My company is building a server and we've already purchased an Asus Z8NR-D12 motherboard which we really like, but when we went to assemble our server, we found that the chassis we had bought came with a PSU that only provides one EPS12V connector while the motherboard needs two. We had some other problems with the chassis, so we're going to return it and get a new chassis and psu.

So can anyone recommend a PSU that will work well with this motherboard? I've been doing some searches, and I'm having trouble finding one that has 2 ESP12V connectors.

I guess another option would be a molex to eps12v adapter cable. But I'm not sure how well this will work when the server is under load. My understanding is that the eps12v uses 4 pairs of wire for a reason, and pulling all that current down the single pair of a molex connector could cause problems.

You can buy splitters that take one EPS12V and provide two connectors to the motherboard. This isn't ideal for a number of reasons, but it may be suitable for your situation.

I don't have any specific recommendations, but the key words you need to use in searching for suitable supplies are "Dual eps12v":



Original answer deleted, it was incorrect.

According to the manual, you will need a single 24-pin and all 4 +12v sockets filled in. Fortunately, google is your friend yet again, and was able to locate such a supply.
