Overclock3D Launches Power Supply Certification Programme

Overclock3D Launches Power Supply Certification Programme

 

For the past 2 years Overclock3D has been at the forefront of independent Power Supply testing in the UK. Being the only UK technology publication at present to possess its own in-house ATE (well two in fact), we have always maintained the belief that a power supply can only be tested correctly on professional equipment, by trained staff and without any controversy surrounding using off-site testing facilities or 'sponsored' equipment.

In this time we've also come to realise that there is no definitive way for enthusiasts to identify the best PSU's on the market at a glance. ATX compliance and 80PLUS certification does not guarantee 'quality' by any stretch of the imagination, and product awards are becoming all too easy for lesser-quality manufacturers to obtain simply by sending their products to publications that are unable to correctly test power supplies to their rated outputs. It is for this reason that Overclock3D has launched its own Power Supply Certification Programme.

Our programme covers areas such as SCP and OCP testing along with stringent ripple and voltage analysis, Efficiency and PF testing and temperature monitoring. Furthermore, being the overclocking enthusiast website that we are, we have always believed in testing beyond specifications. After all it's not until you start pushing PSU's beyond their rated outputs that you really get to tell the difference between a good unit and a GREAT unit.

This is why we're inviting all PSU manufacturers to a duel!
Their PSU's vs our testing procedures.
 

At the end of testing, PSU's that pass the following gruelling challenges will be awarded with our "OC3D Certified PSU" logo. These tests include:

1) SCP (Short Circuit Protection) testing at full load.

2) OCP (Over Current Protection) testing beyond full load.

3) Stringent ripple analysis.

4) Stringent voltage output analysis at both idle and full load.

5) Efficiency and Power Factor testing.

6) Operational temperature testing.

Full details of these tests and what's required in order to pass can be found in our whitepaper here. Over the next few days we'll be directly contacting all PSU manufacturers and requesting that they submit their latest models to us for analysis. The table below shows who we've contacted and whether they've responded or not:

Great idea! It took me ages to decide what psu to get for my rig but if i saw that it had been through those tests and got your certificate would easily persuade me Quote

Cheers for the feedback guys

The certification is going to be a tough nut for many manufacturers to crack. But basically where ever you see the certification logo (which we'll reveal soon), you can rest assured that you're buying the absolute best there is.Quote

Question is this free to them or will there be costs involved. Just wondering as if its free youll get a wider range if its not only the company with the most money will be up for it.

No offence ment by this comment btw.Quote

Costs are involved in submitting the PSU's for verification, yes. However they are so small that any manufacturer would be able to afford them. This is more than what can be said for 80PLUS certification (they charge a fortune) and part of our certification covers pretty much everything they do anyway Quote

Sounds great jimbo/oc3d !! Something quite original for such a community yet its going to be one hell of a selling point for me. I'd much rather see a psu pass a oc3d test which i can trust rather than one of the other more well known sponsored events Quote

We'll be busy boys thats for sure...... Just getting the public to know what we already do. There is only one place/person in the UK that does power supplies properly...... and its our very own Jimbo Quote

Cool just a thought that crossed my mind.

I know testing equipment , Products takes a long time and to buy the test equipment all so costs money, time, bills ect ect.

Great idea guys. Just a thought...

I was looking at the PDF and something stood out to me... voltage regulation should be judged on a curve that follows the wattage capability of the unit.

In other words: 2% regulation on a 450W PSU, going from 10% to 100% load essentially sucks. But 2% regulation going from 10% to 100% load on a 1200W PSU is pretty good. You really can't set a firm 1% or 2%, etc. regulation requirement for all units across the board. Unless, of course, you don't plan to review any high wattage units. Quote

Love it, if you've got the kit you may as well test some decent hardware when you can. I think all high end PSU manufacturers should get in on this if they think they're products are up to it!

Great idea guys, looking forward to some results.Quote

Hey jonny, good to see you post. You have a very good point. I'm going to have to give that some thought. Thank god for revisions Quote

Awesome idea guys!!! Love to see someone give a lie detector test to the manufacturers cuz we all know that a fancy box with logos and claims all over it doesn't always mean it's a great product. Let us know who ends up passing the torture test and who just ends up with their tit in the ringer. Quote

Im quite interested in this.

Would also be good to get some generic units tested for an example of why you should buy a high quality unit.

Be more than up for sending over a few of the "horrific" units for testing.Quote

Homepage list of manufacturers has been updated.

We've had a couple of manufacturers so far agree to send units in - they're just finalising which ones.

...and..

We've had one manufacturer respectfully decline to be tested after they asked if we could test at 40C instead of 50C Quote

I've yet to think of a way that we can accurately test noise. Ya see, in order to stress the PSU so it spins up its fans the load tester needs to be on. However when the load tester is on there's absolutely no way you could get an accurate noise reading as the load testers are sooo noisy (can hear them 2 floors down!).

I've tried switching the load testers off for a few seconds, but some psu's are so quick to respond to the drop in current that the fans immediately throttle down.

Sound-proof box is another option, but yet again if we're conducting testing at 50c, that requires a heating element and fan to be in the box with the psu.

I'll happily test fanless PSU's, but I dont think there's a manu on earth that would send me one once they see that the testing is done at 50c (heatsink quickly becomes a heat source).Quote

so all that I need to do is invent a noiseless tester but yeah i see your point Jim. 2 floors down is a bit ouch, you got ear plugs?Quote

Bungral
Was really interested to see how many of the manufacturers would be up for this and figured it would be the quality ones that would happily agree.

Can you say which ones have agreed yet, or not really?

If enough agree to the tests, then the ones that turn it down for whatever reason will look bad regardless of their reasons.Quote

LOL yep. Unfortunately 100% of the load testers power draw is converted to heat. So its a case of trying to dissipate anything up to 1.6kw of heat silently

A couple of manufacturers have already agreed. One has already been tested and has failed. But before I say who it was I want to publish the whole review, as they only failed by the skin on their teeth and I think its a bit unfair to say "FAIL" without explaining it more.Quote

I just removed Silverstone off of my mental shortlist for psu vendors I will buy from. The competition is too tight for one to wimp out from testing in what is a very realistic environment. Bad show Silverstone.

Tom, have you looked at the testing done in the US by Hardocp.com? They (and jonnyguru.com) are the best psu testing I have seen and who I use religiously for psu selection.Quote

I've been around for almost five years now and I have never considered that to be true. I've always felt we've had one of the more open and understanding communities here at OC3D. I would be sad and disappointed if that has changed in the time that I've been less active.Quote

To be honest I don't mind links to other sites being posted so long as it's not in excess, and the content on there isn't going to mislead our readers.

We're never going to be like two certain other websites in the UK that actually block the word 'overclock3d' from being posted on their forums. Tut tut Quote

Because for it to get the PSU Certification from OC3D, it had to pass extremely stringent test conditions, including being only 2% off the target 3.3v on the 3.3v rail, which was where it failed. Since at full load on that rail it had to be no less than 3.234v, but it hit 3.21, which falls outside 2% therefore it failed. If it was able to pass the 3.3v test, than it probably would have gotten a Gold Award as well as a certificate.

For a PSU to get approved by OC3D, it will have to be the best PSU in the market, even than I doubt the best PSUs out there right now are capable of succeeding.Quote
