What sort of games do you usually find fun to play for relaxation? Most people think all games are meant to unwind, especially since few people do it for a living. However, there are many games I play that are not relaxing at all. For example, playing League of Legends or VALORANT is often not relaxing. I am often playing for-fun modes like ARAM in League, but it can get fiery at times. Worse yet, I am not good with strategic FPS games, as their quick deaths often leave me shocked more than anything. I would only ever play these games because I can play them with others. Even party games from franchises like Overcooked or Super Mario Party can get quite competitive. Single player games too can require a bit of brain power or forethought. The only games I have found to be stress-free are Stardew Valley and Animal Crossing, which is not too surprising. Between its open world and little instruction in the game, you are free to approach the game in any direction. Better yet, if you cannot do something, you can just go to sleep in the game and accomplish these tasks the next day. On the other hand, I am not sure how many people correlate relaxation and power supplies. For one, the PSU is a vital and crucial part of your computer, so you do not want to relax too much when shopping for one. However, I think a power supply should leave you feeling relaxed because you know it is capable to drive your system. In fact, you do not want it to be flashy or provide drama, as reliability is much more appreciated here. Today, we have the be quiet! Pure Power 13 M 1000W, which is yet another PSU in be quiet!'s Pure Power lineup. How will this latest option compare? Will it provide us with a drama-free and relaxing experience? Let us read on to find out!
Today's unit of the be quiet! Pure Power 13 M 1000W arrived from a Newegg distribution center in Ontario, California. This has been how we have received most of our recent be quiet! products, so this is no surprise. This brown corrugated cardboard box traveled with UPS and their Standard ground service to our APH Networks location here in Calgary, Alberta. It arrived in excellent condition with no bumps or bruises to be concerned about.
The retail container of the be quiet! Pure Power 13 M 1000W looks like the preceding power supply units in the Pure Power lineup, including the recent Pure Power 12 M and Pure Power 12. This starts with an all-black box. The be quiet! logo is on the top right corner, while the certifications of 80 Plus Gold and Cybenetics Gold are on the top left. In the middle, there is a scaled down image of the power supply, which looks like the Pure Power 12 units. The product name is located underneath all of this, including the power output of 1000W. The box is quite minimal, but there are a few specifications and features on the back side of the retail container.
Before we proceed, I have grabbed the specifications from the manufacturer's website for your viewing pleasure:

The be quiet! Pure Power 13 M 1000W's retail package can be opened by releasing the flap along the bottom. Once open, you can find the bundle of modular cables wrapped in a twist tie. The power supply is situated in a bubble wrap bag and protected with a cardboard cover on the top. Otherwise, you will also get four screws for mounting your power supply, an AC power cable, some zip ties for cable management, and a product manual. This is the exact same set of accessories we have seen from their Pure Power 12 M 1000W.
