Hi, I have been the owner of a PR4100 for a few years and my power supply has died. My issue is that I have been unable to source a replacement in the uk as WD do not supply replacement power packs. Does anyone have any idea where I can reliably source one from please?
Thanks Dom
Check out the power output rating on the current one you have then search the web for something with the same rating… might even be cheaper!
this is also a common computer lap top power supply
I am using a pair of Dell PA-4E power supplies. They are rated at 19.5V 6.7A which is more than plenty than the 4.74A the OEM supply is rated. The two are more than enough, I like the redundancy. The Dell DC plug is size, pin and polarity compatible. I inherited the PR4100 diskless and w/o a power supply. Works like a champ now. I just moved on from 15 years in electronic recycling so those power supplies were another found treasure. I have been running the Dell supplies for over two years now, so they are a viable alternative.
Please excuse me, but I have to call you out on this post, especially the Dell DC plug size. I don’t know what kind of Dell power supply you have, but Dell is producing computers for at least the past 10 years with the 7.4mm x 5.0mm connectors with a pin in the middle, which DOES NOT FIT to the PR4100. Any Dell Dell PA-4E nowadays have the aforementioned 7.4mm x 5.0mm connector.
The image is for just reference, that to show the 7.4mm x 5.0mm size and shape.
The connector which fits is the 5.0mm x 2.5mm barrel connector.
My PR4100 power adapter I think has just died, all I’m getting is 4 flashing red lights on the 4 bays. Has anyone found where a reliable replacement adapter can be found online and from the UK?
if you keep the plug and some length of cable from the OLD power unit you will be ahead of the game as the power brick is 19 volts 4.74 amps DC center pin +
mine for the US units says Asian DA-90J19 100-240 V 50-60 HZ
high end laptops in years past used the same power brick
keep the DC plug in case the replacement unit has different size center pin
I have that problem even getting Amazon replacement power unit for Netgear ethernet equipment
