I have an aging Alienware from 2004 that was a powerhouse in its day. So much so that when the 340 watt ps died I wanted to resurrect the PC rather than put it out to pasture.

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.

WARNING! THE FOLLOWING PROCEDURES VOID THE WARRANTY

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.

I gave this power supply a five star rating not because it is the best unit on the planet, but because of the exceptional value. Being retired means you watch every penny, something I would recommend long before retirement. This power supply fit my budget even on retirement income. The unit worked as expected out of the box but I found the fan noise to be a bit much for my personal application in a HTPC case. On the other hand I would expect the fan noise to be tolerable under most general applications. Logisys used a 2300 rpm friction bearing fan to move air through this unit. The fan itself has blade guards and the power supply case also had blade guards. The result was not a lot of air flow for 2300 rpm with all the turbulence caused by the many guards. My resolve was to replace the stock fan with a low noise bearing fan spinning at 1700 rpm, and to cut the blade guards from the power supply case in an effort to reduce air flow turbulence. I believe the resulting air flow is every bit as good as with the stock fan (maybe better) and the noise level is much lower, just what I wanted. I also checked the underside of the pcb for cold solder connections, everything looked good & clean in this regard. Yes, I pretty much tossed my warranty out the window with the above modifications, but ended up with a quiet HTPC system that doesn't interfere with my music.

It only has 2 sata power connectors on the same set of wires, not 2 independent sets of sata connectors on their own leads, as one might assume. It works fine, otherwise, and for the price, it's tough to beat. Just make sure you get a molex to sata adapter, so that you can use a separate lead for additional sata power connections:

I ordered 10 of these and what was pictured on the site was the Logisys 480 Watt Power Supply with a 120mm cooling fan but received a standard Logisys power supply with a single 80mm cooling fan. Even the box the power supplies came in misrepresents by showing a power supply with a power cord plug in and an outlet but the actual power supply only has the standard power-in connector as you'll see from the pictures I attached.
