Anyone have a TX850W

[Uranium-235]

I had one of these that had a shutting down issue, turns out the motherbord PCI-E main was overloading causing shutdowns. I took it back, got the new one and after some time, the two video cards would burn the atx pins over time, causing corrosion and eventually the same problem (corrosion causes vdrop and increase pull)

I replaced the connectors with clean ones, but I think I soldered the wrong wires. As they are three of the same color, but two of a different thickness. When I put it back in, turned it on, it fried the video card, which of course is on the PCI-e wires I soldered. I looked on google images and it didn't help. Does anyone have a TX850W. I has to be that model. the 950 and 750 are wired differently at the atx connector

and yes, on this PSU, two wires go to a single connector, but I think I made a mistake of which ones

Just take a meter and measure what is what?

Re: Anyone have a TX850W

they follow their own wire coloring system on this one

Re: Anyone have a TX850W

It happened once with me . The difference in thickness of a same color is critical . They are from different voltages .

Re: Anyone have a TX850W

Attached pictures of my TX650W PSU.
It matches the ATX spec color scheme exactly.
From your picture yours also does?

Your meter will not care about colors.
Just power the PSU on by shorting the green wire to ground.
Then check that all cables are in the proper spots.
Normally:
Black=Ground
Orange=3.3v
Red=5v
Purple=5VSB
Yellow=12v
Blue=-12v

Re: Anyone have a TX850W

there are three yellow wires on the 850, two connect together. Sorry, doesn't help

The thin one is for voltage feedback (sense wire).
Does not matter where it goes, it just measures the voltage drop in the cable.

Some new pictures attached.

Small one source is eBay but auction ended and picture gone.

Do these help?

Re: Anyone have a TX850W

Pdavid thank you! The two yellow wires with the green stripe are exactly the same. Guage and everything. I finally got around to switching them. I think the yellow is the sense wire and those yellow/green wires are voltage.

I hooked it to a board with no video card. Of course even when my gtx285 burned, the motherboard was spared. No smoke on this try. Put a cheap radeon x600 in there (with only one DMS-59 and I have no adapter). It's a sacrificial card. But no smoke and the lights on the keyboard blinked once (successful post) . So I put a cheap 8600 and verified it booted.

May my original $699 gtx 285 sc rip (bought in '08)

Re: Anyone have a TX850W

I just got a TX850M (the modular cable version) for my socket 1366 rig.
Took a while to do custom wiring to hook up the Alienware Area 51 case.

With the build quality looking good, definitely better than a CX, I got a TX, in case the Antec High Current Pro 1200W PSU takes a shit...

(sagging voltage with the Antec High Current Pro 1200W PSU, even in a review, IIRC!)
