    Corsair +3

    Edit: I felt like I should give a reason for agreeing on Corsair.....both are great PSU's but the Corsair will put out around 780w in all reality, the OCZ wont do that but is still a solid choice.....you wont go wrong with either, but if you can throw another $25 at the Corsair it will be a better investment. :)

    Even owning a Game Extreme 700 or two, Id opt for the Corsair as well.

    Another vote for Corsair! Top PSU manufacturer, had no probs with mine what-so-ever.

    I'm actually going to go against popular opinion, and say the OCZ but only if you can get the same type with 650 or more watts. The reason: The Corsair only has One 12 volt rail. The OCZ has 4 meaning there's more balanced distribution of power drain. and is better if you use of high end videocards that require the power connectors be on separate rails.

    the 3 most reliable and powerful(for thier wattage rating) power supplies available today-Seasonic, PC power and cooling, and Corsair. Corsair and PC power and cooling PSU's are made by Seasonic.

    He got it right on!

    With seperate rails, you risk overload one... especially with higher end cards... Also, I dunno but I've always been thought that 1 rail >>>> 2+ rails

    I would spend the extra money to get the 750TX if you can... it'll leave you with A LOT of headroom... This is absolutely not necessary though, just something that would be good if you ever get a GTX 295 or if future rigs will consume a lot of energy xD

    Corsair, HOWEVER, if the opposition was the GameXstream rather than the StealthXtreme I would have gone for that as it's a Tier 2 PSU but as it's not, I wont! :ohwell: I hope you know what I mean cause I havent got a clue!

    Actually you're wrong manufacturers have gone to single rails, because they are better. Most PSUs that advertise 4 rails actually have two split rails.

    i have a gamextreme 600w and like it just fine, i dont think youd be wrong to go with ocz. if the MIR wasnt there on both then id say get the ocz becuase of the significanty price difference, but after the rebate, $10 for the corsair would be worth it.

    yes but not all their PSU line is built by them. The Game Extremems I bought were before the purchase of PCP&c and I was lead to believe thet the GSX700 was an FSP.

    In my OCZ PSU even with the PSU being labeled as a multi rail, IIRC 3 0r 4 18A rails. They all terminate in the same spot on the PCB and are all soldered together. So distribution is nil, it just sends the power and the rails absorb what they can use.

    Not all PSU's that Corsair sells are made by Seasonic. Some are made by CWT (like the TX750W) and they have other OEM's also. But in the case of the TX650W the manufacturer is indeed Seasonic, even if it's one of their slightly older models.

    The TX650W would be the better choice. Extremely stable rails, little to moderate ripple noise (moderate ripple noise on the +12V rail near and at full load). At tipical 50-75% load it's almost perfect.

    Oh wow. No wonder my TX750 makes a buzzing sound even while off. I might go return it tomorrow.

    No, the TX750W is not an inferior product. It is based on a CWT design, it is manufactured by CWT, but it uses components that are specified by Corsair, like better capacitors (105C), higher spec'ed power transistors etc. (It can reach more then 900W load before going out of ATX spec). It even has a mono-rail design (compared to the classic virtual multi-rail CWT design). It has four 6+2 pin pcie power connectors. Stable voltages. Ripple noise is comparable to the TX650.

    I have the TX750. Works fine. Quiet. But if you need to have 2 video cards in CF/SLI and they need 2 sets of 6/8 pin pcie power plugs then you can't use the TX650 out of the box, it only has 2 6+2 pin pcie power connectors (you can use adapters, but they make your cable management look messy).

    The thread is about the TX650 and some other PSU. I was just saying that the TX650 would be the better choice.
