Power supply for PR4100

[DoM76]

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!

PR4100 Power Supply

I understand the requirements of a PR4100 power supply are: 19 Volts 4.74 Amps 90 Watts But I also need to know the polarity of the centre pin of the DC jack and the diameter of the centre pin of the DC jack to enable me to source a replacement power suppy. Thanks.

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.
