So i want to power a 3TB WD Green 3.5 inch hard drive (WD30EZRX)
Power Management 12VDC ±10% (A, peak) 1.73A
Average power requirements (W) Read/Write 4.1W Idle 3.0W Standby/Sleep 0.4W
The before in the laptop was 500GB WD Scorpio Black (WD5000BPKT)
Power Management 5VDC ±10% (A, peak) 1.15A
Average power requirements (W) Read/Write 1.75W Idle 0.8W Standby/Sleep 0.2W
on sata power port of a laptop motherboard asus pro50rl (spec Pentium T2370, 2GB OCZ DDR2 800 RAM, Radeon Xpress 128 MB)
Spec of the laptop power supply
Model SADP-65KB B
INPUT 100-240V ~ 1.5A (50-60Hz)
OUTPUT 19V - 3.42A
Efficiency level: IV
Spec of the hard drive enclosure power supply (wd my book 3tb enclosure)
Model KSAS0241200150HE
INPUT 100-240V ~ 0.6 A (50-60Hz)
OUTPUT 12V - 1.5A
this power supply was powering the hard drive and the sata to usb3 controller board 4061-705094-001
here is a pic of the way i was running this before. it worked fine for years but now i want to power it even more efficiently just by using the laptop power supply. before i was running the hard drive in the external enclosure and 3 power supplies one for the cooling fan, one for hard drive and one for the laptop so my question now is can i power the fan and the hard drive without frying my laptop power supply/board or i am being too optimistic?
The laptop power supply was taking 15W power draw on my watt meter before on normal usage so not even close to 60W of the spec of it but the real problem is Amps so what do you guys think will this work or i am just dumb?
Does the laptop motherboard sata power port even supply 12V?
