Soooo, After doing lots of research I think I finally got it. For the last few days (And yelling at forum users everywhere) ive been asking questions about weather or not my PSU could support an upgrade.
I havnt been able to figure out how many amps my PSU can supply cause THE LAST THING I WANNA DO IS FRY IT!!! aggh (Rant). Anyway. Specs

Specs-
Windows 7 HP (64bit)
Intel Core i7-2600 Quad 3.4Ghz
8GB DDR3 1333Mhz RAM
Nvidia Geforce GTX 550TI

PSU 12V+ Rail Specs.

600W

12V(A)16amps
12V(B)18amps
12V(C)12amps
12V(D)10amps

So my original question was ---- The HP rep and other people have said that replacing the 550ti with the 660 shouldnt over power my system based on my PSU. I, like any other person, dont really trust The big Manufacturers. My question is do you think that this would over power my system? ---

Ive read that the 660 requires 24Amps on the 12V+ Rail. Now looking at that spec page, none of those values are near 24Amps.
Ive also read that the 550ti (Whats currently in my system) requires 24amps (wth?)
So this cant be right. If it requires 24amps then my PSU should be fried right?


Ive read that in order to figure how many amps your psu can provide, you take the total wattage available on the 12V+ Rails and divide that by how many volts (In this case 12...duh)

My psu said (Pic of PSU HERE!!! )

http://s1336.beta.photobucket.com/user/simmons333/media...

12V(A)16amps---
12V(B)18amps---= 540W (My attempt at a good bracket)
12V(C)12amps---=
12V(D)10amps---

So If im right, my psu can provide

12V / 540W = 45Amps.

So am I right? Do I have enough power to provide for my 660??!?!

Ive been ranting in my head for the last week to figure the out... Thank you!

If your computer can handle a 550 TI. a 660 shouldn't be a problem

For sure your power supply can power up a GTX 660. It can power a GTX 680, you can even put TWO GTX 660's and it should work with a decent power supply.

680? My case is tooo small sadly. Two 660s? Sadly, HP doesnt know what SLI means lol. Plus, Even I dont want to "Balls to the wall" an HP PSU. I figure with my -

CPU
GPU
HDD
2 RAM sticks
DVD drive
MB
Exhaust Fan
G510 Keyboard
Wireless Mouse
and sometimes some cheap 15 speakers that ill be quite comfortable with a 660 (Power Consumption wise) =D

Nice. For me, I might get that card as well, I think my power supply should be able to handle (PSU at signature). Or I might wait for next generation. The HD 6770 is doing fine for me right now. Anyways, good luck on your new card.

The 550ti requires 28Amps!???

I should be A Okey then =D mUHAHAHAH. A
Also, ty for the help you too

Anyone else feel free to still put your input in


That is really weird. 28 amps x 12 volts = 336 watts. The GTX 550 Ti isn't going to use near that much power.

Its not the card that needs 28 amps, they recommend a power supply with 28amps for a fully loaded gaming system and that card.

If that 540W(Thats 45 amps) is your combined(sure looks to be), you have LOTS of power for that card.

If it makes you feel any better, I am about to run a 650 ti on a 300 watt power supply :) . It does not even worry me(22amps is more then enough for my light weight system that will be getting the 650 ti).

lol o.o. Well, running a GTX 650 Ti on a 300 watt power supply might work, but you forget about the one 6-pin power connector for that card. I don't think any 300 watt power supply have a 6 pin...

You did the math right. Total Watts on 12V rail divided by 12 will give you the amps available. Also as mentioned thats for the total system, not the card. The card itself will use around 130ish watts(?) so thats only around 11A or so. That is why your PSU hasn't fried.

I am sorry for the thread Jack.

I put it on the power meter(my UPS) and games only take about 140 watts at the wall and adding prime pushed it to just under 180.

Yeah, I figure to make sure It doesnt trip anything ill do some little tests.

Best thing I can figure is to Load up CIV V (Late game) to allow maximum CPU useage
and allow the card to render frames unchecked (As in vsync disabled) for about 30mins to and hour

CIV V is the only Quad Core intense game I has atm

just to Make sure Maximum power useage will be reached

This was the first released one. Actually got a new fan for it and it help ALLOT(thanks XFX. the first one was surly defective). It was louder then I wanted. they have MUCH louder cards then it, but remember everyone has a preference(For this system, I want quiet. Even swapped the power supply fan for more quiet.).

I was thinking. My current setup is a single HP 2311x 1920x1080 monitor. I was planning on getting another for an auxiliary monitor. Mainly just to play Youtube videos or basic web browsing while gamming. This shouldnt cause any power strain right? Max mabye an extra 10W?

I wouldnt think it'd be since Monitors are powered from the wall

Nvidia's current cards are VERY good at running a second screen without much extra power consumption(1-2 watts in most cases vs the 10 watts extra for something like a 7770).

Now I know on the ATI side with many cards if you open a video the video card will use its video clocks(400mhz on many cards). This in it self is a good thing as it saves power, but at current it seems the cards(drivers) are not smart enough to know they also have a game up and running so some cards get "stuck" at this speed while a video is playing. This can have a negative effect on the performance of the game.

My 650 ti(its a cut back gtx 660) will be on Monday, I can test then to see what the current Nvidia cards do with video + games(and multi screen if you wish).

Biggest thing I have noticed is that not all games work so well with the second screen on and video. Sometimes video just stops(freeze with audio going). Games with the option for fake full screen or windowed full screen work for sure.

Way back when I first set up 2 screens(Celeron 466mhz baby! 192megabytes of ram.), it was about the same. Some games blanked out the screen even.

If you want to game across the 2 screens(not always a good idea because if you play FPS your cross hair will be on both sides.) I am sure you can setup a display group.

I have a feeling you are going to have some fun with this setup.

HD 5770(for about a year and a half). Then a 4350 because(had it from my old media center) its fanless(and the 5770 works better for another system my girlfriend games on), but that thing just gets by with media(can't even use media center and surf the net without the video skipping, the 5770 handled that fine and I was playing lots of games with it when I had that card.).

okey Quick Tidbit. So the memory clock on this card is 6000 some odd something. Anyway, The card (On MSI Afterburner) doesnt go over 3084. Only thing I can figure is, is that this is due to the PCI 2.0 Slot and HP's motherboard specifications. This motherboard what configured for 5xx series cards, All of which (correct me if Im wrong) topped out at around 2052. So I guess 3Gs is the top? (poo, ill upgrade that later)

Memory is DDR(double data rate) so many times it will show as half. CPU-Z shows 800mhz for 1600mhz system memory as well.

PCI-e 2.0 will have almost no effect on the card.

GPU-Z is great for monitoring your video card by the way(sensors tab). Please note with GDDR5 it tends to show 1/4 of the speed, it us just the way this memory works, so 1200 is 4800 and 1500 would be 6000.

If anyone is still reading this. 650 ti is in :) 

seems to be smart enough to NOT clock down when playing a video and game together(you are still best to play games if windowed full screen if you can as many times video on the second screen will stop on some games).

AMD may have this fixed with new cards anyway.

It clocks a bit higher then I expected in media center(548mhz vs 324 for other media players), but all in all it works well.

Power consumption looks very similar to the 5770(maybe a bit lower in games). Being taken at the UPS, I can not see the actual DC load as the power supply efficient comes into play.

All in all, A nice quiet card(by this point, the power supply/hard drive are louder them the card) but has a very bright blue LED on the card that I may opt to black out.

So for future reference if anyone wants to know if a 650 ti with MSI's cyclone 2 cooler fits. It does, but just on height side of things.

Most of the games played on the 5770 fine, but I have not tried anything demanding(I have a dedicated system for that :)  ) yet. I know what it is time to do :) , but yes, the performance is very good for such a small system.

This is still classified as a mid end card, but mid end gets good fps/quality for the price :)
