      Fixed my PC starting problem

      • My Best Buy® MemberMember

      I started having start-up problems on my Dell PC about three months ago. At first, I would open up the case and reset all the component plugs to the motherboard. That worked for a while. Then I tried resetting the RAM. That also worked a time or two. Finally last week, no matter what I did, the PC wouldn't power on. The PSU would light up and the motherboard would light up but absolutely no power other than that. I did some research online and found a few other people with my PC model with the same problem. Some said they replaced the PSU and that fixed the problem. Others said they had to replace the motherboard. I decided to try replacing the PSU first. I bought this unit (the Thermaltake 430w TR2 ATX Power Supply#. Installing it was easy; it fit my Dell computer case perfectly. Once it was installed and all hooked up, I plugged it in, pressed the power switch, and it instantly started! The fan runs quiet and I think it is doing a better job of keeping my computer case cooler. As a bonus, I now have 70w more power should I need it. The only drawback is the short distance between component power plugs. It would be nice if they were spaced a little bit farther apart. I understand that you don't want longer cables taking up all the tight space inside a computer, but a little more distance between plugs would be nice. I was able to work around the problem though. This unit came with five SATA plugs and I only needed three, so I was able to skip a plug and use one further down the cable. I also don't have a PCIe card that needs power from the PSU. If I did, making the cable reach from a SATA component to the PCIe in the back of the computer would be very difficult if not impossible. And I have a mini-tower. Still, all-in-all, this PSU is thus far working very well for me and I consider it to be a good deal and a high-quality product. #Did I mention that it comes with a 5-year warranty?)

      Really Thermaltake, REALLY??

      • My Best Buy Premier Silver MemberElite Plus Member

      I could go on and on, but I'm going to keep this short. Pros - Runs smooth and easily puts out reliable power - Easy to install - Cool looking - Cords are wrapped for better airflow Cons - ONLY 2 Sata connectors on the same cord! Worse yet, the connectors are only separated by about 4 inches. Soooo if you hook up your CD and what to hook up something else like....ohhh i dunno...a HARD DRIVE, then forget it. It's not happening. Conclusion I would not buy this PSU again. Despite being a reliable PSU, I really expect better from Thermaltake. I don't know who came up with the bright idea of only putting 2 Sata connectors on the same cord (making it almost effectively 1 sata connector really since the connectors are so close), but I'm seriously disappointed. I suppose I *COULD* order some molex to Sata adaptors for the 15 bijillion molex connectors that Thermaltake put on this PSU, but should I REALLY be forced to do this just to run both my CD and HDD? Thermaltake seriously needs to rethink their design here. They would have a rock solid PSU at an affordable price here if they simply changed 2 molex to Sata.

      Old tech connections


      Problem: I've got a three-year-old computer that needed a new power supply. This was the only one the the local Best Buy had on the shelf so I bought it. I've got a dvd drive and two hard drives and they all take sata connections. So the first problem is that this thing only has two sata connectors with a very short section of wire between them. First thought is, "I can connect the two hard drives." Guess again - the wire between the connectors is so short that I couldn't connect two hard drives that were side-by-side. Solution: I've ordered a 4-pin to 5-pin sata conversion/splitter that I will connect to one of the otherwise useless 4-pin connectors. When it comes in I'll be able to connect all three of my sata devices. Until then I'm only powering the main hard drive. Other than that, it fit just fine in my Dell and worked right the first time. I like the power switch on the back, the original didn't have one.

      Great! Cords a bit wonky but works like a charm!


      So I put it together. Plugged it in and the computer whirred to life! Then died... Oh no... I got a DOA... I went back, opened her up again and my dumb self realized "You didn't even plug in the CPU connector properly!" So I do that and while I'm putting all the screws back in place I find a notice that says " WARNING: Use correct AC switch, failure to do so will cause permanent damage and void your warranty!" I remembered tampering with the volt switch. So I quickly ran over to plug it back in the the wall and plug everything back in. To my relief it whirred to life and stayed that way... phew. Anyways... I'm using it to type this review and it's whisper quiet. I had concerns about noise when I first turned it on but after 5 minutes it went away. Happy with my purchase, great value! I just need to make sure now that it stays relatively quiet while playing those high end games I bought for the PSU to power GPU for.

      Good HONEST Review of TT TR2 430w PSU


      This is a new version of this power supply. The older version had a single 12v rail of 18 amps and only put out 350 watts according to professional reviews on the internet. This newer version has TWO 12 volt rails. One has 15 amps and the other 14 amps. This version is also heavier than the older version though it uses the same box and dual 80mm fans (I do have the older version for comparison). Now I don't have thousands of dollars worth of PSU test equipment or lie and read on line reviews and say I test the output of this newer version of the tr2 430w power supply. I do know that this one runs quieter and runs my quad core computer with a mid range video card quiet well with all voltage rails very stable under load using a multi meter to verify. Thermaltake even offers a 5 year warranty on it. It is not a high end PSU by any means, but it will deliver solid power to a moderate pc and is an improvement over it's predecessor.

      Good for the Price


      Actually fit my application nicely (Dell Dimension 9100). The mounting holes even lined up but there is a slight gap underneath the supply, but I can deal with it. There are lots of 4-pin molex connectors and the close/short wire lengths resulted in nice and neat wiring for my optical drives that were stacked on top of each other. However, my SATA hard drives are mounted horizontally on the bottom of the case, and the 2 SATA connectors were daisy-chained too short to reach both drives. However, a cheap $5 SATA extension will solve that problem easily. Note: my computer is used as a server so I don't need a lot of horsepower/quality, just something that works. Also, the second (currently un-powered hard drive) is a backup drive, so I can live without it until I get the extension. Lots of connectors and fit my application nicely. Although cheap in price, it seems well put together.

      Good upgrade for those lousy stock PSUs


      I purchased this to upgrade from a stock 250w PSU in my PC. I don' t understand why PC Manufacturers can't just shell out an extra $20 and have a decent watted PSU come stock with the machine. Good price and was easy to install. Please note that the SATA connectors are a little weak. I ended up breaking one when simply trying to connect it. Specs are good for the price. Not a bad little PSU just handle with care. Make sure you have enough connections available or you might not to get an adapter. I was able to take a two SATA adapters from the stock PSU off of my new HP and used them in connecting optical drives and hard drives. I am running a GT430 video graphics card off of it and it runs fine.

      Excellent PS for older systems and newer

      • Verified PurchaserVerified Purchase
      • My Best Buy® MemberMember

      Older PS burned out suddenly and need quick replacement for older system, but didn't want to break the bank since I just use this particular desktop system for misc. projects. Went window shopping at Best Buy and found this unit on sale for $39.99 and it had all the molex connectors I needed to attach to the older devices I have installed. Seems to be getting harder to find enough connectors on PS units without having to adapt the SATA style connectors. More than enough power to run the P4 system it's installed into, with plenty of SATA connectors to use for future upgrades. Plenty of cable length on power lines to reach devices. Runs quiet and fits standard tower case without issue. Have been running it on and off for about a month now and no issues. Would recommend this brand without question. Great deal even if it wasn't on sale.
