Is 1050watt enough for 3x r9 290's and xeon 1660?

If OCing no.

If stock then maybe if it's a premium unit that can run with higher than rated draw.

Our own 8pack has said the SuperFlower 1200W Leadex's that OcUK carry can power 3 290Xs.

With that unit he actually ran 4 overclocked.

What he said was the Corsair AX1200i could only just manage 3 cards, whereas the Superflower 1200W was able to run 4 cards without issue.

It depends on which model of 1000W, if its a Superflower Platinum or a very high-end Antec unit, you should be able to manage it fine. But if your doing it on an average 1000W unit then no.

I have the super flower leadex gold 1000w psu. That will be fine for 2x290's oc'd I'm guessing but not for 3 right?

I have the Platinum version, it can do three at stock, did not try overclocking, but on the Gold model I am really not sure, you might struggle.

Looking for highest current should i choose the 1300w Gold with 108A or the 1200w Platinum with 99A?

The 99A Platinum is newer, but the 108A Gold is rated higher.

We've tested the Platinums 1200W with 4 cards and fine. 1000W with three cards and fine.

We've not tested Gold's yet.

Be careful, there is a problem with these SuperFlowers.

One problem means the brand has a problem?

So far we have sold:-

110x 1200W platinum = Only one returned as un-wanted (not faulty)
120x 1000W Platinun = Three returned, 2 un-wanted, one faulty.

100x 1300W Gold = Two returned as faulty, as such we have reported the faults to Superflower to investigate.

260x 1000W Gold = Two returned as faulty.

46x 550W Fanless = Zero returns.

600x 650W HX Green = Zero returns.
540x 550W HX Green = One returned un-wanted
376x 450W HX Green = Zero returns.
127x 350W HX Green = Zero returns.

90x 550W Amazon = Zero returns.
40x 450W Amazon = Zero returns.
13x 350W Amazon = Zero returns.

In short a sub 0.5% failure rate on the brand, the most reliable PSU brand we sell so far.

This is our EVGA report:-

26x EVGA 1500W = 2 Faulty
37x EVGA 1300W = 2 Faulty
110x EVGA 1000W Platinum = Zero faulty
90x EVGA 1000W Gold = 3 Faulty
103x EVGA 750W Gold = 4 faulty
40x EVGA 750W Bronze = 1 faulty
65x EVGA 650W Gold = 4 faulty

We sell and promote both brands, but EVGA so far is proving not as reliable as Superflower.

Irrelevent of the brand you will always get the odd faulty unit, some brands more than others but out all of all the PSU's we sell the early days for Superflower are extremely promising to the point that we are now building most of our SI machines with them after nearly 2 years of internal testing. 8 Pack is using them to achieve world records and I am using one in my personal PC at home.

A brand we had more failures on though still acceptable was OCZ with a 3-4% faulty RMA rate, this was one of the worse brands we sold but still a pretty good record.

We are very confident in the SuperFlower brand and that the overall failure rate will remain below 0.5%, maybe even 0.25%, something that no other brand we sell has achieved so far.

As these are the same PSU's in different casing I would have expected identical failure rates, but I guess the sample size is too small really, However I still have full faith in Superflower

Different batches, different couriers and they won't be identical. Superflower we are selling is latest revision and I know they made some revisions to the design since our earlier samples.

Cheers for the stats Gibbo. Good to know there's been no returns on the Plat models (touch wood)

.

It's been awesome thus far and completely silent. Only thing to be heard in the rig is the XSPC D5 pumps.

To be honest, 1-2 people get a failure on a forum and think the brand is sub-parr seen it several times, they fail to realise the 100's of customers who are happy don't come and post to say so.

Corsair, Bequiet, Seasonic, FSP, Superflower, Antec, EVGA are all top quality PSU brands.

Also the NZXT power supplies we sell are built by Superflower we believe as well.

Silent_Scone · 13 Jan 2014 at 12:33

At the end of the day power supplies no matter what form factor eventually fail. And I don't really take notice of DOA reports as frankly that's not really a good way of evaluating build quality. As I've said before the tallest trees always take the most wind, and people are more likely to take note when higher quality brands are 'failing'.

Too many contributing factors with power supplies. Faulty main supplies, power surges, negligent overloading etc. Expensive as they may be they're almost consumables lol

It is the interaction between us and OCUK staff here and the fact that Gibbo is willing to provide hard data in a public forum that keeps customers like me coming back here to buy my gear.
Another order from me this morning for another gfx card, will see what to do about psu once I have measured power draw at the wall

Three of my 290Xs plus 3970X overclocked had no problem bringing my 1200i Corsair PSU to it's knees and the cards were not even running flat out.

Kaap would it be possible that you do a few runs with 1/2/3/4 cards and check what Wattage the whole system pulls?

I shall just chime in here as a very satisfied owner of a Superflower 1000W Leadex Platinum

Only mildly annoyed that I bought it while they were £209 instead of £170

Just out of interest, what was the failure rates like on XFX? worse than normal? or was it simply their returns process and service that turned you guys away form them?

Agreed, remember most people post when they have had a bad experience. Many people with good experiences stay quiet. The same happens with cars, one person by a ford has a bad experience and shouts about it, sadly the 1000s of people who are happy dont say a word.

SiDeards73 · 13 Jan 2014 at 13:18

+1 for the aboves comments, i love my Superflower 1000w Gold, brilliant PSU, deathly silent, glowing plugs! it has GLOWING PLUGS! come on how is that alone not a winner?

but seriously, people will only hear complaints, people rarely stop to put praise where its warranted. I cant speak highly enough of OCUK and their compontents

You're all very invested in this brand which has only popped up on the shop in the past few months. Tone down the love fest.

Superflower have been arguably the best PSU OEM for a long time, the only ones that really come close are Seasonic and Delta, I personally bought my EVGA Supernova P1000 because it was a Superflower Leadex unit. Just because they have only in recent years started selling own brand consumer PSU's (their server PSU's have been well know for a long time) and have only recently become available at OcUK doesn't make them any less awesome.

Think of it in the same sense as the Ford Mustang finally coming to the UK lol.

Just like how I had to have a Superflower PSU for my home PC, I also want a 2015 Mustang too, V8 of course.
