Backplane of Silverstone RM43 requires TEN (10) Molex connectors...best PSU/adapter setup?

Insanity…but its what it needs. Whats the best way to power these? I dont think any PSU comes with nearly that amount. Any advice on a PSU/adapters needed? It would be ATX sized.

Thanks!

Are the ones I have used in the past

Thanks for this - on typical ATX PSUs that I’ve seen, there are PSU connectors that have a chain of 3 SATA connectors. Is it okay to use a MOLEX adapter on each one of those 3 connectors in the chain?

Yes just avoid using multiple splitters on one cable i’ve seen them burn out in this exact use case, If you stick 1 to 1 it will be okay.

I go the expensive route, and get a modular ATX supply, and a extra cable bundle.

Cable bundle of like £50 is not cheap…

But I ran a 24x HDD rig, and the throughput, was not small, so didnt wanna worry about melting extensions…

I can have a max of 20HDDs in this chassis. Which PSU did you go with?

Depends on the rest of the system.

I had dual GPU’s, and went for a 1000w, expecting a real sustained draw of 800w at load.

It peaked a bit higher, but nowhere near worrying about.

Another case, I have a 500w supply, for 20 odd drives, and a Threadripper, and a couple PCIe devices.
Probably only pull 350w? Maybe less even at idle.

Gotcha thank you kindly!

FYI, I went this route. Got a nice corsair 1000watt PSU and got extra peripheral cables.

The chassis backplane diagram is saying i should only connect one backplane per molex (I think) but that just sounds like overkill to me:

I use a single 4 pin molex for each EDIT: SET OF FOUR of the sata/SAS drives on my machine.

I needed 6 molex connectors, so I got a cable pack.

You should be fine

To clarify, the backplane does not REQUIRE all 10 Molex connectors to be used.

You only need to connect one Molex on each row (5) to the PSU. Each row has a pair of Molex’s so that they can be connected to both “optional” mini redundant PSU’s.

You’ll be fine running just the 5 connectors, provided your PSU give enough power along the rails being used.

Good first post, you’re gonna do alright here.

Indeed you don’t require all 10 power connections. Just be sure that you’re distributing the amperage in a balanced way and the wire gauge of your power cables is appropiate. You don’t want 20 hdds drawing from a single 20awg wire.
