EVGA has launched a new line of small form factor power supplies under the SuperNOVA GM series. The new power supplies are available now in 450W, 550W, and 650W models all of which are rated at 80 PLUS Gold efficiency ratings with all Japanese capacitors and built in safety technologies for OCP, OVP, OTP, OPP< SCP, and UVP protections.
The single rail (up to 54.1A on the 12V rail) power supplies utilize Active PFC (power factor correction) and DC-to-DC conversion for the 3.3V and 5V supplies. EVGA’s SuperNOVA GM PSUs are all fully modular and support SLI with two 8-pin PCI-E connections on the 450W PSU and four 8-pin PCI-E power connectors on the 550W and 650W models. A single 92mm double ball bearing fan keeps the small form factor power supply cool while the Auto ECO mode keeps fan noise at a minimum with the fan spinning down completely up to 30% load, then ramping to ~18 dBA up to around 70% load and then ramping up to 37 dBA at 100% load (for the 650W power supply).
EVGA’s SuperNOVA GM SFX power supplies come with a 7+2 year warranty (7 year base warranty plus an additional two years for a limited time according to EVGA). The GM power supplies come with a AC power cable, PSU tester, and SFX-to-ATX adapter bracket.
The power supplies are available now for $109.99 for the 450W model, $119.99 for the 550W PSU, and $129.99 for the 650W power supply. Looking around online, pricing seems to be in line with the competition at these wattages, at least when considering the premium for the SFX small form factor designs.
