When you’re on a tight budget, it can be tempting to ignore the big brands and go for the cheapest power supply available. In some cases it may even be fine for you, but we can’t stress enough that power supplies need to be thought through carefully. Spending a few extra dollars can mean the difference between a simple power failure or a catastrophic failure that destroys your entire machine.

The Cooler Master MasterWatt series is our preferred choice for low budget builds. These are not the cheapest power supplies out there, but they offer much more than their cheaper counterparts. 80 Plus, Bronze certification, a clean design with semi-modular cables, and an excellent five-year warranty make the MasterWatt a safe bet with excellent value for money for users on a budget.

If you’re building a budget gaming PC and need a low-budget power supply, we recommend the MasterWatt 750. It packs an excellent 750W power, but the 80 Plus Bronze’s efficiency isn’t great. However, it will be perfect for powering a rig with low to medium specs. The power supply is also semi-modular, which means that it can only move part of the cables. Fortunately, the 120mm fan is efficient for cooling and runs quietly. All in all, this PSU is for people who want to get their hands on a very affordable low-end PSU that will serve their budget PC well. Getting this power supply is not recommended if you plan to upgrade your hardware in the near future.

FDB (Fluid Dynamic Bearing) fans are designed to take advantage of the shock absorbing effects of oil. They are reliable and generate much less operating noise and heat than ball bearing fans. Lubricating the running surface reduces friction and vibration and therefore reduces overall energy consumption. Due to the quieter, effortless rotations and durable construction, this reliable fan technology also increases the life of the fan. Seasonic’s 3-phase thermal control provides optimal peace of mind and cooling. This hybrid silent fan control operates in three operational stages: fanless mode, silent mode, and cooling mode. The benefits of this design include reduced noise, longer fan life, optimized heat dissipation, and quiet performance in fanless mode. Additionally, there is a switch on the back of the power supply that allows you to customize the cooling by selecting between Seasonic S2FC (fan control without fanless mode) and S3FC (fan control including fanless mode. Fan).

If you plan to build with multiple high-end GPUs, you will need a power supply with exceptional power output, as well as efficient operation. Seasonic has long been an industry leader and its Focus Plus Platinum PSU draws on all of its experience. There are a number of innovative features such as an internal cable-free design, a compact size despite its power output, and fanless operation at low loads to reduce noise and extend fan life.

Although it is fully capable of running multiple GPUs, check your cable requirements as the power supply comes with 3 GPU cables and the most powerful GPUs require 2 each. Perhaps it was the cost of the gold connectors that led Seasonic to refuse to supply this power supply to the entire quartet? This PSU is a simple, high-spec unit with a 10-year warranty and outstanding thermal and acoustic performance, meaning you can buy with confidence to run a workstation, laptop, and more. , or an avid overclocked gaming computer.

If you’re looking to build a compactness-focused gaming rig, we recommend checking out the EVGA SuperNOVA 1200 GM. It has 1200W of power and an 80 Plus Gold efficiency rating, and it has a 93mm fan that cools quite efficiently, but not as well as the other fans on this list. The fan is also a bit noisy when in operation, but the power supply is fully modular. It is also very compact, which makes it perfect for fitting into smaller PC cases. It delivers the power of a midrange PSU in the size of a low budget, and at a pretty solid price as well.

As you would expect from a product in this price range, the cable system is fully modular in nature. It will lead to a clutter-free experience when connecting various components. Plus, the cables are braided so they don’t get tangled. EVGA also used high quality components inside. We say this because all capacitors and other vital parts are made by Japanese companies.

This makes it a reliable product that will last a long time. On this premise, EVGA has been confident enough to provide a 10 year warranty on the Supernova 1200. The fan size is 140mm and it is manufactured using a double ball bearing configuration. You’ll be happy to know that no user has reported any issues with its noise level or cooling speed. However, its huge size and weight is a downside. All of that put into perspective, we have to say that you won’t go wrong with purchasing this high capacity power supply. In f

Seasonic Electronics’ PRIME 1300W 80 Plus Gold ATX Modular Power Supply helps users strike a good balance between efficiency, performance and power, while its power range makes it suitable for heavy gaming and overclocking. This power supply features a single + 12V rail that delivers up to 1300W of power to 12 PCIe, 12 SATA, 5 molex, and other essential connectors. It is 80-PLUS Gold certified for efficient energy use, while cooling is done by a built-in 135mm fan with a smooth dynamic bearing. Other features include a flat modular cable design, which helps improve airflow through the system by reducing the number of unnecessary cables.

The SSR-1000PD Ultra is one of the best power supplies you can buy today. It’s clear proof that skilled engineers can extract performance from analog circuits that years ago we only thought possible with digital platforms. The + 12V rail of this power supply has one of the toughest charging regulations we’ve ever measured, while its other rails perform well as well. The ripple suppression is excellent, its transient response is top notch, the hold time is very long, and you get all the protection features you could want (although the OCP point of the 5VSB rail allows for high ripple under loads. heavy).

Although Seasonic’s best-selling power supplies come from the Focus series, combining good performance with affordable prices, its Prime Ultra line gets all the prestige. The loud noise we saw on the original Prime PSUs is resolved (Platinum and Gold models benefit; the Titanium series was already much quieter). And the removal of capacitors from modular cables, while maintaining extremely low ripple, is also a major breakthrough, allowing modular cables to take up less space. Speaking of cables, we should mention this unit’s 180o SATA connectors and SATA 3.3 support, which could come in handy if you want to take advantage of the power off (PWDIS) feature that some hard drives offer.
