Perhaps you should consider either the Seasonic X-760 or the OEM (rebadged) version of it, the Corsair Pro Gold AX750
I'd love to but unfortunately they are a bit over budget. Thats why I said "near silent"
I should have mentioned I'm trying to keep my purchase to around AU$150 (~US$158)
The Seasonic X-760 is $230 and the Corsair PG AX750 is $220 here. The TP-750 and the Strider 750 are only $140
. The TP-750 gets good reviews here, but I cant find a review on the fan noise for the Strider.
I have ~500rpm 120mm case fans and a Megahalems with 140mm vortex fan @~500rpm, plus my HD6950 DCII has two 80mm almost silent fans (which I cant hear at idle @ 1m) . So The PSU just has to be quieter than those at idle, fan down in an R3 case.
