The unit's continuous power output is rated only up to 40°C and on top of that it does not feature OTP (Over Temperature Protection). This is something that doesn't look so good.
Its dimensions are the normal ones and the same goes for its weight. Finally with a $100 price tag it will meet hard competition (like Corsair TX750 V2) but with the mail in rebates (in the U.S.) you can find it for as low as $74.99 and with this price it's a really good deal for a branded 750W unit.

|Total Max. Power||750W|
There is only one +12V rail whose max power indicates that DC-DC converters are absent from this unit, for the minor rails generation. The max combined power of the minor rails is more than sufficient for a contemporary system and 5VSB are strong enough with 3A max power.

The 24 pin ATX cable is a little short, we would like to see additional 100 mm here. Strangely enough the EPS cable is quite long at 670 mm.
There are four PCIe connectors (two 6+2 pin and two 6 pin) with each one attached in a different length from the remaining cable. We don't recall ever seeing something similar! Also as you will notice from the table above there are no FDD connectors in this PSU. Finally one company decided to get rid of this scarcely used connector. The main problem we spotted in the cables of ZS 750W is the distance among the peripheral and the SATA connectors which is too short, only 85 mm and we also did not like the fact that the wires among these connectors are not sleeved.
Finally, all connectors use 18 AWG wires, the minimum size gauge that ATX spec requires.
Since this PSU features a single +12V rail we do not have anything to comment about its power distribution.
