Advice on these PSUs with case

Ok, I've pretty much settled on the P182 for my case, but with that decision has come the worry that the PSU I've chosen may not fit, or at least might require me to remove the lower fan near the PSU bay.

The one I plan on getting is:

I also see this one:
http://www.newegg.com/product/product.aspx?item=N82E16817139002

The first one is 6.3" long and the second one is 5.9" long. They are both the same price (before rebates), but the first is 700W and the second is 620W.

My components will be:
Gigabyte GA-EX38-DS4 (or perhaps a similar Asus model)
E8400
8800GTS (G92)
2GB Kingston ValueRAM
XtremeGamer Soundcard
Seagate 500GB HDD (7200.11)
Asus optical drive

I think that's everything. So I'm assuming that either wattage is fine for this setup. 620W seems like enough, although 700W sounds safer, perhaps for future upgrades.

But I'm mostly worried about the length. Is there a "normal" PSU length? I know some are 7", and that's probably too long for this case without having to remove the fan.

Anyone have any experience with these PSUs, particularly with the P182?

Thanks.
 
The P182 is a pretty big case. I really doubt there are many power supplies that wouldn't fit.

I'd get the Corsair one if I were you, it's quieter and has a single 12V rail.

It has three 12V rails. Where do you get one? And why would that be better than the Thermaltake's four?
 
Well, I probably should have read more reviews first, but I just did that and several of them say it fits great in the P182! :)

It advertises 3, but it's really one. I read that here:

and here, another model in the same line which also advertises 3:

For some reason the one you linked to has some generic tips on PSUs in the item description instead of Corsair's usual description.

One is better, in theory, I've heard, because the 12V have a minimum power requirement (1 amp, or something), and with three or what not you have to balance the power between rails, to make sure you meet the minimum, and ideally to get equal power between them.

Something like that, I'm no expert but I've heard it from reputable sources.

The Corsair is quieter too, which you seem to care about if you're getting a P182.

Hmm, that's interesting! I'm going to choose that one anyway, but yet another reason! And yeah, quiet is nice. :)

EDIT: I checked that link. Are you sure you aren't looking at the Corsair CMPSU-650TX? That one is listed as having one 12V rail, but it's not the one I plan to get.

The HX620 is indeed a single rail unit, despite the way it's labelled (although for the average user this distinction is irrelevant), and would be a good choice.
