yeah I use them on all mine and never really had any problem with them, i mean the molex sata connectors are always crap, but you will probably end up with extras of those anyways since you will use some direct molex from your PSU
they are the ones I use, they are Ver. 6 boards (most people recommend over v.4… ive heard recommended v.4, 5, but i bet they just have not used V.6 yet 
V.6 must be better than 4 or 5 anyways 
they come with 50cm USB cable, but you can also get 30cm and maybe longer on custom order
there is also a version with a voltage regulator, they cost slightly more but I dont think its necessary
you can send me ETH for them, if you are sure you want them i will check the prices for you and shipping.
2 ways for shipping, slow airmail or fast EMS express mail service. … I guess if you are in a rush to get them then EMS is the best way.
Probably better get an extra 1 or 2 just incase also, since you need to pay shipping anyways,
