PSU advice needed for gaming ITX Rig

[pbrain]

hello, i'm building a very small micro-ITX, portable gaming system. here's the specs so far...

Zotac 9300 ITX @ 300 FSB, 4Gb (2x2Gb) Corsair Dominator @ 1200 Mhz & E5300 @ 3.9 Ghz

GT 9800 Green graphics card (i really wanted to use a GTX 460 Razor - single slot )

No CD or DVD drive and a single 1.5 or 2TB 3.5" HDD (i use Steam for gaming)

I've bought a fantastically small ITX case, the only problem is...it has a micro-ATX PSU of 250W at the moment.

The best replacements i've seen so far are...

Be Quiet 350W micro-ATX

or

Colours IT 500W micro-ATX

http://www.scan.co.uk/products/500w-colours-it-micro-atx-80mm-thermal-controlled-cooling-fan-24plus4-pin-m-b-connector

The 'Be Quiet' is rated at 350W, yet has a 12v of 30A total, looks a better build.

The 'Colours IT' is rated at 500W, but only has a 12v of 27A total!

...as you can see the CPU & MB is overclocked & i'm hoping to overclock the 9800GT Green GPU as well.

will any of these PSU's be OK? i've no idea on these manufacturers, i normally use Enermax or Corsair PSU's, but they don't do micro-ATX type as far as i know.

many thanks

sorry to bump, i really need to know which one (if any) is suitable for this project.

I've no idea about the quality of these PSU's.
