Modular cableing?

[HannibalX]

I have read on certain websites that modular cableing can reduce the performance (for lack of a better term) of a PSU? Is there any truth in this?

I am looking to move to a modular PSU to clean up my case a little. The PSU I am looking at is the ENERMAX Liberty ELT500AWT ATX12V 500W PSU which will replace my Antec TP 2.0 550W PSU.

Does anyone see a problem with this swap for my system? System specs in sig.

Seems the modular plugs cause an itsy bitsy increase in resistance, but nothing to get excited about. My system is similiar to yours, and runs just fine on a Seasonic M12-500.

There is, as Old Hippie says, a tiny(note: TINY) increase in the resistance of each cable. However, this amounts to nothing of any significance.

Quite a few of them still don't use 100% latching connectors at the PSU so the resistance can get really high all of a sudden...

Funny how many graphics cards, hard drives, floppy drives, optical drives and even some motherboards don't have fully locking connectors and no has cared...

Ever hear of "best practices"? I'm not a real fan of many other connectors used in PCs either.

It's not just PCs...I am sure I am not the only one who has accidentally kicked a plug out of a surge protector accidentally when its at my feet...or turned my computer a bit only to have the power cable come out.

To hold the lack of locking connectors against modular designs(many do have locking connectors however) is unfair IMO.

Both of your AC power cord examples can be fairly easily resolved for critical equipment. Much harder to do on a PSU that lacks latching connectors. I'm just saying that if you really want a modular PSU, give extra points to units with 100% latching connectors.

that would be silverstone. all cables are pluggable, and all connectors are identical to the output end of the cable. it adds about 1 1/2" to the length of the box. i swapped out the stock adda fan for the noctua 1200, and custom harnesses are work-in-progress.

If the silverstone has standard molex on the PSU end then they aren't latching and it doesn't get those extra points

That use to be true .....and still is if you get your hands on one of the early modular units..
In the last 2 or 3 years it has become a non issue.....although some companies use it to promote there non modular PSU`s.

Now a days the difference if any is hardly even measurable!!

yet the type of connector used does actually make a difference!!


Peace!!

"3. DON'T LOSE POWER WITH MODULAR PLUGS
Due to their look, convenience, and cost savings for manufacturers, modular plugs have become a popular power supply feature. Unfortunately, there has been little or no discussion of the impact of this feature on overall performance and reliability. The fact is, modular plugs limit power by adding to electrical resistance. The voltage drop can be as much as would occur in 2 feet of standard wire. Worse yet, modular plugs utilize delicate pins that can easily loosen, corrode, and burn, creating the potential for a major system failure. That's why professional system builders specify uninterrupted wire!" http://www.pcpower.com/technology/myths/

Again thats a myth that was true at one time...it is noe a Myth and just more PC Power & Cooling FUD!!!
