PC grow box, wiring issue (picts)

So my issue is i am making a pc box, and i want to use the old fans it had already in it (2003 fans Dell)
I even bought a new power supply that has easy plug-n-go wires. I was told it would work for all my fans.... But the ones that came stock with Dell computer, the plugs are such to small!! It wont directly plug into ANY of the 5-6 plugs my power supply has. I have newer fans comign n the mail, should i wait for them and hope they plug in, or is their any way i can get some help to figuring this all out?
EDIT:
Pict 1) fans came with computer
2) the small ass plug on the stock fans
3) my power supply box i ordered offline

EDIT:
Edit: the back syas "5W190". is my fan 190mm?

Those connectors are designed to be plugged into a motherboard. You need Molex connectors to match your power supply, or you could use a 12v battery charger to run those mobo fans.

dont got ne

k

the large bundle, connect the only green line to a black line in the same bundle. thatll make it start when plugged in. the fans, take the 4 pin lines (would normally plug in to the CD-ROM or Hard Drives) on the PSU and chop em off. do the same with the fans. match black to black and red to red. if u want to make the fans run slower, match red fan to yellow 4 pin connector.

hey thx on info.
ok so just red to red /black?? really? what bout the other wires,r they just useless?? And im sry for this question im gonna ask,
but do i just cut with off the plastic plug, and wire shit together , by twisting it?? Im dumb sry

yea cut em off, n twist em. thats all u need to do. the large bundle is what powers the mobo with different voltages.

the green wire in the large bundle is the power on signal, but grounding it out to a black wire in the same bundle itll auto power on, when the psu is plugged in to the wall. the fans u have normally plug directly in to the mobo fan headers that are powered through the large bundle. because ur not using a mobo, u can directly connect the fans to the 4 pin molexes (cd-rom, hdd power lines). as stated above, the red line provides 12 volts and the yellow 5 volts. the 2 black lines are grounds. just match em up and ur good to go. id say use wire nuts, or at the very least electrical tape. dont cut off all the other wires jsut because ur not using them, it could cause a short. just ball up all the ones ur not using and zip tie em so they dont take up a lot of space.

For the PC Grow Box, Get 80MM fan and hook them up to a 12V DC adapter.
