HELP: ax850 cable sleeving problem

post #1 of 13

Thread Starter 
Hi guys

Major issue! I have been cable sleeving my ax850 modular PSU and I have been following a guide. The sleeving itself went great (doing my 24pin ATX cable) but, I have since noticed I have made a serious mistake.

The guide I have been using shows images with all wires pulled out... I copied and pulled all my wires out... however, unlike most ATX cables my ax850 doesn't use colour coded wires. They are all black CSA TYPE LL47556 TR-64 24AWG FT1 90C -F- wires. Therefore, I don't know what wire is what and where they should go.

Because they are all made from the same gauge wire does it matter which goes where...?

Any advice?

If you pulled out all of the wires and they are all rated at the same gauge, then you should be able to put them in any receptacle.

For reference here is the AX850/AX750 pin out diagram:

AX750-850-24-Pin-Belegung.jpg

-12V and PS_ON are normally rated at a small gauge since not a lot of current is drawn through them.

Quite sure it matters how you lay out the wiring, I know sometimes a cable starts on one pin hole and ends up crossing over to a different pin hole.

The way the AX series is laid out is just retarded. I made custom length cables and when i went to do the 8 pin and 6 pin it was difficult. I had to take out one pin at a time since you would start at one pin, and on the other end you would be at a different pin hole that's not exactly across.

But then again I'm not 100% sure so maybe someone with more electrical knowledge can chime in.

When it comes to the EPS/CPU 8 pin, PCI-E 6 & 8 pin connectors as long as you match 12V to 12V (usually yellow) and Ground to Ground (usually black) it doesn't matter. Be especially careful with the PCI-E 8 pin connector though as that consists of 3 x 12V wires and 5 x Ground wires. A cheap multi-meter is useful for testing them before use. A PSU tester similar to the one below is also useful but as yet the ones I've seen don't have a test for the 8 pin PCI-E connector.

The AX850 (and the AX750-650 etc) don't have colour coded wires... they are all black with no identifying features.

But from what you saying, I should be able to findout the appropriate wire for each slot using a voltmeter...?

The pin out diagram shows you exactly where to wire the 24pin, can you read it ok? If not I can explain it further.

Typically there is a base layout for pcie cables but we need to find someone else with a 750/850 to make sure. That will be your best bet to make sure its right.

Reading the pin out diagram isn't an issue... my problem is that the wires on the AX850 are all black and have no identifying features, therefore it is impossible to know which wire is for the 12v or which wire is for the PS_ON or which wire is for the P.G. As I stated in my OP, they are all made from the same gauge wire so it could be that it doesn't matter which wire goes where... but, if it does I don't want to test it on my motherboard and have the thing blow-up on me.

If you have any further advice Lutr0 it would be much appreciated.

That's what I thought you meant. No, it doesn't matter which wire you use as long as you match the correct pinouts on the connector.

Lutro0 and others plus extension cable manufacturers tend to use the same gauge of wire (18AWG) for all the connections.

Ohhh I misunderstood you bud, Yea like BE said it does not matter. There might be one wire that is smaller guage, but if not then no worries. Let us know if there is any more questions! I hope you get it worked out.
