Corsair 430w good enough for this build?

Here is the link to the PSU. http://www.newegg.com/Product/Produc...r%20cx430%20v2

As a electronics tech, I am certain this will work, but the headroom doesnt seem all that much at load. My brothers system goes as follows.

AMD Phenom x3 2.3ghz 95w rated
ATI Radeon 4830 512mb
4GB Patriot DDR2
2 Sata HDD
1 Optical
1 120mm case fan

I know the 4830 is 150w max, however my 6870 is also and I know it takes up a lot more power. I'm estimating the 4830 being at around a true 80-110w max. Since the 12v rail puts out 336 watts, the CPU, RAM, GPU and HDD's takes up close to that amount. I already purchased the 430w PSU and it ships tomorrow, I just want to make sure this will work out fine. No overclocking is involved with him.

Thanks in advance for any ideas or reassurances.

95W + 110W + ~50W for the rest = ~255W. CX430 does have a pretty low rated +12V rail but it'd work just fine, plenty of people use that PSU with an i5 and 6850 or similar ~100W cpu + 6-pin GPU. In this review you can see the +12V rail is actually capable of up to the full 430W when pushed (though that is not a continous load). I wouldn't worry.

Yeah, wouldn't sweat that.

I'm running a X4 830 (@3.2), 8GB DDR3, 2 SSD's and a 6770 on that same PSU, with a few 120mm case fans and I've been running fine for months now.

So far so good on what i was reported. The 8-pin I think was for a CPU, and his mobo has a 4 pin connector, so I told him to connect 4 pins on that. Was that the right thing to do? I've never seen an 8-pin CPU connector.

I think an 8-pin CPU connector on a DDR2 board would be a rarity. I started seeing it on series-8 AMD DDR3 boards and any new board since.
