ATX Power supply shopping, any tips?

scottiebabe

I think its time to retire my Thermaltake Toughpower 650W ATX power supply.

Using the 80 plus test database seems like a good start

Fingers crossed LTT starts publishing PSU reviews with that test setup, just wow....

    Do not go on the cheap side for this, I've seen to many horrors. And always take a "bigger" power output than you currently need. It will give you a bit of leeway should you change some components and…

    I have observed that ATX supplies parameters have changed sometime in the past - old ones provide most of the power on 3.3V/5V rails, but modern ones on 12V - to the level that 500W modern PSU cannot power…

    Cool stuff but I think he got the color code wrong - white is neutral, not hot, and black is hot in Canada. Such a mistake could have been exciting.

    Wonderful, thanks for the link. Looks like I'm on the right track as currently I fall in the

    As does mine - I'm running a Thermaltake TR2 Bronze 850W which I've replaced the fan on. My machine has a nice electronics burning smell every time I turn it on ... but it still hasn't failed almost a year after this started happening. I suspect the capacitors are drying up in mine ...

    Nevertheless, usually it's the OEM that matters more than the brand on the side. If the budget stretches, Seasonic stuff is usually decent. But other than that, Corsair usually has fairly decent OEMs too, especially for their higher end lines.

    Overall, the 80-plus program seems to have pushed most reputable brands to at least a baseline level of quality, not like the mid-2000's when there were so many dangerous units out there.

    Careful with the badcaps, it's a good way to kill your hard drive. In the PS as on MB.

    Well, I'll get around to replacing it one day. But since I use it rarely, I'll hang on for a little longer.
