    Chryonn, you asked about 12v rails (single vs multiple 12v rails). A PSU with a single 12v rail lets you power everything without checking which cables go to which rails. Depending on your system, a PSU with multiple 12v rails might require a bit of checking to ensure you are distributing the load in a way that won't trip overcurrent protection on any of the 12v rails.

    The selling point for PSUs with multiple 12v rails is safety: a problem on one 12v rail should only affect devices powered by that rail; everything else will be compartmentalized and thus safe from the issue. However, a number of PSUs advertised as having multiple 12v rails, in fact do not. Personally, when buying a PSU, I check prices on the specific PSU models I know to be good units, and then buy whichever one happens to be available at the best price.

    Quick suggestions: if you really require a modular PSU, the Corsair 850HX would be fine. If bang for buck is any concern and you are capable/willing to do some cable management, I'd grab a 750TX (that gets my first vote).

    Also, about hard drive space: I understand needing plenty of it. Besides archiving data of various types, I have a surveillance system consisting of ... well, between five and ten cameras recording to hard drives 24/7 and I keep the video for a while. Just saying, sometimes there are legitimate uses for it.

    Corsair HX 750 or HX 850. The cable system rocks and very efficient. With the 280 in your system, the 850 would be a safer choice, but the 750 will work.

    ok, many people are recommending the HX850W. i said i was leaning to that brand and make.

    as for that Antec link regarding the myths of mulit- vs. single rail 12V well, i do realise Antec would be making a play at promoting its own range of PSUs.

    surely if they are so concerned with single rail PSUs other (rival) companies would take heed. corsair specifically design their units with single rails.

    i've taken apart my fair share of old and cheap PSUs in the past and all of the rails come from one single source. i've not taken apart my OCZ GamerXtream just yet, which itself claimed 20A each on four rails, but i plan to and see if it DOES indeed have separate converters for 12V.

    The HX850 is awesome, but it isn't the best bang/buck... ofc I don't know prices in UK, but I'm guessing Corsair is a bit overpriced. If you have the money, go for it! hell, get the AX750 or AX850 if it isn't much more expensive

    Here's a "Wiki" synopsys on the whole multi-rail game. Basically, the ATX spec for safety is that each 12v wire should carry no more than ~20 amps while also meeting the ripple tolerances. There are a number of ways to accomplish this, and many manufacturers bend the rules.

    Wow, that was a long post!

    i'm looking at the AX version and it isn't much more expensive. i'm not looking for a good bang/buck ratio, just something that will power my current rig with something to spare and maybe transfer to a more powerful rig in the future.

    Hell, if you just want pure quality and power, the AX1000? LOL

    But the AX850 should be great then

    well, my budget isn't unlimited, and AX1000 seems like overkill. in fact looking back, the original 1010W OCZ GamerXtream seemed like overkill at the time, but the 12V rails only had a combined output of 74A, the HX850 is 70A. i guess the PSU people have really been hard at work perfecting the tech! i can't find any real differences between the HX and AX versions apart from fully modular cables

    Hmm, it seems i've hit an impasse: the old PSU dimensions are 140mm x 150mm x 86mm - standard size for an Antec P180 case. the Corsair HX850 is longer at 180mm, now this might not sound like a huge problem but the Antec P180 comes with a standard PSU cage, and if i did dremel it out, i'd have to re-arrange my Swiftech MCP655 pump which is bolted some 3cm away from it, not to mention the tubing might have to be swapped/cut. ok so i've been looking around for PSUs to fit my cage and found this one: Coolermaster Silent Pro 850W Modular PSU | Ebuyer..... it's slightly cheaper, offers a slightly less amperage of 66A, has the same single 12V line, flat modular cables, more or less everything as the Corsair. can anyone give me a good reason NOT to buy this one? bearing in mind my predicament.

    EDIT: i've had a look at my case and it can take longer units but, again, the water pump will need moving....it's late and i need sleep, that's my excuse

    I'm just going to mention this off the top of my head in case you're interested: I run Silverstone OP1000-E 1000w PSUs in a couple rigs here and they are rather small for the power they put out. Definitely overkill for your use but it doesn't hurt to mention it in case you want to check them out.

    DONT go Coolermaster... go Seasonic, Silverstone, XFX, Antec or Corsair IMO

    AX has higher efficiency (80+ gold) and is fully modular unlike the HX

    What do you guys think of the Thermaltake EVO_Blue 650W PSU?
    I mean in general, not necessarily for Chryonn's case.
    There's also a 750W version the you might be interested in Chryonn if it's recommended by these guys

    No access to the corsairs and silverstones I'm afraid, so am trying to decide between the EVO Blue 650 and the Thermaltake ToughPower 750W. Ideally, I think the EVO Blue 750W would be nice, but not an option! :'-(

    Thermaltake ToughPower 750W is a very good power supply IIRC
