What surprised me the most is that one of the AT PSUs is really, really heavy. It's a 400W monster! I've never seen such a powerful AT PSU! 😳

40 amps on the 5v Rail?! Goddamn, that's one heck of a 5v supply, I think the only other thing I've ever seen that had that much power on a 5v rail was a 1500w Silverstone power supply from a few years ago. http://www.newegg.com/Product/Product.aspx?It … N82E16817256054
There were also these monsters: http://www.legitreviews.com/ttgi-tt-600k04-60 … -atxbtx-psu_164
These are "FireFlower" brand power supplies, which is a division of FSP Group, the high end OEM server power supply company that produces high-wattage power supplies for dell and HP servers designed for 100% load 24-7 operation @ 100% duty cycle. The TTGI brand was their consumer division selling exotic consumer power supplies. However this later "600 watt" model, was the beginning of the "modular +12v" era, when modular consumer power supplies with decent +12v started appearing, but some systems still needed heavy +5v as well.
The "last of the great non-modular units" was perhaps the SuperFlower/TTGI TT-550SS with a whole 50 amps on the +5v rail. Not modular at all, and was this one: http://www.overclockers.com/super-flowerttgi- … s-power-supply/
They're pretty rare and hard to find (either one) today, but I do have a TTGI TT-450SS in my AthlonXP (Even though it has a P4 plug on the motherboard) machine that has 43 amps on +5v and I'm using it for that machine It's my one I posted on here, that gigabyte board with the 3200+ Barton-400 chip in it, and this TTGI 450 watt one has it stable at 2500 mhz something.
Occasionally these TTGI units pop up on ebay, usually in the 400-450 watt range, I managed to score mine for $20 flat after shipping. People are selling these low because of the low +12v side, so they're not usable for "modern" systems.
Also some of you may be more familiar with SuperFlower's modern-day name when they run the FirePower brand of power supplies. The company bought out PC Power & Cooling a couple years ago, and changed the entire PCP&C line: it was re-branded to FirePower.
EDIT: My TTGI is using thick 16-AWG wires for both the ATX plug, and for all of the molex and sata plugs, stranded-copper in the wires and actually uses copper connectors inside the molex plugs and atx plug too. They're pretty nice units if you can find one and get your paws on it.
