Customer Reviews

This PSU installed easily, more than enough cables, and the cable sleeves are nice.
B. Karczewski
Don't trust the malarkey of Diablotek and similar companies because they know they are selling junk.
Lusory Prime
This power supply is not making a hissing sound which I belive is the fan bearing about to go.

This power supply is incapable of delivering 550 watts of continuous power to any devices attached to it. You read that correctly, it fails to do what it advertises and in fact it fails so spectacularly that I retested it three times to ensure I was not at fault. If you read nothing else in this review, remember this: this unit can barely supply 350 W in cold (22 C) conditions and should be avoided along with the company that produced this travesty. Even the Underwriter's Lab hasn't certified this pile of lies.

I am a post-graduate computer engineer and I have access to load testing equipment at a local university. I bought this unit locally out of intrigue and decided to test it before using it in any of my computer systems.

However, before delving into the results of that test, I should go over the claims made by the manufacturer about this unit. In particular this unit claims the following output on the side of the box: +12V@30A, +3.3V@22A, +5V@32A which they claim all total to around 550W. Those are all, without exception, lies. If you look at the Diablotek website at the output of this unit (coyly called the "revised" specsheet) you will find a more honest output: +12V@18A, +5V@25A, +3.3V@20A. Another thing to note with the revised specs is that the total wattage has changed on this supposed 550 watt unit. In fact, the total wattage has dropped considerably to 407 watts (I assume this is peak power since they don't actually state it explicitly). So already we have one huge lie: this unit is not, by design, capable of delivering 550 watts. Reasonably, we shouldn't expect much over 400 watts.

I'll add a note here about +12V ratings reporting as it is a common tactic of crappy PSU manufacturers.

I purchased this power supply for a first time build. The supply has 6 SATA connectors (more than enough for my DVD burners and dual HDDs) and a 20 pin power connector for my motherboard that most other supplys did not have. The cables were long enough to reach all of the components in my case and fit fine. The only complaint (very minor) I have is with the some of the SATA connectors.....the connectors should be right angle to allow additional clearance for hard drive cages that are mounted close to the case cover.

I have another Diablo unit that I have had for about 2 years that hasn't given me any problems yet. This new I just bought is running my Phenom Black CPU. There haven't been any problems whatsoever.

I bought this about a year ago for a ZT Affinity computer. It burned out today.

Two previous 300W power units that ZT had supplied burned out after about 6 months each. So, it might be a problem with the ZT computer--though ZT couldn't find anything else wrong.

I had hoped a 550W power supply would do the trick. But, it only lasted a year.

I'm ordering a 600W Diablotek hoping that it's dual fans might give me more than a year.

Pros:

Looks nice, has a lot of connectors, low price

Cons:

Only worked fine for a week, it started giving low voltage on the 12V rail.

Thanks to Amazon for its superb customer service and giving me a refund.

I had to upgrade my computer's power supply due to the recomendations for a new 1-Ghg video card I was going to install. My existing power supply was in good shape but came up a little short when it came to output wattage. The Diablotek was husky enough to handle, not only the PCI Express video card, but I also added the first of what could ultimately be up to six additional SATA drives. The case made removing the old supply and replacing it with the Diablotek pretty easy, but what really helped was the way the bundle of wires comprising each indiviual connection was completely wrapped in a vinyl like webbing beginning inside the power supply and continuing out to each connection plug. It was easy to bind all the unused connections together and tuck them away beside the harddrive stack. As for the cables I was actually using.... I found this installation to be a much better experience than most. Routing a single web wrapped bundle around the motherboard turned out to be much easier and decidedly more appealing than having to deal with the usual mishmash of multi-colored little wires runing hither and throe over your motherboard, accessory terminal and drive stack.

The 450watt PSU that came with my case had it with the LED fans, constant used processor and graphics and two drives. This one handles everything just fine. I not only run the occasional games, and have multiple drives for storage, but also run Boinc applications that really demand power. This PSU installed easily, more than enough cables, and the cable sleeves are nice. It was very slightly larger than my old PSU, just enough that I had to relocate my top fan. No problem though, my temps were over 10c cooler with the large fan pointed down to all the hardware.

Bought this in may of 2012 and here in march of 2013 and the fan slowed down to near halt and caused a huge burning smell of components.The unit itself is heavy duty. Not unlike those cheap light units. Was a silent PSU and worked good before it died. It is written right on the side a three warranty. We will see what actually comes about that. Hopefully Diablotek will back this warranty and replace the unit.
UPDATE: Sent in for rma request on the 26th of march now it is april 2nd and still no outcome other than the reply of thank you for your request our staff will contact you as soon as possible. This is unexceptable. Steer clear of this brand as a warranty means absoultey nothing!
