Corsair VX550 550w Power Supply


Corsair has a great reputation for being one the leading performance memory module companies in the industry. They are the providers of some of the fastest memory around, and it is no surprise that when they made the foray into the power supply market,...

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.

Corsair VX 550W Power Supply


What can i say, i purchased one of these guys from an etailer, and while testing it outside of the case, i noticed a low buzzing noise. It turns out it was the fan making the noise and this model seems to be famous for this problem, a simple fan noise....

very solid power with a high 12v rail, energy friendly 80+ efficiency, alot of cables, compatible with almost all motherboards, and a 5 year warranty

Not as quiet as my hx620, not modular (but this was advertised so i won't count it towards the rating)

Corsair VX 550W Power Supply


Others have done a thorough job of detailing the quality features of this PSU, so anything I could add in that sense might seem redundant. .What I WILL tell you is this:.I've owned Corsair's VX550W PSU for some six-months. It has faithfully poweredthe...

1) High Efficiency (up to 85%); 2) 41A on a Single, Stable 12V Rail; 3) Quality Japanese Capacitors; 4) Sleeved Cables

Corsair VX 550W Power Supply


Having coming in knowing that this was Corsair's value line of PSU's, I was pleasantly surprised at the quality of the unit and its packaging and accessories. Other than having to bend the thick cables around a little to avoid running them into my case...

Quality build, nice packaging, relatively low noise

Non-modular, very thick cables

Corsair VX 550W Power Supply


This is a great power supply, it has a 41A single 12v rail so it will provide clean, consistent power. It has a 120mm exhaust fan that is silent under all but most demanding conditions. If you put the psu under load for long periods, the fan ramps up...

high quality components, 5 year warranty, long cables, single 12v rail, 80%+ efficiency

none apparent

Corsair VX 550W Power Supply


I must say that this power supply meets my needs; A quiet,strong power supply that doesn't break down and works exactly as described. This thing is a workhorse. Having dual 6pin PCIe for SLIing is also a great advantage. This power supply is highly...

This power supply works wonders! It is strong enough to support my Q6600 OC'ed with dual SLI'ed 8600GTS cards

My only weakness is that it is not modular

Corsair VX 550W Power Supply


Sadly, many people who purchase a power supply for their computer buy the cheapest one they can find. This can be a costly mistake. All of your other expensive computer parts count upon the power supply for smooth, reliable power. A poorly made unit...

Rock solid performance, primary uses a Japanese capacitor, nice matte black finish, single 12v rail is rated 41A

Expensive when not on sale, but then all quality units are

Corsair VX 550W Power Supply


At first I was weary of the Corsair brand, but after reading a few reviews, it seems everyone was spot on. The feature I was looking for in a PSU was how quiet it would be due to the position of where my computer would be in my room, this PSU was...

quiet, lengthy cables, # of connections, lifetime warranty

not modular
