Will my 430w PSU support an 8600gt?

[bigshotceo]

Right now I've got an xfx 6800gt video card in my computer. I've been thinking of upgrading to an 8600gt (likely one of the cheaper ones) and was wondering if my 430w thermaltake PSU can support it. My system specs without the video card are as follows:

CPU: Core 2 Duo 6420, stock speed.
RAM: 4 sticks of ddr2 RAM, stock speed.
Motherboard: ASUS P5LD2 R2.0, stock speed.
HDD: one 7200rpm SATA hard drive.
Optical drives: one DVD-R burner
Other: one 200mm antec fan on "low", four 120mm Antec tricool LED fans on "low" or "medium". One 2.5 inch external HDD.
PSU: Thermaltake 430 watt PSU with dual fans.

Assuming you power supply has one of the PCI-E power connectors, it should be fine. You don't have much hardware putting any strain on your PS.

When in doubt you can always plug your system specs into here and see what it says:

That should be OK. I see listed power draws for that video card version of 45W - 65W and a minimum power supply size of 300W. One easy way to check a PS is to just hold your hand by the fan exhaust and gage the heat. If it's exhausting heat like a hair blow dryer or you can smell hot parts, it's likely overloaded.

The overall output power of a power supply doesn't always mean much. There are several different voltages available, +12VDC, -12VDC, +5VDC, -5VDC, then usually about +3 - 4 VDC for the CPU. And you can have more than one +12VDC rail. Each one has it's own power rating. On newer PSs, the +12VDC rails have been increased for power because of all the drives being used. And newer CPUs have higher power needs than CPUs from a few years ago. Video cards probably run off the +12VDC and the +5VDC and possibly the +3VDC rails.

Here's a ATX PS pinout that shows the voltages:

Yes it will. Also a good place to check necessary wattage is more advanced eXtreme Power Supply Calculator[/url][/list]
