I just made my first computer though it turns out that the power supply(Thermaltake LitePower 600W) was too weak to turn on my build so am in need of a more powerful and better power supply.

I was thinking of either: -Corsair VS650 http://www.msy.com.au/product.jsp?productId=9919
-Antec VP-650P http://www.msy.com.au/product.jsp?productId=8640
-Antec EarthWatts EA-650-Green Watt PSU http://www.msy.com.au/product.jsp?productId=7680
-Thermaltake LitePower 700Watt PSU http://www.msy.com.au/product.jsp?productId=5106

My PC build:
Intel i5-3550
AsRock Z77-Extreme4-M
MSI R7870 Twin FrozrIII OC
G.Skill-NT 8GB Kit (4Gx2)
ASUS PCE-N15 Wireless-N Network card
Samsung SATA 22x Black DVD RW
Seagate 3.5” Barracuda 1TB
Thermaltake Dokker (Case)

I will also be using the PC for a lot of gaming so i just need suggestions on which PSU i should get

The TT lite600 should have powered that system. Its not a top notch PSU but the litepower can deliver its rated load.

Hi :) 

As said..it should easily have started (powered) the system... I suspect you need to look at another reason for it not starting... connections etc ?

All the best Brett :)

I'm quite certain it is the psu as it had powered my computer when i only had one 6pin pci connected to my graphics card. When I realised my mistake i plugged in the second 6pin connector to my computer and it wouldn't turn on though all my fans and lights were working. I have read that Thermaltake has been known to actually deliver less watts than what is advertised. I also checked online and found that other people had similar issues and the problem was the psu.

Not surprising that a Litepower 600W wasn't strong enough for your system as I think it is highly unlikely that it is high quality.

Your system doesn't require any more than a high quality 450W PSU with two PCIe connectors. So I would actually recommend the Antec Truepower New TP-550

As it is a step above all the listed options in terms of quality and performance, only ~$5 more expensive and it is more than enough for your build.

If it has to be one of the four you've listed then I would prioritise one of the other Antecs. The Antec Earthwatts EA-650 Green is probably just about worth the extra $6 over the Antec VP650P, even though the differences between them aren't great.
