Logisys Power Supply Upgrade for COMPAQ PRESARIO SR5100 Series Desktop Computer - Fits The Following Models: SR5102HM, SR510

I received the power supply in three days and it was not an expedited order. I was impressed. The supply was was easy to install and with the exception of having one more pin installed in the plug than the original supply it was a stress free installation. I was able to determine that the pin connected to a ground and was not a problem. I fired up the cumputer and it worked well. the higher capacity power supply was both a repair and an upgrade.Thank you for the follow up inquiry.

This was a great upgrade to my old computer. I bought a video card for the computer and it needed a more powerful power supply. This one works great! It came very quickly to my surprise. Thank you!

Easy to install; quiet; works fine. It's a good value for a replacement power supply for an old Compaq PC!

I really should wait to write this review as the warranty period is quite limited, i.e. one year. I fully expect this product to last at least two years, preferably five years running 24 hours per day, 365 days per year. I'll update this review if the power supply fails within the first year while running under my criteria. This 450+ watt power supply is a perfect replacement for the original Bestec 250 watt unit in my Compaq SR5113WM computer. My only gripe is the minimal venting on the power supply. As long as the interior of the case doesn't get too warm, I don't expect much of a problem. We'll see.

This PS does the job. The voltage outputs are fine and has all the connectors I needed. I tested the outputs with a PS dongle. I wish the connectors were of better quality, they look a little fragile to me and SATA connectors don't have a lock. I like the on/off switch. I believe the wattage is a little too optimistic. At the most 330 watts (are they using RMS values for calculations?). I just installed it. Compaq PC powered up correctly. Too early to say more.

Inexpensive, delivered promptly and fairly easy to install. This unit doesn't come with any directions but YouTube will show you how to perform a heart transplant, or swap out a burnt out power supply. The wiring harnesses are a little confusing so I recommend just disconnecting and then reconnecting just one at a time. If an old locksmith in his 60s can do this, you can !

Worked great but description showed a -5v but there was not -5v wire.

Just as described, more oomph than oem, no problem it compatability . They shipped it priority mail 2 day at no extra shipping charge. Very happy &satisfied with purchase & will use them again.
