Packaging and Parts
The Corsair RM550 power supply arrived securely packed inside a standard retail box that lists the unit's main features and specifications on the outside. In addition to the power supply the package includes a power cord, mounting screws, wire ties, Corsair case badge, Warranty booklet, Safety booklet, and Corsair products Solution Guide. If you want a User’s Guide you will have to download it from the Corsair website.
Note: The Corsair Link USB Dongle is sold separately.
What do you think, is it OK
What do you think, is it OK to use this power supply in bottom-mounted-PSU cases? My concern is fan outake in limited space and directed downwar.? On loads below 50%, what’s going to be with heat dissipation?
sergio: Fans in power
sergio: Fans in power supplies are intake, not exhaust.
2 pci-e connectors a
2 pci-e connectors a positive? That should be a negative. All 550w psu’s in this day and age should have 4 pci-e connectors.
Unless you plan on running
Unless you plan on running stuff like 2x 670 or 2x 7950, which is pushing 550W unit, I disagree.
2 PCI-E is IMO fine for 550W. Not so for 650W OTOH.
There are videocards coming
There are videocards coming with 3 PCI-E, so I think at least 3 would be a good number. 2 PCI-E should be the default for 400W units.
Many new cards come with
Many new cards come with 1×6-8 pin, because they are efficent.
You can do Asus Strix 970 SLI with this PSU for example.
Lee, on the Specifications
Lee, on the Specifications and Packaging page, the efficiency and fan noise curves show the x axis as sytem load (watts), but it is expressed in percentages of full load. Conversely, on the DC Load Regulation and AC Ripple page, it shows the wattage being drawn but would be more helpful in percent of full load.
Would like an article
that
Would like an article
that compares the cost between the common recommendation
by all to take a PSU that’s double your consumption
and a PSU that’s just enough above your system consumption.
Example for calculated comparison:
PC1 peek consumption is 380w – PSU is 450W.
PC2 peek consumption is 380W – PSU is 750W.
(both the same 80+ rate)
PC#1 would be far from optimal, but buying cost is low.
PC#2 is in middle of the bell curve efficiency chart,
but cost more!
since the drop between PSU #2 & #1 efficiency is just few percent’s would it make buying the more expansive PSU worth while, for the average warranty of the PSU?
Such article would greatly benefit PCPER community.

I would be very interested to know ..
What is the standing CURRENT drawn from 240V mains during computer shutdown for the RM550.
I have another supply that draws maybe 200mA from the mains but out-of-phase. PF in shutdown is close to 0. Hence only 2 or 3 watt power draw. But that standing 200mA from the mains does not allow a power-saver power board to sense computer shutdown and switch off other accessories (Monitor etc).
Maybe a small plus for my recalcitrant supply during computer shutdown could be that it actually performs a SMALL power-factor correction for the rest of the office 🙂
I love corsair Rm 550 and I
