Community Reviews

This MSI MPG A850GS is an A tier 850 watt PCIe 5 modular power supply that stands out for strong value at the current price. The same price is available on Amazon, and the MSI rebate has a paperless option. The 1000 watt version of this model is described as running cool and quiet, which supports the line's reputation. The main caution is coil whine, and the rebate delivery has drawn complaints, so the deal is strongest if those tradeoffs do not matter.

Common Questions (4)

  • Yes. The A850GS is identified as an A-tier unit, and the 1000W version of the same model line is reported to run cool and quiet. That makes it a strong pick for a high-quality 850W Gold modular PSU at this price.

  • Yes. The MSI rebate site has a paperless option, which avoids mailing paperwork. The rebate is also described as being delivered on a prepaid card.

  • Yes. The Amazon listing is reported at the same price and should qualify for the same MSI rebate, with marketplace sellers on Amazon or Newegg noted as the ineligible cases. It is also listed in an MSI Amazon gift-card review promotion.

  • It can have noticeable coil whine. One recent buyer confirmed a bit of annoying coil whine, so it is worth considering if you usually use the PC without headphones or speakers.

Nice price, but, I got this about a year ago for $65, no rebate.

How does MSI rank among power supplies?
Most of their units are a higher tier but not all of them. You have to research individual models. This one is A tier. So it's a fantastic option especially at this price.
I have the 1000w version of this model and It runs cool and quiet.

Good deal, they made my last one, an Antec Gold 600w and it was nice and quiet, seemed stable enough.

Where did you get it from for such a great price? It never made it to Slickdeals, no mention of it at that price going back to 2023.
