Well apparently they have 105C caps for both primary and secondary so in terms of quality of caps, they are probably higher quality .

I was sure the XTs had 85C caps and that was the one thing that made them dubitable

There goes EVGA's reputation of being mostly fine

 

These N1 models are rated for 25C ffs

Anyone making a water block for it yet? I think it might need one.

 

Side note, anyone know what a Tagan ITZ is? Sounds like a proto-beQuiet, with a non-freaking-modular 1300W tank bearing over a dozen tentacles? There's a guy here trying to sell one for a ridiculous number, and I'm curious as to how nuts he is and/or how good the unit is. I read something about it being a 1300W PSU with a single 12V rail...wtF?!

I found something (if you guys haven't already) on how the XT performs  

 

I know it's not L'anglais but it will do  

 

On a side note, you're right, it is indeed 85C primary and 105C secondary

Different. I believe the P is made by FSP.

i am now more confused ? ...... so VP-F (sold in US) and VP-P (sold in india) are of same quality and should be in same tier OR one is better than other? ........

 

and

 

is antec VP-P "somewhat" better than corsair VS?

Oh god that's worse than the CX greens IIRC.

The CX Greens are rated for 35 degrees iirc.......

 

My Corsair RMi is rated for either 85w or 105w .

All CX are CWT.

 

It's probably a fine one anyway (with the caveat of being 25C rated)

Here's a photo of the bottom....

Should be rated for 25C, not 35C, so the same as these new crap EVGAs

RMis have OTP set at 50 degrees IIRC

It's rated at 30C.

And the RMi / RMx is rated for 50C.

As long as the primary cap isn't press up against a heat source, the primary cap should rarely fail even if it is rated for 85C. For example, the Antec's High Current Gaming and Neo Eco series also have their primary cap rated at 85C. The secondary caps (setting aside the other specs / quality of the cap) pretty much will always be rated for 105C even in garbage like this: http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story5&reid=324

Capacitors are rated for those high temps, but the PSU temperature rating is a measure of about what temp you'll be triggering OTP

On a side note, you're right, it is indeed 85C primary and 105C secondary  

At full load, the 12V rail reads 12.36 (3% deviation), the 5V is 4.86 (2.8% deviation) and the 3.3V reads 3.26 (1.2%)

 

PFC is fine, 35mV ripple (don't say what rail)

Ripple goes up to 45mV in hot box

 

Temp on the primary capacitor is 62 degrees outside, 125 in hot box

 

Reviewer comments that even though the PSU is rated for 45c, even at 40c it lost a lot of performance and in fact XFX's warranty doesn't cover operation at such high temps.

 

Thankfully I know a bit of portuguese

 

I dunno, I might put it in Tier 4 looking at these tests. It performed just fine in ambient temps. What do you think @STRMfrmXMN?

You are getting confused with the rating of the internal components (namely the capacitors) and the ambient temperature that the PSU is rated to deliver it rated output at.

 

Also, OTP isn't configured to set off at the temperature that PSU is rated for, as the internal temperature of the PSU is still producing it own heat. If it was set at intake temperature, you pretty much will have a power supply that can shut off at 50wDC just because it did it at 31C ambient. lol

 

Have a look at the Seasonic Prime 650w. http://www.tomshardware.com/reviews/seasonic-prime-titanium-650w-psu,4690-6.html

It's rated 650w continuously @ 50C, while the OTP only set off when the secondary heatsink hit 111C

I say go for it. also, we should probably take out the BQ from the stuff we need to look into tab.

Who makes Bestec PSUs? And are any Bestec PSUs any good? 

I noticed that some business quality HP workstations use Bestec PSUs and I have never heard of that brand before.

I'm fairly certain Bestec is an OEM? @quan289 might have an answer.

[comicsansms]

In case anyone was wondering, I think the Cougar RS 650 (CGR R-650, NOT R-650, that is different) is a HEC "B500" as seen in a lot of EVGA and Be Quiet's budget product stack, 

 

Now I can morn my losses of $79AUD and sell it on Gumtree knowing that it isn't dangerous, just not very good (tier 5 or 6).

I've recently been wondering how you figure out that it's the same HEC model other than comparing photos of its innards.

I'd say they're not that great:

That being said, wasn't one they used for Workstations.

I moved the fan around with a cable tie, the large caps, coils and heatsink is in the same spot as the the picture on www.orionpsudb.com/

If it isnt a "B500" it is a very similar platform.

I would replace the PSUs in those HPs if they were worth something and were in a standard factor form. But spending $100 * 16 on spare Core2 Duo Computers Isnt worth it. 

[quan289]

Yeah, Bestec is an OEM. The PSUs in that are used in these prebuild computers by Dell, HP, etc. are generally decent / okay. After all, they don't want people to be RMAing a computer within the warranty period, so they can't simply put in a fire hazard that is unable to outputting what they are rated for in specs - that includes ones that are made by Bestec. Of course, the component selection may not be the most ideal, as they don't want people to used it too long outside of warranty and not come back to purchase a new computer.

 

If you have one laying around and don't want to spend money on a new PSU, they are serviceable where you can change the fan and recapped it to used. Of course, there are bad ones out there. For example, due to a flawed +5VSB circuitry, the Bestec -12E, that Starelement had linked to, were notorious to killing motherboards in eMachines computers.

Any PSU with lousy OTP can catch fire if you treat it bad, but only PSUs at tier 7 and below can catch fire while being used normally, that is they can go up in flame even if you give them enough air to breathe and don't use them over their rated power (but since most T7s don't have OPP, you could easily run it over its rated power and set it on fire without noticing anyway).

 

In short: Buy one on Tier 5 or up for light use such as an office computer, and one in tier 3 or up for intense use, such as gaming or a workstation, and you'll be fine.

Finally decided to replace the Time Bomb with this:

Should be here within a week.  Odds are Friday or Monday actually, I'm pretty close to one of the warehouses and things I order from them usually get here in ~2 days.
