Solve : fuse blowing? |
|
Answer» have a msi kt3 ultra 2 m/b 400watt PSU ...main fuse 3 amp blows now and again... Where is this main fuse located?normal kettle type plug to psu from main powerTransformers have a high inrush current and are often fitted with special slow blowing fuses so make sure you are replacing them with the correct type & size. 3 amps sounds a TAD low for a 400 watt power supply. Reading through my power supply book, it says the running current would be about 10 amps at 115 volts. I'm assuming this fuse is on the primary side (input) of the transformer.have replaced with 5amp fuse hopefully this should cure problem other computer running on 3 amp no problems using a q-tech 400watt psu in both computersIt may be worth a google search to get the correct fuse specifications. :-[have sinced contacted q-tec and their advice is change the lead and use another power outlet. poss loose wires on reflection after three e-mails they still did not understand the question. the kettle lead has been cahnged and another power socket used and it still blew i suspect psu feedback as i am using the anti surge device from first blowout. and she is using mine in another socket. so still confused.Hi, This is not really an area of specialty for me but... You say you have an 'anti surge' device but is it a $5.99 special or an actual, performance guaranteed, surge protector? With the first, if you have a surge it blows out a circuit in the power bar and all you have is a 6 place extension cord. I usually use a UPS on any computer, helps with black outs, brown outs and surges. Good LUCK, jimcheers JIM its a proper device in old uk don't suffer many blackout/brownouts anyhow its the wifes computer! she know to back up frequently now.. cheers anyhow (it cost £22 appx 40 us$) cheers for helpFew power problems there? I may move Okay, trial one didn't work, how about this. I did a little searching and found a site with a problem similar to yours listed. http://www.techspot.com/vb/archive/index/t-5450.html May help a little. Also, looking over the QTechnology website I found a disclaimer regarding others selling PSU's as QTec. You probably already know this but just in case, Quote PLEASE NOTE - It has come to our attention that another company called "Q-Tec" has recently entered the market and is causing confusion by offering low cost PSUs in competition with QTechnology. Please be certain that neither QTechnology nor Quiet PC have any connection whatsoever with Q-Tec. We know several instances of customer being disappointed with the quality and noise level of Q-Tec PSUs only to find out later that the product they had bought was not made by QTechnology. If you are not buying directly from Quiet PC, please make sure you know what you are buying, and if the price seems too good to be true, it probably is! To add further to the confusion, we now find that there is a third company calling themselves Qtech who have started offering pre-built PCs. Again, our position is that we have no association with them. Ve try, ve try, sometymps ve fail but ve try. jim cheers for that changed wifes over to spare 300watt psu seems okay at moment |
