The 550W unit we are testing today ships with 6+2 pin PCIe connector to power a single graphics card. All of the lengths are perfectly suitable for a unit of this capacity. It is OK for some, but it has caused a burn out for me in the past. Twice in fact. I run separate cables, always. Thank you all for the input. Sounds like it's probably advisable to add the second cable and sacrifice some cable management cleanliness. It truly should be one cable per 8 pin connection. If you look into the specs and details daisy chain cables are garbage and should not even exist. Connect only the cables you need for a cleaner build with easy cable management and dual EPS12V connections for wide compatibility with modern graphics cards and motherboards.
Storage tier List. Tier A for Moving files/ OS. Tier B for OS/Games. Tier C for games. Tier D budget Pcs. Tier E if on sale not the worst but not good. For a 550W power supply, Corsair manages to get in a pretty decent list of cables and connectors to make sure that you are able to make full use of the 550 watts that are available. The obligatory 20+4 and ATX 4+4 pin connectors are present as you would expect. Both PCI-E cables features 6+2 pin connectors, are modular, and are of ample length. i7 8086K, AORUS Z370 Gaming 5, 16GB GSKILL RJV DDR4 3200, EVGA 2080TI FTW3 Ultra, Samsung 970 EVO 250GB, (2)SAMSUNG 860 EVO 500 GB, Acer Predator XB1 XB271HU, Corsair HXI 850W.Obviously when measuring AC noise and ripple on the DC outputs the cleaner (less recorded) means we have a better end result. We measured this AC signal amplitude to see how closely the unit complied with the ATX standard. AC Ripple (mV p-p) i9 9900K @ 5.0 GHz, NH D15, 32 GB DDR4 3200 GSKILL Trident Z RGB, AORUS Z390 MASTER, EVGA RTX 3080 FTW3 Ultra, Samsung 970 EVO Plus 500GB, Samsung 860 EVO 1TB, Samsung 860 EVO 500GB, ASUS ROG Swift PG279Q 27", Steel Series APEX PRO, Logitech Gaming Pro Mouse, CM Master Case 5, Corsair AXI 1600W Titanium. Corsair recently launched a new range of semi modular Gold rated power supplies in 550W, 650W and 750W capacities. These competitively priced units incorporate high grade Japanese capacitors and a compact size of 140mm to fit into a variety of chassis on the market. Corsair are offering a full 7 year warranty. Next we want to try Cross Loading. This basically means loads which are not balanced. If a PC for instance needs 500W on the +12V outputs but something like 30W via the combined 3.3V and +5V outputs then the voltage regulation can fluctuate badly. Cross Load Testing
Low-Noise Operation: A 120mm rifle bearing fan creates less noise than traditional bearings, letting you focus more on the task at hand, whether it’s gaming or work. Its very rare but not unheard of for PSU cables to melt when using only a single cable on extremely high powered cards have seen it happen with Seasonic PSU´s before but as i said its very rare Semi-modular: Allows user to only use the cables they need for a cleaner looking build with better airflow I recommend everyone out there who's looking for a new PSU to close your eyes and buy it.. You'll never regret this.. You're getting yourself a quality product from a trusted Brand and You're also future proofing yourself to an extent.. Efficiency is excellent, peaking at around 92% at around 50% load. At full load, this drops to around 89.35%. Solid results.
Technically, this unit is a no frills semi modular design which dealt with our suite of tests without any failures. It did not exhibit any concerning weakness under real world usage situations either, it was able to deliver over 600 watts of power before safety measures stepped in for a safe shutdown.
Great Deal
