I do mean the paperclip trick, but the EGVA power supplies come with a connector, that basically does the same thing so you can test the power supplies to ensure they will power up. You can simply leave it in place and use the power supply.

Glad to hear you are up and running. In the future or when you upgrade you might want to look into getting a single Psu to run 1 or 2 machines. Depending in if you have 110 or 220 volt service.

Phil had some good advice on Psu's from parallel miner, and myself I like Amitylabs through their ebay store. They are a bettet quality Psu's meant for full service 24/7.

Do you mean the paperclip trick to tell the Psu to stay on, I remember stumbling upon it while googling information when I was looking at getting started.

Bitcoin FTW!

Parallelminer also has a nice coupon code "slush" right now for 5% off IIRC. The paperclip trick is easy to do but if you somehow can't do it people do sell switch like things that do the same thing. Here's how you can do it if you get a standard computer PSU: http://aphnetworks.com/tutorials/psu_paperclip_trick

Thanks!

I did misspeak - my 750 does have three separate cables(actually 4 I think but only need three for one side). But by weird coincidence an ex-PC repairman friend came by. After handing him a beer he looked at it. He thought that using the "daisy-chain" 6pins on the 650 for 2 of the 6 power connectors would be perfectly fine. With my fingers crossed we powered it up. Works fine and the infrared thermometer indicates no heat-up in the cables or connectors after about an hour.

So I am good.

By the way, for novices, it is not obvious that you need to connect the CPU cable, leaving the "tester" in place to wake up the power supplies. I put this tidbit here in the post for future searches.

I'm mining!

You did wrong you need six cables.

Three separate from one psu on the left side of the miner

Three separate from other psu on the right side of the miner.

Return them

Evga 750 p2 works has three separate cables

More efficient

And 2 of them are about the price

Short version:

My PSUs:

EVGA SuperNova 650G2
EVGA SuperNove 750G2

My Miner:
Avalon 741

What cables that came with the PSU do I use? The 8pinx2-6/2pinVGA?

Long version

I bought these two power supplies - one for each side - for my Avalon 741. I need six, 6 pin female connectors for power. The power supplies each came with two VGA cables(four total); 8 pin at the PSU end and two 6 pin connectors(one with a 2 pin breakout) at the device end. Can I use three of the the four available VGA 6 pin (ignoring the 2 pin break-out) connectors on each PSU as power for the Avalon 741? I am a software engineer, not a hardware guy. But I *think* this is the PCI I need as power for the 741. I would look on the Avalon web site but it is down for maintenance )-: Plus - I don't think they say. The video just shows a happy guy hooking stuff up - no real detail.

Connector size and gender is right and enough connectors - Just want to make sure this is correct(ie voltage, polarity, etc).

Thanks in advance for any confirmation!
