Voltage Regulation
| +3.3V Regulation | |
| Load | Voltage |
| 10% | +1.58% |
| 20% | +1.21% |
| 50% | +0.15% |
| 80% | -1.06% |
| 100% | -1.61% |
| 110% | -2.27% |
| +5V Regulation | |
| Load | Voltage |
| 10% | +0.74% |
| 20% | +0.46% |
| 50% | -0.30% |
| 80% | -1.10% |
| 100% | -1.70% |
| 110% | -2.04% |
| +12V Regulation (Worst Rail) | |
| Load | Voltage |
| 10% | +1.01% |
| 20% | +0.81% |
| 50% | +0.19% |
| 80% | -0.35% |
| 100% | -0.77% |
| 110% | -0.96% |
First we take a look at the voltage regulation. All rails start relatively close to their optimal values. +3.3V and +5V reached about -2% during overload which is decent. The four +12V rails show even better results. Even the worst rail stays over -1% at highest load. FSP has btw. no problems with dynamic loads. We saw some tests from 50Hz to 10KHz where the load current decreased after a small duration with satisfying voltage results.
Ripple and Noise
| +3.3V Ripple Quality | |
| Load | Ripple and Noise |
| 10% | 26mV |
| 20% | 23mV |
| 50% | 31mV |
| 80% | 38mV |
| 100% | 42mV |
| 110% | 44mV |
| +5V Ripple Quality | |
| Load | Ripple and Noise |
| 10% | 18mV |
| 20% | 18mV |
| 50% | 21mV |
| 80% | 30mV |
| 100% | 40mV |
| 110% | 46mV |
| +12V Ripple Quality (Worst Rail) | |
| Load | Ripple and Noise |
| 10% | 30mV |
| 20% | 32mV |
| 50% | 45mV |
| 80% | 72mV |
| 100% | 97mV |
| 110% | 116mV |
These ripple & noise measurements tell us that this Gold series was planed as an affordable offer while most other 80Plus Gold PSUs show better results -- for much higher prices. +5V and +12V are very close to 1% ripple & noise. However all rails are within ATX specification and most PC systems shouldn't reach 100% load or more. Those results from the +3.3V rail with 26mV at low load and 23mV at a higher load are very unusual.

No price for the Aurum?And where can you get it?

In Holland I payed 90 euro incl. shipping, for the 700 watt version without the modular cables (FSP Aurum 700). I have been very happy with mine (Computer: 5850*2, 10HD's, Q9550@3.6GHz, etc., etc.).Also see the review at:

UMM???FSP's products are almost allways in the "You-get-what-you-pay-for" class. This goes for the high-end as well as low end parts.
Please consider that FSP has a huge range and DOES produce low-end (even if not "trash"-end) parts.
To my experience, most of the time, they are either cheapest or on par with competition at a given price point. Though nobody does miracles for peanuts in the PSU business ...

$155 is too expensive.I picked a Seasonic X-760 at Microcenter one months ago for $149.

It's nitpicking, but I'm disliking the use of the by the way abbrevation.Is a full review upcomming? I'm having a bit hard time getting any solid information except for the numbers from this 'rushed' article.
But on the other hand, I never say no to more content from Anandtech, it was worth the time reading it :).

Can we finally compile all these PSU reviews into say the "Anandtech PSU Charts" so we can really compare the ones you review?etamin - Thursday, July 21, 2011 - link
You can get a seasonic x750 gold on newegg right now for 166 shipped. It's a shame there are so few 100% modular psus with quality performance and conservative designs.ratbuddy - Saturday, July 23, 2011 - link
What use would a 100% modular PSU be? Everyone's going to use at least the 24 pin and CPU connectors, no reason to add cost making those detachable.dhiiir - Friday, July 22, 2011 - link
Fast economic development, science and technology quickly.Is a full review upcomming? I'm having a bit hard time getting any solid information except for the numbers from this 'rushed' article.The store's products, the quality is really good. Cheap, authentic. There are genuine brand-name shoes and clothes. Now share it with everyone.-.www.upsfashion.com- I believe you will like it.
