Newegg has SeaSonic G Series 550W 80 Plus Gold Certified Modular Power Supply (SSR-550RM) for $75 - $15 rebate = $60 with free shipping. Thanks calistyle

I don't know anything about this specific model, but seems like a great price. I have a Seasonic I got 6 years ago and it's still running strong.

It's a new series meant for people who want quality components but on a "smaller budget".

I'd probably jump on this (or the 650W if it went on sale) if I haven't bought the X750 earlier.


[edit] I wish Seasonic (or all manufacturers) shorten the length between each SATA plug...

Ridiculous to advertise it as SLI ready with a wattage that low.

This should be able to run 560ti's in sli... A complete system on full load with a pair of 560ti's only use 450 watt on load. And this is a quality psu too. People overestimate WAAY too much on the wattage they need for rigs these days..

Pretty much.

CF 7950s would be fine. [legitreviews.com]
SLI 660 Tis would also be fine. [xbitlabs.com]

I should specify. I'm not saying that you should, I'm saying that you can. A solid 650W unit is plenty for SLI/CF anything though.

I mean a pair of 6770s or 550tis should be fine, but considering this is a quality psu I would say it's pretty safe to run 560's unless you're doing massive ocing.

Shows how much you know. A good quality 500-600w psu, can easily sli/crossfire two low/mid end cards.

Good deal.

So, realistically, for this build...

- i7 3770K / Z77
- Noctua NH-D14 Cooler
- 4x 7200 RPM HDD (RAID10)
- 2x SSD 128 GB
- 1x BD-R
- 1x BD-ROM
- 4x 120mm Fans
- 1x 200mm Fan
- Possible GTX 570 / GTX 670 in the future

Is this enough?

I've been leaning towards a Seasonic X650 or X750 for a while (especially with the recent deals) but if there's no need to go for that much power...

Yes, more than enough.

This I have a corsair 550w crossfire ready but it can't do it on most the cards.

I used a Kill O Watt meter this week to test my rig. I pull 252 watts when I run Prime and FurMark. I am selling my SeaSonic X750 and switched to a Antec High Current Gamer 400w. However I was eyeing up this SeaSonic 550 today. Modular and Gold Rating.
