After Hardwarecooking’s gold medal, a second opinion: Pause Hardware hooked the MRR-1300AP up to a Ryzen 9 7900 and a Radeon RX 6900 XT, power meter and sound meter in hand. Verdict: “Recommended”.
Two benches, two methods
In September, Hardwarecooking recorded the MRR-1300AP's voltages under an RTX 4090 and awarded it gold. Pause Hardware tackles it from the other end: it doesn't stop at voltages, it measures what the PC draws at the wall and how much noise the power supply makes.
Same product, different build: an AMD platform — Ryzen 9 7900, Radeon RX 6900 XT, B650E motherboard. Two complementary takes, reaching the same conclusion on the essentials.
- overall score, “Recommended” badge
- 8,8/10

The protocol, step by step
No electronic load: a real gaming build, and instruments.
Building a real system
Ryzen 9 7900, 32 GB of DDR5-6000, Radeon RX 6900 XT, NVMe SSD: the MRR-1300AP powers it all.
Ten minutes at idle
First reading: the PC draws 85 W at the wall, and the power supply delivers 90%.
Twenty minutes under AIDA64
Processor and graphics card loaded together: 508 W at the wall, 93% efficiency.
Twenty minutes of gaming
Rise of the Tomb Raider: 491 W at the wall, 92% efficiency, the 12 V rail steady between 12.24 and 12.27 V.
Listening
Sound level meter at 30 cm, every other fan switched off: 38.6 dB(A).
What the review concludes
Very stable
0.25 % deviation on the 12 V, less than 0.5 % on the 5 V. The reviewer notes small oscillations on his 12 V curve, without consequence, and rates voltage stability as very good.
Discreet, without switching off
Drowned out by the PC's other fans, the 140 mm goes unnoticed. His only regret: the power supply, by his observations, does not stop its fan at low load — it could have been quieter still.
Among the best
€187.99 for 1,300 W Platinum, a ten-year warranty, a 12VHPWR connector for recent cards and controllable ARGB lighting: 9.5 out of 10 on price, its best score.
Pause Hardware, in two sentences
An attractive price, among the best in its category.
GregoryPause Hardware, October 2023 Overall, the power supply proves quiet; it could have been quieter still had it featured a Zero Fan mode.

Its successor: the MRR-1300AP (VP2)
Same wattage, same Platinum certification, same ten-year warranty, to the ATX 3.1 standard.
Hardwarecooking's gold medal
Voltages recorded with an RTX 4090, price with no rival: the first test of the MRR-1300AP. Pause Hardware's review can be read in full on its site.
