Maximum HDD/SSD count is 3 per, but most have only 1. Thus, my PCs' power requirements are relatively modest. Maximum CPU core count per PC is 6. Max CPU TDP is 125W, in one only (running on a 430W). All the rest are 85W TDP or less. Nearly all those I bought before 80+ eventually required recapping within 5 years of age, or warranty replacement. The EA500 was returned because it always shut the PC down during UPS transition from 120V to battery. 2 of the other Earthwatts also needed recapping. AFAICT, I've never overloaded a PS that wasn't itself failing. Since dual 12V rails became a thing, I've always avoided such models - KISS. I buy on sale rather than immediate need. So, my cost has typically been in the $20-$30 discount (or rebate) off regular price range. -- Evolution as taught in public schools is, like religion, based on faith, not based on science.

I generally find: Seasonic EVGA Corsair to make reliable power supplies. I can't speak to AC supply problems, because I always put any computer I care about behind a UPS. The Seasonic S12III series has several units in the $50-75 range according to required power. -dsr-

I've used a number of cheap Chinese 300-400W power supplies in the $20 range and they all worked for years without any issues. Regards,
Re: ATX power on
Does anybody how to make an ATX motherboard boot without having to press the 'power' button everytime? That is, I want an standard AT behaviour: if there's power in the line, then I want the machine running without having to press anything. There was a long discussion of this on slashdot.org last week; look in their archives. The solution is to electrically connect (certain) two of the wires in the bundle that plugs into the motheboard, or else to connect some of the wires leading to the power 'switch'. The deatails are over there. Carl

That should translate to (if these two pins are connected, the power supply is supposed to be on, until the drop and then go on again.) I believe that's incorrect. The power switch is a push button switch; one pulse on those pins will switch the thing on, another will switch it off (or suspend mode, as configured in the BIOS). It might be that holding the switch in (ie connecting the two pins permanently) does the trick though. Hamish -- Hamish Moffatt VK3SB (ex-VK3TYD). CCs of replies from mailing lists are welcome.

This is more than likely a function of the BIOS of your motherboard. Look through your BIOS and see if it supports this functionality. If it doesn't you're probably out of luck. Gary
Re: ATX power on

That should translate to (if these two pins are connected, the power supply is supposed to be on, until the drop and then go on again.) Your BIOS manual might tell the tale, some careful experimentation might as well. Insert standard caveats here.
