Are any of these PSU's good for my PC? comes with SC2

[samk]

case: cooler master haf 932
cpu/mobo: i5 750/ asus p7p55d-e pro
gpu- gtx 460, sonic platinum 1 gb
ssd- vertex 2 e 120gb (or agility)
hdd- samsung f3
ram- 4gb (undecided on brand)
i plan on overclocking

I'm pretty sure I need 750W (do i need less, more?). Wanted to buy with starcraft 2 to save more money with a friend, who needs it and can get it tax free and split with them and pick it up in a few weeks when i see him.

1. Antec EarthWatts EA750 750W Continuous Power ATX12V version 2.3 SLI Certified CrossFire Ready 80 PLUS Certified Active PFC w/ SC2 for 149.98

3. XFX Black Edition P1-750B-CAG9 750W ATX12V v2.2 / ESP12V v2.91 SLI Ready CrossFire Ready 80 PLUS SILVER Certified Modular ... w/ SC2 for 139.98 (20MIR) *it says its fermi friendly and my gpu is fermi, just fyi

4. PC Power and Cooling Silencer Mk II PPCMK2S750 750W ATX12V v2.2 / EPS12V SLI Ready CrossFire Ready 80 PLUS SILVER Certified ... w/ SC2 for 179.98

The last two seem like the best deals since im essentially getting them for 45 dollars-50 dollars cheaper than if i bought them separately. or are those psu's too expensive and if so, what are my other alternatives?king.

All of them are excellent choices.. My personal recommendation goes to the XFX 750W.. Looks are out from the contemporary PSU designs and may not be to everyone's liking but its a Seasonic build and has excellent performance figures..

one problem i read with the review was that the pins were too short to ocnnect to mobo in a full tower case, if thats the case what sort of extendors should i get ?does it affect the PSU at all?

I'll second the XFX, the length of the 20/24 pin cable is only an issue with cases that have bottom mounted psu's it seems.
I'd recommend an 850 but I didn't see any with a combo deal w/SC2 on newegg.

For a single GTX460, you barely NEED 400Ws, so either one are overkill, but if you plan to SLI in the future, its a good investment.

They are not really that short for you to need any sort of extenders.. People try out various many routes to connect the pins for achieving a neat layout look which might be causing a length shortage.. I've read many reviews about them (have personnely used one for my friends build inside a CM Sniper) and none have suggested that anybody would be running out of cable length(s)..

+1 for the XFX 750.

Some really excellent reviews show you're getting your money's worth.

If you can find a 650W PSU with the same quality you'd be in good shape using it with your system and 2x GTX 460s (along with some overclocking and a few extra HDDs/SDD and etc)
