Two units that play in the same category along with OCZ ZT 750W are the
Corsair TX 750M and the
Inwin Commander II 750W, 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. Regarding ripple suppression the Inwin unit features the best with the other two being a little behind but still at a very good level. In the efficiency area all score about the same, with the OCZ ZT 750W showing a little better efficiency at very low loads. The biggest drawbacks of the ZT 750W lie in the increased fan noise at high loads/ambient and at the looser voltage regulation at +12V. However I should note here that voltage regulation at +12V is still within 3%.
To sum up, I think that the OCZ ZT 750W stands very well against the competition in its specific price category. Its main setback is the noisy fan at higher loads but the fully modular design is a significant usability advantage over its competitors and along with the good price/performance ratio it is a good deal for someone who wants a reliable, fully modular PSU with long warranty. So if you don't mind the increased fan noise, at least at higher loads and want the easiest possible cable management then ZT 750W is a fairly good choice which is definitely worth the money it costs.
