Cables and Connectors

Here we have the already mentioned connector panel. Seasonic is using good-looking sleeving for all the cables. As with other X-series models, the 24-pin cable is split into two plugs. All peripheral cables are on the upper row; all 12V connectors (CPU, GPU) can be found on the lower row.

Cables and Connectors
Modular Main 24-pin 60cm
ATX12V/EPS12V 4+4-pin 65cm
PCIe 2x 6/8-pin 60cm
Peripheral 3x SATA 55-85cm / 3x SATA 55-85cm / 2x SATA 35-50cm
3x Molex 55-85cm / 3x Molex 35-50 / Molex to 2x Floppy adapter 15cm

It is nice to see that the CPU cable is very long, which is important for cases with a bottom-mounted PSU. Two PCIe connectors are a common configuration for 450-600W. Seasonic again uses reasonably long cables here. The shorter SATA and HDD cables can be used in HTPCs; the longer ones are perfect for larger cases. If you still need FDD connectors there's an adapter included; if not, set it aside. We like the way Seasonic offers different solutions for different PCs.

    I purchased a Seasonic X-750 a few weeks ago for my new desktop and I can honestly say its one of the best PSUs I've ever had. The fan never runs except during long gaming sessions and even then it only remains on for short bursts and is so quiet I never notice it. The noise of my last desktop bothered my wife in our shared office so I was trying to get as quiet a build as possible without sacrificing power and this hit the spot. I'm a definite Seasonic convert after using the X750.

    PS If you watch Newegg you can catch some great prices. I got my X-750 for $130 during one of their weekend sales.

    I second that. I bought an X-650 and was able to get it on sale for $110 with free shipping. I wanted the 460 Fanless, but was more than satisfied to get an x-650 and save $50. Consider me converted.

    By the way, with a new Sandy Bridge setup, I find that the fan almost never comes on, not due to defect, but due to super low power consumption. It takes a while under load to get the fan to turn on. Due to the proximity of the PSU to my head, I can tell when it turns on, but only with the sides off the case. The PSU is mounted in the bottom-front of my case and I discovered my fears of the fan always running were unfounded.

    The X series might be the finest yet. I feel like it's the highest end piece of gear in my computer. I can always get a better GPU or CPU, but it's hard to get a better PSU than these.

    This is a piddly little suggestion, but velcro straps instead of zip ties would be really appreciated. At work we used to bind up almost every cable we could get our hands on(sans Cat5) with zip ties in an effort to keep thing neat and tidy, but after a contractor came in and used some velcro there's no turning back. No longer do we have to bring a pair of wire cutters to every job and delicately snip away the zip ties without nicking anything else. On the other hand, zip ties are pennies each, and velcro isn't. It still would be nice on the flagship product line though.

    On another note, have Seasonic been working on any new small form factor SFX PSUs? Really looking forward to those too.

    I recommended my friend to purchase the X560 two months ago for a build I'm doing for him. The "cable ties" mentioned in the article are actually velcro straps. There are three of them. I personally own the X750 which did not come with velcro straps.

    Really? Nice! I was squinting at the one product shot in the article and thought I saw regular zip ties.

    Seconded! Would definitely be interested in a high quality + quiet sff psu for my htpc setup...

    Yes, not a whole lot of competition out there in SFX land. Silverstone has the SFX ST45SF, but that's the only thing I'm aware of.

    I know some of the Enermax PSUs come with velcro cable ties, so it certainly can be done

    I have lost every power supply I have owned in my personal PCs for the last 15 years due to capasitor failure. All of the caps were ones that were buried under a ton of wires coming into the power supply at the point where they are soldered to the PCB.
    With design I expect that problem to be history!
    The solid caps, great air flow over the liquid caps, and fantastic quality parts i expect this power supplie to "Rule Them All" !!

    For now anyway :)

    There's no doubt in my mind that Seasonic power supplies rule, and this model in particular is very, very nice. Well worth the money.
