Thermaltake Smart 500W 80+ White Certified PSU, Continuous Power with 120mm Ultra Quiet Cooling Fan, ATX 12V V2.3/EPS 12V Active PFC Power Supply PS-SPD-0500NPCWUS-W

Our old power supply failed, so we shopped and selected this one to replace it. It was a great purchase! The old one was only about 250w, and obviously this one is rated double at 500w, so happy for the price that the new one isn't working as hard to run the system. It also has large fans and lots of cooling vents, but what shocked me was how quiet is was while running. Installation was straightforward of course, all these are basically universal and 4 screws and unplug / replug and it's installed. I'd call this a reliable replacement PSU without breaking the bank. Our PC is back up and running perfectly!

This is a moderate power supply, and non-modular, but it is very inexpensive for what you get. I was building a lower end gaming rig. Nothing like the newest GPU, not the latest and greatest CPU. But, the case needed a power supply. I didn't want to buy anything fancy, so I spung for a brand I have used before and I got this. Install was simple it fit the existing slot just perfect, screws line up as expected. It had more than enough power cables for all my needs, and adapters that I didn't need incase I add hard drives or other things in the future. It is quiet, I can't hear the fan running. It runs flawlessly, at least I have no reason to think it doesn't. It is one of those things you don't notice when they are working properly, and I don't notice this at all. It just works. And for the price, it is a deal.

I been a computer tech for a long time and it's hard to beat Thermaltake products. You will notice that they are a bit heavier than some of the cheaper brands. That's due to the fact that they're made from good electrical components. They just seem to last and last. They will fit right in all of your standard computer cases. They are slightly more expensive but you are getting a lot of value for what you pay. They are easy to install and the cables are well organized for being able to connect to components. I highly recommend these power supplies.

This power supply works very well in an old Dell XPS Studio 8100. Great price. I have shared a screenshot of the voltages after installing the Thermaltake power supply. It is very well calibraated and close to target voltages. My only criticism is that it has every conceivable connector type, requiring a large desktop case to stow away unused connectors and cabling. It is unlikely someone will need the 4-pin accessory connector and it takes up a lot of space.

I was about to jump on here and blast the company and this product because after I installed the PSU and powered it up, my PC would do a hard shut off within 5 minutes. So I went back, checked the PSU connections, made sure everything was tight. Turned PC back on, same thing. Was about to rip it out...when I noticed...my CPU fan wasn't plugged in and must've come out as I was installing the PSU. PC wasn't shutting off because of the PSU, but because the processor was overheating! Luckily, nothing was fried, I plugged the fan back in and everything was great. But I wonder how often something like that happens to people when installing a PSU, and they blame the PSU for frying their board? Anyway so far this PSU is running great and it's super quiet. When I built my PC in 2008, the case came with a cheap Rosewill 350 watt PSU, and that's what I've been using ever since. The thing has been on pretty much 24/7 since 2008. underrated brand to say the least. Within the past few weeks it started to really shows its age though...PC was becoming more and more sluggish, lag in old FPS games was getting worse and worse, I couldn't connect anymore than 1 sata drive or it would short out, etc. Since installing this Thermaltake PSU my PC is definitely back to running super smooth again! Hopefully it lasts a long time, but so far so good. Great purchase.
