1. TT makes rubbish PSU's always have most likely always will
2. Antec costs allot but the performance isn't proportional, middle of the road at best.
3. Seasonic make excellent PSUs amongst the best
4. Nothing wrong with Aopen esp the 700Watt model, great PSU that.
5. Just in case you didn't get it TT makes rubbish PSUs. (All of them...)
6. Coolermaster isn't bad but even their 1KW unit struggles with excessive loads form time to time but could be worth it
7. Silverstone Strider series is the best you can get locally, no contest from anything else.
8. Two PSU's for 24/7 operation can be a bit dicey and even when you have two PSU's they still need to be very good quality. That is you're going to spend R800 or so or R1,600 for two. At that price maybe a single SilverStone Strider 850Watt unit would be better. RRP ~R2,100~ Yes it's R500 extra but you get a 70A 12V Rail (Split in two only. 35A each!

)
9. Not just advocating for Silverstone for kicks, it really does put out.
