I know your tired of these, but I have both due to an odd reason. So now I need your help, as I am no PSU guru ;)

Basically I am 99% sure I am getting a system that is being sold on here.

Important specs are as follows:

EVGA GeForce 8800 ultra
EVGA 122-CK-NF63-TR LGA 775 NVIDIA nForce 680i SLI
Intel Core 2 Duo E6400 Conroe 2.13GHz 2M shared L2 Cache LGA 775 Processor
(1) 400GB 7200 RPM 16MB Cache SATA 3.0Gb/s Hard Drive
(2) SATA(150) Seagate 160gig drives Raid 1
(1) IDE Western Digital 250 gig
CORSAIR XMS2 DOMINATOR 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800
LITE-ON light scribe dvd-rom burner
Pioneer dvd-rom burner
3.5" Internal Floppy Drive

Now it would come with

FSP Epsilon FX700-GLN

I just bought

OCZ GameXStream OCZ700GXSSLI ATX12V 700W Power Supply

In the pictures of the FSP Epsilon it looks dead on the OCZ except for paint color.

Which one would you pick and why? It’s obvious that one has to go.
 
They are the same power supply, so 6 one way half a dozen the other performancewise. The rest to consider is system load, and support. To venture a guess OCZ will have better support ;)

Thanks for the reply ;)

Well I will take your word for it, but the pictures did look spot on. I was just gonna take the ocz, but I am a PSU dummy in a since. I can tell you who makes your notebook, but I dont know about who would make your psu :p

OCZ it is, I am aware of the ripple this unit has, but we will see what it does in the future.

Guess I get to sell the fsp for $70 shipping :p
 
If I was in your position I would sell both an pick up a Corsair HX620 or something of comparable quality. You're buying some top-notch components, might as well get a top-notch PSU to feed them.

I don't want to get into a flame war, but do you really think that Corsair is any better than the OCZ? Please, explain your reasoning.
 
The Corsair doesn't have out-of-spec ripple near to full load. That would make it better, right there.

That's a pretty good reason, I guess :p

I wouldn't know why someone would run their PSU at full spec anyway. :eek: :p

Point taken, /but/... it's one of those situations where you pay for 700 watts from a big name like OCZ, you should be getting 700 watts of usable power, not 625, then another 75 watts that'll slowly kill your components should you make use of them.

I'd never suggest anyone run their PSU near max spec. The degradation and risk to components just isn't worthwhile.

I thought you were setting yourself up as flame bait until I saw your response. :D

Seriously... why even bother with an FSP Epsilon based platform when there are better options from other OEM's?

The Corsair, for example, is an excellent example of a great PSU for the money.
 
I've had a OCZ 700w for a while now--no problems. I did read some reviews before I bought it and none showed this problem. AFAIK junnyguru's is the only one?:confused: Also I do remember a post by DavidHammock saying nobody else could reproduce this ripple, but that was some time ago.

I know both are good units, but I didn't know why the Corsair unit was better than the OCZ. I am still learning the PSU market (too much info really). I really thank you for your diligent work on this topic. (Yes, and I thank Paul and a few others here too.)

Lee at PcPer hit the ATX limit with his sample, I was unable to reproduce it on the 12v rail with the OCZ 1010w as it failed to power up at anything over 80% load. But at 75% the 3.3v/5v rails were out of spec on both units I had. The platform in general suffers from noise/ripple issues.
 
So, just one review of the 700w? I don't think anyone should get rid of a PSU because of one bad review. When we see a bunch of "OMFG it took out my whole rig" threads I junk mine.;)

It is a platform issue. Take a look at the pictures from the 1010w and the 700w ;)
 
 
The only review I had read before buying:
JasonRebel said:
Using a Tektronix 2215 Oscilloscope, we check for AC ripple that is present in the DC power. We only checked the +3.3V,5V,+12V1, and +12V2 rails (not the -12V or 5Vsb). Potential frequencies could be in the 60Hz range (which is what the AC line power is in the US), or in the higher KHz range closer to the PSU's switching frequency. The ATX & EPS guideline tolerance is 50mV p-p on the +3.3V & 5V rails, and 120mV p-p on the +12V1 & +12V2 rails.

I've decided against displaying a table due to some recent emails I've received from people. Just because one power supply has maybe 10mV more ripple on a rail than another does not necessarily mean it's not as good. As long as ripple is within spec then one should not worry. It's when you see a lot of noise (far exceeding specs) on the rails that something is wrong, and in those cases it's probably just a faulty PSU that needs to be RMAed. If anything is out of the ordinary then we will report it, otherwise just take our word that everything is okay.

Everything checked out okay with the OCZ GameXStream 700W power supply, all numbers were well within tolerance and very consistent with other high-quality power supplies we have tested.

I guess that makes three. It's odd he didn't show scope screens, but that's about as boring as...as a PSU review. He did not give much info on the testing eather.

Can you link to the review? I'd be interested to see what kind of load he was putting on the unit during testing.
