chech this out, I just played crysis for say 10 min and as per HWmonitor the max +12V voltage was 5.19V. The game didn't crash nor did the PC itself. Also, as per my detailed PSU specs, I have 6, yes 6 +12V rails, so we don't know which rail's voltages are being displayed. I have had this PC for almost 2 years now and have have completed games like crysis, crysis warhead, COD 4 and 6 on the GTS 250 (a fairly nice card) on the same config except the GTX 570 without crashes instability in whatsoever form, so I highly doubt there is anything wrong with the PSU. What's your verdict on this ?
