Help Choosing: Corsair HX520 or HX620 PSU?

[Deadalus]

My knowledge of power needs is non-existent , so I could use some help. Based on the following system specs, will the HX520 be enough, or would I be better of getting the HX620?

AMD Athlon X2 4600+
ASUS A8N-SLI Premium
2GB Crucial Ballistix RAM (4x 512MB @ 2.8v)
nVidia GeForce 8800GTX

Creative X-FI Extreme Gamer - PCI
Linksys Wi-Fi Card - PCI
Hauppauge WinTV-NOVA-T 500: Dual Digital TV tuner - PCI

2x SATA hard drives
2x IDE DVD writers

6x USB devices
3 or 4 case fans

Thanks for your help.

Because you have a GTX I'd say 620.

And isn't 2.8 a really high voltage for RAM?

Yes defo the 620. You've certainly got enough components to power and it always helps to have a bit extra left over in terms of Wattage.

No way. The 520W is way more than enough. You only need the 620W if you're going SLI, and even then I reckon the 520 would cope fine.

Not for DDR ram. It's about average.

Yup i'd say save the extra as even if you upgrade your cpu for a c2d etc a 520 should handle it with ease.

620 purely for future upgrades.

Thanks guys, it seems we have a bit of disagreement

Would the 520 be cutting it fine for future upgrades?

Not unless you plan to go SLI.

520 cosiar will be fine for quad core and 8800 gtx no need for 620 unless going SLI

 

[weringo]

A Corsair 520W could potentially run SLI anyway, its that good.

Thanks guys.

The 520 has a yellow label on, the 620's is red. I liked the red better, so went for that one
