GrenadaV Posted October 28, 2018 Share Posted October 28, 2018 Hi, I have installed a new AX1200i to my existing PC to run a RTX2080 Ti. After installing and connecting the PSU, some fans run super fast. So I have now disassembled the PC again and am trying to figure out why this could be. After taking it apart again, I started checking the cables and counting the pins. My MB has 24 pins, however the PSU that came with the PC, has a 22 pin connector for the MB. 24 pin connector but only 22 occupied. However the AX1200i PSU has a connector that is also either 20 or 24 pin, but it only has 23 occupied. Could this be the problem? if not, how do I best diagnose the issue and figure out if it is the PSU or not? appreciate some help kind regards Rossco Link to comment Share on other sites More sharing options...
DevBiker Posted October 28, 2018 Share Posted October 28, 2018 No, that is not the problem. The ATX connector is fine. My guess is that you are seeing the heat from the GTX 2080 Ti getting dumped into your radiator and that's heating the radiator up. Information like your coolant temperature would be helpful. Also, filling out your system details will help tons as well. Link to comment Share on other sites More sharing options...
GrenadaV Posted October 29, 2018 Author Share Posted October 29, 2018 Thanks for the response DevBiker, much appreciated. Can't provide temperature, as the PC is not going, just about to rebuild it from scratch. and this issue popped up. I did not think it would be heat as it happens as soon as you switch it on. That is why I thought it may be a cable, whether I am using the wrong one for something, or have plugged one into the wrong slot on the PSU....? Just trying to figure out anything now....:confused::(: Link to comment Share on other sites More sharing options...

GrenadaV Posted October 30, 2018 Author Share Posted October 30, 2018 Hey there, GrenadaV, how are the fans controlled? Are they connected directly to your mobo and controlled with software or BIOS? Hi Corsair Mint, Thanks for getting in touch. They are plugged directly into the mobo, 1 is a cpu fan and the other is a pump fan. It seems the pump fan that is going crazy, instantly when you turn it on. I have taken it apart again to try and see if I went wrong with the power cables and checking the connections against the original PSU. The PC is a HP Omen X Desktop, its large and heavy, but a bit fiddly to work on and although it claims easy access, that is only to 1 main area, I have never had a PC where you have to remove the mobo to get to the PSU. I have just ordered a Obsidian 1000D, and am hoping to transfer my existing mobo into that etc. (sorry i'm rambling a bit now, irrelevant info).

DevBiker Posted October 30, 2018 Share Posted October 30, 2018 Uhh ... First, it's certainly possible that HP has some kind of custom requirements for their PSUs. They've been known to do that. I take back my previous statement - I assumed that you were working with a standard motherboard. You aren't and it may or may not follow the full ATX specification. The HX absolutely does follow the ATX spec. Second, it's entirely possible that the motherboard isn't a standard size. Again ... they've been known to do that. In fairness to HP, all of the PC makers do this. Note: this should highlight the importance of filling out your system details. As for your fans ... if they are connected to the motherboard, that's where you need to start. Link to comment Share on other sites More sharing options...
GrenadaV Posted October 30, 2018 Author Share Posted October 30, 2018 Hi DevBiker, Yes I hear you regarding specs. The mobo is a mATX, so in theory it should be the same specs as any other mATX mobo, but like you say, it has possibly been modified to suit HP. Plus what you mentioned about the PSU possibly having specialised or custom specs to suit HP, this just confirms why I started building my own PC's years ago, and that I will not be buying any PC makers PC's again. This was sold as a fully customisable PC, but now it seems not to be the case. I will throw the original PSU back in and see how that goes, but it means I can't use my new RTX2080 Ti......grrrr I am going back to building my own again, and to start that process I have ordered an Obsidian 1000D, now all I need is a new mobo etc. Thanks for your help kind regards Ross Link to comment Share on other sites More sharing options...
DevBiker Posted October 30, 2018 Share Posted October 30, 2018 Well ... what they mean by "fully customizable" and what you or I mean by "fully customizable" may be two completely different things. Of course, it may be to spec. It's just so hard to tell with anything from the custom PC makers. Link to comment Share on other sites More sharing options...
