Good for certain applications

I bought this Dynex power supply to upgrade a PC that I was installing a new video card on. The video card is a NVIDIA - GeForce GTX 550 Ti and required a 400W power supply according to the Best Buy website. I purchased this Dynex 520 watt power supply and thought that should be fine.
Upon installation of the power supply and video card, anytime the video would start working hard the computer would crash and go into a safe mode. The power supply just couldn't handle it. After further review of the video card's requirements I realized it could run on 400 watts but needed much more amperage. The Dynex was not up to the task. Not that there was anything wrong with the Dynex, it just didn't have the amperage I needed. That said, not many power supplies do. I had to step up and buy a Thermaltake SMART Series 850-Watt ATX Power Supply to get the amperage I needed.
So the Dynex is a fine power supply. Just be sure you check your amperage requirements as well as the wattage requirements. The amperage specification isn't mentioned very often in product descriptions or specification requirements. Check with the manufacturer of your components for the exact requirements before buying a power supply. I figured it out after reading the specs on the Nvidia box. The amperage requirement was not published on the Best Buy website where I purchased the video card.

Great power & great price
Posted by: Michael619 from: McAllen, TX on
I just put this Power Supply Unit (PSU) in my Asus CM-6730-04 to replace a 300 watt PSU. This is the first time I ve replace a PSU and all you really have to do is unplug and re-plug. I notice it has lots of extra connection just in case you need to get some add ons. I got this PSU because I will be add a 1 GB GDDR5 to my PC, so I need the extra juice. It also comes with a great ventilation fan to keep it cool. The notice level...wait, I could barley hear it. Yeah, its really quite. (Just a plus)
Oh, when reconnecting the cords to the motherboard the PSU comes with a 20 pin connection for older CPUs and an additional 4 pin connection that would be placed right next to the 20 pin for newer PCs.

Correct my previous review.
Posted by: Adamabc from: on
I have to create another account to write another review to correct my mistake in first review. I guess I had taken the 20 pin part as the whole 24 pin connector, that is why it was too small. I should have put the 20 pin part and the 4 pin part together to form the 24 pin connector(as shown in the image with white arrows). I guess this item can be used on my PC therefore compatibility is no problem.

To start off, Dynex is a terrible brand to look into for a PSU, there is a reason why its sold so cheap. its labeled 520w when in reality the output will be around -350w. With the Amperage so low(16-20A) this will not power is system that is anything over low performance.

Good power supply; easy to replace
Posted by: mchristino from: Baltimore, MD on
had to upgrade my power supply due to a new graphics card requiring a larger power supply. This one was a perfect fit for the OEM power supply. Suggestion for easy replacement: do NOT disconnect existing cables from original power supply right away. Instead, remove it from the case, move to the side. Install the new power supply in the case. Then one by one, take off the current power supply cables from the peripherals (hard drive, mother board, CD-ROM, etc.), and replace them with the exact same power cord from the new power supply. There are lots of options on the cables, and it's easy to confuse them. Make sure you know how to identify the #1 pin to prevent you from installing the cable backwards. Also, make sure the power cables are pushed all the way on. If you get an error message on boot-up, it's probably because a cable isn't seated fully.

Raw the power you will EVER need!!!
Posted by: wk2311 from: Phenix City, Al on
This is the first time I have ever messed with a power supply it was fast, easy, affordable, and POWERFUL!!!! Sorry but I can not get over what some extra wattage does for your computer. It made my system run smooth as silk, never bogs because of lack of power. I am running 2 Blu-ray drives, a 2.5 TB Raid setup for hard drive, never bogs. If you do anything, try this first and I only buy from BESTBUY.
Thank you for your time, if you buy this you will be thanking me.

Good Power supply for repair work
Posted by: 2fast4u2 from: Spokane Wa on
Got this to repair a computer I built for my Daughter, It is no power monster but for this application worked just fine. AMD quad core,1 tb hd asus mb 1 dvd drive and ATI hd3450 graphic card.It has1 mini two pin,1 graphic card supply2 molex,4 sata,1 20 +4 and 2 cpu connectors.The large size fan is a "bottom draw" and runs with little noise.I think the aux fans I put in the case are louder. She thought her computer was fried when "It started sounding like my tazer" Install is simple do recommend you have at least a mid tower due to the large bottom fan the ram is close in our application.

Good product, worth a purchase
Posted by: Jschwartz34 from: San Diego on
I've used this for a couple years, and it's done well. Runs a Phenom quad-core gaming computer effectively.
After a couple years, it is now making a grinding sound, but it does not seem to interfere with its function. I will be purchasing another, and I recommend that you purchase one too. Good value, good quality, decent life.

Nice and cheap PSU upgrade.
Posted by: KGomez79 from: Tri-Cities, WA. on
Purchased this PSU to upgrade the stock 300w that came with my system that I also purchased from BB. Install was quick and easy and runs like a charm. This PSU will power an ATI HD 6850 no problem.

Plenty of power
Posted by: Naildriver from: Tri Cities, Washington on
Plenty of power for the new graphics card and any future upgrades I may want. Don't mess around with stock power supplies. If you don't have enough power you cn ruin your computer or it's components.
