Product Overview VS550: The Entry-Level 240V Power Supply With High-End Features - 80PLUS WHITE

The Corsair VS550 is a great choice if you're building a home or office system with lower power demands, but you still demand the compatibility and reliability that Corsair is known for.

Real Power
The VS550 delivers a guaranteed 550 Watts of continuous power. With 0.99 Active Power Factor Correction, you get the peace of mind from knowing that your components are protected from uneven power delivery. And, a dedicated single +12V rail saves you from the hassle of balancing your components across multiple power cables.

Low Noise, High Efficiency
The 120mm fan is thermally controlled, so it only spins at maximum speed when it's pushed hard - and even at full load, it's pretty quiet. Smart design features like this are why VS550 offers up to 85% efficiency. Your PC system will generate less heat, and you'll enjoy lower energy bills.

Sophisticated Design
The black powder-coated enclosure and the black-sleeved cables give any system a polished look. You're building a PC, not a battleship, and with the VS550 you can avoid that look of unpainted steel that you'll find on so many entry-level power supplies.

Reliability You Can Count On
VS550 is backed with a three-year warranty, and you get lifetime access to Corsair’s legendary technical support and customer service. Features • A dedicated single +12V rail offers maximum compatibility with the latest components.
• Active Power Factor Correction (PFC) with PF value of 0.99.
• AC input from 200~240VAV.
• Over-voltage, under-voltage, over-current, and short circuit protection provide maximum safety for your critical system components.
• High-quality capacitors provide uncompromised performance and reliability.
• A three year warranty and lifetime access to Corsair's legendary technical support and customer service.
• Safety Approvals: cTUVus, CE, CB, FCC Class B, TÜV, CCC, C-tick.
• Conforms to ATX12V v2.31 standard, and is backward compatible with the ATX12V 2.2 and ATX12V 2.01 standards.

Rated 4 out of 5 by from Shocking Packaging This item arrived in good time, and with the assistance of YouTube I managed to get it all connected and working well. After the inital boot it's quietly running in the background, the fans running are hardly noticable. I was somewhat surprised and suspicious about the packaging though. It came in a plain white box with a Samsung label for a different item altogether! and inside bubble wrapped with ScanUK tape was the product. I had expected the Corsiar VS550 to arrive in its own packaging with specs and warantee etc! Saying that, the product looked very new so I did install it as I had paid for the cover. After an online chat with ScanUK I was assured that the guarantee would be honoured.

Rated 5 out of 5 by from Fixed my problem! I bought this PSU because my computer was acting quite oddly and it was either the CPU or PSU. Basically, the computer (the case) was getting extremely hot and eventually freezing or resetting. My guess was the PSU has it seemed the case was getting the heat from it. Well, I bought this new PSU and the problems have gone away! Thanks Scan!

Rated 5 out of 5 by from Server Build This is a quick little server we built for ourselves to help store data. Works incredibly well and for the price it's incredible. Add the RAM on and you got yourself a beast little machine.

Rated 5 out of 5 by from Great value! I love Corsair products, especially the VS550, very quite in operation and highly trusted for my studio PC/DAW. Plenty of connections, my only critique would be that it's not the most ideal PSU for cable management. But that can be addressed by purchasing cabling extensions which I will do at some point. Recommended.

Rated 4 out of 5 by from Good value for money Very good value for money considering other power supplies. Had littlebit of weird vibrations but ony for one minute (don't know why) but nothing else since I've started using it about a month ago. Silient and powerful enough for mos of the systems.
