You should be able to connect the 2 PSU's so that they turn on at the same time all you need is an adapter. I've seen them somewhere but I cant remember where. The thermaltake GPU dedicated PSU has one...I think.
As for the PSU (if you have got the cash) go for a Thermaltake Toughpower Cable Management 700 or 750W. These work great, i just bought the 750W model and its awesome. It's got a 14cm fan for maximum silence, the cables are sleved and it comes with a gell pad that you put between the PSU and the rear of the case to minimise vibration noise. Oh and it's black appart from the badge on the side. It only cost me $239 AUS.

Or you can get the 600W model but that doesn't come modulised.
Modular PSU's are bad because the connection from the wires to the PSU adds unnecisary resistance the added resistance is as much as 2 feet of wire... doesn't seem like a big deal, but in actuality it may cause system instabilities.
Ohms LAW:
Ohm's Law defines the relationships between (P) power, (E) voltage, (I) current, and (R) resistance. One ohm is the resistance value through which one volt will maintain a current of one ampere.
in other words to increase resistance decreases amps, which people generally don't talk about amperage in computer terms you see wattage more often (amps = the square root of watts/ohms(resistance) or amps = watts/volts[in a perfect system that has no resistance you can simply divide watts by volts that is]) everybody loves to throw around wattage, when in reality amerage is more important.... of course we never have to figure out amps for computers because we "know" that our 12v runs at 12v our 5v runs at 5v etc. but when you throw in more resistance for the fun of it you are actually "suffocating" your computer parts and adding unnecisary stress to them.
Of course there is also the long term affects of a modular PSU that is run in a moist area, or is plugged in and out often, this can lead to loosening of the plugs or corrosion which can then lead to fun little fires inside your computer... can anyone say case lighting?
Of course, it is up to you... if you would prefer for your computer to look purty get the modular... you will never see one near my computer, but that is my personal preference.

Well, I've had this one in here for 2 years and it has been by far the best powersupply I've ever used, so I have no problems with modular. Besides, when there are modular PSU's out that are getting good professional reviews, I see no reason not to get one. I've been looking at the Enermax Liberty series, which is made for dual cpu systems, so I'm sure it can handle a large workload.

You can always make your own modular PSU's. I've done it, although I never posted it here because it's such a trifle.

Nearly all well made modular PSU's use gold plated crimps to connect and even if they didnt, as long as nothing really bad (like a dodgy crimp) comes into play, the resistance from a join would be hardly anything at all (if anything). A multimeter can prove this.Originally Posted by archmaille
Saying that a join in the wire is going to put sufficient stess on a PSU that will result in system instability is untrue. You create a join when you connect a PSU connector to a harddrive, motherboard, optical drive and graphics card. Unless your going to go round hardwire everything together with solder you will always have joins in the loom, joints which have no impact on system stability whatsoever.
And how the hell would a loose crimp lead to corrosion and setting fire to your case? If corrosion was going to happen it would happen on all the exposed parts of your motherboard ect, and INSIDE the PSU, not just the crimps, if the crimps became corroded they would not set on fire, they would probably just fail to connect. Besides, if you run your pc in a moist enough area to get corrosion woithout using moisture filters your an idiot and deserve to be set on fire.
You _can_ use two. Just short out the pins on the second PSU so that as soon as it gets power, it's on. Then make the other PSU work via the power button.
Or you can get fancy and splice the 2nd PSU's power switch lines into the first PSU's, which might work, but I would suggest the first, as I have no idea what i'm talking about.
My dad runs two PSU's, one for mobo, opticals, soundcard, videocard, and the other for all the fans and also the HD's.

If they use gold plated connections than much of what I said is irrelevant, being that I've never used a modular PSU I wouldn't know, and I've found nothing on any site that says in the description that they are. System instabilities from a brand new motular PSU is highly unlikely from the amount of resistance that it adds to the wire, but from one that is faulty or loose yes it could. As far as running this risk with any PSU because you connect it all over this is also true, but the resistance, and chances of failure are doubled with a modular PSU. The only reason I pointed this stuff out is because most people don't look at these things, but for a person like myself that prefers performance over anything else it may be important. I'm not saying that a modular PSU will most definitely destroy your system, all PSU's run that risk of doing very bad things to your computer, but my question is why put additional risk into something that you've spent so much money and worst of all time on.Originally Posted by FyR

The Silverstone TJ07 can hold 2 PSUs too and comes with a cable. This is what it looks like:Originally Posted by scraggles
So I guess that is the cable you should be looking for.
Just wondering, wouldn't 2 PSUs be better and cheaper? Like getting 2 Antec NeoPower 550 PSUs would be way cheaper than getting one PC Power & Cooling 1KW PSU.
