Can someone recommend a good PSU by any chance?
I've recently moved to Taiwan, and I think this is the web site they use a lot for purchasing things online. It lists a lot of PSU on there, I have the 700w-1000w range selected. Can anyone see if they see any good psu from that site by any chance? ^_^ thanks in advance

Also, I've had 2-3 psu died in the past 7 years or so, should I look into getting a UPS or AVR ? I have no clue when it comes to these surge protection units. What's the difference between UPS and AVR? and which is actually preferred for protecting your computer and power supply? They seem to vary greatly in prices.

    for power supplies get anything on this list on the tier 1 or tier 2 lists and you will be good.

    well known brands make some crap power supplies, this list is made of the creap of the crop models from each manufacturer/brand.

    you want to get a UPS. with a UPS the computer is always running from the battery, all the time. when the power cuts out, the battery will let you shutdown safely. when the power spikes it will go into the battery not your PC.
    make sure you get one with a big enough battery for your needs, that will depend on how long you want it to run x the hardware you need to run. get one with a pure sine wave inverter these are more complex but more reliable.
