Received my Corsair CMPSU-550VX Friday; waiting for MB delivery on Monday. In the meantime, I plugged in an Antec PSU tester (the older model: http://www.amazon.com/gp/product/images/B00006B6U0/ ). The Green LED on the tester comes on, but using a VMM, when I test the +5V pin on the Antec tester, it first goes to 5.1V upon power on, but in about 5 seconds, drops to 3.67 V. Is this a bad sign for my brand new Corsair PSU? Or is there some sort of incompatibility between it and the Antec tester?
