One more question... This PSU seems to have 4 molex connectors. Each of the ss-500's require 2... I'm trying to build this box to be expandable to 15 drives eventually, so 3 5-in-3's... Can I power the SS-500 with SATA connectors? Is there such a thing as a SATA back to molex adapter?

 

Thanks again for all the help guys, I'll be glad to get this box up and running so I can contribute here and not just ask questions

 

Cheers,

Molex is pretty standard , even on today's power supplies, maybe not enough , but than there are 1 to 2 or 1 to 3 splitters like this.

and here's a little movie about the X-CASE SS500 ,, A direct clone of the Norco SS500, maybe the standard fans of the norco are more quiet?

 

 

I immediatly replaced the standard fans of the XCase Fans,  the exact db"s i could not find because of the no-name china fan,  but by my personal oppinion they where just on the edge of loud

I now have 17db Noctua's 80mm / 53m3/H without LN or ULN adapters and now it's a better balance between cooling and noise , but they are stil the loudest of the case. above the noise of the HDD's

 

With the LN adapter they get 11 Db with 39m3/h they are realy quiet, but then the temps reach 36 to 38 in normal operation with the case fulled with 5 green drives ( ambient 22 degrees)

calculating parity they can get 44 degrees. Now my CX430 is the loudest one.

 

Fantastic.. I'll add that fan to my order. Thanks for the tip.

 

I'm aware of the molex splitters.. I'm just concerned that it's not going to help much. I guess my thought is that if the SS-500 needs two power connectors, it needs the additional juice that a second connector would provide.. otherwise, wouldn't they just split a single connection inside the unit? How is a second molex connector off a splitter going to provide the same power as 2 independent connectors? If I end up with 3 of these, then the 5 SATA power connectors on the PSU are going to go unused and that seems like a waste.

 

I guess I can worry about that when it comes time to expand...

Compare it with your electrical installation at your home. No problems here to split them up.

 

Do you use power strips at your home? like this?

no special technic or rocket-science inside this thing. :-) just don't go over the maximum watt and Amps or else the cables melt or get really warm.

 

I dont' know how it is in the USA, but over here in my house i have 16 lines of 220volt 16A / max 3500watt per line.

 

I can virtually connect unlimited devices with this these power strips , just don't go over the maximum rated wattage per line.

 

haven't seen sata back to molex.

 

just enjoy , extend and get a decent single rail power supply.  1 line for  all of the available AMP's  

 

For the unused sata connector's : If that really bother's you, you can buy a modular power supply : only connect what you need, but you still need the molex splitters. ( in a normal ATX case is enough room to tie the unused cables together and give them a nice place so they don't interfere with the airflow.

There actually are SATA - Molex adapters, but you shouldn't need them.  The Norco SS-500's molex power ports are redundant, so you should only need to provide power to one of the ports, not both.  If you still need more molex connectors, then just use the monoprice splitters that Rembro linked.

Ahh... Thanks, that is a key piece of info. I shall split then. Is 500w enough for 15 drives (the max for the case)?

 

Thanks again guys... Ordering tomorrow.

common used model here are the Corsair CX500 you chose is 34 A single rail

 

http://www.newegg.com/Product/Product.aspx?Item=N82E16817139027&Tpk=cx500v2

 

maybe just on the edge for 15 drives, if they are all green maybe

 

play it save = CX600v2 = 40 A

 

http://www.newegg.com/Product/Product.aspx?Item=N82E16817139028&Tpk=cx600%20v2

 

or the TX650 V2 = 53A

Single socket H2 (LGA 1155) supports

    2nd Generation Core i3 & Intel®

    Pentium® family processors

 

oops I just looked and I have the 2100t can't test cause I have no ram yet. going of the supermicro website i3 seems to be supported

besides look at this post http://lime-technology.com/forum/index.php?topic=12956.0 poster is using the 2100t.

 

eather way once the ram comes in I will let you know if it works or not

 

I can confirm ot boots, sees the raid cards and that is as far as I have goten, got to eat. Will put the old unraid drives tell it to boot from usb get things set up and report back. BTW I had a stick of non ecc ram and tried it out while my ecc was in the mail was a no go. Ecc worked but there was a slight delay while the machine booted before it posted

So this build is cursed, or I'm just having a rash of bad luck with it.

 

I finally got everything put together last night (with the exception of the parts I'm still waiting on).  Being anxious to get everything up and running, I put everything in the case, plugged it all in, and.... nothing.  Well not quite nothing, everything turns on for about 2 seconds before turning off... then the cycle repeats until I power off the PSU.  Out of all the various systems I've built, I've never seen this happen before, though I suspect I have a short somewhere.  It really is my own fault for not testing everything before putting it in the case... but c'est la vie.

 

So now, when I get some free time this weekend, I'll tear it down and expose the culprit.  I do have pictures though for when the build is done, so there's always that.

Ugh!

 

I am just starting the third build with this board. I love them..

 

We are probably going to order a few for ESX testing at work.

 

try pulling the memory out and see what happens. you did get thermal sensing memory on a board that i dont believe supports it?

but you are right. it sounds like a short or bad power supply.

 

check for a stand off in a wrong spot or a lost screw under the the mobo?

 

I also had this happen with a third party build where the guy that assembled it ran wires under the mobo by the stand-offs. i guess he thought that was good wire management.  it ran fine at first, but eventually a soldered chip leg/pin punctured a power wire and did the exact same thing you described.

Yeah, I had actually changed the type of memory I got, but I guess I forgot to update my initial post.  I'm hoping to pull it apart tonight or sometime this weekend and see if I can find an issue.  As for running wires under the mobo, I've been doing that for years (though never power cables) and have never had an issue.  And we're talking systems that have been running for far longer than they should be.  Having said that though, I'll give everything a thorough check and see what I can find.

 

Thanks for the advice

Start with just reseating the RAM.  I've seen this behavior on my personal server, and it turned out that the RAM just wasn't seated quite right.  Sure got a lot of cursing out of me before I figured that out

Had to clear CMOS and do a battery pull.  Problem seems to be fixed now... now to finish the build

I'm having the same problem with the same build... I have removed the battery and cleared the CMOS... and it keeps just trying to start. Any thoughts?

It turns out it was the PSU. The Corsair CX600 doesn't work with this motherboard... go figure. Got a Thermaltake and it works perfectly.
