Sufficient power for a 8800GTS system?

[P-Stew]

This is my first home built system and I just want to make sure I've calculated this correctly.

The PSU I have my eye on is the OCZ GameXStream 600w. It has 4 +12v rails at 18A and is rated for 80%+ efficiency so it seems to be just what I'm looking for and at a decent price. My build will include E6300 /w Scythe Ninja, 8800GTS 320MB, 2GB G Skill DDR2 800, 1 320GB Seagate HD, dedicated sound card, and I will be doing a mild OC. I will likely add one, maybe two HDs, in the near future and may upgrade to a GTX further down the road.

First question, is this a solid PSU and will it handle what I currently have?

Second, will this cover me if I do the proposed upgrades? Or should I jump up to the 700w OCZ since it's only 5 bucks more on newegg?

TIA for any and all replies.

Thanks a lot for the recommendation, I just made the switch and will probably order tomorrow. I had a feeling I was being overly cautious with the wattage, but I'd figured I would rather be over than under.

Now you will want a PSU with more power once you get the second video card. For that i would go to the SLI Zone at Nvidias web sight and choose a PSU from there list of compatible PSUs.

He didn't say he was going SLI. Or at least I didn't think he said that:

I will likely add one, maybe two HDs, in the near future and may upgrade to a GTX further down the road.

Sounds like upgrading from a 8800GTS to a GTX, not going SLI. Or have I misunderstood you, MP?

Yeah, at the moment I'm not planning on SLI, but things may change. I'll hang onto that list though, pretty extensive.

Thanks again for all the advice.
