Question

Hi!
I'm building two computers for myself. First is built from "spare" parts for home server/streaming machine, and second is professional gaming system.

I already have first setup's parts, but I'm wondering could my old Linkworld LPK2-30-P4 500W PSU handle it;

Phenom II 9658E @ 3,8GHz
ASUS M4A785TD-M EVO
2x4GB DDR3 1333 MHz
5x 7200rpm HDDs
Samsung BluRay-drive
2x120mm led fans + 3x120mm normal fans
Antec Kühler 620 for cpu
Creative SoundBlaster Platinum eX w/ panel
Some ****** memorycard reader :)



Second setup for professional gaming,
What PSU I should buy for this setup;

MSI GeForce GTX 580 Twin Frozr II OC x 2 (SLI)
Intel i7 2600K @ 5 GHz (going to OC, target clock)
G.Skill 16GB Quad Kit Ripjaws Z (4x4GB), DDR3 2133MHz
Samsung 256GB 830 Series SSD
WD 1TB Caviar Black SATA 3 7200rpm 64MB x 2
Asus MAXIMUS IV EXTREME-Z LGA1155 Intel Z68 DDR3 ATX
Creative Sound Blaster X-Fi Titanium 7.1 sound card

1) I wouldn't risk it. Maybe, if you drop the GTX275. Your stated primary uses do not require a discrete card anyway. If you still plan to include the 275 and the OC'd 965, get a good quality 650 (or better). Even without the card, I'ld like to see a better quality supply.

2)a pair of 580's and an OC'd i7: You would probably get by with a high end 850, but I'ld play it safe and look for a 1000.

750W? Maybe little bit overkill? Or is it? I think, maybe 550W is enough..? Like XFX 550W Core Edition ATX-virtalähde, 80+ Bronze - Jimms.fi XFX 550W...

PS. How did you know I'm from Finland? I mean you put link to Jimm's PC-Store :D

E: Should I take that 1kW PSU from XFX or Corsair modular? What would be best bang for the buck?

I'ld rather see a 650 (or better) used with the 275. On that site, the XFX 750 is listed at a lower price than the 650.

XFX or Corsair 1Kw: either would be fine.
