OCZ ZX 1250W Power Supply Review

The OCZ ZX 1250W power supply arrives in a stylish box with a quick list of specifications and a high resolution picture on the front.

Inside, the power supply is shrink wrapped (no cloth bag unfortunately) and contained between two soft heavy duty pieces of foam. There is a large box to the right which contains all the accessories.

Inside the accessory box is a pouch with all the modular cables. A user manual, an 80 Plus Gold ‘certificate' and another box containing power cables, velco cable ties and mounting screws. It really is a comprehensive package and one indicative of a high end flagship product. The cable pouch is packed with cables and is actually difficult to repopulate fully once some of them are removed.

OCZ even supply both a UK and European power cable in this box, which is unusual.

There are no shortage of cables, although as this is a model catering to the elite, high end user base, OCZ can't afford to make any compromises.

Modular Connectors

  • 20+4 pin ATX
  • Dual 4+4 pin CPU
  • 6 x PCIe 6+2 pin
  • 12 x SATA
  • 9 x Molex
  • 1 x Floppy

It is worth pointing out that not all of the SATA and Molex cables can be connected to the unit simultaneously. The PCIe, ATX and EPS are thicker 16 AWG cables while the others are 18 AWG. All of the cables are all fully sleeved, so bonus points for a thoroughly impressive set of cabling. They are all initially 560mm in length with + 150mm for each of the Molex or SATA connectors after that.

  1. Well thats a nice supply, amazing how the prices change for the Uk though. $240 is a good price, but it will probably translate to £240 here. UK sucks 🙂

  2. I like the cabling, thats quality. Tons of it too.

    I had a bad time with the gamexstream range years ago and it put me off them, but I think they had a bit of a problem with that range, and nothing else.

  3. Can you add some real world tests? like does it power 3 HD6990s? that kinda thing ? 🙂

  4. Good to see OCZ doing other products, rather than this constant focus on just SSD’s. They used to make some damn fine memory, those were the days. I prefered their memory to corsairs.

  5. This range looks great, hey Zardon any ideas on the pricing of the lower models? an 850W in this range would really be ideal for me.

  6. Looks like a great supply, I agree with the other dude in here, 850W sounds like a good size, probably be 50-60 less too.

  7. @ Brooke. It will power any combination you need, no problem. Not sure anyone would want to power three HD6990’s mind you as you can’t actually use three in Crossfire. 🙂

  8. Great design, looks nice too

  9. What are the benefits of a pure modular design? Doesnt a system always need the atx connector anyway?

  10. Nice step up for ocz, their psus have been consistently average for years.

  11. Cant find it stocked anywhere. When is it released.? Cant see it being under £200
