It's my first post so hello to everyone!
I just ordered brand new Mac Pro case to get my current setup installed inside of it. Box includes everything: case, fans, wiring, RAM riser cards and original PSU (980 watt).
Question is: can I use original PSU and connect it to my Gigabyte (GA-G31M-ES2L) board?

Hi village people and welcome,
If you are meaning can you use a mac pro psu, then no, not without modification. The pinouts are different and to make things more difficult, Apple did not colour code the wires either - they are all black. Having said that, a good voltage tester and some time could actually sort it out, but probably not for the faint hearted.

Hi Aqua and thanks for prompt reply  That's a pity cause I hoped I could use it without hacking. Seems I need to go and get voltage tester tomorrow. In the end it's going to be more fun One more follow up question though. Does this mean I cannot use the original SATA wiring either? Even if I decide to temporarily use other PSU? |

I just wanted to add that if you do start testing the Apple PSU, you should document your findings as others could use the info later. It might even be a possibility to make an adapter cable for Apple PSU --> ATX cable and sell them. I'd do it, but I don't have the Apple PSU to work with.

Would be really cool if you managed the PSU adapting.
The cables that come with the case would keep you from having to cut the PSU cables, effectively making an adapter.

pirloui: That's the plan. I'll measure voltage and try to just replace apple plugs with ATX type. After some reading though it seems that unfortunately I'll have to cut SATA cables

The only way you wouldn't have to cut SATA cables is if you have a SAS card nearby.

Not really (but I'm not sure if it will work). I'm going to get a cable SAS (socket) -> 4xSATA and try it. It costs about 50 euros but I think time needed for fiddling with cutting / welding is worth much more.

villagepeople, where did you find a sas socket to 4xsata adapter? All I've managed to find are 4xsata to sas plug (I think).

I believe villagepeople is wrong about a socket for mini-SAS, which is what we need, as they just don't exist. I've looked absolutely everywhere and found only cables with the same connector and sas cards. If you really have found one, post the pic of it here so we can see it and tell you whether or not it will work. I mean I'd love for you to have found one, but I just don't believe it until I've seen it.

I might be wrong. Didn't receive the case yet so I'm unable to check what kind of plug is it but I guess it might fit this socket. Picture attached. Attachments:

Please refer to this document: www.arrowce.com/binaries/1134744766182-E357_Molex_SAS.pdf as it will show you all of the available SAS connectors/cables and what they connect to. You'll notice that the only receptacle that works with the SFF-8087 in the Mac Pro is the Series 75783 with Shell. The problem is that these are connectors that connect to a PCB and don't seem to be able to make cables from. Theoretically, you could make an adapter board, but that would be expensive and time consuming. EDIT: I just found this which should work, but is still probably expensive. www.pc-pitstop.com/sas_cables_adapters/AD8788-1C.asp . It's basically what would go into an external RAID enclosure, so it takes SFF-8088 from the host which would be done using the cable below. www.computercablesource.com/sas-cable-05-meter-external-mini-sas-26-target-to-4-sata-host-1415.html . Make sure that the cable you get is SATA host/SAS target like the one I linked to. Theoretically, this should work, but it's going to cost you at least $65 USD or so. Is not cutting/soldering worth that much to you? |

@blackknight that pdf is really what people have been looking for , I think!
I think cutting and soldering do the trick. its all about Moding

Yeah, cutting and soldering really is the cheapest and easiest way to do it, but I do like the adapters and cable that I mentioned for a much cleaner look which could also eventually be easily connected to a SAS card with no cutting. If it wasn't so d**ned expensive, it would be the ideal choice, but alas. Anyways, until someone makes a combined version of those two things, it's still too costly.
