I'm looking to power 2 MCP655 pumps, 12 PWM LED fans, 1 SSD, 1 HDD, and 1 blu-ray burner connecting directly to the PSU's molex cables.
I'm trying to figure out how many amps that is. I used the watts / 12 method, so 177 watts / 12 = 14.75 amps. I've been advised not to exceed 18-20 amps per molex cable. It's really convenient to throw all of this hardware on a single cable with a couple pwm splitters and molex splitters. I guess I would feel safer putting the storage/optical on a seperate molex cable, but does it really matter? I mean, if something with the psu goes south, I have to assume everything's at risk.
The PSU is the Corsair AX1200, and the 18-20 amps per cable was recommended by ramguy.
Are my calculations accurate or am I way off in the total watts and amps for those devices?
The only thing left is to figure out lighting, and which to connect it to. Choice would be a matter of convenience now that I've basically split the backside into two zones. Front is molex 2 area, and rear is molex 1 area.
What wattage/amps are required for molex powered ccfl tubes? I'm thinking about a 6-12 inch single tube.
The cable isn't an issue so much as the connector. If you have all that daisy chained together with 4-pin molex plugs you'll have a big problem. There's too much resistance in the plugs and you can easily discover that by touching the first one in the chain while under load... it will be very hot.
I would feel fine about one cable per list, just not one molex You aren't going to draw too much power from the rail, the PSU will protect you there. But you CAN draw too much power through a single molex connection.
I'm sorry. Yeah I didn't mean a single molex connection, but single as in a single cable with 4 molex connectors.
The fans are broken into 4 groups of 3 with akasa splitters.
2x 3-fan splitters on one molex connector, and the 2 pumps on another molex connector.
SSD, HDD, blu-ray burner on a custom 3 SATA to molex connector on one molex connector, of 4, on this separate cable.
Then another 2 groups of 3 fans on the akasa splitters to another molex connector on that line.
