Corsair VX550 PSU


Today's need for extra power supply energy keeps increasing. We all want to have a stable and at the same time efficient PSU that can handle with ease our energy hungry hardware setup. With so many products on the market, Corsair's proposal for 550...

We feel that Corsair's VX550 Watt power supply is a great product with a very good price. At the retail price of $96, you get a powerful and at the same time stable power supply with several futureproof features.

Corsair VX550W Power Supply Review


Stability, efficiency, and reliability are the main things we look for in a computer power supply. Today we'll take a close look at a brand new offering from Corsair that promises all of these: the VX550. Will our expectations be met? Join us and see.

Stable rails ; Ripple or lack thereof. They don't come much cleaner ; Value! $100? Madness, it's madness I tell you ; Strong good looks ; Fully sleeved (well, 99%) on a budget? Sweet ; Japanese caps FTW

Loose screws? Not good

Thank you good sir.

Great Power Supply


As much as I like Corsair products, I probably will not buy another of their products that has a mail in rebate.

Power supply works good, and as usual Newegg is the best

Mail In Rebate is bogus

Top of the line quality


It works great. I have had this psu for 2+ years with no problems. Corsair is always my top choice for PSUs for their quality and dependability

Failed at low power loads


This PSU caused me a very frustrating week of troubleshooting! I really wanted to like this seemingly well-built unit from a reputable manufacturer. I explicitly bought from Corsair because I hate dealing with PSU issues. After all that frustration, I...

Seemed very solidly built - heavy steel, solid & long cables with nice sleeving. Quiet fan

The unit I got failed oddly at low power draws. It worked fine while playing games, encoding video, etc. However, when I switched to light web surfing, my entire system would randomly hard reboot ; Because this was in a brand new build, it took me a...

Really great keyboard, Looks good, functions very well, The next step up is mechanical from this thing, great keyboard all around.

Really good feel ; Good tactile feedback ; REALLY slim ; Looks Ok ; WAAAAY quieter than the keyboard i was using before, No more CLACK CLACK CLACK

It got a little clicky after about a month, but it hasnt got any worse ; Sorta hard to clean, because of the scissor switches

solid power supply... a bit loud though


everything works perfectly, the fan noise was my only issue but nothing to deduct for as i'd rather have a loud systems than an unstable system

Has all the connectors for all your needs and the quality is great. easy to install

a bit loud but not to the point where its annoying

Quiet, Excellent PSU


It is compatible with consumer UPSes (like, APC). I bought this PSU to replace another brand PSU, because that one kept shutting off when the UPS kicked in. This Corsair PSU has no problems with the UPS and stays on, uninterrupted. This PSU is good...

This PSU is very quiet. It installed fine and has never given any problems. Nothing more to really say here

None at all. It is not modular (so theres gonna be a little mess of extra wires), if that matters to you. Nothing a few ties (which are included) fix, anyhow
