Hi everyone,
I have a very high end, brand new performance/gaming rig I use for work and gaming. Most of my rig I replaced this year but one thing I have dragged on from build to build is this Thermaltake TR2 600W PSU:
http://www.amazon.com/Thermaltake-Power-Supply-240-Pin-W0388RU/dp/B002RWJGHM/ref=sr_1_5?s=pc&srs=2530613011&ie=UTF8&qid=1368681344&sr=1-5&keywords=thermaltake+tr2

When I originally bought this PSU along time ago, I didn't know what I was really doing and just rushed and bought something. Now recently I started noticing on maximum load my PSU is using over the 600W limit of this power supply. I am getting random shut downs/reboots and have routed it down to my PSU. Not only that, but it is noisy at times and made my electric bill go up. Overall this just isn't a quality PSU for my expensive, water cooled rig.

I have educated myself on PSU's through this site and others and I would like to get something that is going to last a long time, save energy costs, and have lots of power to run my demanding rig. I have been eyeballing this PSU for the past week and I really like what I see (the Corsair HX750):

Bottom line - I love the stats on it. Do you guys recommend this HX750 model or should I get something cheaper or a different brand? Is is worth the extra cost? But how much more "efficient" would it be than say, the CX750? The CX750 is almost $50 cheaper and I really don't if the cables are modular or not. There's a CX, TX, and HX models. The HX just seems to be the biggest jump. For that extra cash you get a gold rated, high quality PSU it seems.

I'm also hell bent on the Corsair. It just seems like a sexy PSU. Does anyone recommend anything better for the price than the Corsair? I just hear Corsair is among the best for PSUs and I own a Corsair Force SSD and I absolutely love it and never had problems with it.

1. The Thermaltake TR2 is a good brand. I trust it myself.

2. The Corsair CX models were built for basic systems, not high performance systems. So since you are using it for gaming, that would qualify as a high performance build.

3. The Corsair TX models have the best performance/price ratio0. I recommend it.

4. The Corsair HX models are really middle ground between TX and AX. They're semi-modular, which is good. But they are expensive. They are priced almost as much as the AX models, so get the AX models if you really are going for it.

5. Saving energy costs between a Bronze and Gold efficient PSU is negligible. I honestly wouldn't worry about it. On average, a Gold certified PSU is about $50 more than its Bronze counterpart...

That's not true in all cases of course. Anyway, if you leave it running 24/7 for a month (like a server), you would probably save anywhere between $0.50 to $2.00 between the Bronze and Gold. How much you save is dependent upon how much you use it and at what load. But at $2.00 a month, it'll take you 25 months or over two years to replace the cost of the Gold PSU over the Bronze PSU.

6. Antec (Earthwatts, HCG, HCP), Cooler Master (Silent Pro), Enermax (Platimax, Revo87), NZXT (Hale90), PC Power & Cooling (Silencer, Silencer MKIII), Rosewill (Capstone, Hive), Seasonic (all), Super Flower (Golden), Thermaltake (Toughpower, TR2), and XFX (all) are all great PSU brands.

Hi - 1st thing is, your system can run fine on a quality 550w unit. Your problems are
most likely due to the fact that most TR2's are not good PSU's, the one you
have is an HEC built unit. HEC is pretty much a bottom dwelling OEM.

The Corsair hx750 is more than you need, but there is no harm in it
except for the initial cost. There isn't a review of it from any of the
top 3-4 PSU review sites, it is made by Channel Well Tech and is most
likely a well made unit. I wouldn't hesitate if I were you.

There's good TR2's and there's bad TR2's I don't know why they have 3 different kinds but they do. Corsiar HX is either the top of their line or second to top (under the AX). There's nothing wrong with Corsair units but they are a lot more money than other units and you don't really get anything extra from them. If it's a gaming rig, sure go for a 750w, it'll handle any two card setup and if your buying a big PSU you'll have forever you should get an 80+ gold rating (I kind of wish I did). Some cheaper ones you can look at:

Thanks for the responses. I have to agree a quality 600w PSU should run my system, the TR2 is a really clunky power supply. There are a number of minor "anomalies" I get that I can point to it being a cheap power supply. And for what I paid for it I really got ripped off by Best Buy, I wish I researched better back then. I definitely want to replace it, but the question is with what?!

I've pretty much got my mind made up on the HX750 on Amazon. It's $114 right now. It's definitely more than I want to spend on a dumb power supply but I don't think I'm gonna get any better for that price. 80 plus gold rated, modular, 7 year warranty, it will probably last me a very long time and that's all I want is to not have to buy another PSU for along time!

I was about to click the "buy now" button but I held off. I just hate parting with my money on a boring power supply. 🙁 But it's a good investment. I put alot of money into this rig and don't want to ruin any of it with this crappy Thermaltake PSU any longer.

Done! Ordered the HX750, should arrive Saturday. I'll come back once it's installed and post some initial thoughts/first time use comments. I actually can't wait, it's been a while since I've done some serious PC building! And I really need to do some rewiring in the back of the case anyway, it's a nightmare of twisty ties and madness.

I also picked up a two pack of the Corsair SP120 high performance 120mm fans for my radiator. It's been six monthes now with this XSPC cooling ckit, besides the three stock 1600rpm fans it came with I have an antec fan on top. These fans don't quiet get the job done despite me liking their quietness so I got something a little more potent!

Sorry for bring such an old post up... BUT, how did the HX750 turn out? I'm debating between this and the Cooler Master V700 which has been given damn good reviews, and great reviews on newegg (discounting the ones of DOA).

I've seen a lot of posts of a loud HX750.

Hey pal, no problem resurrecting this topic, I love talking computers! It's hard to believe I bought this thing half a year ago already!

You know what, I highly, HIGHLY recommend the HX750. It is an absolutely wonderful power supply. I have had no issues whatsoever with it since I bought it. Comes with plenty of cables to hook everything up with. And it is the completely opposite of noisy. This thing barely makes any noise at all, in fact to be honest, I've never heard it running at all. It also doesn't run the fan at all during idle/low power usage, only when I do extreme gaming does it ever run. And it stays very cool when it does, barely warm to the touch.

I can't say enough good things about the power supply. It also lowered my electrical usage ever so slightly with my powerhouse desktop as it's gold rated. I was very reluctant to drop $120 on a power supply but it was worth it, easily the most stable/reliable piece of hardware in my PC now. Not to mention, I think it comes with a seven year warranty which is awesome. Six months in, no issues here.

It looks like that Cooler Master V700 is a direct competitor/solution towards Corsair. I'm not sure about that Corsair, I'm sure it's also a top-tier PSU. But I am beyond satisfied with the HX750.

I'm going to have to respectfully disagree about the Cooler Master model being better than the HX750. In fact, that's a pretty bold statement to make unless you've personally used and stress tested each one. As far as the HX goes, well, I owned it six months now and I love it. I've owned cheaper PSU's in the past and this thing absolutely blows them out of the water. The HX750 is a top quality power supply, if not one of the best on the market for it's price range. Mind you, I'm not only using this as a gaming rig but something for professional work in programming, design, and rendering.

I see your comments about CWT and Corsair not making the product. To be honest, I see people say that (even when I researched into buying mine) yet I never see any clear evidence to back that statement up.Where is this information about manufacturers????? It's not on the box and it's not the the label of my power supply. I've even accessed their website. I don't see anything about manufacturer's.

But furthermore and more importantly, what does it even matter? What or who is to say CWT isn't just as good? I'm sure if you dug deep enough, you would find just as much dirt on Seasonic. The bottom line, I really don't think the manufacturer matters (if there is even some backing to that statement). What matters is these are both top brand power supplies. I think EITHER of them would do great. I just have to respectfully disagree that one is better than the other because of some unproven and untested statements about hte manufacturers.
