Angled 8pin ATX EPS adapter?

[RejZoR]

I need some extra space at the 8pin ATX EPS connector on top of the motherboard because it's eating into top fan space if I want to use 140mm and I'd need an angled piece adapter. Where could I buy one that is of good quality and really compact. Was searching on eBay and found some, but they are some weird PCIe 6pin to 8pin EPS. There are bunch of 24pin ones, but I can't find 8pin ones.

This is a 24pin ATX...

But I need similarly shaped smaller one for 8pin ATX EPS. Preferably nicer made and more compact because this one is so huge I'd not really have any benefit over a bent cable, price almost doesn't matter

@DeathtoGnomes
Yah, but for ATX EPS power (that 8pin connector next to CPU socket), not for PCIe power.

@newtekie1
Yeah, that would be it. I just wonder if the gain would be enough. Need to check and approximate within my case, this one goes at quite sharp angle close to the part that goes into mobo. I think it should be enough...

 

[Bill_Bright]

this one goes at quite sharp angle

Not sure what angle you are expecting. Unless you go for a cable solution as suggested by DeathtoGnomes, I don't see you finding anything but a 90° angle adapter.

But frankly, I'm not sure using a cable type adapter would offer any benefit over the actual power supply cable. You don't want to bend the cable so sharply it causes a kink in the cable, but you can still bend it over into a pretty sharp "curve" and secure it with a small tie wrap.

Just remember, newtekie1's 90° adapter can only go in one way too. That means it will hang over some motherboard real estate. And the inserted cable connector will hang over even more. Make sure you have clearance and that there are no tall components mounted on the board that will be in the way.

 

[RejZoR]

Main problem is, factory one with PSU goes from rectangular 8pin connector to a round batch of cables and that is very hard to bend, where this adapter has wires in parallel which go at much harder 90° angle.

From the looks of it, his adapter goes upwards, which is desired. I got some space left at the top, but to the side, it's a fan and that is a problem.

 

[Mr.Scott]

You don't want to bend the cable so sharply it causes a kink in the cable,

Why?
It will not restrict anything......as long as you don't break the wire.

LOL You caught me off-guard for a second. I always visualize motherboards as they lay flat, "horizontally" on my bench so I am looking "down" on the board. So a right angle adapter would put the new connector's end off to one of the four sides - not "up" off the board. You seem to have the board oriented differently in your head, perhaps mounted "vertically" in a tower case, or are calling the back (I/O and expansion slot side) of the board "up" - like some people call north "up".

Anyway, it seems like newtekie1's find would be your best bet!

An actual kink does indeed cause restriction (or more accurately "resistance") to the free flow of electrons in the conductor. Bending (putting kinks or creases) in the metal wires causes microscopic (visible in larger wires) stress fractures in the metals. That can eventually result in breaking the wire. Kinks (full bends vs curves) distorts the shape of the wire which can damage the insulation - this could be a greater issue (including shorts) with the internal individual and adjacent wires. And as noted, kinks also increases resistance through that part of the conductor (wire). That increased resistance results in increased friction as the electrons bang about navigating corners that should not be there. Friction causes heat - never good.

While such problems at these low voltages are not likely to cause hazardous overheating conditions, it is just plain, simple, bad practice to allow any electrical wire to become misshaped or kinked. Proper cable management means curves, not bends. If you need a bend, do as RejZor is wisely doing - use an adapter designed just for such purpose.

BTW, ensuring there are no kinks in data cables and RF transmission cables (and waveguides) is even more important as such added resistance will actually change the characteristics of the conductor and that can cause synchronization problems, or significantly attenuate the signal. This is why the "bends" (really curves) in RF waveguides are "tuned" to the specific frequency of the RF being transmitted through them. This is why when pulling CAT-5e or CAT-6 through walls you need to be particularly careful not kink or crease the cable, but instead, gently curve around corners or you risk changing the impedance and/or electrical characteristics of the cable. See Bend radius for more information.

I disagree. As long as the wire is not physically damaged.

And I'm not talking about cat cable either, as it was never mentioned in the OP.

 

[Bill_Bright]

Funny how you ignore the "and no" part of your own reference. Did you even read the very first reply?

I feel you joined this thread, as you often do, just to argue. If you want to do that, I suggest you sit in on any 7th grade beginners electronics class and learn what every student of electronics learns and what you clearly don't understand about about wire conductors. But before you come back with some contrary comment, at least do this; picture in your mind the difference between a round wire and a wire that has been bent/kinked and how that might affect the "skin affect" of that conductor.

I'm out of here.

Actually cables have something called a bend radius, which is how much you can bend it expressed as X times the cable diameter, imagined as going around a pipe. Or rather, it's a guideline provided by some engineering organization.

Some cables have such tolerances in their spec sheets. PSU cables can be pretty stiff, so you definitely want tobe careful not bending them too sharply.

I don't really care what you think. I responded to your comment with a direct link to an electronics engineer's Q&A that contradicts what you said.
That's all.

But that link is a non-answer in this context. How does he define a bend? A proper bend (as a curve) or an improper one (a sharp angle)? Because sharp angles definitely has an effect, this is common and correct knowledge. Take a 10GbE cable and bend it 90 degrees and see how much performance you lost. It will be noticable.

As stated before. I'm not talking about cat cable, sata cable or the like.

Power cable isn't like a water hose, where if you kink it it shuts off. Kink wire all you want. As long as what's inside the insulation isn't broken, it still conducts power.

Yep, this is why we use ductile metals like copper in electrical wires. You can bend an 18AWG copper wire back on itself and not cause an issue.

 

[John Naylor]

This is a power cable and power cables are bent and all the time.... no, most of the time. Not in big plants that I typically find myself in daily, but house wiring and smaller. Doesn't start to be a concern until wires get way bigger than you'll find in a PC. A 90 bend is very common going into any switch or outlet box. And 180 bends are the rule at any attachments. And this is usually SOLID wire. When you get up into large wire sizes, bend radius is a "thing", but there's none those "things" inside a PC case". As you can see plainly here, no bend radii are specified for 10 - 14 AWG

[MrGenius]

Also, electrical resistance has absolutely nothing to do with friction. Which electrons do not experience. And, therefore, is not the cause of resistive heating(a.k.a. Joule heating).

And the "skin effect" has nothing to do with DC.

It does, but it's still not recommended to do sharp bends like that. And bending by definition is physical deformation, very close to "broken".

Also, this.
