Is my PSU enough?

    Hi guys, just came into a bit of a realisation recently after a mate of mine talked about his problems with his PSU.

    My current set of hardware, I'm using a Corsair TX-650W. I'm about to add this "XSPC X2O 750 Dual Bay Reservoir and Pump V4".

    Would a pump use that much juice and is my PSU even enough to run my hardware (and possibly overclock it)?

    I ask this because the problem my friend had is that his computer would blackscreen from time to time and say that the graphic drivers have had a fatal error. He's formatted the PC and installed the latest drivers and it still happens (faulty PSU, he had a 900W gaming one, don't recall the brand).

    I had this same issue for a while until a Windows 7 update solved the crashes (a previous friend had said that maybe my PSU wasn't putting out enough power to the 12volt rails).

    It should be enough. The highest draw will be from the GTX 570 at about 300W. That should leave you with plenty of headroom for the cpu and other components.

    More than enough for any single GPU setup.

    Thanks guys. I figured as much, I got a fair few opinions from people about the build I made and they all said the PSU would be good enough even for the 670.

    The only reason I asked is due to the problem I had where the GPU driver kept having a fatal error at random moments. Seems that an update that Win 7 did fixed it so I'll just chalk it up to a software issue.

    You should be fine and coming from a gtx 570 you'll be be fine even with a gtx 690 nevermind single gpu cards.

    The GTX570 draws at most 180W-200W under heavy load gaming. I think only running Furmark will get you higher but that's something you don't do usually.

    The GTX670 uses less power, you should see 150W under heavy load gaming. TX650 is a very good PSU so you'll have no problems. Driver crashing might be related to different things, the game itself, unstable overclock on the card.

    I was getting my numbers from the TPU review here: http://www.techpowerup.com/reviews/ASUS/GeForce_GTX_570_Direct_Cu_II/21.html

    264W is quoted as the maximum and i added another 10% to take into account the overclock on it.

    I agree that it will rarely use that amount and never for extended periods. However, i wouldn't be surprised if it were to spike there every now and then.

    thanks for the advice guys. I'm probably going to upgrade to the GTX670 sometime next month if I get my xmas bonus. :p

    The "maximum" is the absolute maximum power the PCB that deliver. It's NOT the load value the card pulls under regular conditions. That card won't exceed 150-175W at average. Not even for once. The "spike" you're talking about is called the "peak". Not "maximum". Peak power consumption and MAX power consumption are two entirely different things. People tend to overestimate BIG TIME since they don't understand these things.

    I'm just going by what it says in the review:

    "Maximum: Furmark Stability Test at 1280x1024, 0xAA. This results in a very high non-game power consumption that can typically be reached only with stress testing applications. Card left running stress test until power draw converged to a stable value"

    The peak value is still 181W, non-overclocked. So somewhere around 200W for an overclocked model.

    Maybe my first post wasn't as clear as it could have been, but i was just trying to point out that even at a maximum of 300W he still has plenty of headroom.

    Personally, i would want a psu that would be able to deliver on the maximum load the card could (theoretically) put on my system.

    Look, do you comprehend what you post? Let me see.

    "Maximum: Furmark Stability Test at 1280x1024, 0xAA. This results in a very high non-game power consumption that can typically be reached only with stress testing applications."

    So what do we get here? We get that it's a THEORETICAL value you'll NEVER under normal considitions pull. So it does NOT matter.

    And here's why the "maximum" value further doesn't matter. If you go by the MAX value alone, you need a 2400W PSU for 580 Quad, whereas that setup only needs 1200W in reality, which is why you should NOT care about the "max" value and just look at average instead.

    Not a hard question. The answer is yes. No need to split hairs

    OP,,,That IS a great PSU, corsair is VERY reliable , ALL products electronic, and non have s few lemon's. But as far as electronice go, corsair seems to keep that number of "lemons" VERY low. I run a CX 600 corsair, and I have it running a:

    H2O corsair H-70
    i5 2500k @ 4.0Ghz
    WD 250Gb Cav Blue
    Samsung 250Gb
    LG optical Drive
    16Gb Kingston Ram
    Asrock Extreme 3 Gen 3 MoBo
    6 (six) 120mm scythe 130CFM case Fans
    powercolor HD 6950
    GTX 9800 for Physx
    usb 3.0 seagate flex go 80Gb drive
    Madcatz xBox 360 controller
    And it Runs Smooth as can be @ over a year old , 24/7 365

    If I remember correctly if Draws AROUND 475Watts with this setup. Not totally sure though , but it's fine .

    Sleep easy fellow PC'er It'll hold up just fine, but it's good that you checked, a lesser PSU @ that rating might not run so well in the same circumstances.

    Happy Holiday's to All.

    You obviously need to take more care in your reading. I already said that it was the THEORETICAL maximum.

    Whether it matters or not is up to the individual user. It matters to me as i like to stress test my GPUs when i overclock them. I have to look at what my psu can push if i want to do this. personally, i would not be comfortable running a system where a benchmark could (theoretically) blow my PSU.

    His PSU is enough for his system whatever and i have never said otherwise so this whole thing is moot.

    The point here is that your point is just pointless because it's "theoretical". You can save your doh...

    It matters to you because you don't understand PSU design or know what a protection board is.

    If you want to guess how much an OC is going to add up, add up an extra 50W or so and leave it at that. No benchmark could blow your PSU as long as you know what you're doing. Even if you don't, the changes of your PSU blowing up is as high as me being Bruce Dickenson... because, any decent PSU has overpower protection to protect the PSU in case of an overload.

    It's only the majority like you, who don't understand these things that overestimate. It's the FUD that gets thrown across is the reason why people overestimate power figures. It happens every time a PSU thread gets opened. Now if you would think a bit, you'd understand why it gets on the nerves of people who took the time to learn these things.

    You don't actually seem to have any idea what my point was. However my point is pointy enough that i have never had any complaints of the pointiness of my point.

    Let me spell it out for you as you clearly have issues..

    The maximum draw that the 570 could, would or ever should draw is 300W and so the PSU the op has is more than adequate.

    I hope that point is pointy enough for easy comprehension.

    Edit - Further clarification. To me the logic seems fairly simple. +650W PSU - 300W (570 max power draw) = +350W = Plenty of headroom = Question answered. Whether you like how detailed my response was or not is your own problem. I answered the question correctly and with enough explanation as i felt necessary. If you really wanna stand up and start beating your chest saying "but... but... but...!!" then send me a PM. His question has been answered multiple times, why do you want to make an issue out of it?
