PSU Doesn't Have Required Cable.

[DarkendDay]

When putting together my computer i found that i did not have a cable that would fit in the psu connecting my seasonic evo edition 620 watt to my cpu1, which the motherboard is a mag z390 tomahawk.  Although I do have a cable from a evga 750 watt psu that does work with both the motherboard and seasonic power supply.  If i used the evga cable would i run a risk of damaging any of my parts from using a cable from a different psu?

Nah, don't mix and match cables. Also, I'm pretty sure you only need the 8pin for the CPU to work.

As said a single 8 pin CPU connector will be enough even with overclocking, it's only if you are going to extreme levels that it really requires all the connectors. Don't mix the cables between different manufacture's they have different pinouts.

If the cable fits into the power supply there's nothing wrong with using it.

Pinouts on fully modular cables can be different on the PSU side, mixing it may lead to the incorrect voltages going to the pins on the component end.

That's a great way to connect 12V to where it should be ground. 

Please don't give advice that will destroy others' PCs.

You have no idea what you're talking about.

I take it you haven't seen the PSU side pinouts for different brands (and even different PSUs within the same brand), and you haven't played any attention to anything regarding PSUs?

That's just wrong, if the pinout is different the connector would be different. They don't take a wiring standard and go "well screw this let's just mess around with which pins go where for absolutely no reason whatsoever". If it fits it would work.

That is the case on the component side on the PSU ie the 24 pin, PCI-E, and EPS. Each manufacture's has their own proprietary system and pinout for wiring their modular cables that is non-standard, so mixing a cable can lead to the connections being crossed on the component side and frying something.

For real? Are you serious?

 

As stated, even different line-up's from the same manufacturer can use different pin-outs on the CPU or even switching pin-outs on the MB end of the connector. Please don't recommend (false) advises that can ruin other peoples computers costing them hundreds of dollars worth of damage

Your PSU should have a 4+4 (8pin) CPU connector. Plug that in to the 8pin socket on your motherboard. Leave the 4pin power socket next to it empty; it's not required.
As others have mentioned; do not mix cables from different power supplies.

Why not run the EVGA PSU in that system? It would most likely be a better unit than the Seasonic M12ii 620W.

Hey, everyone. Don't trust this advice. There can be plenty wrong with using a cable not intended for your power supply (as at least a few people have found out to their cost).

Pretty sure the Science Studio guy on YouTube destroyed some equipment doing exactly this and then had to film an apology video after blasting the manufacturer for their "shoddy" equipment.

seasonic evo edition 620 watt

Condolences...

Why do people recommend this ancient thing??

 

More Infos:

 

Since it doesn't have a cable you need, maybe replace it with one that does have the cables you want?
One that's actually a decent qualty one...

Upgrading the motherboard and CPU and not the PSU?

 

Noob move.

 

Now's a good time to update the PSU too.
