what about using a 5V from 1 psu and a 12V from another psu. they are different brands of psu's but same about (250 watts) i havent tried doing this yet, but if this would make like 17V at 35A that would be overkill. please tell me if my math is wrong her and explain what's right. if this doesnt seems to dangerous to do, ill try putting a meter on it and see what the reality V and A is. thanks again

Dix Dogfight is right: the amp rating you'll be able to use is the smallest of either the 5V line or the 12V line. Just look at the rating on the power supply. Also, try not to use a full load: if you need 35 amps, then shoot for a supply setup that will give a little more than that, like 15-20% more: it'll keep the PSU from heating up, and wearing out prematurely.
Make sure you use MBM to monitor your CPU temp, and allow it to shut off your computer if the temp gets too high. You would do well to do this, since your PSU setup may not be 100% guaranteed reliable.
