HardOCP review (http://enthusiast.hardocp.com/article.html?art=MTU2Niw5LCxoZW50aHVzaWFzdA==)

Cliffs, Sirtec built, similar to a cheapened FSP Epsilon

[Travis]

Yeah Doug has a freezer for OCZ-branded units.

Can we conclude that low +12V output indicates an overrated crap?

FYI: TREC cap
http://www.trec-con.com/

according to: http://capacitor.web.fc2.com/

A question for Spectre: How did the two units fail? Overheated? Triggered OPP? Voltage/ripple out of spec?
I wonder how they'll perform in room temperature conditions.

[Spectre]

Well I don't see it at capacitor web but that looks like them.

They both failed by shutting down. The first restarts at lower loads, but the second blew the switching transistors.

Sounds like a Sirtec alright ;)

The TREC name follows this row. It's regarded as "caps not frequently used in PC".

The newest Lian-Li units look similar externally...wonder if they are the same junk internally as well

[Super Nade]

I don't know why a reputed company would put out something like this? A dodgy OEM, probably rated at 25C and at peak power. Very disappointing. Plus it is priced so high. Why will somebody go for this when you buy a ES800 for < $100 or something else from OCZ's own stables that performs better for less? Seems worse than Best buy's Rocketfish crap. :confused:

Probably? Lian Li has always used Sirtec in the past.

[Travis]

Same Sirtec might not be the same junk.

Ignorance of the average consumer? There are people out there who think OCZ is one of the best PSU brands around...and they have built their reputation on a few decent units. People will look at the OCZ name badge and instantly trust it, they will look at the exterior and think it looks slick and they will see the "pro" moniker and think they are getting something exclusive and top of the line. Then they might even see a website review that maeasures voltages using OCCT and think they have a great unit.

Worse is Lian-Li who is charging about $70 for PSUs possibly built on the same platform as these. Everyone knows Lian-Li cases are top quality...so they wouldn't sell a POS PSU now would they?

[Travis]

Excuse me... what is "POS"?

[TechSalvager]

Piece Of Shit ( POS ) sorry mods can edit that if need be
or Point Of Sales ( POS ) depending what use it used for

A dodgy OEM, probably rated at 25C and at peak power.
I show this review to our Sirtec reseller and he emailed Sirtec asking for some clarifications.
When and if he receive an answer I'll put it here.
Meanwhile my friend told me that internally that unit is almost identical with Sirtec HP-550-G14C.

[Zap]

So, maybe the unit does reasonably well as a 550W?

I'd edit Hutch's avatar before editing the word "shit" used in a contextual manner.

What shocks me the most is the test report. For me this actually gives the whole PCP&C "Testing Process" a black eye. All of us knew things like this would happen when OCZ bought PCP&C....

Oh... that reminds me.... You went through two of these things, right?

Did you compare the two test reports? Were they actually different or the exact same?

[Spectre]

Different serial numbers, slightly different final wattage, and efficiency.

The test reports I have of two Silencer 750W are slightly different even though the efficiency is the EXACT same on both I have.

[SnooP]

test report by random number generator? ;)

So you are saying PC Power and Cooling's crap actually can stink?

Heh, it looks like his 600W brother did well (http://www.pcper.com/article.php?aid=644&type=expert&pid=1). :wtf:

[Spectre]

Same components just 600w ;)

Also, it damn near went out of spec on the crossload, and Lee only runs his at roomtemp currently.

[Travis]

Also, it damn near went out of spec on the crossload.

You can't blame a group regulated unit for that, right? +12V loaded 2A and other two rails under full load, it's an abnormal load pattern and Intel doesn't require that kind of crossload.

If you are going to sell it in an environment where independently regulated units or DC-DC, etc units don't well then yes. The group regulated design is a cheap design. Why should its poorer performance be praised when better designs exist and do a better job :confused:

[Ninja7]

So wait a sec, this "pro" version is worse than the normal episilon version ? :confused:

Never had an OCZ Epsilon, but the Epsilon platform has always been flaky....

[Ninja7]

lol, tell me about it :p

Though ive had one and this Sirtec built "Pro" version seems much worse.

[Spectre]

I would rather own this than an Epsilon.
