mATX power supply recommendations?

Anyone have a quality mATX power supply that they recommend? I currently have a 320W Enermax EG320S and am looking for something more powerful. I checked Newegg, and they don't have much selection (and the ones they do have seem to be lacking in quality). Thanks.
 
If you're using an X-Qpack I found that a Corsair HX520W + Lite-On DVD writer fit properly with enough room for the cabling.
 
You can get even more space by using laptop optical drives (now available in SATA-flavor), as they're shallower yet.
 
Thanks for the suggestions so far, but my case requires a mATX power supply.

So, any mATX power supply recommendations?

What case do you have?

Anyway, out of all the mATX PSUs available at newegg, I only trust the ones made by FSP. Even then, I'd still be very very cautious with those mATX PSUs. Most mATX PSUs, at least the ones on newegg, are not good enough for gaming rigs. Meaning that they are either of low quality or have low amperage on the +12V rail.

However, this Seasonic PSU does look promising:
SeaSonic ECO 300 300W SFX12V PSU - $50

Comes with a bracket that allows it to fit into ATX and mATX case. It's actually a little smaller than mATX so shouldn't be any clearance issues. However it only has 22A on the +12V rail. A bit low but should be enough for most systems.
 
The 350Watt one on newegg has powered my main rig for a few months, closer to a year actually. It was a e2180 at 2.37 [the motherboard's fault] 4 sata drives, one ide, and 2 8500GT's. Contrary to what other people said about cheap power supplies it didn't die and put 120V through my computer, You just got to change the fan for something beefier if you're running as much as I was.

If you can afford the seasonic though, go for it, they might rate their psu's like pc-p&c.
 
Corsair TX 650W works great. Corsair also makes a highly rated VX 450W that works great.

If you want modular Corsair has some nice PSU units as well.

I highly recommend Corsair.

Wow 120v?? That is some bang-for-buck! Your computer still works, right? :p

No, re read the sentence It says it didn't, meaning it still powers a dothan 1.5GHz fine, could probably run a lot more still, even though I replaced the fan with a silent-ish fan...
 
Alright, I think I've narrowed it down to these two:

SeaSonic ECO 300 (thanks Danny Bui)
http://www.newegg.com/Product/Product.aspx?Item=N82E16817151058

Plus: 80mm fan, 5 year warranty, good review on spcr
Neg: only 300W


SeaSonic SS-350SFE (thanks lrwatson)
http://www.newegg.com/Product/Product.aspx?Item=N82E16817151063

Plus: 350W
Neg: no warranty? 60mm fan (not 80mm as on Newegg...the psu is only 64mm tall), no reviews


What do you folks think? Both are Seasonic and both are 80+ certified. Too bad Seasonic doesn't make an ECO 350. Below are the specs for my rig:

System Specs:
Athlon X2 3800+ AM2 @ 2.9ghz (290x10 @ 1.248V)
Biostar TF7025
2gb Crucial Ballistix @ 2.05V
WD SATA2 HD
Samsung SATA DVD-RW
SB Audigy 2 ZS
EVGA 8800GS
