Recomend a PSU core i7

post #1 of 6
Thread Starter 
If I build this system do I need to upgrade my power supply if so how many watts do i need?

SinTek 500w SLI PSU
GIGABYTE GA-X58A-UD3R
Intel Core i7-950
CORSAIR XMS3 6GB (3 x 2GB)
Radeon HD 5850
Sound Blaster X-Fi Platinum
2x HDD
DVD combo
fan controller
5x fans

My PSU is 5-6 years old it was high quality at the time, but SinTek has faded into the darkness. My guess is that its fairly close but If I need to upgrade I will get a CORSAIR 750w or 850w HX. This is because I am planning for future video card(s) upgrades, so the 850w would probably be best giving me a bit more room for $25 more.

Do you need to? You could use that. Do you want to upgrade? If so corsair makes an amazing psu. 500 watts should be able to power that no problem but your over clocking abilities may be strained

Even if you crossfire, or tri-fire your 5850's you shouldn't need more than a 750W, go with a nice Corsair unit, Seasonic, or Antec.

Cant go wrong with any of those

You can run that rig on a 500-550W PSU all day long... (actually less, but overhead/efficiency is worth considering)
Could prob run a pair of 5850s w/ a decent 550-650W psu..

Do you plan to do any overclocking?

I don't know anything about SinTek, but I would recommend a solid 650W power supply like a seasonic/corsair (same stuff), silverstone, antec true power... theres alot of suggestions...

If you have no desire to ever go up to dual GPUs a 500-550W would do you fine. If you do... get a 650 or a 750 and it will last you a long time.

Oced i7 can take up to 230w depended on voltage, 5850 max to 160w, X-fi sound card, fans and others, may be around 500w (42a/504w on 12v). Corsair 750hx can do 62a/744w on 12v plenty of power and more room for future upgrade.
