Rated 5 out of 5

Hard to find made easy

I am so glad I found this power supply. I am into vintage and retro gaming computers and finding a power supply that is NEW that has high output on the 3.3 and 5v rails is extremely difficult if not impossible to find. I am so glad that Startech is still making these parts. I highly recommend to anyone who is building a retro computer that needs high output amperage on the 3.3 and 5v rails and wants a new power supply to power it all. Why risk it with an old, possibly faulty power supply when you can have a new one.
