HRAW Posted September 28, 2008 Share Posted September 28, 2008 I just order a HX1000 PSU and they will be delivering to me this Sunday 09/28, but I would like to clarify some doubts that I Have at this time regarding this Model PSU: 1º) is the HX 1000 fully compatible with the ASUS P5K Premium black pearl edition. 2º) The Cooler Master CM 690 Case is made so the PSU go in the bottom part of the cabinet with the PSU fan seating down towards some pre-drilled fan intake holes, after the PSU is in place, there is a space between the PSU Fan and the bottom of the case of about 4 to 5 mm (0, 4 to 0,5 cm), I know that due to the length of the PSU I will Have to eliminate the bottom 12” fan that I have, but the PSU 14” fan will not match exactly with the bottom pre-drilled holes, I would like to know if that can be a issue compromising the airflow to the PSU intake vent or if the 0,4 cm will be enough for the air to circulate and cool the PSU. Also I would like to ask if it will be better to mount the PSU upside-down with the fan facing towards the inside of the CM 690, I have enough 12” fans with 90 cfm and a Thermalright 120 extreme with two 12” 90 cfm fans on a push/pull set up, on the side panel, I will have a 12” Fan that will be blowing cool air directly towards the PSU and the Video Card (8800 GTX OC) so I do not think that hot air blowing inside of the PSU would be a issue, I just want a recommendation from the people from Corsair and I want to make sure that will not be a problem to mount the HX 1000 wit the Fan facing up. 3º) Can I use a PSU extension cable with the original PSU power cord? I have being using one with my cooler master M620 with no problems, but due to the power of the HX 1000, a would like to confirm if it is ok. 4º) I would like to confirm in which rail the fixed PCI-e cable is connected to, if it is 12V1 or 12V2, looking at the configuration on the back of the PSU, I would assume that it is connected to the 12V2 Rail. I would like to apologize for my English and for the extent of this post.:(: Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted September 29, 2008 Corsair Employees Share Posted September 29, 2008 1º) is the HX 1000 fully compatible with the ASUS P5K Premium black pearl edition. Yes! 2º) Can I mount the PSU upside down? Yes, but as long as you have some space beneath the PSU for air to circulate underneath it, then there may not be a reason to. 3º) Can I use a PSU extension cable with the original PSU power cord? I have being using one with my cooler master M620 with no problems, but due to the power of the HX 1000, a would like to confirm if it is ok. Yes that should be fine, but the cables on our PSUs tend to be longer than others, so you may not need to use it. 4º) I would like to confirm in which rail the fixed PCI-e cable is connected to, if it is 12V1 or 12V2, looking at the configuration on the back of the PSU, I would assume that it is connected to the 12V2 Rail. Confirmed! The fixed PCIE cables are coming from the 12v2 rail. Link to comment Share on other sites More sharing options...
HRAW Posted October 1, 2008 Author Share Posted October 1, 2008 Dear Ram Guy, Thank you very much for your help. I would like to know what will be the minimum space necessary to circulate enough air into the HX1000. In the Cooler Master M690 after installing the HX 1000 with the Fan facing down, the space will be around 4 to 5 mm (millimeters) max and the pre-drilled holes will be really off center. Do you think that this space will be enough? Taking in consideration that the holes are off center. Sorry for the insistence on the vent and space issue, but I am really worried due to the general investments made in this PC. Thanks HRAW:confused: Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 1, 2008 Corsair Employees Share Posted October 1, 2008 I would suspect that 4-5mm would be enough space, as long as air is able to circulate into that space. I would install it right side up and stress the system for a bit and see how hot the PSU gets. If it seems hot to the touch, then try flipping it upside down, and see if you get better results that way. Link to comment Share on other sites More sharing options...

If it seems hot to the touch, then try flipping it upside down, and see if you get better results that way. Dear Ram Guy, Just to finish this thread I decided to post here the final results from my tests according to your recommendations: PC Configuration for the test: P5K Premium Blk Pearl Edition; Q6600 at 9X356 (3.2 GHz); Thermalright Ultra 120 Extreme with two 120mm 90Cfm fans (Push/Pull setup) ; 8 GB Viper 8500ELKR2 at 1069 MHz, Two Raptors X Raid 0; Two 750GB Samsung on Raid 0; 8800 GTX; LG Blu-Ray Super Multi Drive; DVD Super Multi Drive; 6 additional 120mm 90 CFM fans (Intake: two on the front; one on the top, exhaust: one in the back; one on the side; one on the top) (Well, noise it is not a problem for me, I like the sound of the V8 engine), Cooler Master CM 690 (PSU fits on the bottom of the case).(One of the Best cost/benefit case in the market, even better than the Cosmos Case (to big, almost 3 times the price)). Ambient Temp.: 22°C First test: HX 1000 Fan facing up towards the inside of the CM690 Idle for 2 hours: PSU: warm to the touch MOB temp.: 28°C CPU Temp.: 29°C GPU: 63° C +3.3V: 3.26V + 5V: 5.02V + 12V: 11.98V + 5 Vsb: 4.95V HX 1000 Fan facing up towards the inside of the CM690 Everest Ultimate Stress test for 3 hours: PSU: Hot to the touch MOB Temp.: 31°C CPU Temp.: 53°C GPU Temp.: 67°C +3.3V: 3.26V + 5V: 5.02V + 12V: 11.98V + 5 Vsb: 4.95V Second test: HX 1000 Fan facing down towards the bottom of the CM690 pre-drilled exhaust holes, Idle for 2 hours: PSU: Cold to light warm to the Touch MOB temp.: 28°C CPU Temp.: 28°C GPU: 60° C +3.3V: 3.26V + 5V: 5.02V + 12V: 11.98V + 5 Vsb: 4.95V 2º test: HX 1000 Fan facing down towards the bottom of the CM690 pre-drilled exhaust holes using Everest Ultimate Stress test for 3 hours: PSU light Warm to the Touch MOB Temp.: 30°C CPU Temp.: 53°C GPU Temp.: 65°C +3.3V: 3.26V + 5V: 5.02V + 12V: 11.98V + 5 Vsb: 4.95V Findings: You can see that there is not too much difference on Voltage and temperatures on the sensors, the only difference was that with the PSU facing down towards the pre-drilled holes taking cold air from outside, left it cooler to the touch when compared to the fan taking hot air from inside of the Case (PSU very hot to the touch in the last case). The final result was a MB 1°C cooler and a GPU 2° cooler on the stress test, also during the stress test even with the same overall CPU temp; I notice that the top individual core temp was 2°C lower. On Idle the only significant difference was that the PSU was really cool to the touch and the PSU fan was blowing cold air to the back. Also keeping the Q6600 at stock speeds kept it 4°C cooler on Idle and 10°C cooler after 3 hours of stress test. I Also would like to comment that I am very impressed with the PSU performance, it did not have any fluctuation during the test, keeping all lines steady at all times, a bit different from my C. Master M620 that had a little fluctuation on the 12V Rails during the same tests. Hope it can be of some help to others.
