The Cooler Master X Silent MAX 1300W is a powerful PSU, promising for dead silent operation. Internally it is similar to the passive Silent 1100W unit, but it lacks the advanced cooling system with the heatpipes, since it has a cooling fan.
The Cooler Master X Silent Edge 1100W will be included in my best ATX v3.x & PCIe 5.x PSU picks article.
I have already evaluated the X Silent Edge 1100W, which, in general, left a good impression on me, so it is high time now to look at the strongest member of the line, which can deliver up to 1300W but it has active cooling, to do so.
Like the passive mode, the 1300W unit uses an in-house platform, and according to CM, everything is made by its production lines, including the chassis, all relevant cooling parts, and the PCB. Both units use the same platform, with the only difference being the lack of heat pipe cooling on the 1300W model since it has a quality cooling fan to compensate for this loss. The loss of heatpipe cooling lowers production costs; hence, Silent Max has a lower price tag than Silent Edge.

“A lower ripple at 12V under full load would be highly welcome, but I want a better transient response on this rail at high loads. To achieve this, more capacitance is required, and polymer caps don’t cut it there, so you need to use electrolytic ones, which are not as tolerant to high temperatures. Given that CM wants to keep the fan’s speed low, this could lead to problems. This is a design challenge that CM’s engineers have to handle.”
Why does CM have to do this? Perhaps you should demand that the standards be more strict, as this unit meets them, correct? If the transient response fails the standard then I can understand the demand. Otherwise, it’s an aspiration until some other company comes out with a PSU that is this quiet with this high a wattage.
I don’t agree with the warranty criticism. It is stated definitively without proof:
“Such a long warranty period will eventually create problems for both the brand and consumers”
Will? How about “might”? It’s actually refreshing to see a company stand behind their product. 15 years is not an unreasonable lifespan for a PSU.
The price of $459 MSRP (inc. VAT) is just too much for most PC builders; at least the Cooler Master X Silent MAX Platinum 1300 has a 6% deviation in 200% load ATX v3.1 transient response tests. Unfortunately, the transient response is not good at 120/160/180% load tests, and the ripple suppression is not very impressive on the 12V rail (full/100% load), especially when considering the high price.
On the other hand, the XPG CyberCore II 1300 and Seasonic Prime TX-1300 are still the best-performing 1300W PSUs in the ATX v3.1 transient response test (200% load) on the 12V rail.
The problem with the Seasonic Prime TX-1300 (€ 425) is its ridicolous price in the EU when compared to the XPG CyberCore II 1300 (€ 230).
Not my choice for a 1300W PSU.
Silence costs money.
In this price range one can get a seasonic 1000-1300W model and never look back.
Disagree with Seasonic. In 2021-2022 i remember quiet a few articles on techpowerup, tom’s hardware, reddit etc about issues with their PSU (and bad warranty service). Be careful with these brands like Noctua promising eternity* We have seen recently Asus, EK…
Seasonic prime is the only power supply I’ve had problems with, first it would turn on occasionally then it even stopped turning on. And I’m not the only one. The CWT platforms are much more reliable
This coolermaster psu is an excellent unit. You would be silly to not give it a solid consideration when it comes time to purchase.
You’re kidding me for $459 MSRP?
Not affordable
Protection features need tuning for larger differences in the triggering points (12V OCP & OPP) between hot and cold conditions
12V rail’s transient response needs to get better in ATX v3.1 test scenarios
Efficiency needs boosting at light loads
The 3.3V rail needs tighter load regulation
Increased vampire power
Ideally, it should have an IEC C20 input/socket
Such an extended warranty period will eventually create problems for both the brand and consumers
It seems reasonable to me, considering how quiet it is and because the warranty is so long.
I’d rather pay more for quality versus less for something that won’t last as long and which increases noise pollution.
