Hi all,
I work in a research lab and I need to change the GPUs of the dell workstation we use on one of our setups.
The new GPUs require way more power than the old ones and I'm scared the Dell PSU won't handle it.
The workstation is a Dell precision tower 7810 with a 825W Dell PSU. I've calculated the power needs of the new setup and these will be around 950W. Also the manual of the workstation (http://topics-cdn.dell.com/pdf/precision-t7810-workstation_Owner's%20Manual_en-us.pdf) states that the GPUs installed should not require more than 250W each. The GPUs I will be using (http://www.gigabyte.com/products/product-page.aspx?pid=5560#sp) may indeed require more: gigabytes exagerates saying 600W each...
Therefore, I have two solutions (this machine sits in a research labs therefore it is completely OK if it will have to stay wide open with custom-built extensions and cables everywhere):
1) change the PSU for the whole machine
2) use a second PSU only for the GPUs
Solution #1 would make more sense but I'm struggling finding precise information about the power requirements of the dell motherboard. I know that in some cases dell uses specific connectors and voltages and I do not want at all to burn my system. Does anybody has some information about this ? the only info I find online are for very old dell workstations and do not seem to apply anymore.
The motherboard has:
- a 24pin connector that I hope has standard wiring and voltages.
- two CPU power connectors that are 10pin (I figure that the standard is 8?)
Therefore, in order not to burn my system I would like to keep powering the motherboard and CPUs with the Dell PSU and use a separate PSU just for the GPUs. I mean only the 8pin extra connectors on the top of the GPUs. But the PCIe slot feeds power to the GPU too. Will this be safe or will I fry the GPUs? Of course the PSU will not be identical...
I'm really struggling understanding which is the safest option here. Any help is greatly appreciated!
