Sleeved Cables compatibilty with AX1200i

[EdHart]

I need to add 1x 24-pin ATX and 2x 8-pin (4+4) EPS12V cable to my new build. By looking cable compatibility chart it seems that AX1200i is compatible with Type 3 cables. However, "Professional Individually sleeved DC Cable Kit, Type 3 (Generation 2), doesn't come with 24-pin ATX (weird!) but "Premium Individually Sleeved PSU Cables Pro Kit Type 4 Gen 4" comes with 24-pin ATX extension, now questions;

1. Will "Premium Individually Sleeved PSU Cables Pro Kit Type 4 Gen 4" satisfy my needs with AX1200i? According to chart, it seems 8-pin EPS12V is compatible but not sure about 24-pin ATX.

2. Would any Sleeved Extension Cable kit or any 24-pin ATX extension cable (different vendors) work with AX1200i? I already have a complete set of sleeved extension cables.

3. What "Generation" means ie: Gen 4? Nothing is mentioned in compatibility chart. For instance, does any Gen 2, 3 or 4 (Type 3) cable kit works with AX1200i?

4. Why so confusing?!

PS: Shipping cost for a $4 cable is $10 (CA, US) in your website for god sake!!!! Your shipping costs are really deal breaker for people who actually want to purchase directly from your website! I don't think a cable costs you more than $3 to ship nationwide!
