Most of my risers I just paid a few bucks each for on ebay. I did however buy a $25 riser with molex from cablesaurus. It works great, and the shipping was fast, but $25 is still a complete ripoff.
Supply and demand?
supply and demand would only justify his pricing IF there were a LIMITED supply, which is clearly not the case.
actually supply and demand is a factor...
demand is low... primarily it is only used by miners.
supply is also low... each molex connector is soldered on by hand which raises cost.
then it boils down to how much do want to gain in profit, how much time does it take to add a molex connector.
i add my molex connectors differently so it takes me at least 1/2 hour just to do 1 cable.
if i were to sell them i would be charging a lot more since i think my time is worth a lot.
but i don't sell them... I think I'm rambling now.
I figured that it was well known that demand was also very limited hence not worth mentioning, I should have made it more clear. There is also VERY little demand and a very little limit to his supply.
Also, 1/2 hr?? geez care to post a pic of what you're doing that merits a half hour?? Each once runs me ~6 minutes.
Unfortunately the ones i have are in machines.
have to make some this weekend however... but this is what i do
i carefully cut the ribbon down where the 12V lines are on both sides (A2 & A3, B1, B2 & B3)
then i cut them away from the base of the card edge... and strip the wire ends.
solder a 16 gauge wire to it and connect the other end to a molex connector.
this completely isolates the 12V away from the motherboard and no power is pulled from the motherboard.
hard part is leaving the A1 wire (PRSNT1#) intact and not get it damaged or cut.
i have cut it once by accident and had to fix the wire.
i carefully cut the ribbon down where the 12V lines are on both sides (A2 & A3, B1, B2 & B3)
Thats the same way I made a few of my previous ones but I really hated that free floating A1
So here is my solution
http://tinyurl.com/4xu7tnqhttp://tinyurl.com/3k72u3mbut not cutting any of the wires the riser is no longer required to use additional molexs ( 12V+'s ) except when its required.
The current draw will always take the path of least resistance -
http://tinyurl.com/aynwg http://tinyurl.com/aynwg"Where does the current flow? Current will always try to seek out the source, be it normal current or fault current. As for taking the path of least resistance, that is partially correct. Electrical current will take any and all paths available to try to return to its source. If several paths are available for current to flow, it will divide and the resistance of each path will determine how much current will flow on each particular path."
The molex plug is rigidly attached resulting in less flexing of the ribbons ( more importantly the solder joints which have no strain reliefs )
No more of this Zip Tie BS
