Will the GeForce 7600GT card work with my stock 300watt PSU?

by deeppolverizingkidd / March 19, 2007 9:13 AM PDT

I have a computer with integrated video memory and I want to upgrade it to a dedicated video card. I'm looking at the GeForce 7600GT card. It says that it requires a minimum 350-watt power supply and 18 Amps on the +12V. My stock PSU has 300-watt and 19 Amps on the +12V. Will the GeForce 7600GT work with my PSU? My system configuration is below:

Intel Pentium 4 Processor with HT
1 DVD/+-RW drive
1 SATA 160GB 7200 RPM Hard drive
1 Gig of pc4200 ddr2 sdram (1 stick only)
1 PCI 56k modem
1 PCI 10/100 NIC

I plan on adding another 1 gig of ram in the future. Everything else will stay the same expect for the possible 7600GT card.

"18 Amps on the +12V. My stock PSU has 300-watt and 19 Amps on the +12V"

That actually is a difference?? Is that normal?

BUT your OVER ALL MAXIMUM WATTAGE =300 no more no less

In reply to: difference?

it isnt a matter or amps here cause it is DC voltage we are talking about what MATTERS is the overall WATTAGE that the PSU can supply and a card like a 7600 will make a 300 watt power supply SCREAM RAPE jump out of your case and run down the street crying it hurts it hurts if it will even run at all them cards have not one but TWO 12 volt dongle rails supplying the multi processors not too mention the fact that your mother board and processor might not be fast enough to power the card right too

Doesn't the 7600GT uses little power?

I thought that the 7600 GT uses little power. I read somewhere that the 7600 GT use about 40 watts only. I don't believe that my system is fully loaded so wouldn't it be able to run then?

while still if only 40 watts there

your hard drive/s require power cd dvd roms usb ps2 mouse all that needs power to run and NVIDIA RECOMMENDS A MINIMUM OF 400 watt power supply for any card from 5900 up

MINIMUM of 350 watt
by deeppolverizingkidd / March 23, 2007 8:44 AM PDT

Nvidia recommends a minimum of 350 watt for the 7600GT but that minimum 350 watt is for a fully loaded system. I don't believe I have a fully loaded system, do I? So based on the configuration I have for my computer listed in the first post, does that still mean I could still use my 300 watt stock power supply?

get a new psu.

In reply to: MINIMUM of 350 watt

i was new psu phobic. didn't want to perform surgery on my computer. but installation of a new psu was a cinch after all. 10 minutes for me. no post op problems either. always a good idea to upgrade the psu. it puts less wear and tear on the system to have more watts. the more watts the merrier. then you don't have to worry, and you can just enjoy your gaming.

Try It, but probably go with 400 watt
by AdamJ34 / March 27, 2007 4:53 AM PDT

The 7600gt is a midrange card and isn't a huge power hog like the newer, higher end cards out there today. It only draws 36 watts at peak and 16 at idle vs. 109 watts for the Radeon x1900xt at peak. It will probably work fine with your 300 watt supply. Give it a shot and see what you think. Otherwise, a 400 watt supply should be plenty. If you're looking to upgrade for the future start at 600 watt+.

One more thing...
by AdamJ34 / March 27, 2007 4:58 AM PDT

A standard 7600 gt 256mb only requires 18 amps on the 12v rail so my guess is that you should be ok.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
