Molex connector

[Mohmed97]

What is the maximum  amperage a 12 volt pin from the molex can output ?

i installed a 5m RGB led strip which feeds from the 12v molex pins 

the led strip needs 6Amps at full power (white color) but the white color is kind of yellowish 

and I think the molex outputs less than 6Amps I googled this but I saw variable answers 

the psu is cooler master 600w

Cooler Master 600W is almost as specific as "my computer is black".

 

Cooler Master also made bad PSUs over the years, so you'll need to be more specific.

Yes, molex cables supply 75 watts at 12 volts so with Ohm's law that c9mds out to ~6amps.

I measured the current at full brightness (White color ) with A multimeter it reads 0.86amps I wonder why it reads like that as it should  draw 6Amps (2amps per color)

Which LED strip did you buy; can you share a link?

 

Cooler Master's Elite series of PSUs is not very good...they are like Tier-d units...

That said, it should not have much trouble powering a couple meters of RGB LEDs.

46A on a single +12v rail.

 

Is the white LEDs...just not a "pure white" type?

Some RGB strips need to use a combination of red / green / blue to get a white colour.

Some other RGB strips have a dedicated white LED diode (white / red / green /blue).

What lighting strips?

 

White is the hardest color for an RGB LED to duplicate.  It has to be an actual RGBW LED or it's going to "emulate" white as a light yellow or light blue (depending on the firmware).

It is ZhiHeng RGB 5M 5050 led strip not WRGB

as you said the psu can provide up to 46amps but when I measured it with a multimeter it draws only about 0.91 amps on full brightness RGB (white color) , the first 2 meters of the strip is a white color and the rest 3 meters gets yellowish as it approaches  the end of the strip

That's a strip issue. Not a PSU issue.

 

Even though your PSU is garbage.

As @jonnyGURU mentioned, the problem may be with the LED strip. 

 

Does it get MORE yellow as you go further down the strip? It might be too voltage drop as you down down the entire LED strip length.

 

Current shouldn't be the problem, as the PSU will supply as much as the hardware / component require.
