i will laugh my ass off, if you come back in 1 month saying your pc shut down...
actually it runs on 300W..i just want to check that can my PSU handle it...

check out these posts...they said it can/is running fine on 300-350 watt PSU

HP don't manufacture their own PSUs, they hire Delta, FSP, Hipro, Bestec, AcBel, or LiteOn to manufacture them for them.


Things would be a lot easier if you could take a large, clear picture of your PSU's label.

The rig will run the card, but the PSU will be alot louder in my experience. Because it's running alot of power just run everything including the GFX card and if you push the card it will demand slightly more from the PSU.
You will get by for now on that PSU but get a 500 watter later on for $45.

+12V is rated for 15A, or 180W. This is a 250W PSU in modern usage. I frankly wouldn't trust any GPU higher end than a GT430 on it.
He's right. Like I said earlier range ~260watts. It is simply not enough or you're will be running at poor performance due to lack of power.

Semi-correct conclusion, completely wrong reasoning. A PSU is rated at its OUTPUT power, not its input. That means the PSU can output 320W continuously. However due to power wasted during the conversion from 120VAC to the DC output, it will consume more power from the wall. So at 320W output, it will be using 320/.8 = 400W input from the wall.

The reason I call it a 250W is because it is built to an older PSU electrical standard, ATX 1.3, that puts more power on the +5V and +3.3V rails, which is useless to a modern machine that gets 80% of its power from the +12V rail.

That's a completely non-ATX12V compliant custom server PSU from Lite-On. With +12.1V (to nominally distinguish from +12V) and +12VSB.

I have no opinion on its capabilities.

So what should i do now to check its capabilities ??
post #19 of 26
I'd get something at least 450 wattish...I had a 350 watt running a 4650 on a pentium4 dell 8400 rig. and the computer was just loud all the time because i finally realized it was trying to stay some what cool.. Yeah the 350 watt psu ran for over 5 years and I donated it, but I really noticed a difference when upgrading to a 550 watt psu it was quieter and I knew that rig had more than enough power to run smoothly, plus I could keep it longer and use it for upgrades.

nice conversation yall.

Well now i have two options go for 6670..which can be used with my current psu...or wait for 3-4 months...save enough money for both 5770 and a PSU...

Will battlefield 3 be able to run on 6670 on high settings at 1280*768 or 1366*768 ?? i want atleast 35-40 fps.. or is there a another GPU that u guys can recommend for this...Plz keep that in mind that my screen max out at 1366*768 and i'm not going for a bigger screen as this one works for me just fine..
