There are three ongoing promotions this model psu is eligible for:
First, a $20 steam code for registering your psu, providing proof of purchase, posting a review on the retailer you purchased it from, and linking the review: https://us.msi.com/Landing/join-s...ut-for-msi
Second, a $10 steam code for registering your psu and providing proof of purchase: https://us.msi.com/Promotion/empo...st?link=
Third, since this psu comes with two pcie 12vhpwr (16-pin) connectors and only a single pcie 8pin (6+2) connector, msi currently has a promotion for a free pcie 16-pin to dual 8-pin Adapter Cable for registering your psu and providing proof of purchase: https://us.msi.com/Promotion/full...your-build
Please read the terms and conditions of all promotions carefully. While the terms for each individual promotion state "Participants may register and make up to a maximum of one (1) redemption per eligible product line purchased", I see no mention of not being able to qualify for multiple different promotions with the same product. In the MSI Shout Out Promo reddit thread, a member of the msi usa marketing team said that the previous new era promo stacked with the shout promotion as long as the product was eligible for both, lending further credence to the idea that you can participate in multiple promotions with the same product. That being said, I obviously have no way of verifying for sure that you can stack all three promotions this psu is eligible for, so ymmv.
This psu is A-tier on spl's tier list: https://docs.google.com/spreadshe...RB6

If this psu goes out of stock on amazon (or you just prefer newegg for some reason, such as for the "black friday price protection"), it's on sale at the same price of $110 on newegg currently: https://www.newegg.com/msi-atx12v...681770
Community Reviews
MSI's MPG A1000GS is a well regarded 1000 watt, PCIe 5 ready power supply that stands out for strong real world headroom and a solid tier ranking. It has been run with high end builds like an RTX 4090 and even a founders RTX 5090 without issues, and the current price looks especially good versus earlier pricing. The deal may get better if the MSI Steam and adapter promotions stack, though the promo terms are limited and require registration and proof of purchase. Connector compatibility is the main watchout, since the newer 12V 2x6 and 12VHPWR style plugs reduce older PCIe and CPU outputs, so it fits best when you actually need a 1000 watt unit.
PC builders who are planning a 1000W-class, Tier A power supply because commenters say the A1000GS is "A-tier" on SPL and that it's a great deal specifically if you need a 1000W Tier A unit.
Gamers running very high-end GPUs (like a 12700K + 4090 or even a founders RTX 5090) because commenters report the older 1000G version "fantastic" for a 12700K + 4090 and that the deal PSU "runs my founders RTX 5090 with no issues."
People who want to take advantage of MSI's registration promos (Steam codes and the free PCIe 16-pin to dual 8-pin adapter) because one commenter says the deal is excellent "assuming you're willing to register the psu with msi and jump through hoops" and lists multiple eligible promotions.
Buyers who prefer buying from Newegg over Amazon for PC parts because one commenter says they'd choose Newegg and cites receiving fewer "New" items that were actually returns/missing parts compared to Amazon.
Builders with a pre-2022 GPU and an MSI B850M Mortar who need the PSU to provide enough compatible PCIe/CPU connectors because a commenter argues the 12x6 (12vhpwr-style) setup "looks like it can't handle my b850m mortar and a pre-2022 video card" due to not enough PCIe/CPU ports.
People whose system only needs around 850W and won't upgrade to 1000W because one commenter says they'd "personally lean" toward a be quiet! 12M 850W instead, citing tighter OCP/OPP protection thresholds than the A1000GS.
Buyers who are sensitive to marketplace/return risk and don't want to deal with Newegg sold through Amazon because commenters say they avoid Newegg on Amazon (citing "24% one-star ratings" and perceived decline) and plan to pass on the deal.
People planning to buy multiple PSUs expecting multiple Steam gift cards because one commenter warns the MSI/Steam promotion is limited to one Steam gift card per product category (e.g., buying 2 PSUs yields only 1 Steam code).

This was the most recommended PSU. MSI bought out the EVGA team making the good PSUs they had.
EDIT: Had to put N/A for apartment building section instead of leaving it blank because I live in a house, kinda silly.
