Ultra LSP550 550-Watt Power Supply - ATX, SATA-Ready, SLI-Ready, 135mm Fan

Comment:
Installed in a blink, working like a charm. I would rather have had the model with detachable cables, but my old motherboard has a 20-pin socket. Guess I'm living in the dark ages!

pro quiet good looking ample power for everything cons no 8 pin pcie

I ordered one of these supplies, and the 5v standby rail was dead when I received it. Ordered a second one, and it is also dead-on-arrival, although the 5v standby rail does work on the second one. I will NEVER order another Ultra power supply again! By the way, this is the primary distributor for this brand!

It's been the best power supply I have bought had all the hooks you needed installed it power right up and ran smooth. It's been about a month and still working good. I would buy another one in a heart beat.

I bought this to upgrade my 2005 P4 emachines computer. Installation was a breeze, although it was a tight fit. The size of the casing was a determining factor for me and this fit the bill. Its quiet and still moves a considerable amount of air, which Im sure will help with my heatsink style graphics card. Very nice product.

Love this thing. No problems at all. Runs my Intel Q8400 system smooth.

Comment:
old PS was trash. This PS is by far better than old plenty of cable an connections . runns smoother an quiter than my towers 3 internal fans. have a gaming puter i built from bone up lots of mult. components an this PS does it with ease!!!

Comment:
needed this one because old power supply didn't match the 8 pin plug for motherboard power. Plenty of connections, quite enough and good value.

Comment:
I've been very pleased with this product so far. Only reason it gets a 4 on features is because I wish some of the cabling was a bit longer, as another buyer commented they needed an extension. I was fortunate that I didn't but the cable is barely long enough in some cases.

Comment:
I was clear from the packaging as well as the cables that this is a great product. So quite! I recommend it.

Comment:
very pleased with this power supply, bought one for a new computer for added video card, then bought one for old computer, well made I like the large fan plus my cases are bottom mount power supply

Comment:
Most Suitable for Mid-Tower. The overall material and assembly quality is surprising for a product at this price range. The number of connections for SATA, PCI-E, etc, was exactly what I was looking for. But next time I will go for a modular device. Easy Installation without a single problem ! Ultra do not mention the size ( like many others ) of this PSU we have to search around...

Comment:
I found it to easy to install. Plenty of wire for all connections and plenty of instructions to go along. I would recomend it to everyone. Edward Miller

First one was dead on arrival. Replacement works great.

Comment:
This is the third one I bought. The big fan on it is soooo quiet. Fit into the tiny Dell Dimensiion 3000 Case.... because of the AGP card that needs it own power connector, I had to also use an extender to power the hard drive. But thats minor and has nothing to do with the item and how it works

Comment:
Arrived when promised, out of the box, installed and running in 15 minutes, clean power, more than enough connections of every kind, quiet fan. I'm gruntled.

Comment:
Solid PSU and extremely quiet, plus the 135mm fan should keep the inside of the machine cool.

Comment:
This is a well built power supply. It has plenty of outputs for many components. Everything fit perfectly and it had every variation of power supply connector for any mobo, graphics card, disk drive, ......

Comment:
Took it out of the box,installed and turned on with no problems at all. Recommended!!

Comment:
Cannot beat the price and warranty.. It's as simple as that.

Comment:
Runs nice and quiet and provides steady power. Has all the pugs you need these days and even has all tha cables wrapped (I'm used to only seeing the main 20.24 pin power line wrapped). Looks nice too, but I never see it...

Comment:
I recently purchased this power supply for my new build and it hase been great. No problems just yet.

Comment:
