The Pure Power 13 M 650W distinguishes itself with Platinum-level efficiency despite Gold certification, exceptional voltage regulation, and outstanding ripple suppression. The semi-passive cooling and FSP's mature platform deliver excellent thermal management and acoustics under most operating conditions. Elite capacitors raise minor concerns about longevity, though the 10-year warranty provides reassurance. The price sits high for Gold certification but represents solid value when compared against Platinum-tier competitors.

In the Box
The Pure Power 13 M 650W arrives in sturdy cardboard packaging with an all-black aesthetic. A picture of the unit dominates the front panel, while specifications occupy the rear. Internal protection consists of a nylon pouch and basic paper inserts that secure the PSU during shipping. This packaging approach prioritizes function over presentation.
The bundle includes only essential items. Mounting screws and an AC power cable constitute the entirety of included accessories. A few cable ties assist with management. A basic printed manual provides necessary installation guidance without excessive documentation.
The fully modular cable configuration allows complete customization of connected cables, including the 24-pin ATX connector. All cables feature uniform black coloring across connectors and wires. Most cables utilize flat ribbon-style construction for simplified routing, though the 24-pin ATX and 12V-2x6 cables feature black nylon sleeving. The 12V-2x6 connector carries a 450W rating, appropriate for the unit's capacity. An unusual CPU power configuration provides one 4+4 pin EPS connector alongside a single 4-pin EPS connector, creating an asymmetric arrangement rarely seen in modern designs.
