Is this 6 pin to 8 pin pcie connector usable in a custom pc build?

"IMO" based on what?

Are you asking why I think it would be fine? 1. Sufficient wire gauge, 2. Quality of manufacturing.

also why cant a 400W PSU support 150W on a 12v rail if it's designed capable of so? in fact i believe most unit could deliver their full capacity on the 12v rail alone

I'm referring to a 400W PSU with only a single 6-pin. You're invalidating your own argument if you tell me it's fine to pull 150W from it.

also, you may be right, the 6-pin may be able to handle it, but how can u be certain other than to test the cable out yourselves

Simple, read the print on the side of the individual wires. 18AWG x6 wires on an 8-pin cable with 2x jumping off 2 grounds (150W), 18AWG on x6 wires on a 6-pin cable (magically can only supply 1/2 the power). Do explain that. The 6-pin/8-pin standard is pointless if you know what you're doing (which to be honest most people don't so that's where the "buffer" comes in you were discussing - it makes sense why it was made but physically it's not valid).

granted, a lot of PSU actually pulls the extra 2 pin from 2 of the 6-pin. if u adapt those 6 pin to 8 pin then it's fine since you're just splitting the connection further down the line.

Thank you. That's all I was looking to get across.

(but then why would u use the converter anyways lol)

 

I gave one example but agreed 95%+ of the time the situation wouldn't come to pass.

anyways we derailed the topic too far imo, it's basically "common sense" vs "by the book" if u ask me

 

@NoobBoimaybe you could find out if the PSU is using proprietary mount and cables, if it is then it's very tough to swap a new unit in, but if it isnt maybe you could get another server PSU that fits your needs, would be my recommendation

Would this work (be a bit safer)

Agreed.

I will use a dual 6 pin to 8 pin, thanks for the help.

Well, you don't have to worry about overloading any wires going that route. I do think it's a waste of a 6-pin though if you ever need a 6 & 8-pin or dual 8-pin down the road.

 

You never did mention what PSU you have. What are we working with where it doesn't have an 8-pin but dual 6-pin? Usually a pretty low wattage unit.

 

Regardless I'm glad you found a solution that will work for you.
