That would be me. I've got two of those Rosewills - the review unit will be pushing a 6 card rig as soon as I figure out what I'm doing for a motherboard.
Seasonic has been 18 AWG on all cables for a while now. I'm trying to gently prod them into upgrading those PCIe cables. They're amazing PSUs, but not what I run in the dedicated mining rigs because they're not really intended or built for it. That said, I have a Prime Titanium 750W running the office rig, and it does mine. It uses two single connector cables to push one downvolted 290X to get around the wire gauge issues. I've also got a Seasonic 1050W mining a three card machine temporarily until I un-lazy myself and get that Rosewill in there. Again, using as many connections between the PSU and GPUs as possible.
I actually can't remember the last time I saw peripheral cables bigger than 18 AWG, actually. Even my Super Flower 1600s use 18. That said, I usually run two risers per cable and have never had an issue provided I use them with cards that don't take a lot of slot power. For cards that do pull a lot from the slot, I get the risers with actual PCIe power connectors on them. You don't want to pull 90W out of one Molex for 24/7 use.

Corsair 1200i 1200w psu's are 16awg...but have had 3 of the pci-e cables to y adapter titan cubes (2 cables per cube) go over the last year too boot anyway....still running 2 partially working titan cubes with Y adapters on a Seasonic
660w psu ..(4 cables) 18awg ...it seems ok the last 1/2 year ..still watching....(need 2 more of those server psu's with 15 awg wire and 2560 watts to replace yet)
Anyway I live for danger!
(thou working hard at getting the replacement server psu's up asap before I get bit in the ass again)
Always best to hum the below song when working on evil knc titan machines or any PSU's that burn out cables in any manner!

I was running a Corsair 1200i and an EVGA 1200 P2 with the y adapters on my titan. I have a first batch titan. all dies still good and i'm running original 2.0 version software. Two cubes on each power supply.
about 6 months ago, The titan would just power off. I had the corsair as the primary and the evga as the secondary. this happened a couple times, it would run fine for a day, i'd come home from work and it be shut off. So i made the evga the primary and the corsair the secondary. Just the cubes connected to the corsair would shut off. I'm thinking my power supply is going bad. I swap it out with another evga 1200 p2 i had on my spare parts shelf and it's been fine since.
a couple months ago, i'm reconfiguring a few miners, and i'm pulling spare cables from power supplies, and one of the pcie cables from the corsair is stuck... it was burnt and crispy in the socket.
I've had that happen with my previous 3 corsair 1200i's as well..probably 4 ports (toasty) had to kinda clean around them and replace pci-e but they still work
lucky or better port design on the corsair 1200i (likely the 16awg wire allows the y adapter to blow first) anyway the server psu stuff fixed that ..at 15 awg
wire on those you don't need the y adapter ....been a year they don't even get hot anymore...need to more to get up
not sure if worth it thou...my knc titans are probably dead man walking with L3's out...I had 1 corsair go out after a year they sent me a new one after I
sent in the old one with cables no issue there. So workable with titans..if barely (of course Titans were overclocked 2x past their design..orig supposed to be
250mh miner..then late so y adapter kludge 300mh miner...then too many needed to be RMA by not reaching their 300mh advertised rate...overclock again
to the 300m to make up for bad dies etc.........evil knc was evil indeed....
