An intel celeron e3300 in a zotac g45 itx mobo. I also have a blu ray drive and 7200 rpm 500gb HDD in the system. I ordered this on newegg:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817371029

but i am now reconsidering since the really long cables and bulky mesh on them might be to much for my small itx case (lian li pc qo7). I could cancel the order and get this:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817170018
but i am not sure of logisys quality. There is also a diablotek psu with the same wattage as the logisys one, but again im not sure of the quality again. I need responses quickly so i dont miss out on the chance to cancel the order if i have too.

Oh and also is there a con to having more than 1 rail?

PS: I know this isnt exactly the question for this section but based on the urgency i needed a section a higher frequency of visitors.
 
Cheap PSUs are always a risk. I have build 4 machines in the last few years all with cheap PSUs 3 are fine (so far anyway) but 1 couldn't supply enough power (even though rated 700W and system needs around 400-500W) and I had to buy a decent one. There is also the risk of them dieing and frying your motherboard.
 
Logisys and Diablotek are both some of the worst PSUs made. They are likely to explode well below their claimed rating, and will probably kill other parts when they die, and may die for no apparent reason.
Consider this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16817104075&cm_re=FSP_300W-_-17-104-075-_-Product
which has a plate that will let it fit into the PC-Q07's standard ATX PSU space. Being smaller than a standard ATX PSU however, it will leave more space to stuff cables in that little case (or perhaps to mount an internal fan).
I've got my own mini-ITX build project underway, and have done a lot of research. PM for details if you like.
That PSU is a full 300W (HardwareSecrets got 345W out of it in load tests), and it is 80+ certified.
Your other choice is a modular PSU. There were some great deals available recently (like a 550W Truepower New for $40 after MIR), but they appear to have dried up. The cheapest one I'd consider buying on Newegg is $50 after MIR now: http://www.newegg.com/Product/Product.aspx?Item=N82E16817371016 or http://www.newegg.com/Product/Product.aspx?Item=N82E16817341022
 
I can also recommend the corsair power supply. I have one in my system and it's very reliable.


 
OCZ Fatal1ty OCZ550FTY 550W ATX12V v2.2 $49.99 after rebate

I have one of these and its been running non stop for months now its very quiet and has plenty of power. The nice thing about this unit is that its modular so all those unwanted cables can just be stored in its little OCZ case they give you. The Corsair CX400 is a great unit too, but the cables are not modular and you will have the same problem as the Antec unit you got.
 
Odd, that's the same OCZ PSU I linked, but our URLs are clearly different. But yeah, that one is decent if you want the modular cables (which I suspect you do; my PC-Q08 arrived just today, and it's larger than the PC-Q07 but I'll be glad during tomorrow's build that I got a modular PSU).
