Psu what is 80 plus certified

All these are required to have at least a 0. It is more practical to achieve high efficiencies in high wattage supplies. The Gold, Platinum and titanium are thus more common in high wattage power supplies as compared to the standard desktop supplies. Click Here for our Current Statement Dismiss. Utility customer.

Currently, you'll hardly find any PSU on the market with the plain-old 80 PLUS certification, and usually the best efficiency-per-dollar score is delivered by Gold units.

The 80 PLUS Silver certification hasn't been very popular, because most manufacturers prefer to flog either the Bronze budget-minded or Gold premium-minded levels. Finally, the prices of Platinum-certified PSUs fell significantly once Titanium units made their appearance. Of course, the latter tend to be pricey at a given level of specs. Also, with Titanium, PF needs to be at least 0. In our opinion, the Titanium level is the most significant of the 80 PLUS certifications, because it's the first to take into account the efficiency under such a light load level.

However, given the power consumption levels of modern GPUs and CPUs especially under light loads, thanks to their advanced energy-saving features , it is imperative for a power supply to offer high efficiency at load levels that are only a fraction of its maximum rated capacity.

For redundant PSUs, which are usually used in data-center applications, there are five levels in total. As expected, the requirements at the next three load levels are higher. Nothing is ever perfect, and the 80 PLUS program is no different. It also has its deficiencies, which we would break down accordingly:. Because of the relatively low-cost premium and advantages they provide discussed below , we do not recommend anything less than 80 Plus, so make sure to look for this logo when shopping for your next PSU.

Most power supplies available today are at least 80 Plus rated. Over the past few years, efficiency ratings have expanded beyond 80 Plus to also include from least to most efficient Bronze, Silver, Gold, Platinum, and Titanium ratings. While Bronze, Silver, and Gold are becoming relatively common in most consumer PC builds, Platinum and Titanium ratings are generally reserved for either very high capacity PSUs used in workstation PCs where a few percentage points can make a big difference to the power draw , or server PSUs.

Refer to the chart below for an overview of minimum efficiencies for each rating at key loads. The higher the power draw, the more small changes in efficiency percentage will affect overall cost.
