The amp ratings specify the maximum possible current draws, not what
the power supply will always put out because the computer determines
that, limited by the capacities of the power supply. The new supply
should meet your needs despite its lower +5V and -5V amp ratings
because:

1) Any computer built in the past 5 years loads the negative voltage
outputs only negligibly, if at all;

2) The 12A rating for the +12V is low for a 350W supply, indicating the
supply is of low quality;

3) If your motherboard uses a square 4-pin connector in addition to the
20-pin connector, it draws few amps from the +5V output and more from
the +12V.

The best manufacturers include Fortron-Source Power, which puts out
many brands, including Sparkle, Hi-Q, and anything whose model number
starts with "FSP" (no all FSP model numbers do), Zippy-Emacs, Astec,
Newton, Lite-On, Delta, PC Power & Cooling, and Antec (actually not a
manufacturer, but they market the better products from Channel Well
Tech.). Fortron-Source should be strongly considered due to their
combination of highest quality and unusually low prices.
