how to jump a psu

Busty St. Clair · Mar 13, 2004

well i think i'm going with the danger den pump unfortunatatly i have to wait a few months to purchase oh well the pump runs of the psu and when i bleed the system i'll need power so how do u jump a psu

connect the green wire to any black wire, you can use a paperclip if you want, but make sure you have something else on there drawing power on all the rails besides the pump. ex, fans hdds lights..

pins 4 and 6 if the clip is on the top a paper clip or solder (which i use)

y can't i only run the pump off it

TheGhengisKhan · Mar 13, 2004

the power supply requires some kind of load on it to function properly, or you could seriously damage the PSU.

so apparently my old psu is weird it only has the 20pin mobo connector with no green wire but i think it's the blue one since on my new psu it has a green wire in place of the blue wire

You can't fill and bleed with your computer on at the same time? Bummer...maybe I should rethink buying the Swiftech MCP600

that bypass you linked to just does what has been said about a paper clip shorting the green and black wires. it wouldn't be worth it IMHO

Shadowcat · Mar 14, 2004

I agree with zip22, I should think only idiots with too much money, or a total lack of knowledge would buy that...

Xenocide · Mar 14, 2004

you can fill and bleed with your computer on if you have a hsf combo on your computer and your wc equipment still hooked up, just without your blocks mounted...

Busty St. Clair · Mar 14, 2004

but why should u also have other fans and whatnot connected, why can't i just have the pump connected

NavyDood · Mar 15, 2004

Leave everything as is in your system. Pull the motherboard power connector and use this picture. Your case fans and everything will come on.

Busty St. Clair · Mar 15, 2004

but i still haven't gotten an answer y is it that people say to run other stuff a jumped psu like case fans and not just one thing

I believe as long as something is connected (ie your pump) you'll be fine. Just make sure the pump is always on while you have the psu running.

It is possible to buy 13.5vdc or 13.8vdc ("car battery voltage") plug-pack power-supplies rated at about 2A (what I'd recommend as a minimum amperage rating) for around $15US or so.

What this buys you is the ability to run the pump without jumping the ATX PSU, and you get to run the pump at slightly above 12v, buying you yet more performance.

The Swiftech MCP600 when run at 13.5v will match or exceed the Iwaki MD15-R or Danner Mag 3's performance for the sorts of restrictions offered by most people's setups. It's also substantially easier to feed in a thin DC power line into the computer, rather than a thick AC line.

People reccomend having more load on the power rails because otherwise damage may be caused to the PSU without proper loading.

This has already been stated. What we want to know is why.
