Excerpt: My computer stopped working and I was swamped. I brought to staples, they tested it determined the problem and replaced the part while I waited. The new power supply is quiet and appears to be working great.
Excerpt: Dell PC failed to start up after extensive shutdown. Dell Technicians attempted to solve the issue twice. Service expired on the computer. Called Staples Tech. He addressed it same day and replaced power supply wit Antec VP 450 W power supply. Issue is resolved. Original Dell power supply had to be marginal for a long time.
Excerpt: 1. Easy to install. 2. Good ventilation with big exhaust fan. 3. Power enough to support four (4) hard drives (7200rpm) without raising fan speed and the power unit case still keeps cool or only slightly warm.
Summary: A lot of people greatly overestimate how big of a power supply they need to run their system. This should be just fine for the vast majority of systems as long as they don't have ultra high-end video cards, multiple video cards, or an unusually high number other components.
Pros: I bought this power supply for a 2nd system that I didn't plan on doing much with. However, plans changed and now this unit is powering an overclocked 4670K and an R9 280X with no issues.
Cons: It's a little loud when under the stress my system is putting on it, but it's not too bad.
Summary: The VP-450 is well built, meets specifications, and provided plenty enough power for my 3D RepRap Printer. with the two 12V lines providing 29A total, I'm covered! The 5V line needs to be loaded a bit, so I put a 20W 12V halogen lamp on the 5V line and it draws exactly 1A, improving the 12V regulation. And is it ever quiet! Highly recommended.
