You can save money by using any old USB Hub and old ATX PSU instead of
it's default power supply (even old 300 W PSU will give out at least 10 A which
is more than enough for 7 of any USB ASICs).
You should open it first and check if any Caps on the ATX PSU are leaking
and replace them or just don't use that PSU.
You just need to shorten BLACK and GREEN wires on ATX plug with a piece
of metal or copper wiring to give it a start and then solder RED Wire from any
Hard Drive / CD railing to 5 V on the HUB factory power supply jack and BLACK
(Ground) wire next to the red (one is enough) to GROUND on USB jack HUB side.
From what I've seen all those USB ASICS tend tend to pull more power
than factory declared values and then they get really hot and pull even more.
PS. IF you have a multimer you can check which wire in HUB Stock adapter
is 5V by setting it to 20 V and then putting one pin (any) inside the jack
and the other on metal around jack , set Multimer to 20 V and put the other end of multimer (+ and - , don't matter at this point) at the end of USB Hub PSU Jack wires (ground will show 0 V).5V is inside , ground is metal around iton all models I'seen so for but always check twice before soldering the cables.
3 usb Erupters and 1 U2 Antimer are all on one hub now and I don't see them
crying for power or getting too warm (adding some cooling on them , like a passive cooling used for N/S Bridge on old motherboards with a kitchen rubber or two is also not a bad idea).
Same thing can be done on AT PSU but you don't have to shorten GREEN and BLACK wires as they mostly start by themselves and have a build in switch
Just read 10A or more on +5V , open it and take make sure caps don't look blown) and you're good to go
Actually I was thinking to get my old HeatGun and some Cryoflux and go back to fixing all those old ATI cards with good MHash/s rate as their main flow is generally too much heat even when you don't overclok them so chips tend
to get too hot and actually desolder slightly from PCI-E card.
They still sell here for a hefty price due to litecoin mining.They will mine Litcoins
and I will mine the Litecoin miners
P.S. Forgot about shipping cost entirely tnx for the reminder , it would go
on top of import tax which can be anything from 20 to 50 % so no ebay or
amazon for me
