It's very hard to find this kind of PSU nowdays (except hunting down a used one), so you're lucky if you have one like this.  It should work great!
5*30 = 150 Watts (available)
49 ports *2.5 W = 122.5 Watts (required by 49 sticks)

all PSUs that have 25A on the 5V ATX (<-- !!!) will give you 125 Wats while 49 sticks require 122.5 (tiny difference, relatively speaking), so you need a REALLY GOOD PSU.
I have one that's been running 24/7 ever since I tested that 49 port hub from a British company (details somewhere on the USB hubs thread)

anyone know if there is an actual limit of usb devices per computer?   could I run 4 of these hubs connected to just 1 pc?

127 devices per USB controller including the hub etc. is the limit.

 so i could only run 2 hubs per pc?

no you can run 3 with around 39- 41 sticks each  acutally pretty nice as it will get you around the issue that most modern psu's will want to run only 40 to 44 sticks.

  I got 113 sticks  on 1 pc.

 careful hub planning is needed.  this would make things simple

Be careful USB also limits the number of chained decvices to 6 including the end device, any hubs, and the root hub (usb port on host).  Most USB hubs > 8 ports are actually multiple hubs chained together.

Sometimes old junk turns out to be a treasure.

The issue is that on modern PC the 5V rail really isn't used much.  Today almost all PC convert 100% of the power from AC to 12VDC.  Then whatever is needed on 5V and 3.3V rails is converted off the 12V rail.   99% of PC never use more than 10W on 5V rail so building massive 5V rails just means added cost for no benefit.

One thing to check is the wire gauge on your PSU ATX harness.  If it is really chip thin wires (the AWG should be stamped on the wire) it may not be able to handle a high current.

So can you find out if 3 of these will run on 1 PC? would be awesome! I am thinking 1 hub to 1 usb port, no daisy chaining these monsters:P

Someone will need to try.  Like I said no USB hub discloses the internal configuration so it will need some trial and error.  2 or 3 is probably fine it each one is directly connect to the PC.

 this reviewer is the best  and he reviewed the 1200 watt version which handles 150 watts max the 1000 watter will do the same.  these are discounted prices factory direct

 22 awg = melting

what gauge wire would suit?
Like most PC enthusiasts,  I have a ton of old hardware, including  PSU's... in the basement, in the attic, in the closet, in the garage, under the bed...

ALsO: I have an Antec EA-650 3 12V rails 22a,22a,24a I think, will that do it?

I know 18 gauge would be good. based on my gpu mining.

 maybe 20 gauge , but not in my house on my gear as I have 6 or 7 psus with  18 gauge.

I think the antec will run 40 sticks  not 49.  Most new psu's will not do the 49 sticks.  the rating is 125 watts on most and 49 sticks = 122.5 watts.

 for   safe running  you want 80%

Now I am glad that I kept my Antec True Power PS's. 

I have been using a True-380 for some blades and it has a 5v 35a rail. 

I have a new TP2-550EPS12v that has a 5v 40a rail.  This was a backup ps that I had for a few gamer machines that I had.  The receipt was still in the box.  $79.99 from Frys Las Vegas Apr 11 2006.  I always kept the paperwork and boxes in case of warranty returns.

Now they will both be put to use.

I have thermaltake smart 850, single rail:
Output Specification

AC INPUT Input Voltage: 100V-240V
 Input Current: 12A
 Frequency: 47Hz-63Hz
DC OUTPUT +3.3V +5V +12V -12V +5VSB
Max Output Current 25A 25A 70A 0.8A 3.0A
Max Output Power 130W 840W 9.6W 15W
Continuous Power 850W

better or worse? I am thinking that the goal is lowest wattage with highest amperage? forgive my stupidity, not an electrician, slept through shop and physics classes and way too many years ago anyways

I assume the +5v 130W is what philipma1957 refers to  saying ' most are 125W '

It is most wattage and amperage but ON THE 5V rail.

Watts = Current  * Voltage

The nameplate you posted shows 5V rail is rated for 25A max.
Watts = 25A * 5V
Watts = 125W

Your PSU is good for 125W on the 5V rail although you may want to back it off a little bit.  85% load would be 106W.

It is very rare for a modern PSU to have more than 125W (25A) on the 5V rail simply because almost no application needs more than half that.  Making a PSU have 250W on the 5V rail could be done it would just cost more for no benefit.

Whoa!, I just checked my basement/attic/garage/closet and look what I found:

this was an unintended purchase, PSU did not have correct mainboard connector that would fit a new build way, way, back. It is practically brand new:

so is this the one that will do it?

[DeathAndTaxes]

Yeah nice find.

Watts = Volts * Amps
Watts = 5 * 36
Watts = 180W peak
