Your HP motherboard is not the typical Intel based board. All of the HP workstation motherboards I have worked with were never intended to be 'standard' with conventional ATX power supply wiring. Most of these were fine tuned as server quality workstations by HP engineers, without an intent to be equivalent to consumer grade personal computers. Whether that is good or bad is debatable, but it's what we have to work with. You can read up in this forum on all the toils and troubles members have gone through trying to convert non-HP power supplies into HP workstation-compatible power supplies. The best route, in my opinion, is always to find a HP power supply that is more powerful than what you have and is also certified for your workstation. Here's some tips, and you need to do the work from here, and then report back with your results so others can benefit: Read the latest QuickSpecs for the xw9400, 'power supply', and you'll discover that there was an older 800 watt power supply (part number 408947-001) and a newer 1050 watt power supply (part number 440860-001/442038-001). The part numbers are not in that QuickSpec, but I found them. I have an HP ProDesk 600 G1 desktop PC, and I'm upgrading it with a new graphics card and a new power supply. Now, the problem I'm having is that the motherboard in the PC doesn't have a standard 24-pin ATX power connector. Instead it has a 6-pin power connector and a 4-pin next to the CPU. One of my older computers has a 365-watt power supply that, for various reasons, cannot be replaced with a new power supply. I would like to upgrade the graphics card in that computer, but all the acceptable cards I can find demand the extra 6-pin PCI Express power connector. Set the power supply's voltage switch. If there's a voltage switch on the power supply, switch it to the 110v or 115v setting. This will ensure that your power supply provides ample power without damaging the components to which it's connected. Kenmore magic blue canister vacuum manual. Here's a quote from that document: 'Support note 1: May use two graphics cards using 1050W Power Supply. Some graphics card may not be supported in dual configurations with older, 800W power supply. Must use matching graphics cards and order a second processor.' Personally, I have mixed graphics cards when they say you can't and have succeeded. That has been with clean XP and W7 installs, not from HP clone CD/DVDs. So, knowing that there is a 1050W power supply I did a search, found the two part numbers, and using the second one I found a HP Parts Surfer image stating that it has two PCIe auxiliary (video power) connectors, instead of the single one on the 800W power supply. If you have two video cards each with a 6-pin PCIe auxiliary power connector then you should be good to go. Or, tap into both with a proper converter to feed power to a single high-power card. Here's the HP pic for the 1050W version, and note the comment about having the second PCIe auxiliary cable. Those two come straight from the power supply (intended for a second video card, generally) but they can be combined with special adapters to feed one even higher wattage video card in my experience, also: If you Google and eBay search for those two 1050W part numbers you'll see they resolve to a power supply that can drive your xw9400, or an xw8600. I found brand new ones for about 95.00. Best way to see if you have an 800W original is to open up your case and look at the side label specs on the power supply itself (or check for only one PCIe auxiliary 6-pin video card power cable present, instead of two). To spend 100 bucks instead of potentially frying your motherboard with a home-made power supply conversion sounds pretty good to me. Keep us posted! Thank you Scott for a massive input! To go further in this case i think I am ought to give you my current specs: My - PSU is the 1050w you are refering to, guess I am lucky. - OS is the Win7Pro that was preinstalled with the system. - Motherboard is the SP¤442030-001, AS¤408544-002 - Cpu: Opteron 2220 (one out of two possible) - GPU: Nvidia NVS 285 Now to the rest of the story. My intention is to get my Geforce GTX560 to work instead of the inferior NVS-card. The PSU has indeed got two black 6pin which i assume is the 6-pin PCIe auxiliary power connector you refer to. The GTX560 takes two 6pins to be correctly fed and at full load the card alone consumes slightly above 150w. I gave it a go and took the NVS card out and exchanged it with my new GTX560 and plugged in the two black 6pin connectors to the back of the card. Booted up just fine and since a allready had swept the drivers from the old card in safemode I proceded and installed new fresh (320.18-desktop-win8-win7-winvista-64bit-international-whql) drivers. It did not run for more than 20 minutes, regardles of the low GPU temps after a while I got a bluescreen telling me that some of the hardware was corrupt/damaged (do not remeber the specific term) I booted up again and the same thing happend. Also a third time and then instead of a bluescreen the whole computer froze with the desktop still on display and a had to shut it of the ugly way (hold the button) Now I am back with my old NVS-card and trying to solve this issue. I also got a note from the HP support telling me the same thing you did, and also that it might/might not work with a modern ATX PSU) It now feels as a long shot that the 1050w PSU should not be able to handle one GTX560. My assumptions are with your input in mind; 'they can be combined with special adapters to feed one even higher wattage video card in my experience' - have I completely foreseen something here? Should I combine the two 6pins first? Am I using the correct connectors? (can only find 2 6pins) Does it matter which order i connect the pins labeld P16 and P17? I did not have directx installed at the time, but that should not make the computer freeze right? My OS is of an inferior character? The two 6pins are on the same +12v rail? (On the PSU it is mentiod +12v-G1 and +12v-G2 so I doubt thats the case) Bad support for the GTX560 in the current motherboard BIOS? Faulty GTX560? (it was bought from second hand webiste similar to ebay but from Sweden) - I might be able to test the card in my neighbours computer Could I use a couple of 2xSata to 1x6pin adapters to get 4x6pins and then combine these into 2 more powerful 6pins? -Would that help anything at all? What are your current thoughts? My experience with the xw workstations does not include the xw9400 model, but things should be working from what you describe as the hardware/software. The latest QuickSpec document and the latest xw9400 Technical and Service manual are helpful. Here's a link to the latest manual (9th editon) for that workstation, and it includes info on the 1050W power supply: The two 6-pin connectors you found are in fact the PCIe supplementary power feeds intended for video cards. The convention is that 75W can be fed through the PCIe video card slot, and 75W through each 6 pin cable. So, for a card that can draw more than 150W there is either an 8 pin PCIe auxiliary connector or some cards have sockets for two 6 pin connectors (as yours does). In the xw6400 there is one conventional PCIe x16 video card slot (x8 electrical. 100%), and one PCIe x16 (x4 electrical. 50% power from the slot, so that's about 37W). Check the manual for whether you have such a situation in the xw9400. It will not matter what cable number goes into what 6 pin spot on the video card when you have two sockets for the two cables. Those cables are independent, and balanced at the power supply source, and should be fed in independently if there are two 6-pin spots on the card for them to go into. Here's more on the power issues: Sounds like a hardware problem to me. That power supply should be able to handle that card easily. For me when I'm doing troubleshooting I unplug all but the minimum, load W764Pro onto a small fast drive (you get 30 days free dinking per clean install before reformat needed with the OEM installer DVD. Just opt out of entering the code during the clean install) and see if things work that way. Then I add hardware back in sequentially. Maybe you have unbalanced loads and bunches of drives? Bad memory getting stressed by faster card? Scott Edit: Added info. In the xw6400 and xw8400 workstations we have put in EVGA versions of the nVidia GTX650, and most recently the GTX650 Boost. Not a problem with either version of those cards, both of which need a single 6-pin PCIe Auxiliary power cable.
