After trying out 3 different PSU's (1KW, 750W and even an old under-spec 500W) I'm faced with the stark choices of either graphics card or motherboard is bad.

It's bizarre as the Titan works 90% of the time, the PSU's all work ok under load, and the old 7950 works under load on all PSU's, which points to the motherboard being fine. Looks like I'll be calling Asus for an RMA.

Oh, and the SSD cache cards are hybrid controllers - these things. http://www.amazon.com/exec/obidos/ASIN/B00BUC3NNS

From the looks of it, both your card and motherboard are probably fine. What's not fine is those weird no-name raid controllers that plug into your PCI-E and are probably screwing with them. What happens if you remove them? Is then everything stable without jumping through hoops?

Also, why would you even need them? You have a lot of SAS drives that would otherwise go unused? Isn't it much better and faster (but probably not cheaper, although haven't done the maths so not entirely sure) to just have the system on SSDs and everything else on HDDs instead of trying to shoehorn SSDs and HDDs into working together in some weird frankensteinian setup? The "hybrid" SSD/HDD combo drives are not hugely popular for a reason (that usually being not enough improvement in speed for not enough savings).

Just my (half-informed) opinion, though, so no offence :)

Oh I've tried both with and without the hybrid cards. OS itself lives on a pair of 840 Pro SSD's in RAID 0, theres a RAID 1 of HDD's for data, a 3Tb hybrid for games, another 3Tb hybrid for my "work" OS install, and another 3Tb hybrid that my VM's live on. Because they are hot-plug those cards make it very handy for switching between test and production drive sets (a long long and boring story, I have to deliver "work" on very specific hard drives)

As for the Titan not working 100%, I've tried different PSU's and still running into problems. On paper they all (apart from the 500W one) are above minimum requirements - but they are not exactly new units. Just in case, I've ordered a 1.6Kw PSU that ought to be able to supply enough juice. http://www.newegg.com/Product/Product.aspx?Item=N82E16817494006

Once upon a time, I started getting crashes in skyrim with my titan. One day everything was fine, the next all went to hell.At the end of the day, I couldn't even run the game. Other than that, I also had some very slight and hard to notice glitches here and there. Took out the 1.05 KW PSU I had and replaced it with a different manufacturer 1 KW. Everything running fine ever since. And the old 1.05 KW PSU went into a different PC that's not much "weaker" than the one it was taken out of except for a different, much weaker display card and is also working perfectly fine 24/7 and during renders (I do 3D). And that PC has something like 7 or 8 HDDs in it that are never off.

TL/DR;
Very good idea to change the PSU, especially an overkill one like that. It may not be the most efficient way but it's very likely the right way.

Ok new PSU has arrived.

Let's see if 1600W will help my Titan out :)

Ok - for a PC power supply it's fairly large, and the cabling is quite awkward to install. Perfectly understandable when you consider the potential currents involved and the wires to carry them. Cables are a bit short though, and I don't even have a full tower case.

Even so, compared to the PSU's and UPS's I lug around at work, this thing is like something you get out of a kinder egg :)

Ok everything is settling in nicely. The new PSU seems to have solved the random hanging problem, which I can only put down to PSU ageing and the new card not liking the supply. Every single one of the old PSU's still checks out fine though.

I think I'm at the limit of my CPU - but a bit more tweakage is possible, especially with my RAM. I got to a sweet spot the old 7950 liked, but the Titan doesn't seem to like the same values. Back to the BIOS I suppose :)
