It should go without saying, but I will mention it anyway. If you open this up and start cutting wires, good luck getting any kind of a warranty.
I purchased several of these to use for powering RC battery chargers. I have a total of 4, 2 in parallel then each parallel rail being connected in series. Just using the 12V supply is 16 amps each for a total of 32 amp per power rail in my setup. This works out to a total of 64 amps at 12v or 32 amps at 24v.
When I start loading these up heavy (50A @ 12v/ 600 watts) they put out a decent amount of heat, but they keep right up. The voltage doesn't seem to sag at all. Then again I'm using a fairly constant load, there's very little surge in my battery chargers.
To optimize for my purposes, I cut the 3.3v & 5.5v leads and tucked them away nicely inside. I then ran 8ga wire inside the supply and secured it all with zip ties. I also extended the power-on leads so that I can remotely actuate them from a switch panel. Even better, the supply will latch on without a load on the 5.5v side unlike many other switching supplies which require a minimum load. This means when running it on a genny there's no wasted power or extra generated heat. I added a cap at the point where I connected the two supplies. As of yet I have seen no issues with them "fighting" with each other's clock cycles when run in parallel.
Overall a good supply performing exactly as I had hoped so far. We'll see how they do after I've owned them a while longer and continue to abuse them with high current loads.
It's been a while since I've rewired a power supply and bought this slightly more powerful 480w replacement without even researching if it was compatible. Imagine my dismay after taking the old one out and putting this one in to see that my ancient asus was a 20 pin and this ps has 24 pins. Now you may note the product title has "20/24 pins" listed and that's because this works with both. Perhaps I'm just out of the loop and it's common knowledge that this would be compatible but if, like me, you've been out of the computer building game for a while then it may be worth stating firmly that, yes, this ps will work with your old twenty pin motherboards!
Putting in a power supply takes hardly any time, and if you've never done it before then you'll be shocked at how easy it is. Once done, all devices worked great and my original (non dell) Alienware booted up just fine. Sweet!
This is an excellent psu and you can't beat the price.
