Here is the PSU I am considering but something about it just doesn't feel right. I think it is the fact that it was once a $130 PSU and now I can get it for less than 1/2 of that. Also, the main connector says 20+4 pin, would that be an issue or is that the same as a normal 24 pin.

Just not a good PSU.

http://enthusiast.hardocp.com/article/2008..._power_supply/9

A 20+4pin fits a 24 pin motherboard just fine.

700 watts is overkill for your proposed setup. I highly doubt it will pull 250 watts loaded. If you are not going crossfire, you could even get by with a Corsair 400CX for $30 (was $20 after rebate last week), or spend a bit more for a 650watt unit if you want to futureproof yourself/go crossfire.

There are two brands out there where you don't have to worry about getting a turd, Seasonic and Corsair. Other brands make great PSUs as well, but not every PSU across their line is problem free. HardOCP, JonnyGuru, and Hardwaresecrets have the most trustworthy reviews. Also: http://www.overclockers.com/forums/showthread.php?t=589708

on computerxpds, I don't care if you said the exact same thing as dpunisher, its all good.

I may go crossfire in the future, so I do want to leave that option open and go with around 650W. Thanks for that link dpunisher, good info on the overclockers site. Something just didn't sit right with me about that PSU hence my post here.

In general, is there any performance issues with a 20+4 pin versus a 24 pin main connector?

Almost all PSU ATX connectors are 20+4 in order to work on older 20 pin motherboards. I really have not run across a pure 24 pin connector on a consumer powersupply yet.

I was unsure as well why computerxpds didn't post.

Looks like a decent PSU to me, 700 watts (prolly a lil overkill) but its modular which is a definete plus. Only 2 +12v rails, (I prefer 4 but thats personal preference nothing wrong with 2) but they put out a combined 50 amps, so you should have absolutly no issues with that. If you ask me, that looks like a good PSU for the money. Im not a big fan of MSI motherboards, have had nothing but trouble with them, however, for a MSI board, Thats prolly not their worst and it has some nice features. Other then that I see no problems.

There is no difference betweena pure 24 pin and a 20+4, and I do have a power supply at home that is a pure 24 pin. It is rare to find them with pure 24 pin, because of the lack of backward compatibility, but that is really the only difference, and even with a pure 24 pin, on some motherboards you can still connect it to a 20 pin if theres no capacitors in the way because it will hang out a bit. So, that won't be an issue.

Because it was exactly what you said and there is no reason for duplication on the forums.
