hi folks

i waz readin' another post while bak. bout the 12v runnin' on high amps able to run a 172w pelt or better or somethin'.

my psu (powermax) is 500w psu. the 12v rail it says 25A iz dat good?

[Brinky]

Power (W) = Volage X Amperage

So... 172W pelt... 12X25=300W

300-172= 128W left for the mother board and stuff... so it SHOULD be enougth... what are your system specks?

I wouldn't trust it. Taking into account the CPU, you only have around 50 watts left. One DVD-ROM and one CD-RW leaves you with 14 watts left. One CC makes 6 watts.

I would seriously make the investment in a dedicated PSU.

yeah well the cpu dont use the 5V rail that much...

i know that HDS use 12V to start then when runing ONLY use 5V
u can always go to radio shack buy a amp meter that clamps and measure the cosume of the 12V rail.. and then u have FACTS...

but up to you... if your got the moeny go buy a psu..

ahh thats the thing. i already have a meanwells psu for my 226w pelt.

and system specs r as follow

amd athlon XP 2000+ usually OCed to 1.85ghz (148mhz fsb @ 1.85v)

2 sticks of samsung DDR400 256megs

1 dvd-r/w/+r/w/cd-r/w drive (sony dru500a)

1 cd-rw 40x

1 dvd-rom drive

hercules 8500LE 128megs ddr vid card

(1 60mm fan runnin' off motherboard)

3 80mm fans run on molex.

2 120mm fans run on meanswells psu

well yeah there is lots there that pull 12V rail... to get a rougth... get all those devices look on the label... and calculate... all of them say how much it takes of 12V and ddr takes 3.3V and cpu a bit of each.. its worth trying if it over load the PSU will just shut down

no worryes
