Need Help deciding PSU

Recently, the motherboard from my old Dell computer stopped working. I've decided to upgrade the system, replacing most of the old parts. Since this is my first time building a computer, I'm not sure which power supply to buy. Previously, my Dell PSU was 375W.
The items I'm buying include:

ASUS P7H55-M PRO LGA 1156 Intel H55 HDMI Micro ATX Intel Motherboard: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

G.SKILL 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Dual Channel Kit Desktop Memory Model F3-10666CL9D-4GBNQ: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Intel Core i5-750 Lynnfield 2.66GHz 8MB L3 Cache LGA 1156 95W Quad-Core Processor BX80605I5750: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

COOLER MASTER Elite 330 RC-330-KKN1-GP Black SECC ATX Mid Tower Computer Case: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Western Digital WD5000AAKS Caviar Blue Hard Drive - 500GB, 7200rpm, 16MB, SATA-300, OEM: http://www.tigerdirect.com/applications/SearchTools/ite...

I plan on using my old video card: EVGA GeForce GT220 1GB DDR2 http://www.tigerdirect.com/applications/SearchTools/ite...

I was thinking of buying this 430W power supply: http://www.tigerdirect.com/applications/searchtools/ite...

So will 430W be enough for this computer? Thank you in advance!

Should be, your graphics card isn't too meaty so i doubt it sucks much power. I have a 5770 on a 400w Corsair and it works fine, makes use of the 80 plus power efficiency :3

The issue isn't the wattage - 430W is enough. The issue is this power supply is just awful:

Bad/flaky PSUs are the cause of more than half of the hardware issues resolved here. PLEASE don't risk the rest of your rig with a psu like this.

If budget is a real issue, try this one:

Otherwise, quality 430W psus cost about as much as 5XXW psus, so my preference would be to recommend:

Oh just looked at the PSU you linked, yea I wouldn't go with that one. One of the only reasons that I can run all my gear on my 400w is that its quality :3 Get a Corsair or the SeaSonic that Twoboxer has linked.

Any time your looking at buying a PSU and you see that little red voltage select switch, PASS ON IT. Old design that isn't worth the money you'd spend on it. The FX-60, 8800GT, and even the Celeron 300A all have their place in history, its about time these PSUs do the same.
