Dual PSU Question

[fmsam]

So here is the question, up to now I have been switching the secondary psu using a relay, the one I have been using is a standard 4 pin relay as used in the motor industry nothing special,

The pull coil on this item has a resistance of 80 ohms and when energized it uses 160 milliamps, this was driven by a molex connection to the primary psu (relay terminal 85 and 86) to switch pin 4 (green wire) to ground pin 6 (black wire) on the secondary psu (relay pins 87 and 30) to switch it.

I am currently using a Corsair AX 1200 pro, this being single rail, I am somewhat anxious about using the relay, so at this time I am switching the secondary PSU manually each time I start up.

Is it possible that a constant 160 milliamp load on one of the periferal rails is harmfull, and is it ok to hook a single and dual rail psu together.

any input greatly appreciated

Cheers all

Rick

if I recall correctly the pull of 160miliamps is just to switch it not the constant draw which thb should be a lot less. So I don't believe there is anything wrong with that setup. But if your concerned about it I am sure you could mod some kind of secondary start switch to it without a lot of expense or effort. Hell worst case scenario paperclip it and use the rear switch to turn it on and off

I was running the relay with through a Multi Meter, thats where I got the 160 MA from !

Hmmmmm maybe 160 constant is a bit high, TBH Ive kind of got used to using 2 switches, maybe Ill just carry on doing that 4 now.

Chers 4 the reply anyway

i saw a diagram of someone who wired the green and black wires together on two PSU's 20+4pin so they both switched on at the same time
