InWin P125 1250 Watt PSU

InWin also sent along one of their new P Series power supplies. This line starts at 650 watts and goes all the way up to 1250 watts. We received the InWin P125, which is the strongest P series PSU at 1250 watts, and it is 80 Plus Gold certified. It ships in a full-color box with an image of the power supply on front and all the usual details on the back.


InWin includes some thick and sturdy zip ties, a set of screws, and the usual power cable with the PSU. Instead of a manual, a business card with a QR code takes you to the digital copy. As the P125 is a fully modular unit, none of the cables are attached. These are of the flexible, flat variant so popular with brands lately.


Even though the P125 can deliver 1250 watts, it is rather compact at just 160 mm long. It employs a 135 mm FDB fan that only turns on at loads above 20%, making the P125 semi-passive.


All the plugs for the cables are flush with the housing. As such, the P125 will truly fit into cases that have a 160 mm limit, which happens to exactly be what the InWin Explorer is officially able to handle. The unit's rating can be found on a sticker on the large, solid side, while both smaller panels come with the black and yellow device-specific numbers, so what is powering the system in front of them should be obvious to any onlooker.
