Atom_Anti Posted February 10, 2008 Share Posted February 10, 2008 I`ve just bought a visiontek x1950pro agp, therefore I have to buy new power supply too. I would like to buy a Corsair 450VX or 550VX power supply, which will be perfect to my future computer too. However now I would like use it with an old Pentium 4 system, and I`am not sure these modern Power supplys can work with it. So, is the 550VX with +3.3V@30A,+5V@20A or the 450VX with +3.3V@20A,+5V@20A output can be enough to my system? Thank you! Link to comment Share on other sites More sharing options...
EliteKiller Posted February 11, 2008 Share Posted February 11, 2008 Your board supports ATX 2.01 & up psu's, so either VX psu will provide more than enough power for your current rig. If you can afford the VX550 it will give you additional headroom for future expansion. The VX550 is only $57.99 AR & GC Link to comment Share on other sites More sharing options...

Atom_Anti Posted March 12, 2008 Author Share Posted March 12, 2008 I need help, I bought this nice psu, but the computer not working with it. So I connected the 24pin psu connector with the 20pin motherboard connector, and the 8pin with the 4 pin motherboard connector. I think these connectors fit well. After this installation I`ve turned on the power supply, and the green light on the motherboard is working, but when I press the power button on the computer it is won`t start. The cpu fan is make a sudden movement, but the motherboard is turning off. The green light on the motherboard still working, but keep pressing the power button on the computer, don`t make anyting. If I install back the old power supply the computer is working. What is the problem? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted March 12, 2008 Corsair Employees Share Posted March 12, 2008 Try this: http://www.asktheramguy.com/v3/showthread.php?t=63991 If the PSU fan spins up and stays on, then there may be an issue with the motherboard. Make sure that the motherboard supports ATX 12v 2.0, and if possible, I would test the PSU in a different system to see if you have the same issues.

Atom_Anti Posted March 13, 2008 Author Share Posted March 13, 2008 Ok I made the Brief PSU Functionality Test, and the psu fan spin right up. The psu is not perfect silent, it is make some buzzing noise, but I would not care if the computer would start. My old psu is atx 2.03 version, so I guess the Abit IS7-E support the atx 12V 2.0. In hungarian forum somebody said me I need for the following adapter:http://pcgear.hu/components/com_virtuemart/shop_image/product/8bef0484e0ed058d2f35b2e60247dc50.jpg This adapter transfer the 8pin to 4pin. I am not sure about this because the 8pin already fit into the 4 pin connector, and I think it is cannot make any difference to me. Isn`t it? I would try this psu in another computer, but I am leaving in hungary in a village, so nobody has modern computer. I really would like start my computer because I just bought a radeon x1950 pro, and it is need lot of power. Do you have any idea? Should I change anything on the FPIO1 (Front Panel switches and indicators connection)? Thank you! Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted March 13, 2008 Corsair Employees Share Posted March 13, 2008 You do not need the adapter. There are most likely 2 possibilities. One is that the PSU is tripping the "Over Current Protection" or "Over Voltage Protection" due to an out of spec signal from the motherboard (not all PSUs have these protection circuits). The second possibility is that there may be a bad component in the PSU. Before having the PSU replaced, if possible, you may want to test it in a known working system. If it gives you the same issues, we would definitely want to have it replaced, however if there are no problems in another system, you may want to RMA the board. If you decide to try to get it replaced, then please use the On Line RMA Request Form and we will be happy to replace it. Be sure to check the box that says “I've already spoken to Technical Support and/or RAM Guy.” Link to comment Share on other sites More sharing options...
Atom_Anti Posted March 13, 2008 Author Share Posted March 13, 2008 Ok I`ll try to find an another computer and try the psu there too, just for make sure if the psu would wrong. Today I also discovered a problem possiblity too. To me look like that 8pin rail would go into the 4pin connector with the another side too. But I am not able to put there, because a condenzator of the motherboard don not leave me enough room to put to there. Here you can check it out what I am talking:http://www.oc.com.tw/article/0307/imgs/ddris7e-02.jpg Near the 4 pin connector there is an gold color condenzator, and the 8pin connector cannot go all the way to down, because that is block the way. What do you think? I hope we can figure out this problem without using RMA. Thank you your help! . Link to comment Share on other sites More sharing options...
smithkt Posted March 13, 2008 Share Posted March 13, 2008 If you look closely at the 8 pin connector, you will see that it can be split into two 4 pin connectors. Separate the two halves and plug only the 4 pin connector to the motherboard. This will solve your clearance problem. Only one half of the connector will fit correctly. Make sure you use the correct half. Link to comment Share on other sites More sharing options...
Atom_Anti Posted March 17, 2008 Author Share Posted March 17, 2008 I think you find the problem! When I seperate the connector into two halves, after the computer boot up, and work fine. The psu also very smooth and give lot of power. Corsair make great power supplys and great costumer service too! Thank you! Link to comment Share on other sites More sharing options...
