  1. Thanks again & again LeDoyen 1. Prime Z790-P WIFI - See attached picture of motherboard box label (I'm trusting that ASUS didn't mix up a box and a device!) 2. I've put everything away in a closet to get to taxes. When I get back to the computer, I'll follow you guidelines. 3. Pretesting: I read and watched many, many water cooled build instructions prior to starting. Not one mentioned the (obvious now) need to test the setup first before adding any water cooling - sure wish JayZ 2 cents (think I got the name right) Corsair video had mentioned and emphasized this! It sure is obvious in hindsight. Hope you are still around in 4-6 weeks when I get back to this - will keep you apprised! Thanks again Doug
  2. WRAP-UP First - Thank you to all, especially LeDoyen, for the suggestions, answers, and brainstorming in this thread. Obviously, my attempted build is a $2500 plus failure. I must decide on the path forward. Right now, I'm leaning toward finding out which part or parts are failing. I won't be able to pursue this for 4-6 weeks - got to do taxes (to keep out of jail!) WORKING COMPONENTS (or likely working) 1. PSU: The RM850x appears to power the pump and all the fans 2. Hydro-X Pump: The XD3 RGB pump appears to circulate fluid. 3. Radiator: All 3 fans spin up 5. Fans: All 5 case fans (Incl. 3 rad) spin up. 6. Tubing: No leaks in all 6 tubing segments. 7. Fan controller: iCue Commander Core XT powers all fans and pump when connecter to the PSU. Note: No RGB function anywhere, but probably not expected QUESTIONABLE COMPONENTS 1. Motherboard: ASUS Prime Z790 WIFI a. CPU: Intel I7-12700KF - Need to disassemble motherboard to make sure pins didn't get bent! b. M.2 NVMe SSD's: Need to test 1 at a time. QUESTION: If the motherboard was good, would it "work" without any storage (SSD's)?? c. GPU: ASUS Radeon RX 6800 The following questions might be better addressed to ASUS however if anyone here knows the answers, I'd be very grateful! 1. I have a good spare ASUS Radeon R7 370 Strix Gaming GPU and could pull my ASUS Radeon RX570 to test out in the system - Would they work with the new motherboard?? (I haven't researched this, but will if no one here knows the answer offhand) 2. Would it be safe from a heat standpoint, to briefly power up the system with ne GPU cooling fan? Disassembling the EKWB water block would be a pain - nice if it could be avoided! d. Memory: Corsair Vengeance RGB DDR5 (32GB, 16x2) QUESTION: Can the motherboard be tested without any RAM?? Draining a fully water cooled system is a lot harder than filling it!!! I need to figure out a way to suspend the case, front face down over a large tub/container so that I can unscrew all the Hardline fittings and remove all 6 tube segments. This would let the water drain without wetting any components. Thanks again for your assistance! Doug
  3. This is a brief reply to the 4 pin motherboard connector labeled "ATX_12V_2" discusion 1. The RM850x PSU box did not contain any - "you should have other CPU 8pin cables. the motherboard end of the cable splits into two 4 pin connectors" - cables that split into 2 4 pin connectors. 2. I'm assuming that the 4 pin motherboard 12V connection should remain EMPTY. That is how I'll proceed (Nothing has ever been connected there during testing.) I'm now preparing a wrap-up note which will contain a few important questions about the way forward. I will not be able to pursue this for at least another month - have to get on taxes! I'll post the note when it's completed on Notepad.

    New Hydro-X system

  5. 1. Additional Question: My motherboard has empty 4 pin "ATX_12V_2" next to the connected 8 pin 12V socket. The PSU has no corresponding connector No applicable cable was supplied. Please confirm that nothing should be connected to that socket?
  6. MORE TESTING - Results I was just about to put the build away for a month while I got to taxes, however.... Setup: RM850x Motherboard: 18pin & 10pin cables connected to Corsair shunt cap PCIe/CPU: 8 pin connected to motherboard "ATX_12V_1" PCIe/CPU: 8 pin connected to GPU (I've read numerous recommendations not to use 1 cable and pigtail???) PCIe/CPU: 8 pin connected to GPU SATA/PATA: 6-2 pin connected to XD3 RGB pump SATA/PATA: 6-1 pin connected to Commander Test 1: Tried a single Corsair RAM in the recommended slot (alternated both of my Vengeance RGB DDR5 16GB's) with all PSU connections Result: All 5 case fans spun up, pump started after about 3 sec. Note: Loop has no air bubles, initially thought pump wasn't working so I removed the top cap on the pump - water started vibrating after about 3 secs. Further tests were done with no RAM Tests 2: I removed all PSU connections except the 18/10 pin connected to the shunt and the 6-2 pin connected to the pump Result: Heard pump start up after about 3 sec, no running fans (fan on PSU runs slowly for about 10-15 sec) Test 3&4: Added the 2 PCIe/CPU cables to the GPU Result: AH HA! Difference A guess - whenever I added a device (GPU or Motherboard 8 pin to any PCIe/CPU PSU slot the pump sound went away but the water kept vibrating slightly - appears pump at max can be heard, adding device puts pump at lower speed??? Test 5: Added 6-1 pin SATA/PATA connected to Commander Result: All 5 case fans (includes the 3 radiator fans) spun up plus pump General conclusion: Sadly, things are pointing to the motherboard!!! Getting to this will be a major project in a water cooled system!! Hindsight! 1. I probably should have gone with a larger case! I thought by eliminating all hard drives, CD, DVD's and regular SSD's a smaller case than my existing large Obsideon case should work! As it turned out, the extra room would have helped (esp. with my 80 yr old clumsiness) 2. For anyone! I should have put together all my components without any water cooling devices added. Then powered up the system to check all basic hardware. Then loaded Windows. After success, start adding water cooling components very, very carefully. Be especially careful with CPU - maybe document steps with pictures! ain't hind sight wonderful!!! TIA - Doug
  7. AARGHH!! FAILURE I slept well last night thinking you had found the real problem - not connecting the 8-pin 12V connector to either the PSU or motherboard - stupid me! When I did the above connection this morning, I had high hopes! DASHED Turned the power on - nothing! absolutely no sounds anywhere! A month ago when I had the RM750x installed, the same exact thing happened after doing successful 24 hr. leak tests. At that time, I put the system back into leak test mode to see if pump would still work - it did not, so for that and other reasons, I thought I had a defective PSU. Now, maybe not??? "But make sure the SATA power to the controller is also connected, and that this dangling USB connector is insulated with its plastic cap or else you risk shorting 5V to ground if i touches an ything metallic." The male connector has always had its protective cap on. SATA is connected to the supplied 3 connector PSU cable which is plugged into a PSU SATA slot. The Commander's USB cable is connected to the motherboards labeled "USB_E12" USB2.0 header. Connections: On motherboard (Asus Prime Z790 WIFI) in clockwise direction 1. 4 pin "ATX_12V_2" EMPTY 2. 8 pin"ATX_12V_1" connected to PSU (8 pin PCIe/CPU PSU output) 3. 4 pin "CPU_Fan" EMPTY 4. 4 pin "AIO_Pump" EMPTY 5. 4 pin "CPU_Opt" EMPTY 6. 4 pin " RGB header1" EMPTY (for Aura) 7. 4-1 pin "ADD Gen2_1" EMPTY (Note ADD=Addressable) 8. 24 pin "ATX_PWR"connected to PSU (18 pin Motherboard output & 10 pin Motherboard output) ???24 pins 1 end 28 on other ???) 9. 20-1 pin "U32G1_78" USB 3.2 Gen 1 header EMPTY 10. ? pin "U32G2_C4" USB 3.2 Gen 2 Type-C front panel connector connected to front panel case cable. 11. 14-1 pin "TPM" EMPTY 12. 4 pin " RGB header2" EMPTY (for Aura) 13. 4-1 pin "ADD Gen2_3" EMPTY 14. 4-1 pin "ADD Gen2_2" connected to GPU EKWB water block 15-18. 4 SATA 6Gb/s ports EMPTY (system is all M2 SSD's) 19. multi-pin System panel header (I purchased a plug with 6" wires to RESET, PLED, PWRSW,Speaker - more accessible) 20. 20-1 pin "U32G1_56" USB 3.2 Gen 1 header connected to case USB 3.0 front I/O connector ???3.2 to 3.0??? 21. 10-1 pin "USB_E34" USB 2.0 header connected to Commander USP cable 22. 10-1 pin "USB_E12" USB 2.0 header EMPTY 23. 2 pin "CLRTC" clear CMOS header EMPTY 24. 4-pin "CHA_Fan3" header EMPTY 25. 4-pin "CHA_Fan2" header EMPTY 26. 6-1 pin unknown header (next to Thunderbolt header) EMPTY ???? not listed in motherboard manual or on web 27. 14-1 pin "TB_Header" EMPTY 28. 10-1 pin "COM" COM Port header EMPTY 29. 10-1 pin "AAFP" Front panel audio header connected to case audio cable 30. 4-1 pin "S/PDIF OUT" header EMPTY 31. toward center of MB 4-pin "CHA_Fan1" header EMPTY Your thoughts - wife thinks I was crazy attempting this!! TIA Doug
  8. FAILURE!!! 1. I ran the leak test successfully. Hydro_X pump purred along nice and quiet. 2. I then hooked 2 GPU leads to PSU. The GPU is an Asus TUF Gaming RX 6800 with a EKWB water block (Corsair didn't make one). Removed the Corsair supplied shunt for the main motherboard cable, then attached that cable to the motherboard. Checked all cables and wires. Then prayed!! 3. Turned power on at the PSU, the center fan on the radiator spun up very briefly, then stopped. Otherwise-total silence.. Flipped the PSU swith to off - waitied 20 sec, then flipped the PSU switch back on - central radiator spun up again briefly (few secs) - otherwise nothing. Tried thecase power switch - nothing! QUESTIONS: 1. Should the Commander Core attach to 1 or 2 USB2.0 headers It has an additional female plug coming off the first 2.0 plug. I've just let in "dangle" with its cover attached. 2.Does the fact that only 1 of my 5 fans briefly spins up tell you anything? (My pump is connected to position 6 in the Commander) 3. Do you have any ideas??? HELP!!! TIA Doug
  9. No leaks after 90 min - still purging minor air bubbles from the loop. Fairly complex loop - GPU,CPU, 2 M2 SSD's, radiator, pump - I cut out 2 of the hexagons in the case top grid to allow me to add a 3 foot fill tube into the top of the pump. Made filling system much faster & less messy. This is probably my last build - I'm 80.
  10. Thanks again for the very prompt responce. I'll extra protect my PSU when leak testing my custom Hydro-X loop (which I'm about to do! - wish me luck!!)
  11. I've been reading a lot of past power supply questions - in one, you (LeDoyen) suggested turning the PSU so that the fan was pointing into the case. Is that the suggested corect orientation for the PSU???

  13. 1. Should the fan in the power supply come on when the unit is plugged in with no output connections? 2. The covers on 2 new RMnnnx power supplies appear to be upside down as compared to published pictures and logic. "Logic" meaning that when installed in a 4000D case the correct way (fan pointing down towrd the bottom filter) the printing "RNnnnx" is upside down when the case is standing on its legs. Seems odd??? The covers in question are held on by 4 screws, one of which has a safety sticker. If the cover was turned 180 degrees, then the wording would correspond to published pictures. Anyone else notice this???
  14. LeDoyen - Many thanks - especially for the quick responce!!!
  15. I have a new DIY Hydro-X water-cooled build with Corsair fans, PSU, RAM in a Corsair case. After completing a 24 hour leak test, I would like to test my fans and PSU. The fans need to be connected to the Commander Core XT. QUESTION: How do I load the iCue software before I load my Win11 OS? Is there an iCue software version already loaded into the Commander Core? TIA Doug
