Choosing a PSU for large number of drives (not asking which, but HOW)

[aerospyke]

Hey all,

I'm not asking for help choosing a PSU, i'm asking for your thought processes in choosing a PSU. Not considering quality, efficiency etc etc... more the number of sata or molex plugs (depending if backplane or direct to drive power is used). Is looking at the number of plugs a consideration on those of you who have had to source a PSU requiring 6+ molex plugs for a large backplane, or 16+ sata plugs, or is a look for a modular system with enough peripherals outlets and get custom cables made so you can use enough of those outlets to get you 4 drives per outlet, instead of only half of them like most PSU's get you in the box?

Thanks

Seasonic + custom cables if you either don't have enough cables or the right lengths of cables is my vote. If it's good enough for satellite modems costing 100-200 grand, it's good for me.

There's discussion of this in the Power Supply Sizing post, I believe.

Proper Power Supply Sizing Guidance

I've seen about 1,000 threads like this one where people decide that they can power a dozen hard drives off a 360 watt supply. DO NOT DO THIS. I've seen another 1,000 threads where people decide to buy the cheapest power supply that they can find. DO NOT DO THIS. Your NAS lives or dies by...

Thanks, i've come to choose this PSU in this case.

Hopefully this all works well for me, as I expand the number of drives in the hotswap bays, i'll have to get some cablemod cables made to power more of the backplane...

awwww nuts, so the best I can find on the info on this chassis, is that it supports EEB... don't know if this is SSI EEB or just EEB, but my motherboard is E-ATX....... miiiiight be a deal breaker on the chassis. Does anyone have experience with this, not specifically this chassis, but the situation of the two formats, i'm going by what I understand that the mounting holes for EATX are EEB/SSI EEB are not the same and so may be an issue.

I think you may find that some holes will line up and some will not. You may want to install some additional stand-offs by drilling holes. You could tap these holes if the bottom plate is thick enough, or use nuts on the bottom (if space permits). Youtube has videos.

This thread has some people saying this case is not great, by the way:

Moving to a new case and I bought the wrong cables and learnt a lesson in the process

So recently I decided its time to get rid of my 12 bay tower case that is sitting at the bottom of my server rack and complete my setup to all rack based cases. So I bought the TGC-4824 24 bay rack mount case: http://www.anyware.com.au/tgc-4824.html Not a bad case, definetly on the cheap side...

Thanks Truejack, that's what I seem to find... or not find... much in the way of hardware in the AUS. The thread you send had a reference to a silverstone case that a) can't find, and b) the replacement, RM-43 is close to supermicro chassies prices from ebay... which I can't afford. This project has a budget that seems to want to have 20% taken by the chassis alone. I will keep hunting for a better deal but I'd like to get this project completed sometime in my lifetime.... and a chassis that requires 10x molex to power is a complete PITA.

I’d vote for a used SuperMicro chassis instead. They offer very large titanium rated power supplies to go with it and they’re redundant too. See 846 and like models.

Thanks everyone. I ended up finding a not ridiculous price on an CSE-846 chassis so this sorted out the PSU problem. Cheers
