OK, so I have picked out a case. now I need a Power Supply. I am looking for information on what kind to get. It has been at least 20 years since I assembled a PC myself. So, what wattage should I get? Are there any brands that I should go for or any I should avoid. Also, does anyone know how many pins on the power connector? Is it 20 or 24? Trying to get all this together before the mobo etc arrive so I am ready to go when it gets here.

Thanks guys.

Any modern PSU will do. The power consumed by the Amiga motherboard is trivial and your graphics card will probably consume more. The smallest you will be able to get will probably be 500-550W, which is ample. A big graphics card won't need more than 150W, and the motherboard needs no more than 20W.

All PSUs these days have 24-pin cables for the motherboard. They also have the last two rows of the connector removable so that you can use the same connector with older motherboards.

I have seen lots of different connectors for the graphics card power, so make sure that the connector on your PSU will fit the graphics card. There are six- and eight-pin connectors, sometimes even twin four-pin connectors for the external 12 volt supply (yellow/black wires).

Good luck with your project. It sounds exciting!

Buy a quality brand its worth it in the end, saves you lot of trouble.

What is currently considered a quality brand? Like I said, been about 20 years...

@DFergFLA

I've been really happy with BeQuiet. The latest one I bought was this:

https://www.bequiet.com/en/powersupply/dark-power-pro-11/761

- in the 650W variant.

But there are many good ones out there, just stay away from the cheapest Chinese (or similar) ones.

Best regards,

I had more or less settled on a cheap brand (about $50 each) for my projects. On opening one of the first I bought, I discovered that it actually had an iron-cored inductor inside, presumably to improve its form factor under heavy load. The inductor was wired in series with the mains supply, but I found a blob of solder across the PCB connector, so the inductor was deliberately shorted out. I removed the solder and it worked OK, so I left it like that.

In later PSUs, I continued to un-short the inductor without problems. Skip a few generations and for the last one I built, I bought another of these cheap PSUs. This PCB had a wire link across the inductor's connector, carefully hidden behind the connector and covered with hot melt glue so that it wasn't visible. When I finally managed to cut the link, I found that the PSU no longer worked.

After some investigation, I discovered that the "inductor" had no wire inside the winding. The two blue wires "connecting" the inductor to the PCB are actually solid PVC, with a normal plug on the end and carefully crimped pins. The "inductor" end of the wires is simply a loop of the PVC under the "winding". The "inductor" is carefully made with a printed part number on the outside. but completely bogus.

This deliberate deception makes me wonder how much more undiscovered fraud there is in the industry. In this case the PSU has a CE tick, so I presume that the deliberate fraud is an attempt to keep the CE rating.

If you look closely at the CE mark, it is probably a bit different than what you'd expect - it's the "Chinese Export" mark, which is a close, but not exact, match of the CE logo :)

I can second Nils' recommendation as regards the BeQuiet! PSUs. In my Sam440ep-Flex I have a BeQuiet! Pure Power L7 300W, which has been working reliably for eight years. For the X5000 I got a Pure Power 10 400W, which is now in its second year of service. It's got enough power to drive the mobo, two SATA drives, a soundcard, and a 45W Radeon Polaris card.

“Corsair” seems to be a serious company, I own a RM750, like the other brand that was recommended it, has the ability columnize cables, something I think is really nice, it has not failed me yet, and had it many years now.

The RM750 has a 10 years warranty.
