DX-400WPS



12v rail 1    14A
12v rail 2    15A

So is that worth it for $9.95??

[taybrynn]

I don't think its the best match, unless you power requirements at like 12A or less for the entire hub.

Since each pixel strip is over 4 amps ... that $10 supply would only handle 3 strips.

I think it really depends on what you need and how much expansion you want to plan for.

The $40 Antec seems like a good value for the money.

[TheBanker]

Man, thought I found a good by....

[chrisatpsu]

If it SEEMS to good to be true...

it PROBABLY is....     

[taybrynn]

I updated the prices.  A lot of the deals have disappeared.  The $40 supply is out of stock.

Ironically the lower priced Rosewill is now $97, while the higher priced Rosewill (and higher powered)  stayed the same.

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.

Updated again.  There are a couple of deals right now on Corsair(s) ... discount codes listed.  And found a monster 104a supply
thats 80 PLUS GOLD rated for $204.

Almost all the SEASONIC units are very highly rated, but more expensive.

[chrisatpsu]

when in doubt, if you can afford a power supply recommended by RJ, go for it.

[taybrynn]

Chris,

Just to be clear, these are not RJ' recommendations, just some I picked out at various power and price points which are
all single rail 12v ATX.

RJ did recommend a Rosewill supply and another higher powered model which isn't sold anymore at Newegg. 

A couple of those Rosewill supplies are in the list, since that's what RJ used in 2010
on his megatree.

I think some of the Antec, Corsair choices are perhaps a notch up in Quality.

And then the Gold and Silver rated supplies are probably another notch up from those.

instead of using PC power supplies what about something like this? it's from Ray Wu's, the same distributor as the nodes/strips etc.

You could probably use it but you would need a kit 3 for each hub that you connect it to.  He is not clear on the specs but it looks like 3A of that power is wasted on the 5V supply that you would not be using.

[taybrynn]

For $48 (not counting shipping) and only 500W (and no amp rating) ... it doesn't seem to be a bargain, and its a no name brand.

RJ stressed you need to have a single rail and an amp rating  at 12V (to exceed your needs by 20% or more).

The $30 on my list would be similar and includes shipping.

[fjaust]

i ordered kit #3 anyway, just in case i can't find a reasonably priced ATX power supply. The specs say 5V @ 0.3A, unless i'm missing something?

with the shipping, if you are bundling them up with your light order anyway, then the cost will come down. 12V @ 500W = 41 amps, it might be enough for my usage because i'm not planning on using a huge amount of nodes, i'll have to work it all out.

i'll keep looking for a suitable ATX supply while i'm waiting for the co-op parts to show up.

[fjaust]

oh, and thanks for the list too by the way taybrynn, that will help
