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.
