I originally found minerparts on this forum and ordered my first batch of risers through their ebay store after PMing fittsy on here.    I got them 2 days later (their inventory is in Texas which I like - I'm in Colorado) and soon after that I ordered a second batch.

On Tuesday of this week, I ordered my 3rd batch of the new "Version 7" with the 6 pins from them.   When I was ordering them, I mentioned it to Ben (fittsy here on the forum) that out of my last two orders, two of my risers were having issues.

This new batch arrived today with two free replacement ones included - no questions asked!

I want to thank MinerParts.com for being one of those quality companies that it is a pleasure to do business with.
Thanks Ben and Chris!



cheers,

p.s. here is a photo of the new version 7 riser on the left):

1800 watt UPSs are very expensive.
900 watt UPSs are not to bad.

Say you were running a rig on two 850 watt PSUs using an add2psu to trigger (and common ground?) them...

Is there any reason you couldn't run a pair of 900 watt UPSs to protect the rig - one on each PSU?

I have done some searching have found conflicting information; I've found those who are claiming all risers should be from the same PSU and I've found claims that each GPU should have its riser and its 8pin running off of the same PSU.

My situation:
I have two identical 850W EVGA G2 ("single" rail) power supplies.
I have an add2psu to connect/trigger them.

I am running a 7 GPU system.

Each Power supply has 4 VGA outs and 4 SATA/peripheral outs.

Picture of the actual outputs:  http://d13z1xw8270sfc.cloudfront.net/origin/367121/1452086810760_220-g2-0850-xr_xl_5.jpg

Does anyone know the best way to connect the risers & video cards using this setup?

Cheer and thanks in advance.

I would like to hear some opinions from those more knowledgeable than myself about what is going to happen when ETH switches to POS and all of a sudden thousands of mining rigs - 10's of thousands of video cards - move to other currencies (like zcash) to continue mining?

What impact do you think all of this horsepower is going to have on anything still GPU'able?

I'm building an LGA 1150 rig with 6 or 7 GPUs for zcash and ethereum mining. (MSI Z97 gaming 5 mb).

Is there a recommended minimum CPU speed or can I go all the way down to something like a $40 celeron with no impact on the rig's mining performance (dedicated GPU miner only).  For example would a $44 Celeron G1840 be fine or is there merit in performance impact in spending the extra and going to an i3 or i5?  I don't want to skimp on a $2000 rig with a $44 processor if it'll negatively impact mining - but I also don't want to put a $200 processor in it if it is literally wasted money as this machine will have no other functions. (I have plenty of other powerful machines here that are the "daily drivers").

cheers and thanks for the input. 

...or is the 900ms of latency too high.

Is there a way to mine with almost a full second of latency?
