This is the second one I've installed. The last one lasted a couple years. This one says "Dell, Inc" on the sticker unlike the first one so that's interesting. So basically my computer is on its 3rd power supply since I bought it in 2020. Head scratcher. I have zero computer knowledge and was able to DIY it myself.

When the "orange" light came up on my Dell Optiplex, I knew it was the power. This fit in perfectly and was EXACTLY what I needed. It works like a charm. THANK YOU FOR SAVING THE DAY!

I bought this power supply in December of 2021 for a Dell OptiPlex 7010 SFF that had developed the dreaded blinking yellow power button failure. This PSU slipped right into place perfectly and brought my faithful old system back online. Today, in October 2023, I had to replace it for the same issue. Still, given the price and ease of replacement, I feel I got good value, getting another 2 years of life out of my old workhorse 7010. When you consider most laptop batteries cost more and last less, I'll keep using my old computer as long as inexpensive PSUs that fit it are available. And since no " Bronze" or " Silver" rated PSUs are made that will fit this SFF Dell, this is about the best one can do to keep it running.

My moms old Dell pc died and this psu saved the day

Worked just fine

Power supply unit got fried after a power outage. Luckily found what what was wrong and it was the perfect part to replace it. PC booted on no issues. Great value and totally worth it! Saved me from buying a whole new PC.

As soon as I installed this power supply I noticed a faint electrical smell. It went away shortly thereafter so I wasn't too concerned. After 31 days of use it started having problems. My PC would shut down and then restart, and I don't mean shutting down by the user choosing to. It would just die. This was happening 6-10 times/day. Since it was 1 day past Amazon's return policy window when this started, I contacted the seller directly via email, twice. No reply. Then it shut down and wouldn't restart and the burning smell was back stronger than before. I emailed a 3rd time but still no response. I finally contacted Amazon to see if they could help. They refunded my purchase price and sent me a shipping label to return the defective power supply. Kudos to Amazon for doing the right thing. But Poinwer can't be counted on. Their business card states: WE WILL MAKE IT RIGHT! Nope!!!!!

Appears to be good power supply replacement. A previous one from another supplier lasted two years so we will see how long this one will last. Fit, form, and function are very good, but time will tell so 5 stars now can be much less. I would expect 5 years out of a supply (continuously on). So a star for each year would be reasonable - so 2028 sounds good.

Es compatible con la optiplex que da en la descripcion, funciona correctamente, es un equipo que uso 24x7, asi que veamos que tal trabaja, por ahora todo ok

DELL製『Optiplex 7010』の電源が故障したため購入。 互換品とのことで、形状・寸法共に問題なく簡単に取付けできます。 動作も問題なく壊れたＰＣを修理できました。 ただ若干ではあるが冷却ファンの騒音が純正品より大きいので、静音ファンに交換するため分解しました。 DELL純正品と比較すると、ペラペラな放熱板、ノイズフィルタが未実装、冷却ファン回転数制御無し等、簡素な作りで値段相応といった構造です。 ３～４年故障せずに使用できればコスパ的には合格でしょう。 手ごろな価格で電源の修理ができ、良い製品だと思います。 構造で興味深かったのがケース内面に謎の鉄板が接着してある事でした。 これは電気的・放熱的な機能があるわけではなく、見た目上の製品重量を重くするために取付けたようです。 「純正品並みに重いのは、良い部品を載せた高性能電源の証ですよ！！」というアピールをしているようです。 なんて涙ぐましい企業努力なのでしょう(苦笑)

The power supply has all the correct cables and installation went smoothly and it is working well so far. However beyond that a review is irrelevant since determination of quality is how long the thing lasts. Ask me to review it in 2 years !!
