OC3D Review: XFX Black Edition 850w ATX PSU

[JN]

"XFX's entry into the PSU market may look like it's a prop from an alien sci-fi movie, but how will it cope up when placed up against the OC3D anal probe testing procedures?"

XFX Black Edition 850w ATX PSU

Have to say that video is great for suspense! Rather shocking for such a big brand though. Be interesting to see if they say anything.

Still think that people will buy this no matter what just because it looks good and has XFX written on it.

 

[I Hunta x]

ok is it just me or does the top of that psu look amazing?

the bang want that big in the video tho =\ i was expecting the camera to wobble and someone nearly cacking them self

other than that good review from the quick scim i gave it for now.

You can always turn up your volume for a more authentic reproduction. Unfortunately all the "cacking" was done when the first unit went bang right as I had my ear pressed against it while listening to the fan noise.

Jim = Mr Calm.

Couple of cracks and he doesn't jump, flinch, move, gasp... nothing.

If BFG and XFX have taught us anything, and to a certain extent the woeful air performance on Corsairs 800D, it's that companies should stick to doing what they do best.

And has high efficiency + good rippling as long as you don't let a madman with heavy testing equipment near it

Yep. So long as you don't exceed the rated output then there should be absolutely no problems. The MAX Load test is just there to test the capabilities of the PSU (much like CPU overclocking) and the safety features of the unit. I also test every PSU for SCP - Short Circuit Protection (which is kinda like OCP anyway) to ensure that they power off when a connector is shorted.

Unless somebody tests thse features everyone just takes for granted that they work until one day their PSU turns into an arc welder

Quite a shame really.

This ruins XFX's brilliant reputation.

Hope they fix this problem quick.

Nice review Jim, good to see a bang finally

I wouldn't say it's a problem not being able to deliver 120w over the rated load, as it's not rated as a 970w unit...

Not exactly, but then you could apply that logic to a car. What would happen if Ford sold a car that officially had a top speed of 150mph on paper, but down the motor way you got it up to 165mph and the wheels fell off.

IMO you either limit the speed to what is on the paper, or make sure it can cope with going that little bit faster without falling apart.

Naughty! :O

I didn't think of it like that, suppose you're right.

 

[tinytomlogan]

Something I also thought about is if its like that new, what happens overtime, will it get worse? What happens if theres a storm or something the overcurrent not working properly could be a very bad thing imho

 

[zak4994]

First of all, I doubt 120 watts is a "little bit" more.

Secondly, unless you were stupid enough to SLI two/three cards that require more than 850 watts, then you deserve to have your PSU go boom. Common sense peoples.

Again, this is another form of stupidity. If the car states that it can go up to 150mph, why would anyone be stupid enough to try and go over it. lol

I don't necessarily recall any event in the past that resulted in the some for of computer hardware suddenly spiking up its energy draw up by 120 watts.

 

[tinytomlogan]

Actualy Zak 120watts is nothing for a high end PSU, the Corsair 750w does near on 1000w within ATX spec in the hotbox and the 1000w has been tested again by us @ 1480w.

Read all the PSU tests and we test them all the same, this is the first (pair) of PSU's we have had in that have died in this way

Bah! Blasphemy! I never go wrong(!) lol.

Not the point ttl lol.

Wtf? you dont OC your cpu/gpu huh?

This is Overclock3d.net, not stockcrap.net.

Are we heading the way of a 'natural selection' argument again If safety features are used then they must work IMO. No point in having railings on the edge of a cliff if they are stuck there with blutack

 

[tinytomlogan]

The point is mate, the over current is a big fail in that PSU, and its a massive problem.

Did I forget to mention common sense?

If you are an enthusiast who wishes to overclock, then I would recommend that you buy yourself a better, more powerful PSU.

Gah! I will give in. CBB to continue this discussion lol.

Have OC3D tried to contact XFX yet?
