# be quiet! Pure Power 13 M 750W (ATX 3.1)

**Power Supply** — DealCoconut researched pick in The Value PC Build
Canonical page: https://www.dealcoconut.com/p/psu.html

- Current price: $89.90 (MSRP $109.99)
- Known low: $89.90 (current)
- Buy timing: **Good time to buy** — $89.90 is below the outgoing model's street price for a newer platform.
- Reliability: **5/5** — The PSU is where reliability IS the product: full OVP/OCP/OTP protection suite, 105°C Japanese capacitors, 10-year warranty. A failing cheap PSU can take the whole build with it — this is the one slot where we never consider the floor.

**Why this pick:** 750W ATX 3.1 is this build's sweet spot with comfortable headroom, and the refreshed Pure Power line currently sells below the outgoing model.

**What it beat:** 850W+ units — $30–50 for headroom this build can't use. And no-name 750W units that skimp on protections.

**Cheaper alternative:** Corsair RM750e trades blows at the same price — buy whichever is cheaper the day you order.

## Common questions
- Is 750W enough headroom for upgrades? — Handles anything up to an RX 9070 XT / RTX 5080-class card; you'd only outgrow it going flagship.
- 12VHPWR melting worries? — This build's GPU uses standard 8-pin connectors; the included 12VHPWR cable meets the revised ATX 3.1 spec anyway.
