+3.3v = 20A
+5v = 35A
+12v = 17A


maybe is the 3.3v a bit low. What problems could cause that?

with K7N2-Delta-ILSR and 2600boxed

i just replaced my allied/deer 350
for a 400 fortron pfn

i will post my new voltages asap

looked last night
the allied was always over the number ie 5or 12

some of the fortrons numbers are under ie 4.8

what is the ideal range numberwise for example +12 within 11.50-12.50

i also noticed the numbers on fortron werent fluctuating nearly as much

3.3 and 5 v should stay within plus or minus 5 percent,a good psu will manage 3 percent

12 v is allowed 10 percent ,again a good one will stay within 5 percent

This is what I got on the sticker:

Switching power Supply
Model: LC-B350ATX

+3.3v - 28A
+5v - 35A
+12v - 16A

+5VSB
-5v - 0.3A
-12v - 0.8A


My PC just shuts down about an hour after switching on.
Sometimes its even less.

I thought it was an overheating thing but someone said it may be a PSU problem.

I read that article on powersupplies and it got me thinking.

I hope you can help.

hard to say as what you have amp for amp is the exact numbers ive allways said each rail as a minimum should be

well you dont give temps and i cannot read minds

it may be it cannot actually poke out what they say

it might be irq related has vga its own irq

bad memmory

Memtest86

lots of things

if you had said 3.3 v 14a i would say chuck the psu

but as it is it just meets the minimum specs we have been saying

note the word just though

hello, there

I retired read all review on websites about power supply and support forum, I did little understood about watts, volts, amps.
And I found website on [ http://www.jscustompcs.com/power_supply ] for power supply wattages calculator, but I don't understand that, why I choose PSU high?

I don't know choose Antec truepower 430 , 480 , 550 Watts? How much PSU on my system? If I choose 550 or 430 Watts, so is this problem or not?

My system had:
MSI 865PE Neo2-LS
P4 3.0GHz + HT + 800MHz FSB
2 x 256MB DDR400 PC3200
MSI Geforce FX 5600-VTDR 128MB
WD 80GB and 120 GB IDE HDD
LG 16x DVD-ROM
Lite-on 52x32X52 CD-RW
US Robotic 56K v.92 PCI
4x 80mm fans and Cold Cathode Tube Light
Antec PLUSView1000AMG Case (no power supply)
Sound Blaster card

Please help with send me for problem solve..thanks

My antec True380 PSU says:

+5V 35A
-5V 0.5A
+12V 18A
-12V 1.0A
+3.3V 28.0A
+5V SB 2.0A

So how do I calculate the real power of my PSU.

Should I do:

5*35 + 5*0.5+ 12*18 +12*0.1 + 3.3*28 + 5 * 2 = 496.02 W

Is it correct?

Wonkanoby, you said "sort of but the psu has an overall max amps for the 3 rails it will never go over and thats a lot less".

What does it mean by an overall max amps for the 3 rails? When you say "rails", what are you referring to?

Also, so what is the really power of my PSI then? :confused2:

(Sorry for my ignorance to raise these questions?)

the limit is as in the above in red highlight



+5V, +3.3V & +12V maximum output 360 Watts max

this is controlled by the gizmos in side the box

to that gets added the other 20 watts of power that the sundry minor voltages give

so as they say its a 380 watts psu

each rail if you look on its label can give a max amp

in the case of the antec one gives juice at 3.3v one at 5v and one at 12v

most normal psu have two basic rails 5v and 12v

the 3.3v is then made from its 5 v out put

so they are tied together

the more 5v you take the less 3.3v you can have

there are loads of threads here on this

why i choose different between of power supply watts? I checked the label for the exact combined power 3.3V+5V and range amps, but which one best range amps of antec truepower? :noidea:

I don't want to damage or crash or fire up my motherboard, and etc. :shocking:

Please help with send me for problem solve..thanks :-))
