Got the new PSU hooked up, everything running nice and cool now. Thanks for all the help.

Thanks everyone, all of the responses really helped. I just bought a Seasonic X-750. It should be able to handle 4 of these rboxes without even sweating

I'm not trying to be rude, but I assume the one you're using was either fairly old, fairly cheap or both? It probably won't be hard to track down a half-decent PSU with at least 25A on the 12V rail. Look for 80+ Gold rating. I'd recommend a server PSU as an affordable option but the power output is overkill and if you're running R-Boxes you probably want something quiet - which you're not likely to find from server hardware. Fart around in the Computer Hardware sales forum (https://bitcointalk.org/index.php?board=75.0) and see if anything pops up. I bet some of this guy's stuff (https://bitcointalk.org/index.php?topic=958566.0) would meet your needs. Its actually a brand new supply, this one to be exact: http://www.thermaltakeusa.com/products-model.aspx?id=c_00002031 I do completely agree that I need a heavier gauge wire and that's what the problem is. The actual supply has no issue providing the wattage. I'm going to take a look at the supplied threads and buy something beefier. that psu is a multi rail piece of junk--- for your purposes. http://www.newegg.com/Product/Product.aspx?Item=N82E16817153165&cm_re=tr-500-_-17-153-165-_-Product I appreciate that because my only experience with PSUs has been with PCs and these miners obviously draw a lot of current. I'm going to ditch this and get something much better to fire up my second one. I think I'm going to go with one of the corsairs.

Bitcoin / Hardware / Need a PSU recommendation

on: February 28, 2015, 05:48:36 PM

Hey folks. I have a very simple setup, 2 Rockminer R-Boxes running 120Ghs each. The problem is I need recommendation for a PSU. When I run one of them, I can just use one of the two pcie 6 pins and its perfectly fine. When I want to add the second one, the problem is that the second pcie plug is on the same power lead, which causes far too much current to be pulled from that one lead and the wires get way too hot. I can use a dual molex to pcie 6 pin, but this is even worse since all the molex connectors are also on the same lead and the load problem is worse because molex only has 12v on a single lead. What I really need is a PSU that has multiple pcie 6 pins on different power supply leads and I can't find one. Anyone help me out?
