I just bought the ati 5770 to replace my 4670 and was wondering if this stats for temperature are ok and signs that the computer is underpowered, currently having a 360 PSU from a dell computer.

Just saying aswell that the Witcher 2 looks great and has good fps

They're fine. Hardware enthusiastic will take you to task because those temps are 10-15 degrees higher than that of what you get replacing stock fans with third-party cooling systems, but it's totally not needed for normal people. So, when someone inevitably posts taking you to task for not having your temps in the 30s, keep that in mind.

I have no experience with your video card, but a random link I click on google searching for it says 450 watt power supply required, so if the "360" in your post means 360 watts, it might be underpowered.

I'm always hesitant in telling people to replace part A, because it can quickly spiral into "oh, but you should now replace Part B, oh wait, Part C too" etc etc and quickly spiral out of control. ;p You probably SHOULD replace the power supply unit, but how far you want to go in switching out components to your Dell is entirely up to you. If you're playing the Witcher 2 fine, it doesn't seem like the underpowered PSU is having any drastic effect on your video card.

yea it means 360 watts, I hope it has no problems for long periods of time...

An inadequate PSU can damage other components or just die from being taxed too hard. I'm sure we can all relate to death by overtaxation, but when it comes to PSUs it's entirely avoidable by upgrading it.

Try and avoid getting anything too cheap too. Unbranded / OEM ones often oversell the actual wattages they're capable of.

Power supply fan at 10k RPM? I hope that some kind of mistake :-)

Those temperatures looks just fine for idle temps. You might also want to check the temperatures under load as well, just to make sure the cooling is keeping up when it counts (with those idle temps a reasonable expectation would be around 60-65 for the CPU under load, and 70-80 for the GPU under load). If you're seeing temperatures significantly higher than these under load then you may need to change the settings for your fans to ramp up a bit more (unfortunately the default settings for many GPU fans often won't crank the fans beyond 60-70% of max even if the card is burning up).

Also, as others have said, a 360W PSU is really pushing it- you'll probably want at least a 500W PSU to be on the safe side. And keep in mind that the PSU is probably the worst component to skimp on (just edging out the motherboard), and not having enough power (or having inconsistent power due to getting a PSU that doesn't fully meet its specs) can at best mean random crashes as components don't get the power they need when the need it, and at worst damaged hardware due to power fluctuations playing havoc with the more sensitive components (such as CPU and RAM).

Can anyone recommend me a PSU the only reason I haven´t bought one was because I was afraid it wouldn´t fit on my case(see pics)

Ugg I really don´t know how to put my system underload but running TW2 1920x1080 high settings, Ubersampling off(pic load)

@tburger : that's what was showing on everest, but now it's alittle less than 5k

60ish buck PSU......

Here's one that should more than meet your power supply needs and is reasonably priced. Double check that it will fit (compare the listed dimensions to the dimensions of your current PSU).

And those load temperatures look quite reasonable with nothing to worry about (for a comparison my aging 8800 is hitting 90 C when running TW2, but still seems to be holding up just fine).

ty all, i'll check them out see which one fits best
