Robust Power This unit delivers a robust 350W of maximum power for your rig. Dual +12V rails provide sufficient juice for your multi-core CPU.
Quality Build EMI/RFI power filtration system provides low noise/ripple for super clean and stable power to all system components. High-quality connectors provide minimal resistance and enhanced electric conductivity.
Silent Cooling Fan The low-noise 80mm fan produces a massive air flow that keeps your PSU running cool and always at peak performance.
This review is from: StarTech ATXPW350DELL 350W ATX12V 2.01 Power Supply
Pros: Closest to a one-for-one swap you can get without getting it thru Dell (made for Dell with a Dell SKU).
Plenty of length to the cable runs
Cons: SATA Power connectors are straight out and not L-shaped (would work OK for Optiplex models listed, but tight quarters for the next generation of models I have)
Plenty of length to the cable runs (on the con side, I have extra cable to fold/wrap up on the MOLEX connector run to make sure the cable isn't blocking airflow)
Other Thoughts: I bought one of these ATXPW350DELL Power Supply Units from a brick-and-mortar store. It was only after you open the box up do you see the instruction manual that lists what specific models it works in. In the Optiplex lines, it only lists GX280. This PSU is a direct replacement for it, as the HDD in them (Mini-Tower models, at least) are mounted right below the Optical drives, so the cables don't have as far to reach. Also there is plenty of room where the cables plug into the HDDs to allow for the straight-out plugs (as opposed to L-shaped power plugs).
I have an Optiplex GX280 and it has one cable run with two SATA power connectors, another cable run with a MOLEX (larger white connectors) and a floppy connector, and a third cable run with two MOLEX connectors and a 6-pin PCI video connector. The new StarTech.com PSU has the exact same configuration.
I purchased this new PSU to go in an Optiplex GX620. These cases are different in that the HDD bays are at the bottom of the front of the case and the case does not open like a clam shell any more. The old Dell PSU had two SATA connectors on one run, two MOLEX on another run, a floppy connector on another run, and the 6-pin connector was on a separate run. With some re-arranging (clip a couple zip-tie cable ties) the new StarTech.com connector works (this GX620 has two SATA HDDs, two Parallel/Molex Optical drives, and a floppy). As mentioned above the power connectors on the new PSU come straight out from the drive and do not make an L-shape like the original Dell OEM PSU. The L-shape is necessary for clearance to allow the side door panel to close. I found there is enough clearance between the connectors and the door panel on this GX620 if I route the cables to make an immediate bend (without putting undue stress on the connector). Some people may feel more comfortable with getting straight-thru to L-shape plug adapters.
I also have an Optiplex 760 (3 models newer in the same line) and it has 3 SATA power connectors, 2 MOLEX connectors, and one floppy connector (along with the 6-pin PCI video), so this StarTech.com PSU should work for it, also, with the purchase of a MOLEX-to-SATA adapter or two ($3-$5 each).
The screw holes lined up exactly to mount the PSU to the GX620 case. This new StarTech.com PSU doesn't have slots/tabs that mate up to the existing slots/tabs in the Dell cases, but with all 4 screws, it's secured pretty well.
The cables were plenty long enough to reach where they needed to go in these Mini-Tower chassis cases, once I clipped a couple of the zip-tie cable ties that held the SATA connector run to the MOLEX connector run.
The manual lists the following compatibility: Dimension compatible models: 3000 / 3100 / 4600 / 4700 / 8400 / 9100 / E310 / E510 Optiplex compatible models: GX280 Power Edge compatible models: SC420 Precision Workstation compatible models:370
Now to see how long it will last. The GX620 came out ~2006, so this OEM one made
