If I remember correctly, OCZ is one of the few that has 1-1 cables. That makes it alot easier. I can't remember for your specific PSU, but I remember that alot of OCZ PSU's have the capacitors attached to some wires. Now this is a nightmare to sleeve and most people then to cut them. I for one wouldn't get a PSU that uses these if I want to sleeve as although most people say it doesn't affect coil wine if its taken out, I for one believe Manufacturers always try to cut costs, and if it wasn't necessary, they wouldn't have put them there.
One of the best to sleeve are always the Coolermaster and Silverstone PSUs. They both have 1-1 pins and the pins are much easier to remove than pins on Seasonic or Corsair PSUs. Also, they both have no capacitors on the wires.
Mind you, if you are new to sleeving, it probably best to go with a PSU that is easy to sleeve, but that said, If you already own the PSU then you can make the effort to sleeve it by simply taking your time. Sleeving for me is all about patience as thus far, I take several hours to do one cable, but once done, it just looks amazing. I'm sure some of my cables would Pass Lutro's QC.
Hence, even if you are new, and your willing to invest the right amount of time into sleeving, then your safe. Good tools and Patience is all that is needed(also watch all of Lutro's videos. They're long, but well detailed and worth the time)
