Differential Temperature and Noise Levels
To simulate real world operation, some of the warm exhaust air from the PSUs under test were recirculated back to the intake through a passive air duct, which allows the PSU air inlet temperature to increase with load, just like it would in a real PC.
The differential temperature across the power supplies were calculated by subtracting the internal case air temperature (T in) from the temperature of the warm exhaust air flowing out the back of the power supply (T out).
Thermocouples were placed at the air inlet and exhaust outlet. The ambient room air temperature was 23ºC (74ºF) +/- 0.5ºC during testing.
T out = temperature of air exhausting from power supply
T in = temperature of air entering power supply
Delta T = T out – T in
Sound pressure level readings were taken 3’ away from the rear of the case in an otherwise quiet room. The ambient noise level was ~28 dBA.
Note: Both EVGA SuperNOVA power supplies were tested with the ECO Intelligent Thermal Control System switched ON (enabling fan-less operation at low to mid power levels).

*Fan not rotating
With the ECO Intelligent Thermal Control System engaged, both PSUs operated in silent, fan-less mode at low to mid power levels. Once the cooling fan did start to spin the noise was noticeable but not loud. At full load the 850 G2 PSU cooling fan kicked into high speed and although I was not able to take a SPL reading, the fan noise was subjectively loud.

I was not able to take SPL measurements at the higher loads due to the background noise created by all the programmable DC load cooling fans running. At the low to mid power test loads I am able to catch a moment when all the load fans have cycled off to take a SPL reading of just the PSU fan.

The PSU modular connectors are shit. Typical plastic-to-plastic where you must apply humongous pressure so as to get it connected/disconnected (let alone when a couple of years have passed by, thus some heat and whatnot has been around – I expect it to break by then).
Also, the Sata cables would just not fit, so I’m stuck with a Molex-to-Sata adaptor, while I mail EVGA about it.
That’s unfortunate to hear.
That’s unfortunate to hear. The Super Flower branded Leadex Gold 750 has the best modular sockets and cables I’ve ever used. Certainly a pleasure to use after years with Seasonic’s horrible ‘death grip’ cables/sockets. The fit is firm and secure, but requires no excessive force. Same applies to the motherboard-end connectors, with the 24 pin one going in easily even on the first insertion. The SATA and 4-pin molex connectors are still fairly tight, but no worse than any others I’ve experienced (and that 4-pin molex is just a hideous, hideous design to begin with).
I had hoped that the G2 would be using the same connectors as the leadex, just without the LEDs, but it sounds like this isn’t the case.
That’s funny. I haven’t had
That’s funny. I haven’t had any issues with the cables or connectors. They’re super flexible, silicone even, and the “plastic shit” connectors make a good, solid, tight connection without having to do any forcing or any of that ridiculousness. I don’t expect them to break anytime in the lifespan of this PSU, not very easily anyway. The SATA power cables fit perfectly and weren’t difficult to connect what-so-ever.
Hi, I’m a bit of a newbie to
Hi, I’m a bit of a newbie to this, or I can’t read lol, but does this PSU come with a 4-pin molex power connector? (I will use it for the NZXT Hue+ which uses a 2-pin male molex connector for power). I will need it to have power directly from the PSU, so will I be able to do this straight out of the box?
