    Yes, that PSU is pretty good & will power a decent mid range system without breaking a sweat.

    To be fair the 7300GT is only slightly better.

    If I were you, I would save up about $100 & buy a mid range card - i know it may take a while - but it will be worth it in the end. Spending $60 on a low preforming card is wasting your money because the card wont play decent games to begin with.

    No, don't buy it. IT's only got 18a on a single rail, crossloads terribly, quality is spotty, and it's just not worth it.

    Pony up another 10 bucks and buy the XClio Greatpower 470, I think it is. Much more power, quality, quiet, and around 50 bucks.

    18 amps should be enough for a amd athlon 64 x2 3800+ EE
    3 hard drives, 1 cd-rw drive.
    My 15 amp psu can do it fine.
    A 7300gt requires 18+ amps.
    also XClio Greatpower 470 is to much.
    also the most advanced game i'm playing is Aoe 3.

    it Should be enough, and it is, but there's more than that; Would you ever drive your car at max speed for hours at a time? Same thing with a psu. Sure, it works at max power, but it's better to not load it up to full load continuously. Not only that, but it's the quality issue once again. "It worked for me for a while so it's good enough" is not a good argument. 99% of custom built pc's use deer, powmax, or other generic psu's. It works for them most of the time too. I've personally had a deer in a pc that worked perfectly for 5 years. No problems at all. Then it took a **** and killed a board, cpu, ram, video card, hard drive, and dvd drive.

    Your power bill also will be lower with the XClio: It has higher efficiency. Your psu only draws what you need. You can have a 200w psu, or a 1000w psu, and if your load is 150w, then it will only draw 150w.

    Depends which one. CWT built ones, I don't suggest because of the use of Fuhjyyu capacitors and the silent fan control (leading to premature death). FSP/Seasonic/enhance built ones are pretty good.

    CWT: Smartpower, Smartpower 2.0, Truepower, Truepower2.0, Phantom, Neopower
    FSP: Basiq
    Seasonic: NeoHE, Truepower Trio, earthwatts
    Enhance: Truepower Quattro

    i guess i'll go with a corsair.
    Because the XCilco has weak amps on the 2 12volt rail.

    If you can afford it, buy a Corsair PSU - they are very good.

    I personally use Tagan, they are also high end with very good build quality.

    Next I would say Hiper, then theres many many good quality PSUs like XClio, SilverStone, Antec etc.

    And just to prove that the Thermaltake isnt such a bad PSU, here are some reviews:

    also with rails, do you combine th 2 12v rails to get the total amp or what?

    no, a PSU is rated by its total amperage on its +3.3v, +12v, +5v, -12v, -5v & +5vsb.
    If a +12v rail has an amperage of 28A its gives a total of 336W (V*A=W) It doesnt matter how many molex connectors or leads the PSU has it can only supply the maximum rating for that voltage.

    I really dont know why your so concerned about this PSU for your system - any 'half decent' PSU will run your rig (400W will do it)

    (nb. 'half decent' is not the same as cheapo!!! )

    So one that says 1v12=18 2v12=16 they would equal 34 amps total, right?

    Yeah, but you cant combine the rails to feed one piece of hardware - Unless the PSU supports this feature, like this Tagan. Usually, most PSUs only have one 12v rail (the independent wires feed from the rail). Newer and more expensive PSUs come with indepentdent 12v rails, some as many as 4 clicky here - have you got a link to the PSU you mean?

    Generally, you kinda get what you pay for. It'd prolly be okay, but I'm one to walk softly and carry a better PSU. Would I buy it? No. I'd go for the Corsair.

    rito - for your system - & if your on a budget - that PSU will be fine.

    E.E.L - for your system, no way - you would want a high quality PSU to match your system - hence thats why your using a Corsair PSU.

    True, but I guess I'm also looking at reliability in the long-run. Maybe I'm just a PSU snob :hehe:.

    The thermaltake Is such a bad psu; The first review (Hardware secrets) does not even load it up. It just disects it and gives it a good mark. It doesn't have apfc, good efficiency, enough amperage, cheaps out on a lot of things to make it cheap, and does not crossload properly. Find me a review that uses a load tester and not a system, and pushes it to the brink of destruction, in the style of [H] and JonnyGURU.
    The second link, Amazon? "I put it in my pc it turned on 5/5" reviews all over. Not exactly valid, considering that most systems won't draw enough power to push the psu.

    No. Find the total combined wattage for the 12v rails, and then divide. For example, if a psu has 2 18a 12v rails, with a combined wattage rating of 348w, then just divide 348 by 12; you'll get the figure of 29a. You can load it on whichever connector you want, as many connectors as you want, and each rail will load up to 18a, but not at the same time.

    Sort of. Any "Half Decent" psu with enough wattage will run it. And by Half Decent, I mean something that's high quality.

    Nope, see above. The XClio doesn't publish the combined wattage ratings, but I do know that the psu in question has a max output of 29a.

    Even if the psu supports rail splitting / recombining, it most likely won't be the combined amperage. Newer and more expensive psu's usually come with Single rails now, which is how it should have been the entire time. Multi rail, if you have minimum load on one rail and you exceed the load of the second rail, the psu ocp will kick in and it will shut down like it's supposed to. So in the case of the XClio, if he loads it with 2a on the first rail (a low wattage cpu, the cpu always has it's own rail) and 17a on the second rail (say, 2 8800gtx's), it will shut down, even though it's not even close to max load.

    It's an enhance based psu. It's definatly quality. Not as good as the corsair, but definatly not as expensive.

    I have a similar one pushing an E4300, 7800gt, and 6 hdd's. It only draws 168w from the wall. There is no problem, and there will never be one. Every actual test (load tester, ripple, transient, crossloads, pushing it to the brink of destruction) of enhance based psu's < 600w is favorable.

    You think You're a psu snob.. :brrr:

    I'll just go and get a corsair.

    :confused: Actually, I know I'm a PSU snob. Before this current rig I was running a PCP&C unit. Before that a Tagan. And before that it was another PCP&C unit. Two of the three of those are still running strong 24/7 to this day. I like quality merchandise; mostly higher-efficiency ones. :)
