Is 80 CRI good enough?

Color Quality that is Acceptable For LED and fluorescent bulbs, 80 CRI is typically used as the baseline CRI level. It is unquestionably a respectable degree of color quality, with the most noticeable hues standing out and seeming adequate for daily chores. LEDs are becoming more efficient every year, so if you can live with less-colorful light, go for it.

The number next to the CRI rating indicates the amount of colors that will be displayed when looking at an object that is completely white from side to side. If you tilt your head back and look up at the night sky, you're seeing objects that are slightly red, green, or blue because that's the range of colors in the sky. The closer the CRI value is to 100, the fewer colors will be visible to the human eye. So, if you need to see all kinds of colors in your lighting environment, look for lights with higher CRI values.

CRI does not take into account how much color temperature your light source has. Even though both incandescent and LED bulbs have a CRI of 100, they appear quite different due to their difference in color temperature. Incandescent bulbs are very warm, around 3000 K, while LEDs are near 5500 K. Objects appear more yellow under cold white light and more blue under hot white light.

Which is better: 80 plus white or 80 plus bronze?

"White" (sometimes known as "80 Plus") is the lowest (worst) 80+ rating available. (EDIT: This does not necessarily imply that it is a terrible power supply; there are lots of PSUs that do not have 80 plus certification.) It simply indicates it is less efficient than competing power sources with higher ratings. Bronze, silver, and gold all indicate greater efficiency, with silver being more common than gold.

All other factors being equal, an 80-plus power supply will use less electricity than one with a lower rating. However, higher-rated supplies tend to be larger and more expensive than lower-rated ones of the same size. They also produce more heat. Thus, you should pick a capacity suitable for your needs and budget; don't buy an industrial-strength unit if you won't be able to handle the heat it produces.

The number in the designation doesn't refer to a specific percentage of rated capacity, but rather shows the minimum power factor required to obtain the rating. For example, an 80-watt unit must meet this requirement to be considered 80 watts. A power supply that falls short of this requirement may still be more efficient than one that meets it, but it cannot claim to be 80 percent efficient.

A power factor above 0.9 is recommended for high-efficiency units. Lower numbers can be used for cheap units but should be checked by a voltmeter before use.

How good is 80 Plus Gold?

The 80 Plus Silver certification indicates that the power supply is rated for at least 85 percent efficiency at 20% load, 88 percent efficiency at 50% load, and 85 percent efficiency at 100% load. The 80 Plus Gold certification indicates that the power supply is rated for at least 87 percent efficiency at 20% load, 90 percent efficiency at 50% load, and 87 percent efficiency at 100% load. These are very high ratings - far in excess of what most power supplies achieve.

80 PLUS is a nonprofit organization that tests and certifies power supplies. Its logo is marked on power supplies that meet or exceed its standards. An "80 PLUS" label means that you can trust that this power supply will deliver cutting-edge technology with minimal impact on the environment.

High efficiency is important for power supplies to be environmentally friendly. It reduces energy consumption and lowers greenhouse gas emissions. Also, fewer high quality power supplies are discarded into landfill sites because they aren't efficient enough to warrant consumer purchase.

Features such as low noise, modular design, and eco modes (such as green mode) are also advantages of high efficiency power supplies. Low noise power supplies use less electrical current than noisy power supplies, so there is less risk of electronic noise causing interference with other components on your board. Modular designs allow you to remove and replace modules when needed. This is useful if one module fails and you want to replace it without replacing the entire power supply.
