A Closer Look – Exterior


First impressions of the Leadex Platinum are superb, it’s a brilliant looking design with a really unique fan grille. What is shocking is that it’s black, given that the box is white and the small images on the box are of a white unit, this could be confusing to some consumers.

The paint work is gorgeous, it’s not quite matte, it’s not quite glossy, but it looks great either way. The contrasting white fan blades certainly add to the appeal too.

The base of the unit, certainly nothing much to see here, just a blank panel.

The main specifications sticker shows us that we’ve got a very powerful 45.8A on the +12V rail, so we know it’s going to be great for those overclocking their CPU and/or GPU.

Down the other side, a fairly understated by stylish Super Flower logo.

Virtually edge to edge ventilation around the back, so that fan should have little issues with shifting heat out of the unit. It’s also nice to see a master power switch for those times you need your PC completely powered down.

This is by far the best part, those funky 3×3 grid connectors. The clear plastic design has a built-in white LED lighting and they just look a bit cooler than the stock connectors we’ve seen time and time again. There’s also a very handy auto and eco mode switch, which toggles the fans hybrid cooling mode on.

Cabling

The cables are of a good quality and all the more power heavy cables are thickly braided and round. The connectors are colour coded on the hardware side of things, although I’m not sure why and all black, or keeping with the clear theme of the PSU end connectors would have been preferred; for me personally at least.

All the peripheral cables are flat-type, which makes them a heck of a lot easier to route and better yet, they have more uniform black headers on the hardware ends of each cable.

    Couple of confirmations of things we can read in this test, plus one small issue found:
    • Bulletproof build without the doubt – every detail of PSU case has been made neatly, using proper solid materials.
    • Full set of aesthetic cables, easy to manage them as I wish, long enough
    for most of cases – connectors are pretty solid on both sides.Full set of aesthetic cables, easy to manage them as I wish, long enough
    for most of cases – connectors are pretty solid on both sides. Cables finishings are in finest quality, once connected they stays secure & tight in the sockets. Bag for unnecessary cables is an nice add-on too;
    • Stability – the voltages are really like frozen: idle, moderate load under full load, or quick changing load – doesn’t matter, still great stability;
    • Stone cold – now will be something quite interesting: I’ve got this unit in NZXT Noctis 450 PC Case, inside of integrated shroud. The fan is set in “ECO” (hybrid semi-passive mode), fan hole is located on top (I didn’t fit it up side down by purpose), where is only 2-3mm distance to the top of the shroud. Could say the heat must be generated inside, resulting that fan will by running very often. Nothing like that… To be honest it didn’t run even once yet. It is stone cold. The lowest case fan (with very reduced speed), located at the front of PC case surely makes the air moving towards PSU a bit – and this is the only ventilation there. Really the fan in this Power Supply is just like additional bonus – been given, but we never needed to use;
    • The only small issue is SATA supply cable. As most of the PC cases are
    now designed with PSU located at bottom I found this cable is designed
    other way round – like for PSU’s located at top of the case. That means
    if you connecting two or more drives (I have three HDD’s currently)
    firstly the lowest Drive needs to be connected using farthest plug we have on the lead, than next one above etc.
    After connect the last top one, rest of the cable needs to go back down to PSU –
    makes this area unnecessary busier than we need, which tat is only thing to consider if we have smaller / very low budget PC case.

    Generally – it is really silly to compromise own choice buying cheapest PSU. And now it is a lot easier to make right decision – we can reach for not very expensive Hi-End Power Supply in the price of Mid-Class. Cannot choose better…
