    Decent Psu for a small system but for 5-10 dollars more a 600w is much better

    I bought this on sale because I used an EGVA PSU in another system I just built with no problems. However, this particular model has turned out very bad. I returned one that was bad right out of the box. I got a new one (same model) upon return only to have that too dead right out of the box. This has held up my PC build two weeks. I guess you get what you pay for. I would not buy one again. I will return the second bad one and see what happens with the third. Both these bad units were tested both in the PC hooked up and also out of the system and neither worked. I am not happy.

    I purchased this power supply to put into a Christmas gift for a family member. Assembled the computer, and got nothing except for coil whine. I tried quite a few different things, but ultimately nothing worked. Will be returning and getting my money back to buy something that actually works!

    Doesn't work! I wish I would've listened to other reviews about this thing. I just got it and it doesn't work at all. So have to find out how to return it now and get something else.

    I got a faulty product, I know it’s not Best Buy’s fault, the product was brand new but it didn’t turn on or power my motherboard at all, I would recommend EVGA Bronze power supply

    Randomly pops and makes my room smell like burnt wires. If you grab this PSU make sure you dont leave your computer on overnight or while out of the house. Otherwise it works wonderfully if you overlook the fire risk.

    Installed this in my computer and it worked fine for 19 days, then it failed. Took it back to Best Buy and Manager refunded my money without any problem. I did buy a new computer while I was there.

    After two motherboards mysteriously dying, tester says power supply is no good. Didn’t think I had to test one new out of the box. Lesson learned.

    It didn't work :(, and parts were missing in the box. For the price it has there are better options like Seasonic or the same Evga but in different models :(

    I've purchased two of these now, two different builds for budget gaming rigs. No issues so far, noise levels are near zero and works great with Nvidia 1660 super and AMD 5500xt 8 pin graphics cards.
