ATX 3.0 is the new specification standard for PSUs. This new design adds a new PCIe 5.0 connector with 12 + 4 pins alongside the usual 6 or 8-pin connection. A Phanteks Revolt power supply can match the needs of modern components. With many high-performance CPUs requiring over 200W and GPUs reaching 450W+, an 850W supply is highly recommended. With its modular design, the Revolt PSU can support a wide variety of devices including NVIDIA RTX 40 Series GPUs, thanks to its dedicated 12VHPWR output. This new connection can deliver an astounding 600W along a single cable. All power is supplied safely thanks to the many forms of output protection Phanteks has built into the design, including Overpower, Over Voltage, Short Circuit, and Over Temperature protection. A fully modular power supply unit lets you use only the cable you need for simple and clean cable management. Once you have decided on the form factor and modular design, the next thing you need to consider is the efficiency rating you can afford.

Almost all PSU manufacturers design PSUs with the 80 Plus efficiency rating certification. The “80 Plus” rating system is the industry standard! ATX power supply units are usually the industry standard for most builds. They are designed to fit the regular ATX, large EATX, and most mATX PC cases. But some manufacturers also design them in white colors to cater to builders looking to build sleek, all-white gaming PCs.Simply put, an 850W 80 Plus PSU will draw a maximum of 1,062.5W at 100% load, which means less wattage is wasted as heat in the conversion process, saving your energy bill. To be 80 Plus certified means that the PSU has at least 80% efficiency at three load levels of 20, 50, and 100 percent loading. Most gaming builds will need power ranging between 450 to 650 watts unless you use a powerful GPU like the recently released RTX 4090.

After deciding on the PSU wattage, the next thing you need to consider is the form factor. They’ll either come in the ATX or SFX form factor. The PSU controls the system’s power supply for optimal performance and protection, making it the heart of any gaming PC build. The Corsair RM850x power supply is highly regarded by most builders. It’s fully modular and has an 80+ Gold efficiency rating. The 80 Plus Gold efficiency rating is usually the sweet spot for most gaming PC builds. Anything above this is overkill and quite expensive! ATX 3.0 Compatible The Phanteks Revolt PSU has been designed to offer outstanding performance and efficiency. Thanks to this, these PSUs can produce exceptional power output with minimal cooling. In fact, the cooling fan won’t even activate until the PSU reaches 30% load for zero noise. Once this load is reached, optimum temperatures can be maintained, thanks to the Revolt’s intelligent temperature control, which carefully balances cooling performance and noise levels. In addition to being whisper quiet, the 92mm fan’s fluid dynamic bearings also reduce vibrations which is ideal for minimising wear and tear. In fact, Phanteks is confident in every component within the Revolt SFX, that they offer an amazing 10-year warranty. Phanteks Revolt 850W SFX PSU Specifications: ATX 3.0 CompliantThe new connector is meant to make the power supply PCIe 5.0 ready. They have high power delivery for GPUs with up to 600W of power. Semi-modular PSUs have only the most important cables attached, with room to add extra cables as needed.

It’s almost impossible to find a non-modular 850W PSU. But some manufacturers design semi-modular ones which are affordably priced.My favorite feature about it is the zero RPM fan mode that offers near-silent operation at low to medium loads. Pros: You’re more likely going to need an ATX power supply. That’s unless the case manufacturer specifically states you use an SFX one. Modular Design

But SFX PSUs come in smaller designs to fit in small form factor (SFF) cases because they don’t have the space needed to fit a full-size ATX PSU. I recommend getting a fully modular PSU since it offers total control of your build’s cable management. Efficiency RatingThe 80 Plus efficiency rating has since expanded in recent years to categorize different PSUs from the least to the most efficient. I presume you already have the estimated total wattage that your PC will draw, and an 850W PSU is the ideal power supply unit to complete the build. A non-modular PSU has all the cables permanently attached, while a fully modular design has no cables attached.
