Zalman ZM600-HP 600W Power Supply Review

Zalman ZM600-HP 600W Power Supply

The Zalman ZM600-HP power supply is an awesome power supply. Our voltage stability test results show that it is really capable of maintaining a very stable voltage, even under heavy loads. We do have a few dislikes here and there, but they are nothing compared to its stability and silence

We are not very happy with the capacitors used in this power supply though. Although it was produced by Fortron, Zalman should have insisted on better quality capacitors. After all, Corsair upgraded the capacitors on their HX PSUs, which are also OEM PSUs.

With that said, and in spite of the capacitors used, this is still a very good PSU. Although the rails are not as well calibrated as PSUs from PC Power & Cooling, Enermax or Zippy, they are really stable and that is still something to behold. You don't see this kind of performance from el cheapo power supplies.

Of course, there are things that Zalman can improve on in future models. For example, spreading out the fins on the heatpipe cooler and upgrading the capacitors. But as it is right now, the Zalman ZM600-HP is one silent and steady beast. Even if you can get a Seasonic S12 at the same price, I'd still recommend this Zalman PSU instead.

With a price tag of around $120, this may be pricier than other 600W power supplies, but if you are looking for a quiet and powerful solution, this is a power supply you should consider.

In addition to providing four 12V rails that can give you a total current draw of 42A, this power supply also comes with a heatpipe-based cooler with a large, quiet 120mm fan. It also boasts an efficiency of 84% and a power factor of 99% with active PFC.

The ZM600-HP also comes with a modular cable system for non-essential power cables. All the cables, both fixed and modular, are rounded and sleeved. This is great because it improves air circulation as well as allow you to customize and manage the cables for a neater system.

You can get a 600W power supply for less, but it's unlikely that you will be able to find them equipped with all those features. Its quiet and very stable performance will especially be hard to beat.

* Our New Review System

ARP is committed to developing new ways to improve your experience with us. As part of our continuous efforts to improve the value of our reviews to you, we are implementing a new review system.

This new review system is designed to allow you to quickly receive information on the latest hardware. This new system also allows you to quickly get the gist of the review without reading through it. This can be very useful, especially in situations where you need to make a quick purchase decision.

In this new system, we start with a Product Overview whenever a company sends us a press release about their latest product. We shift through extraneous PR-talk to create a straightforward summary of the product's features as well as specifications. This allows you to quickly find out all the pertinent details about the product, without reading through official press releases.

When we receive the product for review, we will quickly take photos of it and create a Pictorial Review. The purpose of a pictorial review is to allow you, the reader, to quickly examine the product visually. It may help you make better purchase decisions, especially if you cannot wait for the full review.

After thorough testing, we will post a Comprehensive Review of the product. This adds on to the pictorial review with comprehensive test results and our final conclusion on the product.

But no matter whether you are reading a Pictorial Review or a Comprehensive Review, you can always read the summary of the review as well as examine the product's specifications right on the first page. In all our new reviews, we will maintain the first page as a Product Overview page. If the product is listed in PriceGrabber, you can also check out the lowest price online.

We hope this new review system will make your experience a lot more enjoyable and informative!
