Power supply!!
So I ordered a 48v 12.5amp power supply off ebay that was listed as SE-600-48 which is the meanwell 12.5amp power supply. I received SCN-600-48 which is a 12amp power supply and listed as discontinued. The seller has offered to take it back and refund me shipping on sending it back as well as refund me the entirety of the listed price...
I want to know if a 12amp power supply will be good enough for 4 320oz +g540? Should I keep this power supply?
SCN-600-48 <-- this is what I received
SC-600-48 <-- this is what I ordered but apparently they don't have it.
I've seen ads for the scn-600-48 going for 200-750 bucks... but this is a discontinued product.
when using 115v it measures 55v at the terminals and 44v when on 230v. I unfortunately don't have a good enough volt meter to measure the amperage on this to see if it can really do 12amps. But given this... should I keep this power supply? and will it work on my G540?

Re: Power supply!!
So why does the cncrouterparts store offer a 12.5 amp power supply for the 4 axis setups? if the 7.3 amp supply works fine?
Re: Power supply!!
Just for the extra robust outputs. The PSU runs cooler and should last longer. Also, some of us just have no idea what we will hang on our machines next.

Re: Power supply!!
Here's the G540's true power requirement. Please read this post. http://www.cnczone.com/forums/gecko-...-owns-one.html
Gerry is correct the Gecko has an internal 7a fuse (it's a non-linear burning fuse). You have MORE than enough amps to run 4 motors with that power supply. The voltage should be adjusted to under 50v as the performance increase to justify going above that voltage generates more heat, for the G540 with only a marginal performance increase.
The Gecko's true power requirement is 10a at max amperage output. 12a will be fine for your system. Maximum amps are only required if all 4 motors are pulling max amperage which in a real world environment virtually never happens. The 12.5a power supply offered by vendors (myself included) is really to power add on components as well. Coolant pumps, or CNC active cooling systems are typical uses for this larger power supply.
