EVGA’s new line of SFX PSUs


During the past year we have seen a lot of interest in the SFX small form-factor power supply market with more and more big-name power supply manufacturers adding new products on a regular basis. EVGA’s SuperNOVA GM Series includes three SFX form-factor power supplies: 450 GM (450W), 550 GM (550W) and 650 GM (650W). We will be taking a detailed look at the SuperNOVA 650 GM in this review.

All three SuperNOVA GM Series SFX power supplies are fully modular and certified to comply with the 80 Plus Gold criteria for high efficiency. The GM Series power supplies use a 92mm cooling fan that operates in silent fan-less mode (below 30% load) thanks to EVGA’s Auto ECO Mode fan speed control. The compact SFX chassis measures a mere 100mm deep and they all come backed by a 7-year warranty.
