Title: atx power supply breakout boards
Post by: taybrynn on February 03, 2016, 09:14:20 AM
(1) any idea when the next falcon ATX PS board buy might be?   Experiences using them?  What was your use of the Falcon ATX thus far?

(2) would a board like this: http://www.amazon.com/gp/product/B00V44UNXU?ref_=cm_cd_al_qh_dp_t
     make any sense at a cheaper alternative?   My thought is no, because it lacks the molex connectors and
     I'm unsure what size copper and what combination of input power is allowed.

Thoughts / comments on either would be appreciated.

Wow. At first glance that board looks pretty good.  Need to find out copper weight. But there are plenty of source connectors. The six and eight pin connectors have 3 and 4 12-volt wires each respectively.  I think that makes 18 12-Volt wires besides the two in the 24-pin connector.

The 4-pin hard drive connectors used on DLA and the Falcon only have one each. But the Falcon did have PCIE and other connectors which have more.

I am going to buy one to check it out.

I have just cut the ends off the power supplies and used terminal strips - with fuses in between and hard wired adapters to various items. 5V lines for the BBB or Pi... Just on the bench though. I use mean wells or other power supplies for the props and the show

Cool board and I almost bought one but it appears to have only 12v outputs.

If I'm buying an ATX breakout board, I think I would want both 12v and 5v outputs.

It had a 5V connector too. These days the majority of a power supplies power is in the 12V. Mainly to drive video cards and the like.

I agree it looked pretty interesting at first glance.  The description on amazon is a tad confusing, stating something about using
the 6pin "or" the 8pin connectors ... but it would be interesting to get some reviews of this board.

I was also debating whether to buy one to try out also, since its like $11.xx for amazon prime members ... and a decent bench PS
is always nice to have.

Ah ha.  It wasn't listed in the specs, but now I see it hidden there in the picture.

ATX 24P connector to 12V wire adapter
16 connectors for + or - wires (all 12v)
2 x 6 pin PCIE 12V connectors
3 x 8 pin EPS 12V connectors
1 x 8 pin PCIE 12V connector


I'm also guessing that little push-button is used to trigger the on/off logic in the power supply (with red led to show on/off status)

That's another place where it gets confusing and will need to be checked.  Is the 5V output, only the white header or is it the green terminal blocks.  The description states 16 connections for +/- (all 12V) which would indicate that the green terminal blocks are all 12V and the '5V' label may be for the white header.

If it checks out, it could be good.  The PCB looks a little thin compared to the Falcon ATX adapter.

One thing missing from this board is the big resistor to keep some kind of load on the power supply when the lights aren't on, so I wonder how well it will work with our kinds of load patterns.

I agree, I had some new ATX power supplies that would keep turning themselves off, if you didn't have a small load present all the time.
They worked fine with DLA active hub, but didn't work well with passive hubs or zeus boards.  Ironically one of these worked great with a zeus
board for some reason, but the others didn't.  I found the "auto off" (on no load) feature to be highly annoying.

The comment that concerned me a little was this bottom one:

Only need to connect it to the PSU 24 pin cable, and then turn on your power supply.

Can also connect 2 x 6 pin or 2 x 8 pin connectors.

And also, there are (3) 8 pin connects (not just 2) ... 2 are EPS 8pin and 1 is PCIE 8pin.

So I take this to mean
(1) connect the 24pin (minimum)
+ (2) optionally PCIE 8pin
+ (3) optionally EPS 8pin x 1or2
        OR
        optionally PCIE 6pin x 1or2

Most new PC power supplies you can jumper the green wire (3rd in from the side if I remember correctly) to a black with like the small loop of a paper clip, tape it up so it don't short out on something and your PS will never turn off

That is what I did with the last one I had to work on too Tony (though I did solder mine and seal with liquid tape since it would be in a box outside).

I got one of these today.   Soldering quality on them seems poor in a couple spots ... Wondering  if it's lead soldered cause it doesn't melt when I tried to reflow a couple spots.  Haven't hooked it up to anything yet.

Lead solder melts and flows better than non leaded.

Ain't that the truth.  take a close look at the board and make sure that it doesn't have a coating on it.

I meant  "lead free" ... Which I believe requires much higher temps.

Speaking of breakout boards, I stumbled upon another one on Amazon that was $12.99 + FS and meant to be used with the HP Proliant 800-1000w server power supplies.    The board plugs into the single HP hot swap connector and seems to provide over 80 amps at 12v.   The 1000w Proliant PS was only $18.50 ... And free shipping.   Would this make any sense to use on. Falcon f16v2 to power both 30a banks with plenty of excess amps to spare ... Or a bad idea ... I don't know what I don't know here.

These are good supplies and to get them new for that price is pretty cool.  You are not going to get that much kick out of a standard 12V supply for the price.  Those adapters you listed will make life much easier than attempting to solder wires directly to those pins (trust me on that).  These supplies also use the standard PC power plugs (unlike the HP supplies I have) which also makes them easier to connect to AC power.  Please keep in mind that while these power supplies can put out a lot of current, they will be drawing a lot of current to do it and will probably limit you to 2 of these per outlet (depending on how hard you drive them).  These supplies are not weather proof so make sure to keep them dry.

I have a couple of these along with a range of Dell supplies and I still keep using 350W units :), however if your looking for a single supply for a megatree then it would be hard to go past.

Note the supply is only 850W when used on 120v.

Thanks Phil .

The 69.9A should work pretty good at handling both 30A sides I would think.

I have NO problem with the $19 supplies ... other than the shipping costs.

I'd be curious if anyone has had any reliability issues with these or not.  Is the size
horrible?





Title: Re: atx power supply breakout boards

My only thought is a single connector may not be rated for 30A. May need to use more than one.

Well, and white these seem to have good reviews.  Many of reviews talk about a very high failure rate for these, some mentioning 75% failure rate ... which would explain the low cost.

David, which connector are you concerned with specifically?
Title: Re: atx power supply breakout boards
Post by: David Pitts on February 11, 2016, 05:39:27 PM
The terminals on the adapter board

These are Server supplies they will run forever.... however they also have really really really LOUD fans....

Need to double check but fairly certain the G5 versions are very compact and are half the width and same length as a 350w supply.

My only thought is a single connector may not be rated for 30A. May need to use more than one.

Soldering direct to the power supply output connectors can be done but you need a BIG iron, using the breakout board you will need to use multiple terminals for connections as it terminals on the breackout board look like 10A ones

Well, and white these seem to have good reviews.  Many of reviews talk about a very high failure rate for these, some mentioning 75% failure rate ... which would explain the low cost.

I find the failure rate astounding from the reviews.... more like they bought one then had no idea how to connect or use it

The description says its 11"x7"x6" which sounds to me like it won't fit in a CG1500.  But I like them and think they're very good supplies if you're willing to use bigger enclosures.
Title: Re: atx power supply breakout boards
Post by: taybrynn on February 11, 2016, 07:27:36 PM
Not using cg1500 personally but my Dad likes designing custom things and then building them ... Then mass producing as many as we need.    I'm more of a battery box person myself.   I've got. Lot of them, many oversize ones but they need additional blizzard proofing as I took on some snow this year.

Can anyone verify actual dimensions for one of these 1000w proliant power supplies?


11x7x6 seems a little doubtful to me


I can see 11" long, but is 7x6 accurate?
