The SuperNOVA 1000 G5 costs about the same as the similar-capacity G3 model that it is destined to replace in EVGA's portfolio. Unfortunately, its performance is not up to the G3 unit's levels and to make matters worse, the overall noise output exceeds 43 dB(A), so this is not the ideal power supply for silent operating systems. U.S. tariffs put an end to EVGA's close cooperation with Super Flower, so EVGA turned to FSP which is a good OEM with reliable products, but it cannot meet the performance levels of the Leadex platforms, used in the G3 models.

EVGA's 1000 G5 has acceptable performance, but the company's own G3 1000 is much quieter and more efficient for about the same price.



Traditionally all high-end G products were made by Super Flower, but this is not the first time that FSP provides platforms to EVGA, since the G1+ family is based on an FSP platform.

The main features of the G5 line, which consists of four members with capacities ranging from 650W to 1000W, are the following:

We will start the evaluation of the G5 family with the strongest member, which has 1000W max power. With only 150mm depth, the power density of the 1000 G5 is impressive. The power supply utilizes a fully modular cable design, and its external design is appealing. What matters the most though in a PSU, is the internals, but still many people want even the power supply to look good. 

* Not certified yet by Cybenetics. According to our measurements the PSU falls into this noise category. There is no efficiency (ETA) classification, because of the high vampire power which puts it off Cybenetics' charts.

A huge load of connectors is provided, including two EPS and eight PCIe along with twelve SATA connectors. All cables are long and it is nice to see them free from in-line caps. Not all are perfect though: the distance between the peripheral connectors is too small at 100mm and thicker, 16AWG, gauges should be used, on the cables that will have to handle increased loads (ATX, EPS and PCIe).

We strongly encourage you to have a look at our PSUs 101 article, which provides valuable information about PSUs and their operation, allowing you to understand better the components we're about to discuss.

This looks to be an upgraded version of the platform found in the EVGA G1+ models. The build quality is high, and all parts that FSP used are good and will easily outlive the provided warranty. Our only objection is the topology used on the primary side. Typically the Active Clamp Reset Forward (ACRF) topology cannot meet the performance of half-bridge and full-bridge topologies. Its primary assets are the long hold-up times with smaller bulk caps and the lower production cost because a smaller number of parts is required.

The transient filtering stage is complete and the NTC thermistor, which protects against large inrush currents, is supported by a bypass relay. Finally, the single bridge rectifier can handle up to 25 Amperes.

Usually, a 1000W PSU requires a bulk cap with at least 820uF capacity, to achieve a longer than 17ms hold-up time. Nevertheless, thanks to the ACRF topology the 1000 G5 manages this with a 560uF bulk cap, which of course costs less than a higher capacity one.

Cooling Misting Fan

On the secondary side, the +12V FETs are bolted on a small heat sink. A couple of VRMs is fed by the +12V rail and generates the minor rails.

The cooling fan measures 135mm across and uses a fluid dymanic bearing. It is a high-speed fan that is driven by an aggressive speed profile, so don't expect it to be quiet, especially under high loads and increased operating temperatures.
