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

I have tried the IBM 2980s server PSUs,  They say that they are Platinum rated but they ended up being less efficient than my ATX PSUs running the same cubes. Also the IBM 2980s were so loud that you could rear them outside with the doors and windows shut. Literally people asked me what that noise was. Also they needed the fans as they run hot. So I sold them. I strongly recommend whether you go with a server or ATX PSUs you go with go with at least Platinum or Titanium if you can find them. Then you should run them at about 50% to 60% of their rated capacity as there highest efficiency is around the 50% mark and fades from there. Running then at about 1/2 load also reduces stress on them and increases reliability. Better PSUs have better cables and connectors. I did see a post where the someone melted the PCI connectors on the 2980 Breakout boards. See my other post on PSUs I have some Rosewill Tachyon 1000 watt 80+ Platinum that have been running for over 12 months straight with 2 cubes on each and they have not had 1 connector go bad or burn, and their fans are not even running at about a 60% to 65% Load. See my other posting on PSUs. I am also working on putting together a Titanium Server PSU solution that will run at 96% if anyone else is interested.
