Hot Test Results (~45°C Ambient Temperature)
The Enermax Revolution D.F. X 1050 has its output specified for an ambient temperature of 40°C. Generally, PC power supply units (PSUs) are categorized based on their temperature ratings, with 40°C typically associated with low-end to entry-level mainstream units, and 50°C designated for quality mid-tier to high-performance products. The 40°C rating of the Enermax Revolution D.F. X 1050 is disquieting for a product of such a class but the rating alone does not warrant poor high temperature performance.
The performance of PC power supply units (PSUs) is known to vary with ambient temperature, with the degree of variation largely dependent on the design and quality of the unit. In the case of the Enermax Revolution D.F. X 1050 PSU, the energy conversion efficiency exhibits a marginal drop of 0.3-0.4% at low loads, a range that is within acceptable limits. However, as the load increases, the efficiency decrement escalates to higher than 1%, indicating a different efficiency behavior under heavy load conditions compared to low load scenarios. This pattern suggests that the thermal stress on the active components becomes more pronounced as the unit is subjected to higher loads, reflecting on the design characteristics of the Enermax Revolution D.F. X 1050.
Under adverse environmental conditions, the fan within the Enermax Revolution D.F. X 1050 PSU begins its operation almost immediately after the load surpasses 50 Watts. The fan's activity progressively escalates, reaching its apex once the load surpasses 800 Watts. Beyond this point, the temperatures tend to elevate to a somewhat uncomfortable level, indicating a threshold at the platform’s design capacity and capabilities.

12HPWR plug from ATX3.0 is known flawed in design. It cannot sustain spec'd rating. Any chance the supplied one is actually the replacement newer 12V-2x6 plug from ATX3.1 instead?evanh - Thursday, November 9, 2023 - link
And if not already a 12V-2x6 cable set, do they plan to offer free replacements when they are available?jonnyGURU - Monday, December 4, 2023 - link
"12V-2x6" "cable set" is not a thing.Samus - Thursday, November 9, 2023 - link
I wouldn't say that. I haven't had any trouble with the 12HPRW connector, though I run a 4080 not a 4090.evanh - Friday, November 10, 2023 - link
Don't expect that to last. The plug is poor design.E.Fyll - Friday, November 10, 2023 - link
12VHPWR and 12V-2x6 cables are identical. Only the connector on the equipment's side changes and only the length of the Sense pins.evanh - Friday, November 10, 2023 - link
Yep, and the power pins in the plug are a whole new design to correctly handle high currents.E.Fyll - Friday, November 10, 2023 - link
Not at all. As I said, they are identical.evanh - Friday, November 10, 2023 - link
They are plug compatible for sure. Very much intended to fit the same socket. But the female pins inside the plugs are completely new.E.Fyll - Sunday, November 12, 2023 - link
I hate repeating myself but everything about the plugs and wires is identical, save for the length of the Sense pins on the equipment's side. The new connector only ensures that the PSU (if compatible) will not engage if the plug is not fully inserted, that's about all there is to it.
