Fuse for PC Dell OptiPlex 5040

[Barney1234]

I have come across an old PC that I would like to turn on. However, before plugging in an IEC lead into it I want to make sure I have the correct fuse. (Using a 13amp IEC lead - UK)

Below are my findings. I am a bit confused as to what is being shown and what to do from a safety point of view.

When I look on the Dell website specification for the Dell OptiPlex 5040 it states that the power wattage is 240W.
Using Ohm's Law for Amps, I get the Amps to be 1 amp.

So I would have thought using a 3 amp fuse in the plug would be sufficient (and safe)....

However,

I then see on the side of the PC there is a sticker that has various symbols and text and I see on there it is showing:

V: 100-240V
A: 3.0A
Hz 50/60Hz

Attached is the full image I am seeing in case I have missed something.
As you can see it is shown in 3 parts ( I am looking at the top section marked in a red box)

My question is, what goes in the IEC lead.... do I now use a 5amp fuse?

I understand it's best practice not to use a fuse that is similar to the amp rating (so in this case a 3amp fuse as shown on the sticker) but the next fuse above (5amp)

When it comes to stickers and PC's that will have this sticker on, which rating do you go for?
The Dell website showing the power information, or the sticker showing that information on the PC?

I am in two minds as to use a 3 amp fuse or a 5 amp fuse for the IEC lead?

Any advice would be greatly appreciated (and peace of mind).

Small PC's will run on a 5 Amp fuse, there is always a small surge when you turn them on. The fuse is actually there to protect the cable so you may find they are fitted with 13A fuses as standard.

Thanks for the reply. Over the years IEC leads have gone astray or not needed anymore and indeed I have come across 13amp fuses.

Can you confirm what it means in the attached image though in red? Do I go with the Dell website or the sticker for the fuse rating?

Am I correct / safe for putting a 5amp fuse in the IEC lead from looking at the sticker?
