This is a really unprofessional
Its obvious that cards can't cool adequately, not enough space between them and why are they so high above the MB?
And why use 2 PSUs
, when u can use 1 only if you had the soldering skills, one PSU
is much more efficient, we are talking 100-200 wats.
Its not a bad rig, but it hasn't been though thru enough, and quite a lazy setup.
P.S. Its also obvious, that if someone tries to pick it up from the sides, and squeezes, they might break off, cause they are attached only at the bottom...
You are definitely not a mechanical engineer???
Just to post some comments & observations:
6 x GPU rig setup especially if using R9-390s does take on up to 300watts per card -so two units of 1300w PSU will do nicely with a comfortable buffer for OC.
1 x 1600w may do it too -- but probably safer on 5 x GPUs ; the AMD based cards are highly overclockable ....
2 x 1300w EVGA is cheaper than 1 x 1600w EVGA = so there is also cost considerations.
These 390s can run up 30MH/s easily with minor OC, and of course that will take even more wattage.
I understand these rigs are custom made for sale to clients - ShopemNL has a nice store front selling customs rigs (used and new) and mining accessories.
For online sales to customers, some level of quality of parts, PSUs, cost, etc will be major consideration for ROI vs ETH current market price.
This rig is also a very powerful mining machine for alt-coin mining, so there is life after ETH in the future...
Open rig case like these will need good powerful fans eventually to help get heat off the cards - this would probably be setup after rig completion when the rig goes into the data centre or home computer room / basement / attic.
The XFX cards have good quality active fans built-in so the gap in between cards is acceptable. The rule of thumb is gap of 1.5 inches, as per advised by rig owners that I have seeked advice from.
R390s are reputed to be best for high resolution gaming modes, versus the Nvidia equivalent GTX-970 which is another badass card for mining - so there
are active fans, VRAM up to 8GB etc to consider, etc... all these will require more wattage.
Welcome any comments, so that we could share information & keep it nice people.
