Powering the pump while bleeding.

[BloodWithIce]

I have this cable and an old power supply, I think I should be able to power my 3 pin male pump with it. Is that right?

I believe so

no, the wire on that adapter is way under gauged and the connection is too weak

to carry enough current to power the water pump. a molex connection and 16-18ga

is proper to run water pumps

I assumed the OP would run the pump with a molex connection if it had one? Then that cable would not be needed. And if he's running prefilled, than the gauge of that cable can hardly be "way under gauged" comapred to the copper on the mobo supplying the current to the pump and fan(s) under normal use. 

IF however OP's running say a Laing D5, the situation would be different, but to my knowledge there has never been any D5 or any other high performance pumps with 3-pin fan connectors, since they'd instantly fry the mobo fan header.

Ah, I see  Still at 18W max including fans, I see no issue running pump with above mentioned adapter.

At 12V( a relatively speaking "low voltage"), both the length of the wire, and the actual continous power draw decides the appropriate gauge, not the power draw alone. 

U = R*I (voltage= Resistance*Current) Considering how short the adapter wire is, at  ~1.5 amps max, I hardly believe the resistance of the wire to be a security risk, even if the startup current would be greater than 1.5 amps. If the length if the adapter wire were longer, say 3 feet, or the power draw was the same, but at  lower voltage, then it would be a different sceanrio.
