Quadro 6000 died, can I install a GTX 1070 in this Z800?

HP Recommended
Z800
Microsoft Windows 10 (64-bit)

I have a Z800 that has a 825W PSU.  My Quadro 6000 died and I have a GeForce GTZ 1070 FTW that I'd like to use to get it going again.  The issue is that the connectors from the workstation are 6 pin ( I have two available) and the plugs on the card are 8 pin.  The only way to make this 'work' is using another HP adapter to go from 6 pin to 8 pin, but I've been told it will catch on fire, so....that's not ideal.  Is there no safe way to use this card?

Agdodge4x4,

 

The EVGA GTX 1070 FTW does require 2X 8-pin connectors and the nominal power draw is 215W. The PCIe x16 GPU slot provides 75W and if there are 2X 6-pin connectors present, the remaining 140W should not be a problem for 2X good quality (the ones with black and yellow wires are usually better) 6-pin to 8-pin connectors.  

 

It's interesting that the GTX FTW requires 2X 8-pin while the MSI 1070 Ti Aero ,  a slightly less highly tuned blower design and a number of other GTX 1070's including the EVGA GTX 1070 SC use a single 8-pin. The FTWt must be especially high performance.

 

Who suggested that a 6-pin to 8-pin adapter would cause a fire?

 

Be aware that a twin fan, open enclosure GPU will output more heat into the case than a blower design.  After installing the FTW, consider monitoring the CPU and GPU temperatures when under higher loads and if GPU rendering, consider raising the fan profile in BIOS. 

 

The change will probably be more than slightly noticeable. Average Passmark 3D scores:

 

Quadro 6000 = 2669

GTX 1070 = 13,386

 

 ^ Compare and contrast,...

Who suggested that a 6-pin to 8-pin adapter would cause a fire?

 


Another forum.  Multiple posters said the wires or adapters would catch fire.  

 

So, I figured I would ask the forum dedicated to HP equipment.  Yall know the equipment better than anyone.  I sure as heck don't want to burn the machine up.  There will be nearly no rendering or gaming use at all.  These machines are office machines now.  I just needed a decent card to get it running and this is what I had available to me.  But again, I am now afraid that putting two 6 pin to 8 pin connectors in will burn it up.

HP custom builds these to a higher standard than the ATX standard.  For the ATX supplemental PCIe graphics power cables those are rated to 75W each ("ATX standard")..  The card slot, PCIe x16 video slot, is also rated to 75W.  So, 3 x 75 = 225W.

 

However, the two PCIe supplemental power cables in the Z800 and in many of the other HP workstations are rated to a higher value.  As you will see from the Z800 power supply label attached below each of the two supplemental power cables is rated to 18A.  18A x 12VDC = 216W.

 

216 + 216 + 75 = 507W available to feed that card.  Not that you would want to be near the theoretical limit, but it is good to know that HP engineered in a significantly higher capacity.  That is why they also sell, for their supplemental power cable ends, a single 6-wire to two 6-wire adapter, and also a single 6-wire to 8-wire adapter.  Those are engineered by HP with thicker wires and the wires not stripped down in number.  The HP part numbers for those have been posted in the forum here and elsewhere.  Here is the label from the power supply with the two outputs representing the graphics power cables, surrounded by a red border::Two supplemental power cablesTwo supplemental power cables

If you can't find the 6->8 HP adapter part numbers you need let us know..... I have them stashed somewhere in my pile.  There are some good non-HP ones out there but most are not what you'd want.  I trust the HP ones....

So, the one 6 -> 8 Connector already used is a FOXCONN and the number is 460621-004 REV.F

 

I just bought another supposed HP connector on ebay that is a 6 -> 8 to go with it.  That part number is 460621-002.

 

So what you are all saying is that I CAN in fact use my 'dual 8 pin video card' on my z800 and not worry about burning my workstation to the ground provided I use the right connector....

 

EDIT TO ADD:  I see an older post where this is stated:

 

[quote]

Newest version is option part number N1G35AA = 683867-001

There was an earlier 460621-002 version.[/quote]

 

I cannot locate the NEW part number, but the one I got on ebay as well as the one already in the workstation seem to be similar in part number to the 'earlier' version.  Do you think these will be suitable?

Note the ferrite core under the heatshrink.  The option part alphanumeric got me to:

 

PROVANTAGE: HP N1G35AA 6-Pin to 8-Pin Power Supply Adapter

 

Which is a pretty good price for these... Provantage is a good company, and they won't be selling fake ones like you can see on eBay.  Your earlier ones sound good too.

 

Yes... you'll be fine with two of those true HP ones.

 the z800/z820 systems use "multirail" type power supplies, and the max amperage for each rail is printed on the power supplies label (which "SDH" posted) note that sdh's max power for GPU is dependant on installed cpu (low or high power) number of cpu's (one or two) and number of HD,s installed and number of installed dimms a fully loaded system can not use the 850 watt supply and requires the upgraded1150 watt supply

 

The DPS850DB A 850w power supply has 10 rails, while the DPS1050DB A has 11 rails. Each rail serves a purpose on the Z800's power supply, which is likely similar to the later Z820 and Z840 multi-rail power supply designs.

This is what each of the rails do on the DPS850DB A (850w) and DPS1050DB A (1100w):

• +12vCPU0: Provides power to CPU0 and CPU0's fans

• +12vCPU1: Provides power to CPU1 and CPU1's fans

• +12vM0: Provides power to memory on CPU0

• +12vM1: Provides power to memory on CPU1

• +12vB: Supply 3.3v and 5v (likely though a separate DC-DC converter) and system fans

• +12vS: Provides power to PCI, PCIe, and system fans

• +12vD: Provides power to storage drives (hard drives, optical drives, SSDs, and diskette drives) and input to miscellaneous onboard regulators

• +12vG1: PCIe auxiliary connectors Both auxiliary connectors on DPS-850DB A, one auxiliary connector on DPS-1050DB A

• +12v2: 2nd PCIe auxiliary connector DPS-1050DB A 1100W ONLY

• V12N (may be labeled as -12v): PCI and serial ports

• +5vSB: Sleep circuitry
