Introduction and Features
EVGA adds two excellent new PSUs to their SuperNOVA lineup.
Introduction
Back in March, EVGA announced the pending arrival of two new power supplies in their popular SuperNOVA line, the 750G2 and 850G2. Both new power supplies are 80Plus Gold certified and feature all modular cables, high-quality Japanese brand capacitors, a single high-power +12V rail, and a 140mm dual ball bearing cooling fan (with the ability to operate in silent, fan-less mode at low power levels). The 750G2 and 850G2 are also backed by a 10-year warranty (with registration). And last but not least, many PC PSU enthusiasts will be happy to know the new 750G2 and 850G2 are built on the successful Superflower Leadex Gold platform. Superflower is the same OEM that EVGA uses for several of their popular higher output, premium power supplies!
EVGA was founded in 1999 with headquarters in Brea, California. They continue to specialize in producing NVIDIA based graphics adapters and Intel based motherboards and keep expanding their PC power supply product line, which now includes fourteen models ranging from the high-end 1,500W NEX1500 Classified to the budget minded EVGA 430W power supply.

In this review we will be taking a detailed look at both the EVGA SuperNOVA 750G2 and 850G2 power supplies.
Here is what EVGA has to say about the new SuperNOVA G2 Gold PSUs: “Unleash the next generation in power with the EVGA SuperNOVA 850G2 and 750G2 Power Supplies. Based on the award winning G2 series Power Supplies from EVGA, these PSUs features 80 PLUS Gold rated efficiency, and clean, continuous power to every component. This provides improved efficiency for longer operation, less power consumption, reduced energy costs and minimal heat dissipation. The new ECO Thermal Control Fan System offers fan modes to provide zero fan noise during low load operations. Backed by a 10 year warranty and Japanese capacitor design, the EVGA SuperNOVA G2 is not only the right choice for your system today, it is also the best choice for your system tomorrow."

Testing Methodology
Establishing an accurate load is critical to testing and evaluating a PC power supply. PCPerspective’s power supply test bench can place a precise DC load on the PSU under test. Each power supply is tested under controlled, real-world conditions up to its maximum rated load (at 40ºC), using both 115 VAC and 240 VAC line voltage. Our current suite of tests includes:
• DC Load Regulation
• AC Ripple and Noise
• Efficiency
• Differential Temperature
• Noise
The EVGA SuperNOVA 750 G2 and 850 G2 Gold power supplies were evaluated on both features and performance. A full range of equipment was used to test the power supply under controlled load conditions.
• (2) CSI3710A Programmable DC load (+3.3V and +5V outputs)
• (4) CSI3711A Programmable DC load (+12V1, +12V2, +12V3, and +12V4)
• (2) 200W Precision resistor load bank (+12V5 and +12V6)
• Switchable precision resistor load bank (-12V and +5VSB)
• Agilent 34401A digital multimeter (Accuracy ±0.0035% vDC)
• Extech 380803 Power Analyzer (Accuracy ±0.5% of full scale)
• DS1M12 "StingRay" digital oscilloscope (20M S/s with 12 Bit ADC)
• Powerstat Variable Autotransformer, 1.4 KVA, 0-140 VAC
• Extech Model 407738 digital sound level meter (Accuracy ±1.5 dB)

The PSU

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?
