As we approach the limit of how much juice power supplies can realistically pull from the wall, PSU makers are turning their attention to other differentiating factors, like efficiency. Zalman is one such company taking this approach, and has just unveiled its new ZM1250 Platinum "extreme efficiency" power supply. As the name implies, the 1,250W PSU is 80 Plus Platinum certified, partially the result of using high quality components like 105C solid capacitors.
Zalman claims it's also using a powerful and highly reliable DC-DC module in its latest PSU, along with a full bridge and LLC resonant circuits. If you don't have a degree in electrical engineering, you can read a detailed explainer on LLC resonant topology at EETimes.
The ZM1250 Platinum is equipped with a 140mm fan, flat modular cables (save for the main cables, which are permanently attached), and a dual +12V rail design with 45A available on +12V1 and 65A on +12V2. That's enough to support 4-way SLI and CrossFire configurations
This one's a bit of challenge to find stateside at the moment, but if you do find a unit, expect to pay north of $300.
