EVGA 600 B1, 80+ BRONZE 600W, 3 Year Warranty,..GREAT ! Fits my Asus perfect
I bought this was a quick easy install into my Asus, Asus-D415MT-PC. Why there are many models of boards I like to give a reference when I can. This is heavy about twice my stock, which was 250W peak 300w. Comes with allot of connections for dual CPR, and dual Graphic cards. The cables on this are not port attached, some have plugs this is pre-wired, which is OK, but I knew that when bought it my case has easy storage for cables to tuck in and not be in the way. Pro: Simply design and install. Good cables not flimsy good rail specs. Good price. Cons : None really Overview, I could not find any cons, so far it installed in 5 minutes and was back up running, no noise. Left it run for some time checked all ports and working great. It has a three year warranty, this last PSU was over 5 years old in a top end machine. ( I know how could they say it was a top end with a 250w power supply that is because it was designed for business and now is converted for gaming. I need a upgraded video card and this power supply will take care of that easily for me. My old PSU didnt die, but notices some BSOD that seemed connected to power drops with kernal issues. I have been amazed over the years that many many box store and pre-made CPU's are powered by low watt or low quality PSU's. The reviews seems good and hopefully this runs well for awhile . EVGA, warranty of three years should be a comfort for many as in this day of age el3ectronics are built iffy at times. I will give an update if it changes how its performing.

***Excellant Economical PSU***
This PSU was just the right size for my barebones build, did a little homework before buying and pretty much using on line reviews and jonnyguru as a guideline choose this brand for the price and for the excellant test results that these EVGA SuperNOVAs tested out as. They are rated 80 Bronze and test out as Silver and with all Japanese capacitors and a very good PCB they really shine when under the gun. Super Flower being a collaborater doesn't hurt one bit as they are very highly thought of in the industry. Bottom line you just can't go wrong if you're budget minded and want a very good product. They are semi-modular if that is the right word, the ATX 24pin and ATX12v 4+4 pin, plus two 6+2 VGA 12v rails are hard wired the rest are modular and it comes with a slew of extra cables and ties. You have enough cables to do anything your heart desires. Being an 850w it is right on the threshold of being capable of x-fire or sli. I only use one gfx card but may OC and this baby is just the right power and built ike a tank, the 140mm fan with dual ball bearings is a plus and I found it very quiet under load. Highly recommend.

Very good quality EVGA 500w 80+ Bronze power supply for my Lenovo ThinkServer TS140.
I'm upgrading my Lenovo ThinkServer TS140 power supply to this EVGA 500w 80+ Bronze to power the new Gigabyte AMD R7 360 128 Bit GDDR5 2GB 2xDVI/HDMI/DP Overclocked Graphics Card (GV-R736OC-2GD REV2.0) ( https://amzn.com/B01DT48WSU ) that requires a 500w power supply. This is because I just purchase a QNix UHD3216R 4K monitor for my new desktop setup, which means a new video card is need to power that monitor's 3840x2160 resolution. Now I could of went with the EVGA 500 White for much cheaper but based on what I heard and read, getting a 80+ Bronze or higher is safer and will last much longer, so paying a little more doesn't hurt my pocket really. Now if you aren't in a rush to get a new power supply, then I would recommend that you wait as power supplies goes on sale often, after rebate they are even cheaper than what Amazon sells it for. So just do a search for SlickDeals and join that deal site as that is where all of these sales will popup on. This 500w 80+ Bronze powered my Lenovo ThinkServer TS140 (with the help of this connector Best Compute 24 Pin to 14 Pin ATX PSU Main Power Adapter Cable) ( https://amzn.com/B0163KB3L0 ) and powered my Gigabyte AMD R7 360 128 Bit GDDR5 2GB 2xDVI/HDMI/DP Overclocked Graphics Card (GV-R736OC-2GD REV2.0) ( https://amzn.com/B01DT48WSU ) video card just fine without any issues supply juice to the require card. This power supply is not fully modular, so extra cables that you don't need will still be attached to this power supply.

Solid quality power supply
I got this as part of a budget custom PC build I was making. After doing my research, I quickly learned that not all 500 watt power supplies are created equal. I originally was looking at a different brand "500" watt power supply only to figure out that 500 watts could mean maximum power of 500 watts, which in reality means less power than it is advertising. This is not the case in this EVGA 500 watt. This power supply provides 500 watts of continuous power, meaning it can handle a heavier load than those other "500" watt max power supplies. After seeing that this had a rebate in addition to a good price, sealed the deal for me at $39 bucks. Once getting this, you can see that it is a good quality power supply that has some good weight and feels very solid. My only complaint really is I wish that the cables were modular as there are a lot of connector cables that you may or may not use all of. In the case of this budget build, I only used a few of the cables and the rest I had to plastic tie out of the way. But it does provide enough cables and variety of cables to hook up anything you need. The power supply was easy to put into the case and connected easily and when powered up the fan is silent and works efficiently. One of the most important parts of a computer build is the power supply and for a budget build this power supply will provide all the power you need and will be reliable. EVGA backs this up with a good warranty at 3 years as well.

MORE POWER + LESS PRICE=EASY BUY
Here is my story...I was having issues with my computer. I would turn it on, the tower would work, but the screen would just lose power. It would just go blank! But why? My tower is still on and running. I called EVGA about this, because I thought it was my graphics card. He told me to check my power supply unit (PSU), and said it needed to be replaced. I was hesitant, but desperate. I purchased this product. He told me it was relatively cheap, and go for the high supply because its only like 20 bucks more. He said its an easy investment, because even if I get a new PC, I can put this baby in that. I installed this, and it worked! My monitor does not lose connection any more. My computer even runs better and much more quiet. If you need a PSU, please buy this one. If it is too much, just buy a EVGA model. The reason is that the warranty is amazing. The products work with no trouble. And their costumer service techs are beyond amazing. I call in, and they know what to do. They get me in, and get me out fast enough so I don't have to waste all day with computer stuff. Believe me, I have wasted entire days talking to techs who don't even speak English and ramble on and on. This techs speak English well and actually have attractive voices, if you like that kind of thing ;)

Quality power supply and quick access to good tech support
My wife was using the computer, heard a "pop" and the computer quit. A quick Google search revealed it was very likely that my original 350 watt power supply on my Dell XPS Studio desktop that I bought in 2010 had died. I could only hope that it didn't take my motherboard with it. I researched Power Supplies on Amazon and you can get one for as low as $19 or pay over $100. I wanted something really reliable. The reviews on EVGA constantly mentioned the 24/7 tech support. I settled on the EVGA 500 B1, 80+ BRONZE 500W Power Supply. It was $5 more than the 80+ White, and $10 more than the 450W 80+ Bronze. (Frankly, I would have bought that one, but the estimated arrival time was 2 weeks, versus overnight for this one). All three feature a 3-year warranty, quiet fan, and plenty of plugs. The 500W have even more plugs than the 450W. The Bronze series features a power supply that is 85% efficient versus 80% on the other two. All good. The new power supply did indeed arrive overnight. My dog and the power supply were both waiting for me when I got home from work. I unplugged the computer, attached my anti-static wristband, removed the old power supply, attached the new power supply, closed up the case and... nothing! Wait, what? I opened it back up, made sure all the connections were secure, and tried again. Nothing. I put in a call to EVGA Tech Support. I was talking to a tech guy within 5 minutes. We troubleshot the setup. At one point the tech said to make sure the CPU connector was attached to the motherboard. Thankfully that cord is labeled. I had connected the PCI cable to the motherboard in error. Once I corrected this bit of stupidity, the computer came back to life, my wife praised my genius (since she had her computer back within 24 hours), and my dog was oblivious. The ability to quickly access good tech support, plus the quality of the power supply, is why I am a happy camper and will recommend EVGA power supplies.

Good PSU, Would Buy Again
I've owned this PSU for a while now. It was apart of my old system and transferred to my new one. My old system had a motherboard issue and was a headache to figure out. I bought this PSU to make sure my old system didn't have a power issue. In the end it was time to build a new system, so I bought new motherboard, cpu and ram. Issues are gone now. The plug and play factor is that it worked flawlessly. The fan is barely noticeable compared to my case fans. You would have to look at the fan to see that it's spinning to know that it is working. At the time of purchase the price was good for the watt rating and the 80+ Bronze efficiency. I can overclock on my new system without worrying about power delivery. The only thing I have to worry about is if I wanted to run Crossfire or SLI. I have to make sure the gpu cards I choose and total system power draw all fit within the 500w limit or I'll have to upgrade. Other then that I should be good This doesn't RGB lights or anything, so if your hoping for that look at a different one. It's more like a stealth look, all blacked out. You might forget it's there if you have an all black case and remove the decals. Only con is that it's not a 80+ titanium. Just kidding lol

First time replacing anything in my computer, works amazingly
For context, I'm a 20 year old woman who has absolutely zero experience working with the actual hardware of a computer. This is the very first computer part I have bought and installed on my own. It was one of the easiest things I've done in my life. I bought it as a replacement for a 350w power supply that has been underpowering my computer (a GUA1000BST) for the past year and was beginning to die. I did reference a few Youtube tutorials for basic information, but I didn't even need them while I was actually installing the PSU itself. It was extremely straightforward. Since installing this, I've had no computer issues. I was dealing with random reboots and shutdowns, and I was getting BSODs from, allegedly, my GPU almost twice a day for the past few months. This seems to have corrected the issue entirely. My computer also used to be extremely loud when running and this has basically silenced it. So far everything is running perfectly and I feel a lot more confident upgrading my system in the future! This is a good unit, installation is straightforward, and if you need the extra help there are plenty of resources out there.
