OK guys- Looking for a good PSU to power my sub$2K New Rig in a week:


P180B case
Q6600 G0 2.4GHz (will OC with Thermalright 120 ultra extreme to 3.2Ghz)
eVGA 8800 GTX (Stock)
Asus P5K Deluxe
2X 320GB Seagate Barracuda 7200.10 SataII
2GB Corsair XMS2 Dominator 1066

Newegg has the OCZ GameXstream 700W
http://www.newegg.com/Product/Prod [...] 6817341002
for 89.99$ after rebate/Promo code

ClubIT has the Corsair 620HX (620watts)
http://www.clubit.com/product_deta [...] o=A6200027
for 89.99$ after rebate

With a little difference in shipping charges (clubit charges 9$ for shipping)
It's the same price.

Now don't take me wrong, But I was going to go with the Gamexstream for a while, but then saw this great deal today, so I'm in a dilemna now...

Quality-wise, I know the Corsair is a little better, but the gamexstream has more wattage, but both are great PSUs I heard....

So, which one should I get then, in my situation?

Thanks

Sounds like JonnyGuru would go for the Corsair based upon the GameXstream review which references both. Not sure, but is sounds like for $10 more she likes the Corsair. In fact, the Corsair could almost never be a bad choice. That is quite a deal for both IMHO.

---------------------------------------------------------------------
So now that you've had a chance to see this power supply from the outside to the inside and have seen it put out 700W of power, it's time to do some grading...

Performance (weight of 40%) gets a 7.5. Everything seemed to be near perfect, with the 700W output, the low temperatures, the active PFC, the decent efficiency, the minimal affect the hot box had on the unit... then the ripple came into play and screwed the score up for OCZ.

Aesthetics (weight of 10%) is 8.5. The flat black finish doesn't quite hold up to the shiny "titanium" finish of Ultra or Mushkin, but it's still nicer than GRAY. The cables are all sleeved and the clear fan with blue LED's is a really nice touch.

Value (weight of 30%) score is an 8. It's hard not to call the OCZ GameXstream a good value. 700W power supplies don't typically come in at only $150. That said, one has to realize the Corsair review I just did. A little less power for $10 more, but it's modular and more efficient. Also, that problem with the ripple keeps coming back to the forefront of my mind.

Now for the functionality score (weight of 20%) As I mentioned, it's not modular, external or does any thing that really sets itself apart from any other power supply But the cables are plenty long enough, are all sleeved and the unit is only 5.5" deep (smallest of ATX standard PSU's) so I'm giving it an 8.5.

So it looks like the GameXstream 700W gets an overall score of 8!

Which one performs better for the price?

Are they both very quiet? (that's what I heard)

Also, which fits better into my build...mentioned above (I want something powerful and quiet)
Oh yeah, I have a P180B case (rev1.1, specs of p182).....

Both are on Tier-2 of the PSU list at http://www.tomswiki.com/page/Tiere [...] gs?t=anon. I am not concerned about the power loss of modular connectors, but do appreciate their neatness, so if it were me I would get the Corsair.

opinions? - have to order today!

Go with the Corsair. Due to the ripply issues with the GameXstream, both end up having about the same available 12 volt amps. The Corsair is a better quality PSU, plus... its modular.

No competition at the same price.The OCZ was $50 cheaper when I ordered making the it the better choice.

I know Corsairs have Seasonic S12 series innards which is enough for me. I haven't looked up GameXStream. Unless you REALLY think you're going to need more wattage or the 700W isn't much more I'd get the Corsair.
Edit: Oh... I just thoroughly read the first post and saw that the prices are the same.

For my build above, do you think I need 700W?

Will the modular cables of the Corsair help in a P180B rev1.1 case? (basically P182)
Are the cables long enough for it? (PSU on bottom for P180B)

Anyone have this combo?

how did TSIMonster get it for 50$?

He didn't say $50, he said $50 cheaper.

50$cheaper than what price?

He said that when he bought, the OCZ was $50 cheaper than the Corsair, so he chose it. With equal prices, however, as in your case, I'm seeing some votes for Corsair and none for OCZ.

...although both are quality PSUs. IMHO neither would be "wrong."

I have the GameXtreme 700w pushing SLI GTS' and an OC'd e6600. Very quiet. Very stable. I have been more than satisfied with it. Only downfall is that its not modular. But I have a huge case so it hasnt really been an issue.


My 2 cents.

Well I plugged your build into the PSU calculator, and even with an additional 20% on top for capacitor aging I come up with 538W for your system with the "actual" draw being about 448W. I guessed on a couple of figures (1.35V on the 3.2GHz overclock... I really have no idea on any of the Core series since I don't have one), and I signed you up for having 3 120mm fans and 1 DVD burner. Of course this is just a rough number because balance between the rails and whatnot will have an effect. Either should be more than enough.

One more vote for the Corsair.

Thanks for all the responsesXX

MrCommunistGen - I got 608W for system, stats being:

dual core proc
highend mobo
Q6600 OCed 3.2GHz, vcore 1.35
85% CPU TDP
2Xsticks ddr2 ram
8800GTX (stock)
2 SATA HDDs
1 DVD burner
1DVD Drive
1 sound blaster
2 usb devices (mouse/printer)
Soundblaster X-fi
fan controller
3X performance fans
100% peak load


is it because of the CPU TDP and 100% load?

Thanks - will order before 5:00 PM PST (California)

No way that needs anyplace near 608w.

120w for the CPU, 175w for the GPU, 30w for the 2HDDs, 30w for the 2x CDrom all come to about 355w and those are high estimates.

Everything else is not overly signficant.

You need to be careful when usi
