Corsair RM750i power supply review - Product Showcase

As you can see there is plenty of Amperage thrown around, impressive (if configured that way) is the single +12V rail rated at 62.5 AMPs (x12V)= 750W available just on that rail. This PSU could hold two GeForce GTX 980 cards or Radeon R9 390X cards quite easily (if you don't overclock the GPUs or PC to badly).
 

Graphics card wise with our tested 750W model you get to play with a luxurious four sets of 6+2 Pin PCIe connectors, that's right, as that is plenty enough for two graphics cards with each two 8-pin PCI PEG connectors. What you will notice is the dark sleeved cabling with dark colored connectors, overall a good design that fits the dark theme and style. The cables all have a proper nice length as well, but we'll look at that on the next page. 

Being a modular power supply, the rear side of the PSU is all about modular cable connectors. You will spot two connectors for the single 24-pin ATX cable, connectors for the PCI Express and EPS cables, two connectors for the SATA/Molex device cables. There is also a single connector for the Corsair Link interface cable. With the LINK software application you can monitor load, fan RPM and thus configure your PSU in a single and multi 12V rails, we prefer a single rails these days.
