Would 4x equal power supply connected parallel give out 4 times current?

Hi Is posible from one pc power supply get out max current 80A (12V) if you connect together V1, V2, V3 & V4 wires into one (this will be +) and ground (black wire for -). This is not for PC I just need higher current power supply. Here is specification for power supply: Specification Input: AC input... show more Hi
Is posible from one pc power supply get out max current 80A (12V) if you connect together V1, V2, V3 & V4 wires into one (this will be +) and ground (black wire for -). This is not for PC I just need higher current power supply.
Here is specification for power supply:

Specification

Input:
AC input Voltage: 95-132VAC or 190-264 VAC switchable
AC input Current: 8A res max. for 115VAC 60Hz, 5A res max. for 230VAC 50Hz
Overload protection :150%
Output:
+12V1 20A
+12V2 20A
+12V3 20A
+12V4 20A
+5V 30A
+3.3V 30A
-12V 1.0A
+5V/SB 3.0A
