Re: [CLOSED] - GROUP BUY of BITFURY Chips + DRILLBIT SYSTEM mining assembly

Any word on powering multiple 8 chip boards through the mini plane? I think I saw it uses an ATX connector, so I'll need a Desktop PSU to power it? And the OP mentions ~0.8W/GH - so if I rounded to 3W/chip i'd be under 50W for 2 boards right? Will a 430W PSU be enough power?

Thanks,

Yes it the miniplane will be powered by an ATX connector so you will need a psu for it. And each board will use about 20-25W each from a rough estimate at the full 2.7GH/sec. So your 430W PSU will have enough power it could infact power 8 boards and still have leftover power.

If its a SINGLE rail PSU.If its a multi rail type,you could be in trouble by overloading one rail unknowingly Roll Eyes

Get a Single rail PSU,please!!! Wink

& keep it underpowered by 20% to keep it running cool.IE,500 watt PSU,only use 400 watts or so Wink

Personally,I'll be useing only the PCIExpress cables with adapters I'll make myself Cool

Why single rail and not multi-rail?

How can I tell if a PSU is single or multi rail?

My plans were to use a dedicated brand new PSU for my drillbits, with nothing else plugged in,and I've only got 2 boards coming so that shouldnt be too much for the PSU..

Well,not many PSU makers identify what cables are on which rail.PCIExpress are on rail #1,4pin molex on rail #3,etc....You can overload a rail very easily,with single rail all the 12volt cables are supplied by ONE rail,you know exactly how much power you can draw,its on all cables that give 12volt Grin

Modular PSU's are great,some even sell extra cables (Corsair,Silverstone I know do) that allow you to connect PCIExpress cables instead of say 4pin molex or even SATA power cables,you have more choices & expansion capabilities Wink

Just one example:

All manufacturers will or should state whether single or multi rail in the description,if not then assume its multi rail & move on.
