EVGA SuperNOVA 2000 G1+ The EVGA SuperNOVA G1+ Power Supplies have arrived. Launched in May 2014, the EVGA SuperNOVA G1 power supplies have been among the longest-lasting and best-performing power supplies on the market. Despite only a few changes over the years, it's only fitting that these are due for an upgrade. Enter the G1+, the new and improved fully-modular power supply line-up from EVGA with an 80+ Gold Efficiency rating. Compared to the EVGA SuperNOVA G1 power supplies, the G1+ are up to 20mm shorter, feature 100% Japanese capacitors, are up to 20% quieter, have much tighter 12v. load regulation, and have a superior fluid-dynamic bearing fan.
