Yes, a 680W be quiet power supply should be sufficient for most mid-range to high-end gaming PCs. Be quiet power supplies are known for their high-quality components and efficient cooling, which helps reduce noise levels. However, if you have a particularly power-hungry system or plan to do heavy overclocking, you may want to consider a higher wattage power supply. Ultimately, the noise level will also depend on the overall system configuration and how well it is optimized for airflow. **

Yes, a 550W power supply is sufficient for a Ryzen 7 processor. The Ryzen 7 series of processors have a TDP (Thermal Design Power) ranging from 65W to 105W, depending on the specific model. This means that a 550W power supply should provide enough power to support the processor, as well as other components such as the graphics card, memory, and storage devices. It's always a good idea to check the power requirements of all your components to ensure that the power supply can handle the overall load. **

No, it is not recommended to build a system with a GTX 780 Ti and a 550W power supply. The GTX 780 Ti has a TDP (thermal design power) of 250W, which is quite high, and it is recommended to have a power supply of at least 600W to ensure stable and reliable performance. Using a 550W power supply may lead to system instability, crashes, or even damage to the components due to insufficient power delivery. It is always best to use a power supply that meets or exceeds the recommended wattage for the components in your system. **

The new power supply Dark Power Pro 11 550W may smell bad due to the manufacturing process and the materials used. The smell could be a result of the components and insulation materials heating up for the first time, which can release a temporary odor. Additionally, the power supply may have accumulated dust or other particles during storage or shipping, which can also contribute to the smell. It's important to ensure that the power supply is properly ventilated and that any initial odor dissipates over time. If the smell persists or seems unusual, it's best to contact the manufacturer for further assistance. **

To find the current, we can use the formula P = IV, where P is power, I is current, and V is voltage. Rearranging the formula to solve for current, we get I = P/V. Plugging in the given values, we get I = 550W / 220V = 2.5A. Therefore, the current is 2.5 amperes when the power is 550W and the voltage is 220V. **

The BeQuiet System Power B8 550W 80 is a decent power supply unit that should be sufficient for most mid-range gaming or productivity systems. However, if you are planning to upgrade your system with more power-hungry components such as a high-end graphics card or multiple storage drives, it might be a good idea to upgrade to a higher wattage power supply to ensure stable and reliable performance. It's always a good idea to calculate the power requirements of your system based on the components you have or plan to install to determine if an upgrade is necessary. **

No, you cannot keep the DSL hardware from 1&1 after the contract period expires. The hardware provided by 1&1 is typically leased to customers for the duration of their contract, and it must be returned at the end of the contract period. If you wish to keep the hardware, you may have the option to purchase it at the end of the contract, but this would depend on the specific terms and conditions of your agreement with 1&1. **

A 550W power supply may be sufficient for an RTX 2080 Ti and a Ryzen 5 3600, but it would be cutting it close. Both components are power-hungry, especially the RTX 2080 Ti which has a high power draw. To ensure stability and longevity of your system, it is recommended to use a power supply with a higher wattage, ideally around 650W or more, to provide enough headroom for peak power demands and potential future upgrades. **
