Spire Jewel Black 650 W and 750 W: Spire added the phrase, “80 PLUS Bronze compliant,” on their website, a very smooth way to deceive users, since the manufacturer is not saying that the power supply “has” certification but that the power supply is “compliant.” The joke is that we tested this 650 W power supply and it could only deliver up to 550 W. Spire removed the offending phrase after they read this article. These power supplies are rebranded Seventeam ST-550P-AF and ST-650P-AF units, respectively, so they carry a fake wattage.
