I bought a Dell XPS 8300 a while ago and it seemed like a really good deal. But soon, I noticed that the graphics card (ATI Radeon 5450) was outdated and ran quite slowly on a lot of the games I played (Crysis 2 - 15-20 fps?).
So I've had my eye on the Nvidia GTX 560 as a possible upgrade.
But I saw two possible obstacles, the power and the physical requirements of the card.
1) My system runs at 460W (more details are in the picture below - no idea what all these Voltage numbers mean).
The card needs a minimum of 450W. I was wondering if I'm cutting it too close? Do I absolutely need to buy another PSU?
2) Also, the GTX 560 is a dual slot, which I'm guessing will need two full length PCI slots.
The card I have fits in 1 (there is only 1 long slot in my CPU)
That long standing thing is my current graphics card.
Does that mean I won't be able to physically fit the card into my CPU?
well it says on the sticker that the 12v rail should not exceed 385w. normally under normal circumstances, that would pass probably with a gtx 560 but the psu cannot promise those watts. the 2nd problem is that the gtx 560 takes 2 6pin connectors(which im partially doubting that an oem will even give you 2 6 pin connectors). As a personal recommendation, I would recommend buying a ~450w psu
Is using 2 dangerous? But the Nvidia site says 2 though.
the reason why its dangerous is because if your psu didn't have a 6 pin on it already, then it wasn't built to power a graphics card of that level. using one is usually okay, and you can possibly get by with it depending on how strong the card is. 2 is likely to result in a failure.
