Reviewed in the United States on June 22, 2017

Size: 3.3" x 5.9" x 5.5"Style: ATXVerified Purchase

I purchased this to replace an AcBel HB9009 300W power supply that failed after about six years of continuous service in a PowerSpec B629 desktop computer. For various reasons, I elected to purchase the 350W StarTech unit, including making sure the available amperage at each voltage and rail was adequate and because it has a few more connectors. Even so, I needed a single Molex-to-SATA adapter to connect the second HDD I have installed. It works perfectly so far (about an hour). I was very concerned about this replacement because I cannot find any web-site anywhere that indicates what an appropriate replacement for the HB9009 and/or for a PowerSpec B629 was, but this did the job and I wanted to let anyone in the same predicament know that this worked for me.

I received it fast and installed it right away. The only issue I had was that plug for the CD/DVD drive wasn't the same so I had to leave it unplugged for now. I don't hardly use it anyway, plus I have one on my laptop to use if needed. I tried very hard to match all of the description to what I needed but didn't realize the different type plug for that one thing. Otherwise I am very happy with it.

Ordered on July 20th. Installed and system up and running on August 16th. Failed on September 13th after only 4 weeks of operation. Amazon return window closed on August 21. Worst power supply I have ever purchased and I have purchased hundreds. Have had very good success with other StarTech and do not feel this is typical of their products. Submitted an RMA to StarTech. Will have to wait and see.
Updated from a 1 Star to a 5 Star on Sep 22nd. I just received notification that StarTech approved my RMA and have shipment of a replacement on backorder until early October. I feel the fast response and not even requesting that I return the defective item at my expense is enough to a 5 Star. I must say I was presently surprised. Radom failures of any product can be expected and I don't fault StarTech for that. But I have to give them credit for their excellent customer service.

My Dell desktops power supply failed. I contacted Dell about a replacement. They said it would take 16 -24 weeks to get one. Way to long for me, so I searched the Internet and found Startech. They linked back to Amazon and I purchased this one for replacement of my Dell Dimension's failed power supply. It is well built, quiet and the perfect fit for a replacement. It also comes with a 3 year warranty. I would definitely purchase again.

i replaced the old psu in my computer. I chose this one because
1. the fan is on the back like the old one.
2. the specs matched the one on the old computer
3. the company makes good products with good reviews
The psu works flawlessly and is very quiet.

Mine were defective!

Reviewed in the United States on January 28, 2020

Size: 3.3" x 5.9" x 5.5"Style: ATXVerified Purchase

I had high hopes for this StarTech power supply and purchased several of these from Amazon. Unfortunately, I haven't had the best luck with them. So far only 1 worked and 2 had had problems. I still have one more unopened in the box. My PSU test equipment indicates the 24 pin mother board connection is only 11 volts instead of 12. When I install one of these units, it will NOT power on the PC. I sometimes get a foul odor from the PSU. I will be returning them unless I can get them to work elsewhere.

I used my last Antec Basiq 350 and it worked perfectly. Unfortunately that PSU is no longer available on Amazon. I am looking for an inexpensive substitute.

Forse non tutti conoscono quest'azienda, ma si tratta di una multinazionale da oltre 400 dipendenti che si occupa della ricerca e della fornitura di prodotti per l'informatica particolari (vedere il sito per maggiori dettagli).
Il produttore, stando al codice RU, dovrebbe essere ATNG Power, già fornitore di Kuroutoshikou (marchio noto in Giappone), Fractal Design, Rosewill e altri.
L'involucro esterno ha un aspetto solido, e i cavi sono tutti sleevati, robusti, e delle dimensioni dichiarate.
La ventola è quasi impercettibile, anche sotto sforzo, e l'erogazione di corrente sembra stabile (almeno per quanto ho potuto verificare da pc).
Non potendolo aprire non posso dire nulla sui componenti, ma per il resto lo consiglio pienamente.

This power supply replaces a dead one in an older computer. The connections were straight forward.
The fit was perfect. The power supply is relatively quiet. The original computer had two dvds one of which was a bluray/DVD player, the other a regular DVD RW. The replacement power supply had a single DVD cable hookup.
If I wanted both I would have to look for an extension with two hookups. I can survive with one. Good replacement for its price

Very good new replacement PSU! The mains switch is soldered; needed to cut it off and add spades. Took about 3 weeks to arrive; maybe reasonable, since coming from Canada. USA mains lead included, not UK, but have plenty here already. BUT disappointed that had to pay about £16 additional extra import VAT and admin cost; thought that was all INCLUDED in the purchase price from Amazon.
