There are 2 OEMs for the RM series. Both have issues it seems. The CWT made RM 650 had some issues in testing from jonnyguru including two dead 5V wires at the ATX connector and substandard capacitors. The Chicony made RM 750 flat out failed in testing by HardOCP.
Oh, thanks for your reply. CWT is decent, they made my TX750 which I have no complaints about, but Chicony... are they the same Asian brand who made my old membrane keyboard?
Either way, I had no idea there's a PSU OEM named that. All I know is that there's Seasonic, there's a less awesome CWT, there's Delta and then there's the rest which no one cares about.
I was aiming to buy the RM450 for a workstation build
(i7-4770, 2x4 GB Corsair XMS3 1600 MHz, Intel DB85FL, Samsung 840 Pro, two WD Black 1 TB in RAID 1) - I now wonder whether it's a good choice. I've been tempted by a good price, 5-year warranty and a Gold rating, but if the OEM is bad... I'll scour the net for more reviews - if you have any more info about the RM series, please do share!
To be honest, I don't like where Corsair is going with all this. This new CS series, I hope it doesn't replace CX - I've come to rely upon CX430v2 in all the office builds I do and buy one at least every two weeks. Rock solid unit despite being CWT-built, and a great bargain too. CS is a dark horse, and right now I cannot afford experimenting. What happened to using Seasonic as an OEM, have they somehow pissed everyone off at once?!
