NON Modular TO Modular PSU

[CyberBarby]

Hi, i was thinking about how to mod a non modular power supply, the Corsair VS 650, to a modular power supply. I have already see a topic about this but all it says is "You better buy a modular psu", "it's not worth it", "you can burn your entire city", and so on. I know that is a pretty hard work to do but I want to do this project only for personal fun, and nobody can't stop me by doing this. So, is there anyone who have done this before? How can I do that? I'm pretty good at electronics so I was thinking about open the psu (already know the risk),  cut the wires and crimping them to the various connector, 24 pin, 8 pin and so on. Can anyone give me an advice about modding a non modular psu to a modular one?

I don't condone opening your PSU!!

 

BUT if you know the risks then i think it'll be just like sleeving your own cables, chase them from the plug back to the PSU and just cut one at a time.  Leave plenty at the PSU end for movement when placing the PSU side connectors and you should be golden.  Have a bum around on ebay/local computer shops for a broken modular PSU and it may be cheaper than buying the plugs/sockets themselves.

This will give you most of the details you need  Have a google for anything I've missed

 

Edit:

Masking tape and a pen will help too, and a letter of funeral instructions just in case

I know the risks of opening a PSU, I know. I simply don't know how to start, i don't know if simply cutting the cables and add molex and 8 pin connectors is the way, or if it's more "clean" to open tbe PSU, cut the metal in the shaoe of tbe connector and create a "real" modular power supply.

It will not be clean since you cannot mount a PCB with modular connectors on it like how most boards will do so. Before modular PSU's the common practice was to splice the end of the cable coming out the PSU short and to use a connector there to then essentially create an extension from there on out.

 

The time and cost associated with doing this especially for such as low quality PSU would be more than the actual cost of any usable unit. Unless your planning to use it for some project with high wattage needs on a 12V rail it's not practical.

The only way to do it and do it right is to take two PSUs:  One non-modular and one modular, cut the wires of the non-modular down and solder them onto the modular interface PCB of the modular PSU.

 

Does that sound worth it to you?  I mean... it might be if you can find a dead modular PSU to scrap the modular interface out of.

 

Alternately, you do as W-L suggested.  That's actually how the "original modular PSU" from Performance-PCs looked.  They cut all the cables down to about 2" length, crimp on connectors and then your "modular cables" are actually store bought, off the shelf extension cables from Silverstone, Bitfenix, CableMod, etc.

Just get a new PSU. That PSU isn't that good anyway...

[orbitalbuzzsaw]

No point .For the amount of time/money you spend to do that you could just get a decent PSU. The VS isn't that good anyway

Yeah, the VS sucks a lot, it makes a lot of strange noises, I've actually changed the fan of the psu to a corsair one. I've made a lot of research on the internet, and you are all right: the time spend and the money are not worth for a diy project. It's more convenient buy a modular PSU unit. Thanks for all the advices!
