Customer Ratings & Reviews

I needed a PSU upgrade for my 1070. This does the job.

good quality for the price does the job no problems as of yet.

I needed something with more wattage...but its loud.

easy replacement and very low noise just as indicated

Great power supply with a very fair price. Easy to install.

Very Good steady power so the computer runs smoothly.

This was my second replacement to handle power needs of new graphics card. Best buy recommended the upgrade, first one lasted less than a year... lets hope this one does better

Purchased at.store. Not a lot of selections. Needed one right away to repair sons computer. Bedt I could do for an out of the way area. Just ok for the price.

Not the best power supply I've ever purchased but it'll do on short notice. No bells, no whistles, no modular support, just a power supply

Didn't fix the problem, but don't know if the issue is with the power supply or another computer component.

I had already changed out for a better power supply.

A little overpriced in comparsion to other power supplies available on line.

This is only based on the fact that it would not work for my computer.

After purchasing the 520W ATX Power Supply it worked two to three weeks then it just stopped. I was told that I had two weeks to exchange it my work schedule would not aloud me the time to go back to Best Buy to exchange it. I have a dead computer...

It works but it's noisy. I bought it at a local store for emergency use only while I was waiting for my order for a Corsair PSU from another famous online seller.

I have to say I am very unhappy with the recent service call which replaced the power system only to have the computer break down again a month later. Last year we replaced the hard drive for the second time. This computer has been a problem since day one. I would never buy another product from Best Buy.

Read the directions as this isnt a true 520 Watt unless the all plugs are used. Make sure you read the back to get the details I think it said somewhere in 470 if I didnt use all the plus.

I bought this power supply and it was faulty. I had to return it and order in a different power supply. Lots of hassle. Save yourself the trouble and order an on-brand power supply.

This powersupply is very nice. I know quite a bit about power supplies and this one is alright. The fan is very quiet and is effective. It peak power is 520w, but it's actual continuous power is 420w, as it states in the manual. It matches my grey metal case, so it looks very uniform. It is a little long, so the cables were touching the optical drive. The 20+4 pin was a pain to get into the motherboard because the +4 pin wasn't staying attached to the main 20pin. But i used 2 hands and it got it in alright. It is being used to power my HTPC, which Is a custom build, which had a 2.2ghz athlon 64x2 (110watts) 3gb ram, 500gb hdd dvd drive and an AMD radeon 6450 (over clocked to 750 mhz core and 560 mhz memory). The powersupply is quiet enough for a htpc. The fan kicks up nice and loud when it is first powered on just so you know it works.

Needed a cheap temporary PS until a replacement came in for my previous PS which is in the RMA process. Got in on clearance for less than $30. So far, no problems. Running 24/7 for over a week now, without issues. Enough connectors and power for a mid-level PC (8 pin ATX and 8 pin for graphics card, and a couple SATA plus a couple Molex). Running an I7-4790K, 32GB ram, 2x SSD, plenty of fans, DVD and RX 480 just fine. Only con is no On/Off switch. I've been saved from frying a system a few times just by having that. As a temporary replacement, it's working just fine. Should work great for a system with less load as a main PS.
