The Cooler Master V Platinum V2 1600W ATX 3.1 PSU Review: Quiet Giant

Hot Test Results (~45°C Ambient Temperature)

Inside our hotbox, the Cooler Master V Platinum 1600 V2 PSU exhibits a slight decrease in efficiency under heavy loads, with recorded figures of 89.2% at 115 VAC and 90.5% at 230 VAC, compared to 90.8% and 92.1% during cold testing. This reduction is moderate and not beyond our expectations for a quality PSU that is rated for continuous operation at ambient temperatures up to 50°C. Nonetheless, the PSU shows signs of thermal stress when the load exceeds 1400 Watts for prolonged periods.

The Cooler Master V Platinum 1600 V2 PSU's fan now activates earlier and accelerates more quickly compared to cooler environments, increasing almost linearly with the load. As the PSU nears 90% capacity, the fan reaches its maximum speed. This approach keeps noise levels acceptable up to around 50% load capacity, which corresponds to approximately 800 Watts. Beyond this threshold, the fan noise becomes noticeably louder, which is to be expected considering the massive amount of thermal energy/losses that need to be removed from the unit.

The Cooler Master V Platinum 1600 V2 PSU demonstrates a well-balanced cooling scheme, effectively managing acoustics and thermal performance. The internal temperatures remain consistently low without an overly aggressive fan profile that would lead to high noise levels prematurely. It is also important to note that the temperature of the primary side MOSFETs is low, suggesting that the either the heatsinks are oversized and/or that the anodized coating works.
