I have about 300$ to spend.

Will prefer full modular.

In Australia, computer specs in SIG.

I'm thinking of the Cooler Master V700 / V850/ V1000.

You already picked the V700 you wont find many other units that are better for the price

FSP Aurum Pro is also worth looking at but that series only starts at 850 watts

XFX Black Edition 750W (rebrand Seasonic X series) might be within range of that but I don't think they sell in Australia. Corsair AX760 is another rebrand of Seasonic X series.

edit:
on pccasegear and http://www.cplonline.com.au
$219.00 Cooler Master V700 (X series)
$229.00 Seasonic X-750 (X series)
$239.00 Seasonic XP-760 (X series Platinum)
$259.00 Corsair AX760 (X series platinum, pricey: same price as EVGA SuperNOVA 1000W G2...)

on PLE computers
$189.00 XFX XTR Black Edition 750W (rebrand G series, not the X series)

http://www.msy.com.au is supposed to be a big retailer but they have a terrible site.
