OCZ ZX 1250W Power Supply Review

Rating: 9.0.

OCZ have been delivering quality power supplies now for over five years and one of their most historic claims to fame was when they purchased PC Power & Cooling, a company well known in enthusiast circles for their extreme high end designs. OCZ have released a new, high end ZX 1250W power supply which is 80 Plus Gold Certified and a fully modular design.

The new ZX series has three family members, the 850W, 1000W and 1250W models. These are created for demanding enthusiast gamers who need the highest levels of power available. All of them are 80 Plus Gold Certified with single 12+ rails.

As well as 80 Plus Gold certification, OCZ have wanted to focus on lowering noise as much as possible, incorporating an ultra quiet 140mm fan into the design. OCZ are backing up the impressive specifications with their 5 year ‘power swap’ warranty.

    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 🙂

    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.

  • Brooke

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

  • NeD

    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.

  • Davy

    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.

  • Hester

    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.

  • @ 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. 🙂

  • Petee

    Great design, looks nice too

  • Uriel

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

  • Colm

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

  • Paul

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