Building a PC for mid-range gaming, streaming, and content creation means having a powerful CPU that can muster both single-core and multi-core performance, and a GPU that can handle 1440p 144 Hz and 4K 60 FPS gaming, as well as editing software like Premiere or DaVinci Resolve, After Effects, and Photoshop.
The two components that fill these specifications perfectly, are the AMD Ryzen 7 5800X CPU, and the Nvidia GeForce RTX 3070. This CPU holds a respectable number of cores and threads (8/16), together with AMD’s new Zen 3 CCX architecture, so it can handle both gaming and content creation. Also, unlike AMD’s new series of Radeon RX 6000 series graphics cards, the GeForce RTX 3070 has respectably high editing benchmarks, so together they can make a great all-around hybrid build.
To power these components, you will need a power supply of equally high quality. The GeForce RTX 3070 requires 220 watts of power to operate, and the Ryzen 7 5800X requires 105 watts, so a PSU of 750 watts will suit the build perfectly; keeping the loads at around 50-75%, where efficiency levels are best.
Let’s take a look at some of the best options available in the market, for different requirements and preferences.

Both the GeForce RTX 3070 and the Ryzen 7 5800X are quite expensive, costing almost a thousand dollars combined – and that’s if you find them at their MSRP – so, if you’re looking for supplementary components to be as cheap as possible, we recommend the Cooler Master Watt 750.
This power supply has an 80 PLUS Bronze rating certification, meaning it has an efficiency level ranging 82% to 85%; which is satisfactory if you don’t plan on using your PC for too many hours and on a daily basis.
Despite its lower price tag, the Watt 750 has a single +12V rail that can output its full 750 W (54.1 amps) potential, which means you don’t need to worry about having enough power supplied to your CPU or GPU.
In terms of its thermal solution, the Watt 750 uses a PWM controlled 120 mm Corsair Silencio FP fan, which includes Loop Dynamic Bearings and an IP6X dustproof certification, that Cooler Master claims reduces vibrations, noise, and increases the life expectancy of the fan to up to 160,000 hours.
But the best aspect of the Watt 750 is its price, as you can currently find this semi-modular PSU for just $84.99 – down from its original $94.99 MSRP.
If you plan on having your PC setup also be a centerpiece for your desk, room, or office, then the more components you can find with an RGB flare, the better, and that includes the power supply. Luckily enough, Super Flower has you covered with their Flower Leadex III.
This PSU has not one, but two ARGB illuminated displays: a crystal connector panel design opposite the back I/O ports, and a 130 mm ARGB illuminated fan with translucent blades and premium fluid dynamic bearings. This fan is also PWM controlled, so temperatures and noise levels will be kept at an absolute minimum.
But the Leadex III is not just all about looks. It has an 80 PLUS Gold rating, which guarantees efficiency levels ranging from 87 to 90%, a fully modular cable design, a single high power +12V rail that can output 748.8 W (62.4 A), and all-Japanese 105-degree certified capacitors. It has been tested for over 2,000 on/off switches, and even includes an impressive 10-year warranty with free shipping for any potential exchange.
The Super Flower Leadex III might be a bit expensive, but for what it offers it is worth every dollar. You can currently find it for $178.99.
For those looking to make a small, yet powerful, Small Form Factor (SFF) PC with the Ryzen 7 5800X and the GeForce RTX 3070, you will need an equally powerful SFX PSU with a high energy efficiency level; to prevent the PSU from transferring heat to the other tight-fit components that are prone to thermal issues. The best power supply for the task, is the Corsair SF750.
This fully modular PSU has an 80 PLUS Platinum certification (90%+ efficiency), a single +12V rail that can output 750 W (62.5 A), a PWM controlled 92 mm fan that will only operate at loads above 40%, individually sleeved cables with flexible paracord sleeves, an SFX to ATX bracket (for those that need a small PSU for an ATX build), a Mean Time Between Failures (MTBF) of 100,000 hours, and a 7-year warranty.
The Corsair SF750 has an MSRP of $184.99, but the price does fluctuate according to availability.
Last but not least, we have an option for those that seek to build a silent PC, devoid of any low-frequency humming or monotonous droning sounds: The be quiet! Straight Power 11 750 W.
This PSU includes a 135 mm fan made with be quiet!’s Silent Wings 3 design, high-end fluid dynamic bearings, a 6-pole fan motor, and static pressure optimized fan blades. This translates to noise levels that range from 8.6 to 20.8 decibels – which is ultimately inaudible from a foot away.
Like the aforementioned SF750, this power supply is also 80 PLUS Platinum rated, but it is different in that it has multiple high power +12V rails – four to be exact. These rails, though independent from each other, are separated into two pairs: one pair outputting 20 amps, and the other pair outputs 24 amps for a total of 84 amps, or 820 watts.
All the capacitors within are 105-degree Celsius certified and Japanese manufactured, all its cables are fully sleeved (fully modular), and the internal components are wire-free, so thermals will always be low.
You can find the be quiet! Straight Power 11 750 W PSU currently for $169.99, which is a great deal for the performance and value this silent power supply offers.
