Summary: The OCZ ZT Series is very well priced and we were surprised to find the 550w model online for as little as $90. As tempting as that is, potential buyers could be even more tempted by the higher capacity units which are only a fraction more expensive. The 650w version for example costs just $10 more, while the 750w version is another $10 again.
Summary: The OCZ ZT 650W is the first power supply we have seen from OCZ’s ZT line as well as being the first power supply we have seen from OEM Great Wall. On top of that, the OCZ ZT 650W is the smallest capacity power supply we have seen from OCZ to date. With this capacity this unit is going to find itself competing against many entry level power supplies where we have seen a number of train wrecks over the years.
Summary: OCZ comes to us with a new "High-Performance" computer power supply that sports 650 watts along with fully modular cable management. OCZ tells us "this power supply remains rock solid and stable" under typical load environments. Will this new OCZ offering come in looking worth its $90 price tag and Bronze efficiency rating?
Summary: As was the case with the ZS series, the ZT features a solid black chassis with decorative stickers on either side. The key difference between the two series is of course the 100% modular cable design, which I personally am a fan of. Modular cables allow for much better cable management by eliminating cables you won't be using rather than having to try and tuck them out of sight behind the motherboard tray.
Summary: The OCZ ZT Series 650 W proved to be a flawless power supply, with high efficiency between 82.1% and 86.8%, voltages closer to their nominal values all the time (3% regulation), very low noise and ripple levels, and a fully modular cabling system. All of that sells at a terrific price of USD 100, making this product a no-brainer if you are looking for the “perfect” power supply with a full modular cabling system.
Summary: Two units that play in the same category along with OCZ ZT 750W are the
, both of which we have reviewed in the past here at TechPowerUp. All three, aforementioned PSUs have almost the same price, provide five years warranty and are 80 PLUS Bronze certified. The biggest advantage of ZT 750W over the two opponents is the fully modular design which will make cable management a breeze.
Pros: Good price/performance ratio, Real 45°C continuous output rating, Fully modular design, Good noise/ripple suppression, Japanese caps in the secondary side, Strong 5VSB rail (4A max), Five year warranty
Cons: Noisy fan at high loads, A little loose voltage regulation overall, No MOV in the transient filtering stage
