The Pure Power 13 M 1200W is one of the latest additions to be quiet!’s refreshed power supply lineup. From a physical standpoint, it is very well finished, with a compact chassis and a generally high standard of build quality. The included cabling is neatly presented and feels robust, which helps reinforce the overall impression of a well-made unit.
From a technical perspective, performance is strong across the board. Although the box lists 80 Plus Gold and Cybenetics Gold certifications, Cybenetics has in fact awarded this unit a Platinum efficiency rating. When we queried this with be quiet!, they confirmed the Platinum result but explained that the product is marketed as Gold because the review sample may have performed slightly above the average production standard. Our own testing placed the unit close to Platinum efficiency as well, making this a somewhat unusual case of conservative positioning rather than optimistic marketing.
Electrical performance is solid. Ripple suppression, load regulation and overall power delivery all meet a high standard. While it does not displace the very best units on the market in these areas, there are no meaningful weaknesses to report. Cooling is handled by a rifle bearing fan which performs reasonably well, though it is not on the same level as the larger and more capable Pure Wings fan used in the Power Zone 2 1200W we tested previously
Pricing is expected to sit around the £200 mark in the UK, based on an MSRP of roughly $200 or €215 elsewhere. At this price point, the use of Taiwanese Teapo capacitors throughout the unit is more difficult to overlook. While modern Teapo capacitors are not inherently unreliable, and we are not suggesting they pose a durability risk under normal use, their inclusion does feel like a cost-saving measure that sits uncomfortably in a £200-plus power supply. Ideally, this would not be a discussion point at all at this level.
Pros:
- Fully modular.
- Technically capable.
- Well built.
- 10-year warranty.
- Strong load regulation.
- Ripple suppression is good.
Cons:
- Teapo caps in a £200 power supply.
- Fan quality falls short of what I would expect from be quiet!
KitGuru says: The be quiet! Pure Power 13 M 1200W delivers strong performance, good efficiency and a well-built, compact design. It runs quietly at lower loads, offers a long 10-year warranty and performs reliably under testing. While pricing and component choices prevent it from being class-leading, it remains a capable option worth considering.
