How much power per 4-pin connector?

I have a 400w power supply with 4, 4-pin connectors. How many watts does each one of these have? My two 120mm Sunon's that I just put in consume 6.8w each and I am wondering if they should be run together, or if I should run one 120mm with the CPU fan, and the other 120mm with my hard drive fan. Thanks
 
hey metalloid15,

it shouldn't really matter how u connect up ur fans. i personally like to just hook up the fans together, and use different ones for my other stuff, tho this is just a preference of mine. i'm currently running 4 panaflo L1A's on my case, two of which i hook up to mb headers. only warning is don't hook up high power fans to the mb fan headers, as this may cause problems.

They all have the same cumulative power. The actual cables are able to handle enough load all by themselves, so it doens't matter how much you have on each 'connector', but rather how much you have on the power supply total.
 
So what you mean Scootin159 is that I could run 2 fans on one header, and nothing on another, and it would just give the empty header's power to the header with 2 fans? I guess that makes sense. Thanks
 
Yep, you can chain up as many devices (within reason) on the same 4-pin connector as you want. What kind of PS do you have that is 400W yet only has 4 4-pin connectors? That's kinda chinsey!
 
Ok I went and measured the actual power output of the connector. It turns out that it pumps out 1.21 Jiggawats of power! I wonder just what kind of capacitors run it at that speed!?
 
LOL, it was a joke. 1.21 Jiggawats is what it took to run the flux capacitor in the movie "Back to the Future" to enable time travel. The real output of your PS is usually a range. For 400W power supplies I think it runs 200-400W (400 is the max). 400W is plenty for pretty much anything though. Rest assured you can have 10+ 4pin connectors with no problems whatsoever (I do this with a 300W PS).
 
If you open up your PS, you'll notice that all the 4-pin molex wires come from the same source 😉 So, it doesn't matter how you use them, as long as the PS itself is capable of supplying the power you need.
