TOP-700P7 SEZ (700W) and TOP-750P7 FEZ (750W)

Now I return to the P7 series. This time these are high-wattage models with detachable cables. Perhaps they’ll prove to be better than the rather unsuccessful 500W and 600W models from the same series?

The CPU and mainboard cables are not detachable in the SEZ model and detachable in the FEZ model. I don’t quite grasp the idea, though. Did you ever see a PC without a mainboard?

The manufacturer doesn’t think it necessary to specify what exactly PSU is in the box. The picture on the package shows both the models (the FEZ on the left and the SEZ on the right) while the sticker only indicates the wattage of the PSU.

A lot of space is given to an illustrated description of technologies such as active PFC, quiet operation with automatic fan speed regulation, and a special relay that allows connecting other consumers to the PSU so that they would be shut down together with the PC.

Alas, the other side of the box looks like a practical joke. It turns out Topower has got a lot of “exclusive” technologies but our sample of the PSU has none of them. It doesn’t have active PFC or an additional relay or anything. These are just shown in the pictures for you to know such technologies exist. Theoretically. In other PSUs.

The two PSUs are identical in front view and look alike to the P7 FR models: a mains connector, an On/Off switch, and an 80mm fan. There is no input voltage switch – the PSUs can only work with 220VAC sources (I wonder if the company produces another model for the USA that works only at 110VAC or employs a switch).

Topower TOP-750P7 FEZ

The FEZ model has 11 connectors for detachable cables on the rear panel: for the mainboard, CPU, graphics cards and peripherals. Despite the color coding, you can see that nothing prevents you from plugging a HDD power cable into the 4-pin CPU connector as both have the same shape and size and the position of the keys. So, be careful when installing this PSU into your system.

Topower TOP-700P7 SEZ

The SEZ model has 8 connectors like the above-discussed Silent Green. The top two connectors are marked with a different color and meant for graphics cards. The bottom six connectors are for peripherals and do not differ in size, shape, and the position of the keys.

Topower TOP-700P7 SEZ

The TOP-700P7 SEZ is almost the same as the TOP-700P7 FR on the inside. It’s got the same PCB and circuit design, and is cooled with two “push-pull” fans, too. The only difference is the card with the output connectors.
