I was just curious because I get asked about that exact psu and there is no documentation anywhere on the net stating the 12v rating. Thanks

It's not very difficult to calculate. Look here for the way I calculate it. It's about 95% accurate IMO and quite easy to master. :)
 
Ok, how many amps is it rated at?
Model RP-500-PCAR = +12V1@16A + 12V2@16A = ????????

Dell 305w = +12V1@18A + 12V2@18A = 22amps
264w maximum combined wattage on the 12v
264 divided by 12 = 22

And I ask again,
What's the amperage ratting on the Coolmaster?

What I post I can back up with facts, how about you?
Your being called on this.
Please post your amperage rating with documentation.
 
It has an amperage rating of about 31A. Use the aforementioned method for confirming this. And not all PSU makers post the total wattage rating on the +12V rail for all their PSUs.
Why the menacing tone? I have never given out misinformation to anyone AFAIK and if I may have, I have admitted it as such. There is no documentation existing for that CoolerMaster PSU indicating the total wattage on the +12V rails. You seem to be holding a grudge for some reason. Why is that?
Oh, and that thread only seems to show how to calculate total +12V rails amperage for when the +12V rail total wattage is given. The method I use uses all the other ratings to get the +12V wattage and consequently the amperage.

Nothing towards you.
This psu is a Tier 4 (out of 5)

I do not believe it's 31a
tell tale signs:
Maximum Power 500W
Efficiency >70% typically

"Oh, and that thread only seems to show how to calculate total +12V rails amperage for when the +12V rail total wattage is given. The method I use uses all the other ratings to get the +12V wattage and consequently the amperage"
why isn't it given?
which method do you use? I saw 2 different you used in your linked thread

Enough of this, life is too short to argue over a $10 psu (I still won't recommend it) and kimsland is still an a**
 
It's post number 10 I believe. And the efficiency gives you the amount of power that the PSU delivers after pulling a certain amount of power from the socket. Since it's a 500W PSU and it has 70% efficiency, it pulls about 700W or so from the socket. However, the PSU will rarely be loaded to it's maximum level during normal usage so actual efficiency may actually be about 75% or so when 350W is being used, for example. How would that affect total amperage? I'd like to know so I can take better care in recommending things to people next time. Sorry if I sound like I'm teaching you stuff that you already know.
Also, is it really necessary for PSUs to have documentation? I've seen people having problems with this one but they're usually ones who've overloaded it with a Q6600 and stuff or ones who've received a defective one. I doubt the OP's system will have a problem with it. After all, if you can afford to get an 8800GT, you can also usually afford to get a good PSU like the Corsair VX450 as well. However, it's the OP's choice and as an alternative recommendation to the CoolerMaster, I recommend the Corsair VX450.
 
I doubt it. It pulls much more power (~95-98W) than an 8600GTS (~71W) so it'd need a PSU much better than the current one, which is just enough for an 8600GTS. As I said, look for a Corsair VX450 as your new PSU. Your current one will not be enough for the HD 3850.
 
Hmm, odd. The HD 3850 probably has an excellent cooler, since the ~95W figure is the reference spec from AMD. Reading through other reviews though I agree, the HD 3850 has the same power draw as the 8600GTS, so it should work.
 
I thought the same as well origionally.
Anandtech is one of the few review sites I go with, as well as TechSpot and guru3d.
 
SO would you huys both agree that getting the Radeon HD 3850 will be able to work with my computer without frying it?
 
General consensus is Yes (from reading through the posts)

But you may think about updating your Power Supply (ie new Ram and Video Card)
 
It would be a good card but for games, it's just okay really. For Crysis you should go with at least an 8600GTS.
 
will i be able to play crysis on medium

will i be able to play crysis on medium with the 8600 gt xxx and if not what is the lowest price i can get for the best card for my system ( that will not overheat my system)
 
Meanest, baddest Card for the 4700?

Hello all :eek:)

I also have a dimension 4700, and just replaced the psu with an Antec 500w. The system also has 4GB of memory, and a Soudblaster X-Fi Card installed. My question is what is the fastest / biggest / best (BADDEST) card I can stuff into this system? So far the best card mentioned in this thread was the HD3850, and I noticed that is a PCI-e x16 VS. 2.0 board, will PCI-e x16 VS 2.0 Cards work with the 4700? Thanks for the input in advance!
 
Yes, PCI-E 2.0 cards will work in your PC. Also, the best card you could get for it would be determined by the type of PSU. Antec makes multiple 500W PSUs, so tell us what series it is from i.e. NeoPower, Basiq, Earthwatts etc. Since each PSU has a different amount of power available on the +12V rail(s), that would affect your choice of video card. Let us know what the series is and we'll suggest an appropriate card.
Lastly, keep in mind that a very fast card like an 8800GT will be bottlenecked by your current CPU, which would limit performance to the level of a cheaper card like an 8600GTS. So buying the 8800GT would be a waste in this case. The previous case is an example and is meant to show you how to spend your money best. That's also what we're here for. ;)
