Raidmax power supply

[mitch09]

Anyone used this brand. I have had terrible luck with my "cheaper" Rosewill power supplies from newegg. I am contemplating trying another brand.

Thats an even worse brand than Rosewill, imho.  My rosewill 630w has been solid for 3+ years now.

I highly recc. corsair, antec ... and on a budget I've had recent luck with EVGA ($39.99 on amazon for 500W) ... not sure that big enough for your needs.

Is the amp rating for the power supply only set form the single 12v rail. I know there are 3 other connectors of 5v on the board. If a power supply is rated at say 62A on the 12v+ rail and another 25A on the +5v can I safely use 50 amps on an active hub. I know general rule is 80%

I have several of the Rosewill RG630-S12 and they have also been rock solid.  No problems whatever and this is their 3rd year in my show.

No, use just use the single rail 12v rating for max amps only.  I always used no more than 80% of the figure.  You normally only hook up the ATX 14pin and 3 of the old style 12v molex power connectors ... everything else isn't typically used.  I always purchased only a PS which is 80 PLUS rated ... means its pretty efficient ... and also seems to infer a bit of quality also.  The junk supplies are rarely 80 plus rated.

If you act fast, you can grab an EVGA 750W for 40 bucks: You are not allowed to view links. Register or Login

I hope you acted slow.   That power supply has four 12 volt rails, with each rail only rated at 20A.  That is not a good solution for a DLA hub or Zeus which need to use single-rail power supplies.

Can you pick an output from each rail to plug into the hub to get around that?  So if the ATX plug is on rail one, use an output from each remaining rail for the 3 power pins on the hub/Zeus.

The first thing I checked was to see how many rails.

No, the hub and zeus boards have a single 12V plane, so they should only be connected to a power supply with a single 12V rail.  All connectors on the hub and zeus are connected together on the circuit board and plugging them into separate rails on a power supply could let the magic smoke out of the power supply.
