Don’t worry about climbing to the top – a few years ago, powerful PSUs were low quality and lightweight, but that’s not the case anymore. If you go for modern gold or more, it will benefit from lighter weight regardless of its strength (which is a good thing). Intel has set some low-performance requirements for the ATX PSU Spec (v2.53), currently down to 70% efficiency and 10W (<500W) or maximum rated. 2%.
In addition to the low-performance requirements, the latest version of Intel includes some power supply run-time conditions that complement the other sleep model (ASM), allowing the system to wake up faster. Microsoft’s latest wait is an example of ASM. While there are no motherboards connected to ASM at the time of writing, don’t forget that PSUs can last for years and will be ready when ASM comes out.
