With the increasing size and capabilities of PC components, it is essential to have proper cooling and a reliable power supply. The Power Supply Unit (PSU) is particularly crucial for gaming PCs as it ensures the functionality and protection of components. Therefore, it is advisable to invest in a high-quality PSU that meets or exceeds your needs, while also being cost-effective and quiet.
Since 2022, Intel has introduced the ATX 3.0 standard, leading to the emergence of more ATX 3.0 compliant PSUs in the market. This has become even more important with Nvidia's release of the RTX 4000 series GPUs, which require the 16-pin 12VHPWR connector included in the ATX 3.0 standards. This connector can deliver up to 600W of power through a single 16-pin connection.
Content has been
ATX 3.0 is a new and improved standard with stricter specifications for power supply units (PSUs). However, the implementation of the new connectors initially caused concern as some users reported permanent damage to their RTX 4090 cards due to improper fitting. As a result, many users have chosen to forgo the Nvidia-provided connectors and instead opt for a high-quality third-party cable kit or invest in a PSU that natively supports the 16-pin connector.
Update 7/31/23: Nvidia has made slight adjustments to the 12VHPWR connector on certain founder's edition GPUs. However, it is still advisable to choose a PCI-E Gen 5 PSU with its own cable/connector instead of the ones currently offered with many GPUs on the market. Since this new connector is likely to be the future standard for powering graphics cards, selecting a PSU with a native 16-pin connector or a first-party adapter is a forward-thinking approach. This ensures compatibility with upcoming graphics cards and can be a worthwhile investment in the long run.
MSI MPG A1000G PCIE5 PSU is a recommended option in this buyer's guide. It is compatible with PCI-E Gen 5 cables or can be easily adapted for RTX 4070/4070TI/4080/4090 GPUs. Additionally, ATX 3.0 PSUs are preferred whenever possible by Game Rant.

FAQ
: Making the Right Choice for Your Gaming PC: A Comprehensive GuideQ: What power supply capacity is needed to run an RTX 4080?
A: To power the RTX 4080 Founders Edition, a minimum of a 750W PSU is required. Game Rant suggests opting for an 850W PSU as a safer choice for future-proofing or potential upgrades. However, for those who prefer a more precise limit, a high-quality 750W PSU should suffice for the RTX 4080.
Q: What Power Supply should one get for an RTX 4090?
A: The official specifications provided by Nvidia for the RTX 4090 GPU specify a minimum power requirement of 850W. However, certain AIB partners who offer overclocked versions of the same GPU suggest a 1000W PSU instead. Opting for a 1000W PSU would be a prudent decision as it ensures coverage for all possible scenarios and allows room for additional power consumption if necessary.
Q: What is the recommended PSU to run an RTX 4070TI?
On paper, a 700W PSU should be sufficient to power an RTX 4070TI, which Nvidia rates with a Total Graphics Power of 285W. However, it is recommended to consider a higher wattage PSU for improved efficiency and future-proofing. Game Rant suggests opting for a 750W or 850W PSU when pairing it with the RTX 4070TI.
