2nd HDD no power

CrimsonCynder · 18 Oct 2021 at 17:06

Recently bought a new PC from Overclockers.

Motherboard: Asus PRIME-A II
Power Supply: Kolink Modular Power 700w 80 Plus Bronze
SSD: WC Blue (WDS500G2B0B)
[If you need any other specs let me know]

I didn't get any HDDs as I already had 2 from a previous build. The one with windows worked straight away however my WD Blue 2Tb (WD202EZRZ) will not power on in the new setup. I do not have it in SATA ports 5 or 6 due to the M2 being installed.

I have plugged the power into an old computer PSU and the SATA into my new computer and it read it. However, if it's plugged into my PSU it will not power on, this means it won't show up in the BIOS or disk management either. I have tried the wires from my other HDD which is working and that didn't solve the issue and the working HDD powers on and is found on any of the wires so they're not faulty.

Is both hard drives connected to the same cable or the other hard drive an m2 ?

I have tried both with and without connecting to the same cable and the issue still happens

Do you have Molex to SATA adapter available?

Might be about that Power Disable feature and drive not powering because pin 3 gets 3.3V

Thats strange especially as it works if you use your old psu, do you have a molex adapter to try ?

I don't have one to hand but could order one if that's a possible fix?

Worth a try.

Thanks ordered one from Amazon, should be here tomorrow. Will it be fine staying in a molex permanently or should I be looking to update my HDD to transfer data after I finally get it working again?

Should be fine its just odd it works with your old psu, you can always do a health check on the drive .

Its a strange one for sure.

HDDs have never used 3.3V for anything and work perfectly when powered from Molex.
(don't think even SSDs use it, because have seen power draw figures only for 5V)
In fact leaving those 3.3V pins of drive's SATA power connector "floating" is what prevents that Power Disable feature from being enabled, which happens if PSU feeds 3.3V to that pin.

That Kolink garbage might well be older design than "old" PSU.
Power Disable feature was added in SATA 3.3 published five years ago.
While that Kolink was likely designed dozen years ago and with minimum care.
