Today I bring a quick look at a new PSU recently listed by OcUK from a very large PSU manufacturer that designs PSU's for themselves and also make PSU's for other well known companies. with a track record for making award winning power supplies.

Packaging.

So the PSU comes in a white box.

Some of the key features such as the NIPPON capacitors the Platinum efficiency rating and the ECO thermal intelligence switch.

This graph shows the fan curve on rise and fall.

A multi language user guide is supplied also explaining the ECO thermal intelligence system.


Cables and accessories.

All the cables come in a pouch.

This is what comes in the pouch,

• One cable > 20+4pins MB power connector. 58cm between connectors.
• One cable > 8pins (4+4pins) EPS/ATX 12V connector. 68cm between connectors.
• One cable > 8pins EPS 12V connector. 68cm between connectors.
• One cable > 2 x SATA + 2 x 4pins Molex. 54cm to the first connector, 12cm between the rest.
• One cable > 3 x 4pins Molex + 1 x FDD. 54cm to the first connector, 12cm between the rest.
• Two cables > 4 x SATA. 54cm to the first connector, 12cm between the rest.
• One cable > 2 x 8pins (6+2pins) PCI express connector. 58cm between connectors.
• Four cables > 8pins (6+2pins) PCI express. 58cm between connectors.

A 2pin European plug is supplied but OcUK include a three pin UK kettle lead also.

Four thumb screws are supplied.

All the cables are modular including the ATX 24pin (20+4)

The braid is excellent and the wires are not visible.

All the individual wires are black which really helps.

The connector for the PSU end on all the cables have these jewel like connectors.

These are the rest of the braided cables, the SATA and Molex cables are all flat type which will help cable management around the HDD cages etc in modern PC cases.

PSU body.

The PSU has its own bag.

Stunning to look at in its all white design.

Power rocker switch and a 2-way switch to control the fan, this puts it in either ECO mode or Auto mode which is always spinning and usually at full speed..

All of the power on a single 12v rail.

The powder coating is lovely to look at.

All the connectors are well finished and give a firm tight feel when used.

The illumination of the connectors in daylight is plenty and certainly not dim.

But in the dark they really come to life. Only the ones receiving power illuminate, but some bleed seeps through from the others.


Fan noise.

My test system is the same as used here.

Test setup,

i7 [email protected].
Gigabyte X79-UP4.
Kingston HyperX Predator RAM@2133MHz.
Kingston HyperX 3K 240GB SSD's in RAID0.
Gigabyte R9 280X 2-way Crossfire.

Below are two videos.

The first is 5 minutes of BF4 and a further 5 minutes of Crysis3 gameplay while recording the fan in Eco mode, basically it doesn't spin up, I think I saw it spin up for a minute once last night then it went passive again after about 20 minutes of playing BF4 online.

The second is just a short video showing the fan noise starting of in Eco mode then into Auto mode then back to Eco mode.

Needless to say this PSU is effectively silent at all times. It never spun up to full RPM in Eco mode during my testing of it, during a 2 hour online gaming session I believe I caught it spinning maybe two times in total and that was only for less than a minute each occasion and that was at a slow RPM which again you can not hear.


Final thoughts.

Utterly gorgeous to look at and silent during operation this PSU is fantastic, the cables are nicely braided and of good length for big tower cases. The biggest overall impression is one of absolute silence, no fan noise, no coil whine, no nothing, if it was not for the fact that the PC is ON and the connectors are illuminated you wouldn't think it was working.


Pros.

• It's white.
• It is gorgeous.
• It is silent in Eco mode.
• The cables are well finished and have a nice braid.
• 5 year warranty.


Cons.

• Lol wut? ok it is £209.99, but this is a Platinum rated high quality 1KW PSU, I see Gold rated units for similar.


Thanks to OcUK for the PSU and Ethermaster for the banner.

Hi there

I think your testing will truly show to people how quiet these power supplies really are.

Indeed.

Silence is golden.

Here are the reviews which will include voltage, ripple etc,

Certainly no messing around with the quality of this PSU.

You said that when the fan is in normal mode it spins full speed all the time? Did you test the normal fan mode when the pc is idle? I'd like to know how quite it is then.

This is from techpowerups review

"Because of a very relaxed fan profile, the PSU's fan only started to rotate halfway through the 40% test and was almost inaudible at up to the 60% load test. Super Flower's Leadex Platinum operates quietly under even extreme conditions, which most users will appreciate. We would, since the fan profile is very relaxed, pick its normal fan mode over the semi-passive one if we had this unit installed in our system. In the latter, the fan spins up rather late, allowing for high internal temperatures that affect the lifetime of its electrolytic caps the most. The fan operates at incredibly low speeds most of the time, and I would leave it on all the time to cool this PSU's internals down. That said, Super Flower surely knows the tolerances of the components they use best and wouldn't tune the semi-fanless operation as they have if they weren't sure of it; and nor would they offer a five year warranty."

See the second video, that's Idle.

Sitting here typing this I have it flicked into auto and can hear the fan and air movement.

They must have changed the profile on normal fan mode or there's an issue with yours.

According to the techpowerup review in normal mode at about 200w the fan is still off and spins up to 600rpm at about 400w. In eco mode it starts spinning even later.

There's nothing wrong with this unit, guess they changed it or something, again its in Auto mode and spinning at what appears to be full speed.

But who cares about Auto mode when Eco is silent

 

[stulid]

Do you still have it out on a desk or in a case?

On the desk still.

From what I am reading and experiencing, auto is fan always on but RPM varies with temp, Eco mode is semi-fanless and doesn't spin up until the internals reach 45c.

I don't mean to be pedantic (it is an amazing PSU no sane person can deny that) but it does (or did when you did the review) cost 40% more than the EVGA P2 1KW which is the exact same PSU just in different casing with non LED connectors (and an extra 5 years on the warranty), so if you don't have a case window the is no reason to take it over the EVGA unit, most review sites did mention that.

Was the EVGA equivalent even available in December?

At the time I did this overview it was the cheapest 1KW Platinum rated PSU in stock and still is.
