80 Plus Platinum Power Supply Units

The 80 Plus Platinum PSUs here run from the compact Corsair SF750, a 750W SFX unit for small form factor builds, to large ATX units for high-wattage systems: the MSI MEG Ai1300P PCIE5, the Cooler Master V Platinum 1300 V2 and V Platinum 1600 V2, and the Corsair HX1500i. All five are fully modular. Platinum certification means at least 92 percent efficiency at half load on the standard 115 V test, so less power is lost as heat and fans can run slower.

Choose by form factor first. The SF750 is the only SFX model and suits mini-ITX cases. The rest are ATX units sized for flagship graphics cards, multi-GPU work or heavy overclocking. The MSI unit lists PCIe 5.1 support and the Cooler Master V2 units list ATX 3.1 support, which matters for current high-draw graphics cards. Warranty varies by model: 12 years on the Cooler Master units, 10 years on the MSI and the HX1500i, and 7 years on the SF750. The 750 watt model has its own filter page, and the Corsair and MSI Platinum units have brand pages.

Frequently asked questions

Will the Corsair SF750 fit an ATX case? It is an SFX unit, so an ATX case needs an SFX-to-ATX bracket. Otherwise, pick one of the ATX models.

Do I need 1300W or more? Only for very high-draw systems, such as a flagship GPU with a high-end processor, or workstations with several cards. Most single-GPU gaming builds need far less.

What does the i in HX1500i mean? It marks Corsair's digitally monitored version, which reports power and temperature data to Corsair iCUE software over USB.
