OC3D's investment into review equipment

What is the board like?

Really simple to be fair. Just needs some molex and PCIE headers on it. The main problem though is carrying 30amps thru a PCB trace :s
 
Didnt custompc blow one of those up they hired a long time ago.... cost them a bloody fortune to replace.. user error .

Excellent piece of kit and as someone mentioned will be great for unbaised reviews.

Bring it on Jim :yumyum: reviews ahoy!
 
So the board is some molex to PCIE headers,its the 30amps being the big prob. Will do abit of looking around.

Yeah they do cost a pretty penny. Thanks for the headsup...CPC can keep well away from this one :p

The idea behind it is mostly to avoid me plugging PSU's directly into the load tester all the time as eventually something will break.

What i'd rather do is have a PCB full of binding posts on one side so I can connect most of the load tester outputs up to the PCB and then from the PCB have another set of molex/sata/pci-e connectors.

It will also allow me to convert that single PCI-E connector on the unit into 4 or more PCI-E plugs on the PCB.
 
Some quick digging into it,the pcb track would have to be aleast 57mm wide and then it depends of the copper substrate of the pcb sheet. Would it be wiser to make a form of flylead for connecting PSU to Test Box.

Pricey bit of kit, well over £1000? If it didnt come with a wheel at that price...

:D

Yeah, I could have easily bought a fairly nice OC3D company car instead :'(
 
Think it would be wise to scrap the PCB idea. The tracks would not be up to those currents and anything like that would only add room for error and inaccuracy.

To put it into perspective, cooker cable that goes into the mains is 30 amp, standard mains wire is 13 amp. You would need to use the highest gague cable you can find made from the highest quality copper. High performance audio cable would be a good place to look, if you can find some in the 40amp area lol. The connectors would also have to be high quality and very well fitted. Maybe worth scouting for some choc blocks that are rated for like 100 amp and use them to make a crude but effective circuit :)
 
Nice to see a PSU tester capable of taxing even the most powerful units out there. It'd be good to see a 1500W unit tested all the way. Nice bit of kit.
