HX520W, Strong enough?

Long story short, my Type-R 580 died. Fans flicker from it and there are unhealthy noises coming from it and it refuses to load, so I'm getting rid of it, and getting a Corsair HX520W PSU.

I ran outervision's PSU calculator and I'm okay (rec, 514w). I planned all my eventual upgrades and assumed that an X2900XT uses as much as power as an 8800GTX (is this safe to assume they will be around equal).

I have read PSU101, but still am not fully understanding of the whole 12V, 3.3 and amps etc. I will read it in more detail to try and understand, but is it safe to assume that my system (see below) could handle it?

E6400 (may upgrade to E6600) {non-overclocked}
Asus P5W DH Deluxe
4GB Corsair DDR2 PC2-6400
X1900XT (upgrading to X2900XT)
3 x SATA HDDs, 3 x IDE

I appreciate your help,

It'll do very well on your system and should handle the X2900 with ease but I'm not sure how much the R600 cards consume.
 
when you are using top of the line; no holds $$$ video cards why not choose a PSU in the same manner

I would sooner get the HX 620 watt
 
I plan on getting the X2900XT when the price drops a bit heh. I won't be doing upgrades for quite a while after that. I ran the Pro version of extreme outervision's PSU calculator, here's my results with all my due upgrades (Please note that I assumed an 8800GTX utilizes the same amount of power than as X2900XT uses):

System Type: Dual Processor
Motherboard: High End - Desktop
CPU: Intel Core 2 Duo E6400 2130 MHz Allendale
CPU Utilization (TDP): 85% TDP

RAM: 4 Sticks DDR2 SDRAM
Video Card 1: NVIDIA GeForce 8800 GTX

SATA HDD: 3 HDDs

DVD/CDRW Combo Drive: 1 Drive
DVD-RW/DVD+RW Drive: 1 Drive

Sound Blaster - All Models: Yes

USB: 6 Devices
IEEE-1394 FireWire: 1 Device

Fans
Regular: 3 Fans 120mm;

Keyboard and mouse: Yes

System Load: 100 %


Recommended Wattage: 502 Watts

Recommended Amperage:
+3.3V +5V +12V
7.2 A 18.7 A 32.0 A

As you can see I fit well within the A range. I'll run it later with an E6420 (conroe, not allendale) to see if it gets any higher heh.
 
A HX520 would handle that system with an 8800GTX easily, but there's still no definitive info on the power consumption of the X2900XTX. Given that these new cards will use a new 8pin PCI-E connector, as well as a 6-pin PCI-E (i.e. POTENTIAL maximum of 300W vs the 185W TDP of the 8800GTX), it's safe to assume the power consumption will be significantly higher than the 8800GTX.

Having said that, I would be surprised if the HX520 wouldn't be enough, but the HX620 would be the safer choice.
 
I just don't have the cash for a 620, so I went for the 520. As the X2900, I may very well get the XL version instead!
