PSU compatibility

[NecroFlex]

Ok so this is something that i wasn't really paying attention at all, so i had a normal LC Power PSU, 550W, not too old, but not new either. So i decided to upgrade my dad's work PC (atm he's got a Q8200, got him a G3240 with an asrock h97m pro4) so i connected everything up normally and tried to start it up...nothing, tried again, reset CMOS etc. nope it was basically dead...so i thought the PSU was dead and so i tested it in an old 487 mobo i have lying around. Worked at first try, so i didn't really know what the issue was. Then i remembered seeing on some PSUs the ''Haswell compatible''. I always thought those were there just for the lolz, not really meaning anything, but from now i see that there's something with the compatibility, can anyone explain this? Thanks

 

EDIT: damn forgot to say i put another PSU in the dad's machine and it booted up fine first try.

Haswell had a series of improvements, that includes power. Certain Haswell chips have an ultra-low power mode that uses so little power that some cheaper power supplies think that the computer is off. Make sure you're using a reputable power supply brand, like Corsair, Seasonic or Cooler Master, as these will almost always have compatibility from the very start and build quality with Haswell chips. (I have never heard of LC Power...)

"Haswell compatible" PSUs are ones that can dish out a low enough amount of electricity along the minor rails, thus your PSU is probably not Haswell compatible as it's made by LC Power and belong in the garbage.

 

If you want it to sleep properly then disable the deeper sleep states in the BIOS and you'll have no problems there, however I'd get a new PSU.

Lol, i had it lying around and tried it, for what he needs it would have been fine (work, using teamviewer and internet browsing), yes they are a low end company, but for something like my dad needs, they are ok enough, i myself never had issues with them.

Just because you've used them yourself doesn't make them good though. Issues can pop up from a variety of different use cases. I had a Lenovo prebuilt that had the PSU die about 6 years from when it was bought and this PC was only ever used for web browsing.
