My PSU just had a catastrophic failure (i.e. exploded)

I don't know from the original post if the four-year-old one was the "Kingwin", or if that is what was ordered, what "exploded" (or even what the actual question is), but from the later post of the amperage on a label, an average Kingwin is probably something like this one:

Note this anomaly they noted:

As promised, the above table shows the 12V rail distribution. What it doesn't show you is that several 12V rails were bridged by solder. 12V1 and 12V2 were combined to one big rail, as were 12V4 and 12V5. Yes, the PCI-E connectors get one big 70A monster rail, almost the whole 12V capacity of the unit.

It looks like that reviewed unit is plain designed stupid. In addition, it shows lots of voltage ripple at high loads, meaning that capacitors are operating near the max of their specs. Throw in cheap Chinese leaky capacitors and that's probably why the original xploded, capacitor plague failure, especially if it ran for a considerable time before dying.

Note that they use names like "Lazer", which would be a cool name in 1983.

Here's how you load balance a power supply.

Step 1: Sell the multi rail PSU on eBay
Step 2: Buy a single rail power supply
Step 3:
Step 4: Profit.

Any of the Rosewill CAPSTONE, FORTRESS, or LIGHTNING lines are exceptional quality, the same if not better than high end seasonic, corsair, etc, and they cost significantly less money. Also all CAPSTONE and LIGHTNING are rated 80PLUS GOLD and the FORTRESS line is 80PLUS Platinum.

I personally run 6 GPU's (5850 and 5870's) off of a 750W NZXT HALE90 (80plus gold) and it doesnt break a sweat. It was expensive and wasn't aware of the rosewill lines at the time, but it works great and it's also single rail.

This. I have a Rosewill Fortress series 550watt platinum powering a pair of 6950's and an i7-920, and it doesn't even break 80% load. Amazing PSU for the money.
