Since the introduction of the 80 Plus certifications, we've seen a slow but steady trickle down effect where labels that were once reserved for the highest of the high-end (e.g. 80 Plus Gold) have eventually reached mainstream price points. Manufacturers including FSP, Rosewill, Sparkle, and SuperFlower now sell affordable 80 Plus Gold power supplies for less than 0. But if mainstream users are now able to get 80 Plus Gold, what should the high-end market offer? Enter 80 Plus Platinum:
Those looking for maximum efficiency can now set their sights on 80 Plus Platinum PSUs, which will be new halo market for high-end—and high cost—power supplies. To reach the necessary efficiency levels, some improvements are necessary that can change some of the core characteristics of a power. Improved resonant topologies, new MOSFETs for synchronous rectifying, higher switching frequencies, better drivers, and low-resistance conduction paths are just some of the things we'll see with 80 Plus Platinum. We're naturally eager to see what the new models can bring to the table, and Enermax sent us their Platimax 750W model, which uses an optimized Modu87+ design. Read on to find out if Enermax is the new efficiency king, and how it performs in other metrics.
NZXT is a well known provider of "eye-catching" cases and peripherals, but like many other brands they offer power supplies as well. These include the HALE90 series, their first 80 Plus Gold product to hit the market. While the HALE90 targets the high-end audience, NZXT also wants to cater to midrange users, and for that market they have their new HALE82 series that covers wattages from 650W to 850W. The rated output makes these models good for high-end single GPUs as well as moderate SLI and CrossFire systems. Features such as 80 Plus Bronze certification and modular cables are common these days, but such features say little about how good a PSU really is. Today, we're testing the 650W and 750W models, with our usual results on the following pages.
