Gotta love Cnet and their crappy review...
POWER
Type: power supply
I am certain it would have been a lot of extra work to type in ATX Power Supply...
Which leaves us to assume... ASS U ME.. not good.
Even Asus fails to list what it is...
Power Supply
350 W Peak
So much for that... Assume ATX sized (standard) power supply.
If you want to measure the power supply you have right now, if it is ATX sized, it should measure:
150 × 86 × 140 mm (5.9 × 3.4 × 5.5 in)
