Are extension cables bad or good?

[ZidaneTribal]

Hi,

I'm planning to use extension cable for my 8pin cpu, 24pin, and 8pin vga for aesthetic purpose. Are they bad? reduce performance? or can damage our power supply?

My current power supply is corsair RMX 550w.

TIA

They do not do anything bad.

It's literally just a cable.

They introduce a little bit of resistance, depending on how long your cable is, it might affect the performance.

For reference, shielded 22 AWG twisted pair cables have capacitance in the range of 100-240 pF/m. So the maximum bus length of an I2C link is about 1 meter at 100 Kbaud, or 10 meters at 10 Kbaud. Unshielded cable typically has much less capacitance, but should only be used within an otherwise shielded enclosure.

Edit: for your application, don't worry about it.

it's a cable, the longer run technically speaking introduces more resistance which results in more voltage drop, so in theory you might not overclock as far as you could before, but you would need like bleeding edge, couple of Megahertz faster and you aren't stable level OC to ever notice, provided they are quality cables and not complete trash and of a thinner gauge or uses Aluminum in place of Copper strands or some other shit like that, in otherwords don't just buy the cheapest shit set you can find, get the nice CableMod Pro ones.

He told me that he used good quality product. Here is one of the examples

It looks fine, rule of thumb, the thicker the wire, the better.

fiuh.. Im relieved then.

Glad my extension cables are good.

Nice, lookin good.

Yeah, a few micro ohms, which will literally not make any significant change to the voltage.

Also even if it did change the voltage slightly it would not matter because all components like the motherboard and GPU have their own power regulation circuitry.

If the voltage is 0.01v too low it will simply draw a bit more current.
