multi-rail gpus scare me because I never know if I'm load balancing correctly; i'd rather just spend the extra $30 to get a single rail psu that does 100 amps on 12v

i agree..

Just lookin to speed up the process of getting rolling..

can anyone provide me with any information on how to tell which cables are run off which rails and what not?

You could contact the manufacturer but other than that I think trial and error is the only way to find out.

the manufacturer was actually smart.

the main bundle of cables is run off rail 1, there is a bus of of cables for the modular cables that runs off rail 2, rail 3 and 4 have separate dedicated 6pin connectors...

This is really a great setup..

Found a pic for you, it looks like that power supply gives even less +12V than that:

The fact that the rating plate has stickers on it.....

Enough said.

pardon my ignorance, but what does the fact the plate has stickers on it have to do with anything?

still new to this bitcoin thing.. my previous setups really didnt matter, so how do i tell which cables/ports go to which rail?

A 5970 uses 300w, a 5870 about 175w. Total, that's 950 watts of +12V power, about 79A.

The TPQ-1200 is more in line with these power requirements, here's a review.

Note the load tests on that site, where they test it with +12V 90A, (and 10A on 3.3V and 5V) = 1200W, also +12V 98A (and 1A 3.3V and 5V) = 1200W. It doesn't go up in smoke, many other crap (ahem..Thermaltake) power supplies die when that site tests if they can deliver rated power.

cool... well i happen to have one of these 1000w ps sittin around doing nothing, was thinking of not spending the cash on a seasonic until i got my 3rd 5970... that may not be a good idea

For what happens when you run a power supply near max, look at the noise graphs of the TPQ-850 here, the more you push a supply near max output, the more line noise and ripple you get, more likely to make your system crashy.

Just thinking about using this to power 2 5970, and 2 5870's? will this do it? or is it a bit shy on bein able to manage that?
