computer power supply

tower computer left on, unit intermittently reboots and stops during post with flag" Power supply surge detected, unit stopped to prevent damage"

Is this really the psu or other possible cause?

Sounds like a typical PSU failure.    I would use a PSU tester or swap it out with another (for testing) ASAP.    The power surging can fry your motherboard along the way of failing.      I wouldn't turn it on again without running these test to verify it.

Try it in a different plug or thicker cable if the above test/swap isnt available.

A thicker cable solved the issue?   I've seen a thicker cable solve a PSU issue before, but never a surge issue.

"... Will aquire a Corsair HX1050 for this 6+ HDD box. " ==> WAY overkill.

Unless you're running a couple of high-end video cards, that's WAY too large a power supply.    Won't hurt anything to use it; but you'll be running far outside of its most efficient range [80+ PSU's aren't nearly as efficient below 20% or their rated output ... and it's VERY unlikely you'll be drawing 20% of that PSU's rated power].

I have a 20 hard drive server that runs quite nicely on a 650w unit ... and never draws over 200 watts.

BTW, I agree with tailordigital that Corsair makes excellent units EXCEPT for their low end CX series ... I'd stay away from those, as they aren't fully spec compliant and won't work with some motherboard/CPU combinations.
