So certainly to reach this price we must do without modularity or even semi-passive mode. But the design is serious and the internal components of quality. No risk therefore of seeing your PC power supply (and your tower) go up in flames.
Fox Spirit US-650G V280Plus Gold: PC power supply for everyone
Private label products are rare in the tech world. The French LDLC is however one of the few shops to have embarked on the adventure, with in particular power supplies. If this 80 Plus Gold-certified 650W power supply model reminds you of something, that’s normal. This is indeed a rebadged Seasonic reference.
We therefore find a 100% modular model, capable of operating passively when the load does not exceed 50%. This means that it will produce no noise in most cases. Nothing to say either about the quality of the current and the number of cables provided.
The only real compromise: the warranty, which is only 3 years compared to 10 at Seasonic. An exchange that we are happy to do since going through LDLC saves you 25 euros! Simply put, here you have the power supply that will suit most users. However, do not plan to use more greedy than an RTX 3070.
EVGA Supernova 650 G5: the compact format
EVGA is a safe choice for PC power supplies. Among the power supplies available on the market, this one stands out for its rather unusual compact design. Despite its small dimensions, it delivers satisfactory operating power for your gaming configuration.
This power supply is certified 80 Plus Gold and delivers a maximum power of 650 Watts. The product is therefore perfect for a mid-range gaming PC configuration. You will thus find yourself with a reliable power supply, but above all sufficiently silent in operations for an overall quality experience. Above all, it is a rather accessible food for the quality offered.
Corsair RM750: for an immaculate configuration
For some, the performance of their setup is just as important as their style. Within the Corsair RM750 range, a white version of the power supply is offered for those who want an immaculate configuration.
In addition to its particular color, the Corsair power supply is also efficient. It delivers a power of 750 Watts and has an 80 Plus Gold certification. Here too, the product is 100% modular while offering silent operation. Within its construction, it incorporates three EPS12V connectors for complete compatibility.
If you want more performance, it is also possible to choose the 850 Watt version.
Fox Spirit US-850G 80Plus Gold: the PC power supply for demanding gamers
Did you fall for an RTX 3080 and a powerful processor like an Intel Core i7-12700K? It’s going to take juice to power it all up! With its 850 Watts on the clock, this model will have no problem taking all that and even has enough to see for the future.
Like the model mentioned above, this Fox Spirit is in fact a high-end Seasonic power supply produced under a white label for LDLC. We therefore find a modular construction, quality components and perfect operating silence. All for an attractive price and above all a product in stock.
Seasonic Prime GX: the almost top-of-the-range food
Gaming power supplies cater to all types of budgets and with the Seasonic Prime GX, it’s the top of the line that’s at stake. If several versions are available within this range, we have decided to present the more accessible Prime Gold.
With the 850 W of power delivered and its certification, the Seasonic power supply is clearly among the most efficient. It performs its operations silently, but above all the Prime GX has an essential asset. This one is 100% modular allowing you an easy installation. The other point to note is that a 12-year warranty is available on the product.
The only real barrier to buying is its price, but if you can afford it, go for it.
Corsair HX1200i: for oversized PCs
Few are the configurations requiring more than 1000 W, but they exist. A machine dedicated to creation, equipped with a pair of GeForce RTX 3090 and a greedy processor like an AMD Ryzen 9 will have no problem going over it.
A powerful power supply will therefore be essential and this Corsair HX1200 fills all the boxes. Offering a power of 1200 Watts, it is also certified 80 Plus Platinum. Considering the price, the services are first-rate, with an impeccable finish and small onion tensions.
Before buying your PC gamer power supply
What power for my PC power supply?
To choose a power supply adapted to your configuration, you must add up the consumption of the components. This can quickly become laborious and there are several online calculators. Simple to use and regularly updated with the latest components, OuterVision’s is our favorite.
However, here is a quick summary to know the diet you need:
- For an entry-level office/gaming configuration: 450 W
- For a mid-range gaming configuration (RTX 3060/3070): 650 W
- For a high-end gaming configuration (RTX 3080): 850 W
- For a multi-GPU configuration: 1200 W
Bronze, Silver, Gold: what do power supply certifications mean?
Launched in 2004, the 80 Plus program is a private certification guaranteeing a certain energy efficiency depending on the load level of the power supply. This results in less consumption and less heat generation. Thus a certified Bronze power supply offers 82% efficiency at 100% load where a Titanium offers 90%.
In practice, the 80 Plus Gold certification represents for us the best value for money. Going over the top will only raise the bill unnecessarily. We also strongly advise against buying a Bronze power supply if you have a gaming PC.
Is modular or semi-modular wiring useful?
Formerly reserved for the very top of the range, the removable and modular cables of a power supply can now be found at reasonable prices. They are certainly optional, but they greatly simplify the assembly and the “cable managementfrom your PC. This is all the more crucial as the number of components that need to be connected is increasingly low. Unless you really need a few dollars, do yourself a favor and simplify your life with a modular or semi-modular power supply.
