What about these?https://www.amazon.co.uk/dp/B075DWKSFB/_encoding=UTF8?coliid=I2E9UW7T3YJBBG&colid=1MHHB9ZYW5574
Sorry, I have never use this particular brand of leads. They may be fine for your multimeter. But they're not made for power supplies.
Leads for power supplies, should be rated at 10A are better. They should have unshielded Banana jacks. The ones you're looking at will not plug in to your power supply without either removing the lug nut, or cutting the shielding off the lead, not recommended. the best test/power leads, are expensive. Some are gold plated for the best connection. But I don't think you need to go that far.
this is the kind that I use.
They are made of 18 gauge copper wire, with heavy-duty alligator clips. Avoid the ones that have a rubber cover over the alligator clips, the cover tends to interfere with the closing of the alligator clips. they also come in multiple colors. I have 2 sets of 5 colors, One with alligator clips on one end and another with banana jacks on both ends. look around, I'm sure you can find some in your part of the world.
Good luck.
