Box & Bundle
The product comes in a sturdy box with a PSU photo at the front and its model number. Inside, the protection is good, with packing foam surrounding the product. Moreover, a bag contains all the cables.
Product Photos
The PSU has compact dimensions, and the exterior design looks nice. On the front side, besides the AC receptacle, there is a power switch and a button for toggling on/off the fan’s passive operation. Around the back, the modular board has ten sockets, including two 12V-2×6 sockets, which are overkill for an 850W PSU, but MSI uses one of them to provide two dedicated 6+2 pin PCIe connectors. I wish MSI had provided the same option as the 1000W model.

There are two EPS, six PCIe 6+2 pin, and a single high-power PCIe (12+4 pin). I have to note here that one of the cables hosts a pair of 6+2 pin PCIe connectors, and it ends with a native 12+4 pin on the PSU side, so these connectors use dedicated gauges. It is a wise choice to offer two 6+2 pin PCIe, and MSI should also use it in the 1000W model, which only has a single 6+2 pin PCIe (but 2x 12+4 pin). The cables are long enough, especially the EPS ones, and the distance between the peripheral connectors is adequate, at 150mm.
hello i want to buy 850w psu, but i’m really confused for choosing which brand. the MPG A850GS is $123, the RM850X is $145, and the Leadex III 850W ATX 3.1 is $100. which one will you recommend between those 3?
I would go for the SF unit.
Hey, I’m debiting between the Corsair RM850x ATX 3.1 and MSI MPG A850GS PCIE5 850W which one should I choose if both at the same price?
Hey Aris,
Would you go with this or the Asrock PG 850w? CWT has been a reliable OEM but unsure about FSP and Asrock. Thanks!
Hello, want buy PSU. Corsair RM850x 3.1 or Asus rog strix platinum 850W ? What better? Thanks !
Corsair
Aris do you have any info for upcoming Ocypus ATX PSU, did they send you sample for Cybenetics certifications ?
Hi! Nope, they didn’t so far.
