3 out of 5 eggsGreat... When it worked

Pros: Price, form factor, quiet

Cons: Failed about 2 months after very light use. Whole PC only uses half of the total advertised wattage.

Other Thoughts: PSU failed after a storm, I will give it the benefit of the doubt that he power was fluctuating and was messing with our TV and other devices but the PSU should be able to take it. Besides that the computer ran well and had no issues, then "pop" that night it went out. Loud pop with burning smell. 3 stars because it didn't burn my house down.

Phenom II x4 965 Black (stock clock)
Gigabyte 970FX board
8Gb Adata RAM
GeForce GT610 fanless video card

UPDATE: Replaced with CM430 and has been working for a solid year with several storms and power outages. Just get something better, a PSU is not something to cheap on.

1 out of 5 eggsMost unreliable, damaging CPU to ever use

Pros: Came free with a $30 case

Cons: Caused my PC to crash any time a game was played, probably due to insufficient power with my 750Ti, a 50W card.

Caused my CPU temps to get into the 100 degree level because the PSU was giving too much power on the 12v rail.

Short, impossible to manage, ugly wires

Runs very loudly, even when the computer is idling

Other Thoughts: I had to use this PSU for almost a year because I couldn't afford a new one. It has caused many problems and probably almost caused me $200 worth of damages because of how inefficient and dangerous it is. Read the other reviews on this page, and save your money for something like CM, Corsair, or a FXF PSU. You'll save much more money and trouble down the road.

How Diablotek is still a company is beyond me

1 out of 5 eggsAvoid at all cost

Pros: - cheap

Cons: - died after 8 months
- Diablotek does not react to RMA request
- Diablotek did not state that 3 yr warranty is only given when buyer registers product

Other Thoughts: What does a 1 year or 3 year warranty do good when the manufacturer outright rejects to communicate with customers?
Do yourself a favor and buy a power supply from a different vendor.

1 out of 5 eggsWorked great... for a month

Pros: This power supply was affordable and fit the specifications for what I was looking for for my new pc build.

Cons: The Power Supply Burnt out under the average estimated wattage of approximately 233W in only a month.
At first the computer stopped turning on and I resigned it to a bad power supply.
Only to later have the power supply SIZZLE, POP, AND SHOOT HOT SPARKS ACROSS MY ROOM.
I was unable to return it to Newegg, so instead I contacted the Diablotek, the manufacturer, and they requested I send the power supply to them.
Luckily, I was able to get a power supply with a higher wattage.
I'll admit I should have gotten a higher wattage power supply, but I was under the impression that this 400W would be able to handle it.

1 out of 5 eggsGarbage!

Pros: Price and that is about it

Cons: Have had at least 5 of these fry - burn - pop etc. on me in the last couple of months...Purchased probably a dozen or more while building PC's for a couple of different clients - the particular model I have is actually PSDA450A which is not sold directly or was discontinued (purchased mine bundled with a case...) so I am leaving my review here for the 500W model and again for the 400W to hopefully save some people the headache this has caused me

Other Thoughts: NOT WORTH THE HEADACHE - These PC's were built as standard workstations for users in an office environment - no special power requirements - I was only using the Motherboard / CPU and one or two SATA connectors off of these supplies (most of the PC's don't even have an optical drive as we never use them any longer - one on the network is good enough in most workplaces and the others are all connected to SSD's so very little power draw) - I require high quality UPS units for every PC I build for my clients (cheap insurance and limited business continuity during a short term power failure) and in the two particular locations where these have been failing on me they also have line conditioners at the panel for the PC dedicated circuits so I know that utility company issues played no role in their failure. I'm a firm believer in you generally get what you pay for and to be fair the price was right but taking a longer view it has not been worth the damage to my reputation over failed power supplies with these clients. Fortunately the fix is quick and easy and I have absorbed the labor in switching the failed units out - I have actually ordered replacements for all the others that I am aware I have in service and have been switching them out when onsite for other reasons as a precaution going forward.

1 out of 5 eggsEl Diablo gives up the ghost in 8 months

Pros: So light in weight that I can pick it up with one finger

Cons: Lasted 8 months before it blew... but it gave me plenty of notice it was going to die for the two weeks leading up to its death. Every morning when I turned it on the fan would screech and labor hard to get up to speed.

Other Thoughts: I suppose I got 8 months of value out it so I am not all that bitter, but I would never put this quality of PSU in a mission-critical situation.

5 out of 5 eggsSo Far So Good

Pros: Does what it needs to, performs as I want it to. Having two fans can be rather helpful, and having two hasn't made it noisy either.

Cons: None so far, but i've only had it for a month. I will say the power cord that came with it is kinda short, only a 4-footer.

Other Thoughts: I bought two of these, second one for my friend, to replace our over-used, under-powered PSU's, and so far, they've been good. The noise is practically silent (but seeing as my case has noisy fans, I haven't noticed a difference) and installation was easy. Definitly the way to go if you want a cheap, but reliable PSU.

4 out of 5 eggsNice economy power supply

Pros: Very inexpensive. Works well. Not quiet, but not noisy. You can hear it easily, but it is not a nusiance. Good for a medium-small case or smaller. Has all the plugs necessary for an old NForce 2 motherboard that I installed it in.

Cons: I personally have no cons with this power supply, but I replaced a unit in a medium sized case. The ordering of the cable ends should of been different to be more accomodating. In a larger case, I would of had wiring issues, such as length and connector ordering on the wires.

Other Thoughts: Deals like this unit, I always appreciate for aging equipment.
