I've bought a Tagan 480W for my new amd 64 939 comp. When I connect the PSU with the mobo and swich the PSU to ON, everything in the room gets dark, and the house-fuses blow up. I don't know what to do... (I've used up about 4 10amp fuses atm) I've got: MSI NEO2 Platinum-54G AMD 64 3200+ 939 Kingston 512*2 PC3200 Club3d Radeon 9800PRO Thanks in advance! /Anton

10A fuses? at what voltage. I don't know where you are located, however 10 amp is way too low for power curcuits. Room gets dark? I think you need an electrician. It is unlikely that your power supply is overloading household power (Not without other signs such as arcing and smoke). It is however possible that you are adding load to an already stressed curcuit. Try turning off other appliances.

I'm located in Sweden with 230V. We usually can supply 10 computers with monitors, with one 10amp fuse. We did try to turn off the lights and stuff though and see if it was the load, but it didn't help. The room gets dark because the fuse is blown and I have to replace it before I can have the lights back on.(you know the fusebox with all the different circuits for kitchen electricity, living room, and so forth..)

Sorry Dreamfluid, there is a matter of different international standards comming into play here. I am in Australia and our wiring convention is more like 2 power points, 1 lighting, 1 stove and 1 Hot water. Try upping the fuse to around 15 amp. Other than that I can't help.

It is possible that your PSU has a short but that probbably would blow something in your PC. Try a different PSU just in case... Try power from a different outlet. That may be the problem but not really that likely. I also live in Australia so I cant offer much more help on other things. But 10 amp does sound a bit low. After all you can get PSU's that have over 18A on their 12V line. Mattwizz3 : ) AMD K-7 600MHz & Asus K7v 256Mb SDRAM 80Gb WDC, 8Mb Buffer 128Mb ASUS Radeon A9550 Cyber Drive CD-RW DVD Combo

If a 10amp fuse blows then you have an internal problem with the power supply or the mains cable - don't try repairing it, get it replaced. Bit of explanation: 'Ohms law - power == voltage x current' so at mains 240v voltage (I'm in the UK), you theoretically don't need bigger than a 2 amp fuse (current = power / voltage so 480w/240v = 2amps), but this would be impractical, so 10 amps is more than enough to allow for temporary surges. Within the power supply, because you've dropped the voltage to 12v, maximum theoretical is 480/12 = 40amps (this ignores other voltages of course). If your power supply is trying to draw more than 10amps then this means at mains (230)voltage, the power it's trying to pull is 230x10 = 2.4kiloWatts!. Definitely a fault - replace cable/PSU. "I know that I'm mad - I've always been mad..."

10amp @220v is the same as 20amp @110v. I wouldn't recommend increasing the ampicity of the fuse. Find out what the problem is. Is the outlet one that has been in use all along or usually not used. Check the individual outlet. You did set the power supply for the higher voltage, didn't you?
