Seasonic M12D 850w whine/buzz - need a new power supply
Posted: Sun Jul 08, 2012 7:55 pm
Ok since I've installed a new system into my FT02, Asus P9X79 with 3930k overclocked to 4.4ghz with a Noctua NH-D14 Se2011 (has PWM fans)
I've been hearing this whine buzz under full load, rendering and Prime from a metre away, which can be heard over the fans at low speeds.
I traced it back to the power supply - putting my ear next to the intake reveals a low frequency roar from the fan and whiney/buzz
So I now need a new power supply, that has less roar, and no whine/buzz under heavy load!
I guess one of the ones that stays silent until 400-500w?
Do you think a fanless 460-550w power supply is enough to run this system at 4.4-4.5 ghz? I have a GTX 570 as well
Both will run near full loads when rendering, as the GTX 570 uses CUDA to help render
other system specs - 16GB 1600mhz ram, 2 SSD, 2 internal HD, CDRW, 1 firewire pro sound interface, 1 PCI sound card, 1 PCI-E USB3.0 and Sata3 interface, and one fan controller
I may or may not add a 2nd GTX 570 in the future
