Is 750w Enough For RTX 3080 And 5900x?

The answer to whether a 750W power supply is enough for an RTX 3080 and a Ryzen 9 5900X is not entirely clear.

Some sources suggest that it should be enough, with a bit of headroom, while others recommend an 850W+ power supply for optimal performance.

Some users have reported random shutdowns with a 750W PSU and a 3080/3090.

It is important to consider the total system wattage, including other components such as fans, hard drives, and SSDs.

Ultimately, it may depend on the specific components and usage of the system.

Are There Any Power Supply Brands Or Models That Are Particularly Recommended For Use With The RTX 3080 And Ryzen 9 5900X?

Yes, there are power supply brands and models that are recommended for use with the RTX 3080 and Ryzen 9 5900X.

NVIDIA recommends a power supply of at least 750W for the RTX 3080.

TechReviewer recommends the Thermaltake Toughpower GF3 ATX 3.0 power supply for use with the Ryzen 9 5900X.

Other recommended power supplies for the RTX 3080 include the EVGA SuperNOVA P2 750 and other high-quality power supplies listed in articles such as “Best Power Supplies of 2023″ and “4 Best Power Supplies for Ryzen 5 5600X Builds”.

It is important to choose a power supply with enough wattage and high efficiency to ensure stable and reliable performance.

What Factors Determine The Total System Wattage Besides The Graphics Card And CPU?

Besides the graphics card and CPU, other factors that determine the total system wattage of a PC include the power supply unit (PSU), form factor, efficiency, amperage, protection, cables, overclock settings, and peripherals.

While it is possible to calculate the total power consumption of a PC, the aggregate figure is mostly theoretical and may not be reached under real-world conditions.

It is recommended to choose a PSU that can provide a bit more power than what is calculated to have some headroom for future upgrades or to handle peak power usage.

Can A Lower Wattage Power Supply Lead To Performance Issues Or Damage To The Components?

Yes, a lower wattage power supply can lead to performance issues or damage to the components.

Using a power supply that is too weak can cause screen freezes, black screens, and slower performance.

Additionally, a low-quality power supply can damage your components over time.

It is important to use a power supply that is appropriate for your system to avoid these issues.

Are There Any Software Tools That Can Help Monitor Power Consumption And Prevent Overloading?

Yes, there are software tools that can help monitor power consumption and prevent overloading.

Power monitoring can be achieved by using power monitors, sensors, and meters to monitor devices including uninterruptable power supply (UPS) units and power distribution units (PDUs) .

There are also software tools available to measure and monitor energy consumption, such as PowerTOP.

Additionally, there are programs that can measure your PC’s power consumption, such as the one mentioned in and.

What Are Some Signs That Indicate A Power Supply Is Not Providing Enough Power To A System?

There are several signs that indicate a power supply is not providing enough power to a system.

These include:

  • Computer randomly shutting down or rebooting
  • Applications crashing, running slowly, or not running at all
  • Blue screen of death
  • Strange noises coming from the computer or device
  • Computer not booting up
  • Battery light blinking rapidly and the battery icon indicating the computer is operating on battery power
