I've owned Corsair's VX550W PSU for some six-months. It has faithfully powered
the following system without so much as a hiccup:
.
MSI K9A2 Platinum Motherboard; AMD 5000+ Black Edition CPU (overclocked);
Dual Radeon HD3870 Vid Cards (Crossfire Configuration); Maxtor 15K Atlas II HD;
Two (2) WD6400AAKS HDs (recently added to replace two older internal drives);
Pioneer DVR-115DBK CD/DVD Burner; and Seven (7) 120mm Fans controlled by
a Sunbeam Rheobus Extreme. The VX550? Rock. Solid. Stable.

One of the best 550w power supplies available

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

Weakness: none apparent

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 to expel the heat and it is audible, but the sound is a low pitch and not distracting. The cables are sleeved and are long enough for bottom-mounted...

The cables are sleeved and are long enough for bottom-mounted applications like the Antec CM690 case.

Corsair's customer support is top notch. The next psu I buy will be a Corsair if they continue to provide products and services like this.

Ok, PSU!

Strengths: Sleek looks, heavy unit, all cords are well insulted, will run all the latest video cards, good tech support

Weakness: It doesn't keep cpu tower as cool as OEM did, would be nice if it were modular, makes drive chattering much louder

After reading the reviews for Corsair power supplies, I could hardly wait to receive my VX 550w. The unit was priced right to deliver high performance to my new video card. Well, it worked fine and silent until day 15. Now the drive searching noise is 5 times louder. To the point, I replaced the vx550 with my stock Bestec. This of course resolved the noise issue. Why is day 15 so important,...

Why is day 15 so important, because Buy.com has a 15 day return policy.

Corsair 550

Strengths: Quiet. Does what it supposed to do.

Weakness: None

I have had this PSU for about 2 weeks now. I have to say that this PSU is powering Geforce 9800 GTX+ with power to spare. Only have one SATA WDHDD,and one optical drive(DVD RW). Some folks have said they have had fan noise. But nothing like that here! Also, five year Corsair warranty is one of the best out there. Tried PC&PC 610 PSU but had to turn it upside down to fit in my ATX Raidmax case....

Tried PC&PC 610 PSU but had to turn it upside down to fit in my ATX Raidmax case. Did not like that at all. In my opinion, go with Corsair PSU!! Nice cable ties and case sticker. PS. Was able to hide other unused cables in empty drive bay for good cable mgmt and air flow.
