80 Plus White and Power Supplies – 80 Plus White, 80 Plus dry, bronze, gold, platinum

80 plus power supply

When you go to buy a power supply, one of the parameters that you should look at is undoubtedly its 80 Plus efficiency certification. We are used to seeing sources with 80 Plus Gold, Platinum certification but what is 80 Plus White certified ? Are the power supplies that carry it good? Let’s see it.

The 80 Plus certification is offered to products that have more than 80% energy efficiency in certain circumstances, in addition to a power factor of 0.9 or more at 100% of their nominal load. This certification, which has different levels, is granted to PC power supplies depending on their efficiency, so that at a glance we can know if they are good or bad, at least in terms of efficiency.

An 80 Plus White, or 80 Plus dry, efficiency certification is the lowest certificate a power supply can earn, but still meets the standard of providing over 80% energy efficiency under 20% load situations., 50% and 100% with a power factor of 0.9 or better.

In this case, an 80 Plus White labeled power supply guarantees a minimum of 80% efficiency when working at 115V voltages, and an efficiency of 82% to 20% load, 85% to 50% load and 82% to 100% load when working at 230V voltages (the one we use in Europe).

Just because 80 Plus White is the least of the 80 Plus certifications (it is below Bronze, Silver, Gold, Platinum and Titanium) does not necessarily mean that the power supply is bad, just that it is not one of the most efficient on the market, but it will always be above non-certified power supplies, especially OEMs.

For this reason, a source with an 80 Plus White label is usually synonymous with a reliable power supply with fairly decent performance, but with a price tag that is well below average. In other words, they are usually sources with good reliability and performance, at affordable prices, so they are not bad at all.

Of course, there is of course a whole list of power supplies with the best efficiency on the market, but not necessarily with better performance since there are many other factors to take into account when determining if a power supply is good or not.. If we have to rely solely on this certification, as we have said, they would be above the OEM, especially if they are from a renowned manufacturer.
