switching Power Supplies_dangerous?

by maxpain . Updated 24 years, 6 months ago

hi,

I want to switch power supplies to see if one of them causes the problem with my PC, but I’m not sure how relevant the differences of this 2 power supplies are.

PS 1: JNC Computer Corp. Switching Power Supply
Model: LC-235 ATX
(the one that might be defect, worked on a Intel PIII 700MHz/FSB 100 system)

Input: 115V/230V~ , 6/4A , 60/50HZ
Output: 235W

+ 3.3V = 10A
+5V = 19A
+12V = 8A
+5VSB = 1A
– 5V = 0.5A
-12V = 0.5A
PS-ON
P.G

PS2: EC Model: 200X/250X
(the one that’s surely ok, worked on AMD Athlon 650 MHz Abit K7 Pro mobo)

AC Input: 200~240V, AC 3.5A, 50/60HZ
DC output 200W: (there is a mark beside “200W” so I think the label with the specs was made for 2 models, ’cause there are also details on “DC output 250W”)

+ 3.3V = 12A
+5V = 20A
+12V = 6A
– 5V = 0.5A
-12V = 0.5A

the details for “DC output 250W” are:

+ 3.3V = 14A
+5V = 22A
+12V = 9A
– 5V = 0.5A
-12V = 0.5A

I don’t know if the details above are of any use to you, I added them to make sure you know everything about the power supplies that I could find out.

I’d like to know if I can use the PS2 on the comp whre PS1 worked.

thx in advance, perhaps there are some technicians out there who know such stuff.

best regards,
Markus
