Honestly I would avoid tier 3 or worse like the plague. The PSU is the heart of your system and can fry anything it is connected to if it goes bad. PSUs are the last place you want to try and save money because of this. I mean yes you could use a tier 3...I just wouldn't do it myself or recommend any friend or family member to use one. I do get budget dictates all but is it worth risking losing your entire rig? Only you can make that call.
if all you can afford/find/acquire is a tier three unit get a tier three unit. Not everyone is running a mining rig, or overclocking to the moon.
"Some Haswell compatible, some not (maybe unconfirmed).
Still safe to use and stable, just lower quality components. Not really ideal in serious overclocking or super-high load situations, such as a Bitcoin mining rig or a high end gaming system."
Tier 3 is fine for stock parts at stock speeds.
I cannot change the supply chain in your country and I cannot send money to make sure you can get the best but I can and am trying to get you a power supply that will work for you and tier 3 will.
