Question about XION PSU XION|XON-800R14N 800W RT

1 Answer

Whining sound with xion 800 watt power supply.

I replaced my blown 600w xion with an 800 Watt version. When I start the PC I get a high pitch whining noise. any ideas what that is? do you know where I can find an installation schematic. The new supply has nicely loomed wires. I doubt the fan is rubbing a wire.. any help on installing would be great if you could recomend a source for instruction. Thanks,

There is a fan insine the power supply, and also a fan on the CPU. Occasionally there is also a fan on the chassis of the computer itself.

Turn on the computer, take the case off, and listen to identify the source of the noise. If it's inside the PSU, return it and get a new one.

Power supply


Any 450 Watt SMPS power supply is ok. Zebronic or Mercury retails around Rs.450 to 500. No need of costlier power supply like Corsair etc.

What is the price of a power supply which is CAC-T05-UW?


Here is a list of power supply list from 39.00 dollars to 79.00 bucks the lower priced have lower wattage so depending what all your running you may want to run a better power supply however it depends on how long you want to keep the computer it's the older power supply system but if your not going to upgrade anytime soon then the choice is up to you I run a 600 watt which runs all the high tech stuff I have. like 7 DVD players a floppy drive and the mother board and a 2.3 gig amd chip and cobalt freeze fan. hope this helps and good Luck thanks for using fix-ya. one last thing most power supply's are identical in size and will fit in the power supply slot. Thanks for using fix-ya

I have a power supply that is turning itself off immediately after switching it on it is a new motherboard as well Any ideas why ?


I think either the MB or the CPU is with problems.

Try (2 after 1 works, 3 after 2 works...):
1) only PSU+MB+CPU and Fan - works? beeps like crazy?
2) add memory - works? single beep?
3) add/connect video - any image?

All other connectors off (disks, etc) only PSU, fan and case buttons.


If you don't get past 1), go back to the store and have it tested/returned there.

Loud buzzin sound on start up


If the POST screen is coming up, showing the the correct amount of memory in the system, and then telling your hard disk failure or something similar, your hard drive has failed. Put a new hard drive in the system, reload your operating system and all drivers, and attempt to use the old hard drive as a second drive long enough to get any files you need from it.

Power on Problem!!


Did you plug the cables for the front devices and buttons into the motherboard at the right locations? Are the polarities correct on for your cables?
