Yeah....... Not so sure about this one. I mean Add2PSU adapters have been around for years and give the consumer easy control when adding one or more PSU's to the system. And there is no need for "splicing and or cutting" anything when using them.
This way you could theoretically connect as many PSU's as you wanted. I have three 1500 watt PSU's hooked up now in my personal rig and have never had an issue with my two $12-20 parts....

One use is that it could add redunancy to the system. With two manually connected PSU's, they would each deliver power to different components. But now, if one fall out, the Motherboard, CPU and GPU will still be operational, even if one PSU fall out.
Kinda like a cheap consumer edition of redunant PSU's on the professional marked. Not exactly something to my own taste, but there are probably people out there that could want something like this.
But for power distrubution, I can't se why you would want this.

it look neat... BUT:
-2x1000 PSU cost lot more than a single 2000 from superflower and need twice the space (or 1.5 as it is really big lol)...
-if you need redundance then pro PSU again is less expensive than 2 mainstream and take less space...
-if you are manic OCer then again there is wire adaptator that doesn't need cut, melt or anithing at less than 10Euro to do the job...
so it is really cool looking but i doubd about the success of this.

i run an overclocked crossfire system stable on a 760W 80+ Platinum (=92% eff.) PSU
STABLE. (its yet oversized because the maximum watt drainage i had was ~490-510)
someone still has to show me where (apart from 3way or 4way sli/xfire) anything above 800/900W is NEEDED. the introduction of SSDs (1-3 Watt max.) and the breaking away of HDD/CD/DVD-drives has already narrowed power usage down to mainly 3 main components that drain:
- Mainboard (regular 25-40 , high-end 40-80)
- CPU
Core i3 55 to 73 W
Core i5 73 to 95 W
Core i7 77 to 95 W
Core i7-E 130 to 150 W
AMD 2 cores 65 to 95 W
AMD 4 cores 65 to 125 W
AMD 8 cores 95 to 125 W
- GPU
Low End 25 to 86 W
Mid End 110 to 164 W
High End 162 to 258 W
Top End 240 to 375 W
includes dual gpu cards
soooo lets build a top end computer with a titan Z
80W mainboard
150W cpu
375W gpu
=605W
+50W "peripherals" (usb, ssd, RAM) where 50W is a real big buffer already
=655W
now if you have so much money for a high end rig, you will ofc buy a high end PSU (which is measured by high efficiency & quality of current delivery, not high wattage neccessarily)
so lets say also to be fair here... it has an efficiency of ~92%
so 655W has to be 92% of our PSU Wattage.
that makes our needed PSU -> 712W
So lets be modest and buy a 750W or 800W for that rig.
CASE CLOSED.
(if you build in a second titan Z ... 800 + 375 = 1175, 1200 is ENOUGH, most probably the system will never exceed 1000W in use anyway, even under full load)
i really would love to go around peoples rigs and just check with a watt-meter how oversized their PSUs are... i bet over 50% of gamers buy that overpriced **** just "to make sure its no PSU fault" as they are told in forums all the time...
QUOTE: "oh yeah thanks for the tip i bough a new PSU and the game still crashes" :bang: :bang: :bang:
90% of people have never seen a failing PSU and the symptoms...
like delayed cold start due to damaged capacitors etc...

I understand you said "to be modest, let's say 800W" but just to clarify, it is usually bad practice to get a PSU that just barely meets the estimated consumption of your PC, so even 850W is a safer choice. You usually want to give yourself at least an extra 100W or so of leeway in case of inaccuracies, inefficiencies, brown outs, aging degradation, and so on. There are people do triple or quad GPU setups, where 1500W is needed. There are also those who overclock everything, so if you have a multi-GPU setup with everything overclocked, you can get to 2000W. That in itself is pretty ridiculous, but going beyond that for a PC (even a workstation) is kind of stupid, in my opinion.
Keep in mind though, there are servers out there that can easily exceed 4000W.

Well, my PSU has just died, unpleasant downtime. Redundancy would be nice. And I know at least one case that can take it: Silverstone TJ11
