.. why is this PSU so cheap? It's on at least one tier list as being A+ rated. It's 80+ Platinum. No idea if it has the latest connector for Nvidia, but I don't really personally need or care about that.
Sold and shipped by walmart.com, so should be a legit seller. Has a 10 year warranty. Returnable in store. What am I missing? lol
(I acknowledge there are some bad reviews.. but still sold and shipped by walmart. Maybe a bad batch?.. but come on that price still)
Why is this so cheap?
Idk it seems well regarded on tier lists and in reviews like: https://www.tomshardware.com/reviews/xpg-cybercore-1000-platinum-power-supply-review
The 1300w has good reviews on Amazon: https://a.co/d/gVbDtmL
How could it do well in those cases, but bad for Walmart folks?
Walmart presses harder for a deal, Walmart gets the units that passed QC but barely. Good enough to not have to call it B-stock but you don’t want to send it to your better retailers either.
From a logistical standpoint that seems like a major pain to do. Possible but idk if probable.
Let's say you want 1000 units. Lets say normal QC takes out 20% of units produced, now your manufacturer needs to make around 1250 units to ship. Walmart says they're only going to pay $x, and the manufacturer squeezes that buck by lowering QC on the run for wally to only kick out 10% of the units so they only need to make 1100. Only now roughly 10% of the stock is defective.
Unfortunately it's not a good idea to cross-compare PSUs within one series/model at different wattages because they can behave very differently.
Typically the higher-wattage units within a series/model have better performance, voltage regulation, efficiency, etc. - sometimes in small ways, sometimes in big ways.
That's fair. Still this one is also A tier on multiple tier lists like: https://cultists.network/140/psu-tier-list/ . They specifically list Cybercore.
Also just found it on Amazon: https://www.amazon.com/XPG-CYBERCORE-1000Watt-Cybenetics-CYBERCORE1000-BKCUS/dp/B09XMZF6GL
68 reviews: 4.4 stars. Reviews seem about as real as regular products.
Yeah. I saw that the ratings were good too. Not sure why it's priced the way it is. Maybe others are right in saying they're doing some QC deflation type stuff.
