Question: Is this fully modular?
Document: I like the fact it is fully modular unlike Antec's etc. It is also a single line 12 volt power supply which according to most experts is better than a multi line of the same wattage. So too, review tests show the X850 can handle up to 1000 watt loads. Highly Recommended.
its fully mod. the fan runs when it needs to run. plenty of cables. cable are little stiff and made for med case. even the package was excellent. this best of the best its why u pay the extra for it.
This thing runs a 290x and i7 oc'd just fine. It's completely silent and cannot be heard over any of my other case fans, Cougars and Noctuas. Being modular it makes for a very clean case, and the flat cables are easy to stuff between the case and side panel.
Great PSU.Well built, cool and silent.Modular cables clip in nicely.Flat cables were &#8220;different&#8221; to work with&#8230; not bad just different to what I&#8217;m used to. Had to stack the cables. But in the end it looks great.Highly recommend this PSU!
I looked around and read many reviews off some of the sites that i trust the most and they all love Seasonic power supply's. This one in particular is a great buy. I have had it for several months. The hook up was easy and my computer looks cleaner inside with fewer cables due to modular design. I'm glad i bought it.
I have not built a computer from scratch in several years. When looking for a new power supply this one made it to the top of the list. I remember the days when there were so many cables inside your chassis that were unneeded and you had to tuck them away so that they wouldn't get stuck in fans. This power supply is modular enough so you have bunch of cable options that you can choose to use (or not). This results in a clean build with no extra clutter inside the case.
this is bar none the best make of power supply out there. the packaging is exquisite, the unit is flawwless in its velvet bag it comes in and overall the best power supplies i have purchased and i have purchaed 5 PSUs here and nothing compares not even the top of the line corsairs or EVGAs
fan hasn't been on although I barely reach 200W with my computer... I guess I overdid it but I could say its future proofed
Worst part about the experience (so far) is that, I believe it killed my motherboards audio during  one of its surges. My motherboard did give me a surge protection notice, but I have no way of proving it was due to the faulty PSU. Would they compensate me should it kill my next motherboard? Probably not.I've been trying to contact Seasonic for the past two weeks (through emails and through their automated online forms), but it's all getting rejected.
Works well so far. Very quite 99% of the time. The rest of the time it is as loud as most ps are normally
Answer: 100% modular!. Excelent!
