4870 psu

[bwat47]

Ok, I just upgraded from my 9600gt to a 4870. I only have a 450 Watt corsair 450VX psu. It seems to work fine so far, but will I have any problems down the road? is it good enough to power my machine with no issues? The psu has a single 33a 12v rail.

Machine:
95 watt Phenom 2 2.6 ghz 1.28v
4x1gb corsair xms2 ddr2800
250gb WD sata drive, 320 WD sata drive, 640gb wd sata drive
Visiontek 512mb 4870
Creative audigy 4
2x 120mm fans 1x 80mm fan

Use this calculator to see how many watts your current configuration uses and how much headroom you have.

Ok, I used that site and it gave me this: (with 90% processor TDP and 30% cap aging to be safe)

Reccomended: 405 watts

+3.3V +5V +12V
5.1 A 15.0 A 26.1 A

So I guess I'm safe?

Corsair does have its own PSU finder ya know:

According to Corsair themselves, that Corsair 450VX PSU will be enough for your setup.

I had seen a lot of what I mostly assumed was misinformation like OMG THE 4870 TAKES 300 WATTS FULL LOAD so i was a bit nervous about whether I had enough juice.

A 4870 actually uses around 130W at full load. The 300W would be for your entire system (actually probably less than 300W).

The only card that would even come close to that would be the HD4870X2.
