In Win Classic Series 750W Power Supply Review

It has been years since we have reviewed a computer power supply from In Win. You might remember the In Win name from being a prolific case supplier back in the early enthusiast days of the 1990's. How does In Win stack up in 2016 with its Classic series PSU that has a very sleek look to it and nice feature set?


In Win Development Inc. is one of the larger chassis manufacturers in the market and, like some of those other manufacturers, they also happen to maintain their own branded line of power supplies. What sets In Win apart from other chassis manufacturers that build power supplies is that In Win predates many of the current big name chassis manufacturers in the DIY market as it was founded in 1985. (The original BlowHole case built by HardOCP in 1998 happened to be an In Win chassis.) Beyond that, In Win began to develop its own power supplies in 2000 becoming a true OEM and retail power supply company. However, not all of In Win branded power supplies over the years have been produced by In Win as they have also used other OEM's such as Andyson and CWT. Today though, we are looking at the In Win Classic Series C 750W (C750) which is one of those products that In Win builds in house.

The Return of a Classic Brand

The In Win C 750W is only the third power supply we have seen from In Win over the years and it has been some time since we have seen an In Win branded unit. Today though, we get a unit that is not only branded by In Win but built by In Win as they are also a PSU OEM. This certainly makes for an interesting review not only because there are many 750W units on the market, but because we have not seen this platform before from anyone. Hopefully, this unit will build upon the good, though not amazing, foundation we have from previous In Win units and give us something to talk about. Before moving on though, let's see what In Win has to say about this unit today:

Available now in 750W and 900W options, with extreme wattage models following soon, the new Classic Series of PC power supplies is 100 percent designed and constructed by In Win in-house.
