Title: Any potential issue powering an L3+ with two EVGA PSU? Post by: Stockypotty on September 27, 2017, 09:20:36 AM Looking to get two of these: https://www.amazon.co.uk/gp/product/B017RO39TK/ref=ox_sc_act_title_1?smid=A3P5ROKL5A1OLE&psc=1
In order to power my L3+ (and overclock so need higher watts). Is there anything obvious i'm missing as to why this won't work? Thanks in advance for any help :) Title: Re: Any potential issue powering an L3+ with two EVGA PSU?

Think it's the VGA and the SATA ones. Title: Re: Any potential issue powering an L3+ with two EVGA PSU? Post by: Merlig on September 27, 2017, 10:03:15 AM You have to switch the power supply on via the ATX connector.
The signal "Power Supply On" must be connected to ground to start the power supply. Title: Re: Any potential issue powering an L3+ with two EVGA PSU?

But otherwise all ok to use two PSU for one system? Title: Re: Any potential issue powering an L3+ with two EVGA PSU? Post by: Merlig on September 27, 2017, 10:16:41 AM I have no L3 still waiting for the delivery, when I looked to the pictures there are 4 boards.
Use two boards with the first ps and the other two with your second ps. Title: Re: Any potential issue powering an L3+ with two EVGA PSU? Post by: QuintLeo on September 28, 2017, 12:20:23 AM From a power standpoint, those 2 PS should work fine.
Higher-end EVGA power supplies some with a "power test" adapter that is basically a "turn the thing on" plug that plugs into the ATX power connector, works well in a mining rig setup. I'm NOT sure if the GQ line includes that adapter, all of my EVGA are G2 models (I refuse to own any more PS with a "sleeve" type fan bearing, no matter how fancy a name they put on it they ALL die too fast in a high temp environment). Title: Re: Any potential issue powering an L3+ with two EVGA PSU? Post by: Phantoms001 on September 28, 2017, 02:57:31 AM Why not just go with a server power supply with a breakout? You can find them on ebay a lot cheaper and more efficient than running 2 power supplies.

When you connect PSU 1 goes to controller board and then to first hashing board only. second PSU would be connected to remaining hashing boards. Never connect more than 1 PSU to a single hashing board.

But otherwise all ok to use two PSU for one system? Minor detail: Most EVGA PSUs have one color for the entire cable, so you'll probably have to check a pinout diagram carefully to use that trick. Some of their PSUs also come with a "power-on self-tester," which is essentially a fancy plug just for this purpose. Title: Re: Any potential issue powering an L3+ with two EVGA PSU?
