I change several types of sleeve cables, sleeve extensions and I want to leave my impression with some of them. 5th Place are NZXT Extension First I try this sleeve and it's on last place for me because look and that is extensions and extensions make mess in PC and PSU cables with extensions lose little only little efficiency 4th place for me and I try that little later are Bitfenix Alchemy extension. This cables are better because it's not so nylon shine like NZXT, loop is better, cables anot deform like NZXT sleeve, preaty good sleeve, no wire transparency 3rd place are CORSAIR Single Sleeve Cables for their modular PSU CORSAIR is one of two my favorites HW manufacturer and he first start to make this and raised that on higher level. Many years enthusiast and overclockers, gamers expect from someone to make cables like this, CORSAIR start that like many other things. But... cables are not perfect at all and I see some people are little dissapointed 2nd place are phenomenal MDPC-X, cables are almost perfect, I have over 35m now and I sleeve some of cables with MDPC-C, famous sleeve in all colours. I see almost perfect and later I will explain why... 1st place and that I see with own eyes and immeditely I become fan of sleeve without srinks. EVGA Single Sleeve Cables from NEX1500 Classified PSU. That people realy need to feal and hold in hands. That wires are stronger than any other, keep shape after hard bent, thinner than MDPC-X, easy to remove without chance to later need to fix cables. Almost 20 cables in package and best option for high quality sleeve... extension are close with price. MDPC-X if you know to sleeve cost more, If you don't than you need more to pay for someone to do that. With many brands like Seasonic lose warranty... and AX1200 price with both CORSAIR sleeve or MDPC-X sleeve are over price of NEX1500W. Because of that and 10 years warranty, best look, impossibile to deformate when bent like MDPC-X, no need to fix srinks or afraid if move something, keep thinn shape and no wire transparency, because I have MDPC-X next to this in PC definetely and I see diference 1st place NEX1500 Cables This is only natural position for cables and you can't pack in beg like other cables without strong unnecessary force If you know for some sleeve cables, finished or other give your impression. I saw these types 4 of them I try in own PC.
