Introduction

We would like to thank EVGA for supplying the review sample.



The PSU market is of interest to many companies out there and EVGA is one of them. The company only offered one very high-end unit initially and released many PSUs to cover all market segments afterward—mainstream, mid, and high-end. The SuperNOVA G2 series is EVGA’s second-best series and until recently consisted of only two units we already reviewed, the G2-1300 and G2-1000. EVGA apparently also sought to establish a presence in the more popular market segment below 1 kW, which led to the release of the G2 850 W and G2 750 W. The units are also by Super Flower, as both are based on SF's high-end Leadex platform.

We have the G2-750 with Gold-certified efficiency on our test bench today. It utilizes a fully modular cabling design and gives the user the ability to switch between a semi-passive and normal operation where the fan is constantly engaged, although its speed is thermally controlled. While we aren't huge fans of semi-passive PSUs because the state puts a ton of stress on such sensitive components as electrolytic caps without offering much in terms of noise reduction, enough users with incredibly sensitive hearing will prefer it. The strongest points of the G2-750 are probably its very good price and the huge warranty of ten years! EVGA is the first company with the guts to offer such a long warranty with a PSU product, and we congratulate them for it. They must be really confident in the platform to have struck such a decision, or SF backed them up on it. However, Super Flower actually only offers five years with their products, so we believe EVGA to probably be on its own after five years.

Specifications

The unit is 80 Plus Gold certified, fully modular, and Haswell ready. The maximum operating temperature at which it can deliver its full power continuously is 50°C, which is in line with the ATX specification, and it includes all standard protection features except for OTP (Over Temperature Protection), which should normally be available in a high-end PSU.

Instead of the higher quality fluid-dynamic-bearing fan that equips its more expensive Super Flower Leadex Gold 750 W sibling, the G2-750 only comes with a double-ball-bearing fan. The G2-750 W still comes with the option to switch to a semi-passive operation and the for a 750 W unit large dimensions. Its price is very good for the specifications, and the warranty is ten years long, which is incredible.

The single +12V rail can deliver the unit's full power when needed, so it will easily support two high-end VGAs. The minor rails are also strong enough, and the 5VSB rail is a little stronger than the average, and we noticed the strange discrepancy that the mid-capacity Super Flower platforms feature stronger minor and 5VSB rails than the high-capacity units of the series. The SF Leadex Platinum 1200 W we reviewed a while ago had 100 W maximum combined power on its minor rails and only 2.5 A maximum current output on its 5VSB rail; it should definitely be the other way around!

Cables & Connectors, Power Distribution

Two EPS and four PCIe connectors equip this unit. We would, if they were to ask us, propose six PCIe connectors since 750 W could easily feed three mid-level VGAs and some users may go that route. However, those of you going for two high-end VGAs won't need more PCIe connectors as the unit isn't strong enough for more. With the main 24-pin ATX cable 600 mm long and both EPS cables close to 700 mm long, overall cable length is adequate in even very large cases, and the distance between connectors is good. All connectors also use standard AWG18 gauges.

We have nothing to comment on when it comes to the PSU's power distribution because it features a single +12V rail.

Packaging

The PSU comes in a black box with a top carrying handle that helps in moving it around. On the front are the series description, the model number, and the 80 Plus Gold badge in the bottom-left corner.


EVGA's logo is on one of two sides, and EVAGA's usual #1 mention is on the other. The company definitely has a strong tradition in VGAs, but they still have some distance to cover until they establish themselves as a solid name for PSUs, and one that can meet other well-established PSU companies eye to eye. But EVGA is definitely on the right track since most of their products are made by Super Flower and offer high price/performance ratios and hefty warranties.


The only interesting mention on top of the box is the label with the unit's model number, PN, and SN.


On the rear of the box are two lists - one of the PSU's features and the other of its cables. There is also a graph that shows the fan's operation in ECO mode (semi-passive mode) and a power specifications table. Here, you will also find three photos of the product; these include an internal picture of the unit with its Japanese bulk caps exposed.

Contents

As per usual for an EVGA product, the contents are nicely arranged, and the PSU is fully protected by packing foam and comes inside a cool black bag with EVGA's logo on it in golden font.


In the bundle is a pouch for storing all unused modular cables, an AC power cord, a set of fixing bolts, several Velcro-straps, and an ATX-bridging plug for jump-starting the PSU without a mobo; a very thoughtful addition since it can come in handy (e.g. leak-testing a water-cooling setup).
