Enermax Platimax D.F. 750W 80+ Platinum PSU Review

Specifications

As we can see above, there are four +12V rails. Personally, I prefer single rail design but I guess I’m just used to maximum power on a single rail for extreme overclocking where it’s usually better. I’m also used to that because most multi-rail PSU have a low maximum load on single rails. Not in this case. The Platimax D.F. has two +12V rails rated at 25A and two at 35V. That’s a lot for anything you will do. It also helps to balance load and heat inside the PSU.

Below is a picture which is illustrating how all the rails are split. There are two 25A for the motherboard and the CPU and two 35A for graphics cards and additional devices. In new computers that additional devices are usually limited to single SSD so the load is not significant and we can use graphics cards without special limits.

The PSU offers universal AC line input so can automatically adjust the AC voltage between 100 and 240V. We will test it at typical for EU 220-230V AC.

The Platimax D.F. comes in a quite large box for a PSU. The exterior is well designed and has all the info we need to know about the product inside. On the back of the box is the more detailed description and the tables with cables length and other specifications.

Inside the box is everything required for PSU installation. We can find whole cable set, cable strips, power cord, user’s manual, cable pouch and of course the PSU.

The first thing which is just hard to miss is how great the PSU looks. Black paint coating is quite unique, resistant to scratches and simply looks interesting. Fan grill is black-chrome what perfectly fits the whole design. We can see something similar in a couple of competitive products but always in top PSU series which aren’t cheap.

The PSU is also compact. Length is only 160mm what isn’t much considering how much power it can deliver. What is interesting, all models up to 1200W have the same size.

As its name suggests, the Platinum D.F. is an 80+ Platinum class PSU with the expected efficiency of at least 89-93%.

From additional things worth to mention is retention clip which is holding the power cord so we won’t pull it out by accident. We can see it almost only in professional solutions like servers.

There are also cable management clips. There are a lot of them and are really handy. It’s not hard to notice that a big bag of these clips isn’t cheap in stores. There are way more than we may need or at least more than I needed for the PC build using the Platimax D.F.

All the cables look great. Once again we can see the high quality and unique design. Every single cable is individually sleeved and perfectly matches whole PSU design.

Interior of the PSU looks clean. Soldering is high quality on all boards. Not so many additional heatsinks suggest there were no issues with cooling the components.

Everything is quite tight because of the small size of the PSU itself but the airflow is still good. During the tests, the PSU was quiet and didn’t require full fan speed even during high load.

The first things that we see are two large Nichicon caps rated at 400V, 330uF and 390uF. Both rated up to 105°C during constant work. Enermax claims that all caps in this PSU are Japanese and actually I can’t see any others. All other caps are also rated at 105°C.

The used fan is ED142512W-FA rated for 12V 0.10A. It’s a 140mm fan, made in Twister-Bearing technology. There is also Dust-Free technology which helps to keep our PSU clean. Manual switch to activate Dust-Free mode is on the back of the PSU.

What is interesting, the fan is rated at 160,000 hours MTBF. It’s really long for any type of fans. One more strong point so Enermax don’t have to worry about returns during the 5-year warranty period.
