Corsair VX550...

CPU: Core 2 duo E8400

GPU: 8800gt 512MB DDR3

Memory: 4GB DDR2 800Mhz

Motherboard: Asus P5Q Pro

I'm assuming this computer is pre-built?

I'm really stumped, I don't know what the problem could be...is there a link to your PSU somewhere?

Also remember adding the two amps on two rails don't equal your amperage, I think.

whats a PSU??siskokidd

Power supply unit.

And my pc is self built, I used a PSU I had from my last system.

Stuttering could be because of a non-fast GPU...? I don't think it's a lie if it's actually printed on the PSU...kunu822

Most PSU's overrate (LIE) about the actual specs. This is one of the reasons why it is important to get a quality PSU, from a reputable company.

So this could be whats behind my stutter in those games?

As I said in your other thread, the problems you're having does seem to be a problem with your PSU underpowering your video card. There is no way that an E8400 or an 8800GT should be performing poorly on the games you're mentioning.

As for the VX550, it is an excellent PSU. What is your budget for a new PSU?

I really doubt it. AFAIK, a graphics card'll draw as much as it needs and if the power supply can't handle it it'll just cut out. Stuttering is 9 times out of 10 caused by IO operations like HD reads/writes, so it's much more likely to be some software/service running in the background. if you're running an untweaked version of Vista then you'll get stuttering when it starts to index (which it tends to do exactly at the wrong moment). You can disable that by turning of the Windows Search service. Some antiviruses can also lead to trouble as they'll scan anything that's being read in to memory, so you could try disabling it and seeing if that helps.

The other 1 time out of 10 it's more complicated stuff like badly configured memory timings, BIOS settings, badly designed / old chipset drivers, things like that. That kind of stuff is difficult to diagnose without access to the PC, though. My advice would be : find out the chipsets for your motherboard and update the drivers. If that doesn't solve the problem, see if there's a more recent BIOS update. Try searching for your motherboard model + stuttering in a search engine, see if anyone else has had the problem.. if that all fails, you should think about replacing the power supply, but I think the PSU is the least likely culprit.
