Is this PSU enough?

post #1 of 16
Thread Starter 
I'm planning on building a rig with the following components:
EVGA 780i SLI
E4600 CPU
G-Skill 4GB DDR2 1000
2x 500GB SATA (RAID 0)
8800 GT

I was thinking about using the Ulta X3 800 watt PSU. Will it be enough to power this rig and let me upgrade later, possibly to SLI?

Thanks

Yeah, an 800w PSU is actually overkill for what you've listed....it'll be enough. It'd be enough if you wanted to SLI GTX's or Ultras later.

You don't need 800watts, you could get buy right now with 450watts and with SLI you'd maybe at most need 700watts with those components.

Agreed. I think a $80 Corsair 550VX should get job done.

Get a better brand than Ultra. Corsair, Seasonic, Antec, and FSP Group are all good choices.

Agreed. I'll never buy another Ultra power supply after my current one. It works, but it's a major PITA to connect to side mounted hard drives due to the bulky grips on the ends of the cables.

Don't forget, 'brands' of PSU are really made by a smaller number of manufacturers. Seasonic makes some of the better PSU's for Antec and Corsair. The corsair 750 is made by CWT, which also makes the high end Thermaltakes. The X3 series is made by andyson, which has been making excellent psu's for them. Granted many people have reported problems with lower end Ultras, but there are plenty of crap Antec's too....

Also, FSP's I wouldn't recommend as it appears ripple can be pretty bad.

As far as 800 watts, doesn't hurt to have headroom , you could get away with a bunch less...

x3 800, if you can find a decent price is a good bet.
corsair 620 @ $145 isn't bad either.

LOL, read this

I dont care if they make 1 or 2 ok PSs (like their 1000watt)to me ultra is NOT a PS brand I would EVER consider again.
I agree with pbpenguins412 recommendations and the others that mentioned the Corsair 550s (great value)
