1,300 W, 80 PLUS Platinum certification, ATX 3.0 standard and a 12VHPWR connector for under €190: Hardwarecooking hooked our power supply up to an RTX 4090 and an i9-13900K. It leaves with gold.

A single rail to carry it all
108 amps on the 12 V, that is 1,296 W available for the processor and the graphics card.
The MRR-1300AP is a fully modularpower supply, to the ATX 3.0 standard and PCIe 5.0. Its 12VHPWR connector powers a 40-series GeForce RTX without an adapter, and four PCIe 6+2-pin connectors serve other graphics cards.
A single 108 A rail on the 12 V, six protections (over-voltage, under-voltage, over-current, overload, short circuit, overheating) and a 140 mm fan with RGB lighting, syncable with the motherboard.

The test bench: an RTX 4090 and an i9-13900K
Hardwarecooking doesn't test power supplies on an electronic load, but on its reference build: a Core i9-13900K cooled by a 360 mm AIO, a GeForce RTX 4090 Founders Edition, a Z790 motherboard. It pushes the unit with OCCT's power supply test and reads the voltages with a multimeter, at idle then under load.
All three rails stay within 0.16% and 1.51% variation. According to the author, there is no risk to components — the ATX standard allows 5%.
The real argument lies elsewhere: around €190, where the other 1300 W Platinum power supplies cited in the review start at €300 and €350. As for the drawbacks column, it contains nothing but a question mark.
From every side
Hardwarecooking’s verdict
This M.RED MRR-1300AP power supply therefore earns our HC Gold award.
Cyril KleinHardwarecooking, 21 September 2023 Suffice to say, the competition is all but non-existent

The MRR range, in VP2 version
The MRR-1300AP has given way to its VP2 version, to the ATX 3.1 standard and PCIe 5.1, still 80 PLUS Platinum, still with a ten-year warranty.
