Cant I use both V1 and V2? Could I use it for 5v applications? I thought the hub had several power inputs?
there is a chance that a weaker rail could try to sink the power from a stronger rail. (similar to connecting two or more power supplies together) ther are most likely ways to acheive this, but i havent attempted it. and the price of getting the parts, and shipping invested in it, you might as well have the better supply.
Plus, if you dont tamper with your power supply, they most likely have warranties in case they do fail.
Earlier when I said "when in doubt, if you can afford a power supply recommended by RJ, go for it."
it was meant as a response to
Ok, now I'm running scared on power supplies. I know what I need as far as stats are concerned, but I definitely don't want to blow up my SS strings. While I don't want to spend more than I have to, I absolutely don't want to fry my light show over $20 either.
Understanding that any electronic component can (and ultimately will) fail, and knowing that even the best company out there will occasionally produce a dud, can anyone provide a positive list of manufacturers with a good track record.
...yes, I could spend a couple of hours online and come up with this.. and will if I have to, but I figure the collective brain power on this site is enough to build a space shuttle if we wanted to... so why repeat the effort if someone already knows the answers.
My understanding so far is, to calculate the AMPS you need for your strings... add on another 20% -ish then try to find a ATX power supply with a single 12v rail that can handle that.
if you have a high number of amps, then think about splitting them up over 2 or more hubs ( to distribute the power needed.) then you wont need as powerful of a supply.
for example, i ordered 4 SSC's, and 2 Hubs... if i split my ssc over the two hubs, i would only need (~4AMPS x 2 (SSC) = 8 + 20% equals about 9.6AMPS, or about 10 amps... so i could buy 2 cheap power supplies, than if i tried to put it all on one hub (then in this case, i'd need a 20A supply, not a big issue, but as power needs grow, splitting up into more than one hub makes sense.)
