Isokolon :
With haswell (4th Generation Intel i-CPUs) Intel introduced some special low power states.
Now some especially older designs don't support those power states and according to.their features detect there's something wrong when this little.power is consumed and shut down.
More modern PSU design factor that in and are compatible with it.
All of those I listed in the first paragraph and most of the PSUs in the second do support them though.
I myself use a XFX TS Gold and am rather satisfied although I'd invest in a semi-passive cooled unit that is (semi/)modular today (but I hate hearing any noise from my computer and f*** up cable management too easy)
Units that for example aren't compatible with it are fore example the XFX TS Bronze, Core, Pro - Seasonic S12II/M12II - Antec HCG off the quality supplies
Generally it shouldn't be a problem as long as your HDD is put to sleep as well. Otherwise an HDD that was built for 24/7 use would be necessary.
Thanks.
I cannibalized my old computer and moved my Western Digital Caviar Black HDD to my new rig while installing a small SSD to house the operating system and a few utility programs. That WD Black was purchased in 2008 and is still going strong! I'll probably buy a larger WD Black for backups and buy a much larger SSD in the near future for games, media, and everyday use (M.2).
I'm going to replace my power supply first, then worry about a new SSD. I've already added some fans and I might eventually buy a new cpu cooler (Noctua NH-D15S) to replace my Cooler Master 212 Hyper LED but I'm not sure if it's really warranted?
I'm already overclocked @4.2GHz (seems like I got a middle of the road chip) but can't seem to get 4.3GHz stable under Prime95 (older versions). I think I'll tinker around some more in the next few weeks. I was kind of surprised my 6600K didn't hit the allegedly easy to obtain 4.6GHz with relatively low voltage values? The best I could do stable has been 4.2GHz (Adaptive Offset+ with a Vcore of 1.27 and the offset @ 0.040mv).
You never gave me a clear answer on what you thought about 24/7 computer use?
