FSP Epsilon 80Plus 600W

Internals
Inside we find a three heatsink design. Some designs from Seasonic also use three heatsinks, two on the primary part and the other on the secondary side. We see the same approach with FSP's Epsilon 600. The secondary heatsink is a little larger in volume than the others since it needs to dissipate more heat from the hotter components attached to it.
The heatsink on the far right makes it very difficult to see the components behind it, but the main cap is made by CapXon and rated at 420µF and 420V. The second heatsink for the primary part has two rectifier bridges attached to it on the upper section. It's also easy to spot the secondary capacitors and their respective manufacturers. FSP uses two different suppliers, a few from Teapo and some from CapXon, both of which we have seen many times lately. Since the basic design is several years old now, we didn't expect to find anything extraordinary within the design. However, this design is still sold today and you can expect good quality from PSUs that use it.

The funny thing about FSP's Epsilons is they have 4 units submitted at the same 600w output for 80Plus:FSP600-80GHN

All of them are 80Plus certified and the 80GHN and the 80Plus 600 hit the exact same numbers ;)

looking at newegg, there is also a 600 80Plus Everest model. You yourself have seen that the Everest platform is just a renamed Epsilon.WT - Wednesday, August 6, 2008 - link
I own an Epsilon FX600-GLN, and the first thing I thought when reading this was 'Wow, AT is reviewing that older PSU today' but soon found this was just a minor update to that PSU. Its been stable as a rock and handled everything I've tossed at it, with an overclocked Q6700 and soon a 4870 to power up 24/7. For the money I paid, it was a no-brainer. If I had an extra $50, I'd splurge on the PCP&C 750 unit today.JarredWalton - Wednesday, August 6, 2008 - link
FWIW, Newegg has the http://www.newegg.com/Product/Product.aspx?Item=N8...">PCP&C 750W on sale right now for $110 after MIR ($140 before rebate). That's no as good as a couple weeks back (when we did the PSU roundup) when I grabbed that for $100 *without* an MIR! Still, considering this PSU is only in Europe and prices are merely okay, that PCP&C is definitely one of the best buys in the US right now.RallyMaster - Wednesday, August 6, 2008 - link
is a ball bearing fan. Anandtech's review and news quality has been dropping as of late. Please get facts right. Do understand that Yate Loon D12SH-12s would be the sleeve bearing version which is rarely if ever used in a horizontal configuration like inside a power supply.C'DaleRider - Wednesday, August 6, 2008 - link
Hmmmm.....no comment on whether the power supply is independently or group regulated (HINT: it's a group regulated power supply which is old tech and not seen as nearly as good as an independently regulated one.)Wonder how FSP, using the old Epsilon platform, managed to get its ripple/noise, according to this test, "....different voltages delivered low ripple and noise results, staying well within specs." Odd that almost every other reputable power supply testing website has found just the opposite...
Then to gloss over the less than top shelf component selection when it comes to capacitors as the unit is stocked exclusively with Teapo (primary) and CapXon (secondary)...neither of which is seen as anywhere near being a first class component like Rubycon, Chemi-Con, etc.
But so far we've just seen praise heaped on each and every power supply tested.....never have they had one that failed to be great...which begins to make a lot of their testing suspect. Never downgrade a power supply for substandard interior components or build quality, never a demonstration of ripple, no MOV on the primary (all the other reputable PSU-makers on the block are doing it... why not FSP?), yet we fccus on three heatsinks...but no mention of what's attached to them, like the capacities of the seimconductors for the primary and secondary sides....or what are on the OCP controller, or if the OCP controller actually functions, and on and on.
Incomplete.....and yet we have another power supply that sails through with flying colors despite the company, using this same platform, having huge problems with ripple.

"All of the different voltages delivered low ripple and noise results, staying well within specs." Thanks you for this enlightening revelation! I have no knowledge of what this "ripple and noise" means, but since you say it's "within spec's" I don't care to find out. Something in your writing makes me tingle all over... and want to trust you unquestionably.Sincerely yours,

FORTRON / FSP Power Supply Units are unreliable hardware devices.Failed just after 784 days of normal use (about 3500 hours only)!.

Funny :)Ripple seems to be harmonics in the output (harmonics would be periodic variations, one of the most common could be at the frequency of the main electricity input - 50 Hz in Europe and 60 Hz in USA - or at its multiple/submultiples (25 Hz, 100 Hz and so on).
Noise is just that - random variations in the output. In the end, I think noise is less dangerous than ripple, as ripple might create standing waves/resonance with ripples in other AC-powered equipment (monitor, printer), which could lead to problems.

You name is half right at least. Thanks for being a fucktard. I guess they should make up graphs showing ripple voltages just to appease people like you, because that's so much more useful than a statement on whether or not there was ripple. Let me guess: you read Jonny Guru, right? Do you post there and complain about his lack of fan speed and noise level testing?I'll get worried when I see a cruddy PSU tested here that gets praised. So far, the cheapest PSU tested by Anandtech seems to be about $80. Yeah, I'm shocked that ripple results have all been good. Seriously, someone send these guys some Antec SmartPower, Raidmax, Rosewill, Logisys, Powertek, CoolMax, etc. PSUs. You know, the ones that claim SLI and Crossfire support and yet cost under $60. Or send pretty much and PSU that comes with a case. If I see some of those getting by without some serious problems, then I'll get upset.
