In most cases, when you try to improve something already good, many things can wrong, but thankfully, this wasn't the case for the new Corsair RMx range. Indeed the task's not easy since the existing RMx units only counted three years in production and delivered excellent performance along with dead silent operation. If you're still unsure on where to start when it comes to power supplies, don't sweat, we've tested dozens of PSUs, and handpicked our favorites, highlighting the sort of builds they should be in. Although there are no ASM compatible mainboards when writing these lines, PSUs last for many systems builds, but it is always worth being future-proofed. Microsoft's Modern Standby is an ASM example. Every new power supply meeting the ATX12V v2.53 spec has to be efficient at lighter loads, too.īesides the low-efficiency requirements, Intel's latest spec included some PSU timing requirements that address the Alternative Sleep Mode (ASM), the thing that allows the system's ultra-fast wake from sleep mode. Intel's set some low-load efficiency requirements with its newest ATX PSU spec (v2.53), with the bar now at 70% efficiency and 10W (<500W capacity), or 2% of its max-rated-capacity loads. If you select a modern Gold or higher efficiency PSU, it shouldn't have low efficiency at light loads, regardless of its capacity (which is good). Don't be worried about going over the top either-a few years ago, high-capacity PSUs were less efficient at lighter loads, but this isn't the case anymore.
