Question for ya all....
My Titan keeps causing my PSU's modular power connectors to eventually melt after like months and months of steady use. I think it may be because of crappy modular cable connectors n connections to the PSU.
The titan side of things - including the Y adapters remain in good shape.
So, Im wondering
Has anyone tried powering their Titans w/ one of these 2000w server PSU's using the breakout boards sold here on the forums to much success? Im just wondering if these breakout boards plus decent PCIe cables would be better for the Titan or not.
Looks like the controller board & pi would both have to still be powered by a seperate ATX psu to supply 5v ... is this ok to do?
Thanks

Not with a Titan but I have used them with nepturds.
I use 2 of them in current sharing mode per nepturd, I have 4kw rails!!!
I'm focused on redundancy and minimum(zero) downtime if there is a PSU failure.

I made my own connectors at first, then I got the breakout boards.

Theese are sold by user "Cablez".

Another reason I went with a 4kw rail is I wanted the PSUs to be at 1/2 of rated current for greatest efficiency.
The PSUs are great, can hot plug them if using more than one.
I also picked up some 1800w PSU's for backups. (same connector/breakout board etc.)
The only potential downside is 220VAC is required.
You also need a fan for the PSU, there is a fan connector on the breakout board.
I started with a 'poor mans 220VAC' in a 110VAC house by running extension cord for one of the 110VAC legs.
The gekkoscience.com breakout boards I bought also solve the 5VDC issue onboard.
He also sells 14AWG PCIe power pigtails to go along with them.
I bought some pigtails too, but never used them, as I soldered my 12AWG power wires directly to the ASIC PCB.
I used only 2 12AWG wires each direction and the wires get slightly warm but never hot.
Mine work well, I never heard of anyone having any issues but I did not look for such posts either.
Delivery was as advertised, no complaints from me!
I bought my PSU's on Ebay but he sells those too and the price is good.
2kw is a lot of juice to be exposed, think it thru. (12VoltsDC @ 166Amps = 2000 Watts)
YMMV
