Hi guys, I know little to nothing about computer builds but yet i find myself building my own lol
the one my friend helped me pick in my build was a - SeaSonic 560W ATX12V / EPS12V Power Supply -
but working out my money i wont have enough for that. Is there any cheaper ones that will fit my build ?

CPU - Intel Core i5-2500K 3.3GHz Quad-Core Processor
MOBO - Gigabyte GA-Z77-D3H ATX LGA1155 Motherboard
RAM - Corsair Vengeance 8GB (2 x 4GB) DDR3-1600 Memory
HDD - 1TB HDD ( part from old computer i was told i could use )
GPU - MSI GeForce GTX 560 Ti 1GB Video Card
CASE - Antec 900 Advanced Gaming Case
CD/DVD - LG GH24NS90 DVD/CD Writer
OS - Microsoft Windows 7 Home Premium SP1 (64-bit)

I have already bought the RAM and the Case.

Any suggestion would be REALLY helpful.
thanks in advance...

May I suggest: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

More than enough power for your machine and an insane deal right now for $22 after rebate. This is not cheap-o unit. If you're worried that you may upgrade your gpu later and need more power, at this price you can afford to buy a new one when you have the cash.

Another steal (I am not a Newegg shill) and closer to your original choice:

The Antec is also good (made by Delta), but for $5 more, I'd take the Seasonic.

430w would be running it too tight for my taste, 450w being the minimum recommended by NVidia, not a good idea though the price is pretty good.

The Seasonic is a good choice though.

I have a 2600k and a 560 448, so higher draw than the OPs proposed system, running on a 460w psu (a good Delta model). It never draws more than 300w from the wall, so maybe 270w from the psu. Manufacturers and calculators greatly overstate their power needs.
