msi mpg a1000g pcie5, review and analysis in spanish

After analyzing the original version last year, today we have the review of the MSI MPG A1000G PCIE5. It is a power supply focused on high-end equipment that includes as a novelty the 12VHPWR connector as its name seems to presage. In addition, it maintains the certificate of efficiency 80 Plus Gold and his fully modular cablingas well as the modern desEsports Extrasof the original.


Before you start your review, thank you MSI for sending us this power supply for review.

Packaging and Accessories

front packaging

We begin the review of the MSI MPG A1000G PCIE5 checking how it comes in a black cardboard box with purple details that changes the classic gaming aesthetic of the brand for a more sober and elegant one.

rear packing

On the back, we find information on its main features and wiring, while inside we find the power supply very well protected by a foam frame and, next to it, a cloth bag that contains all the wiring.

In addition to the cloth bag, a notice is included that we must insert the 12VHPWR connector all the way, as well as the European regulation certificate.

MSI MPG A1000G PCIE5 - Modular Cabling

Already inside this, we find the following completely modular wiring, as well as the installation screws and the power cable.

  • 1 ATX cable (24+4 pin) [60cm]
  • 2 ATX/EPS cables (4+4 pin) [70 cm]
  • 1 600W 12VHPWR cable [60 cm]
  • 1 cable x 2 PCIe connectors (6+2 pin) [60 cm]
  • 2 cables x 2 PCIe connectors (6+2 pin) [60 + 15 cm]
  • 4 cables x 4 SATA connectors [50 + 15 + 15 + 15cm]
  • 1 cable x 4 Molex + Floppy connectors [50 + 15 + 15 + 15 + 15 cm]

DesEsports Extrasand features of the MSI MPG A1000G PCIE5

MSI MPG A1000G PCIE5 - Design

We continue the review of the MSI MPG A1000G PCIE5 once we free it from all its packaging. Before us we have a power supply of ATX-format with dimensions of 150 x 86 x 150mm (width, height, depth). It is therefore quite compact for its power, since most models tend to increase its depth in these powers.


With a grille with a modern and striking design, we find a fan 135mm which has semi passive function, that is to say, that the fan remains off up to 400W of power load so that the noise is zero. If we leave it off, the fan spins at about 450 RPM up to 500W of power, being equally inaudible in practice.

MSI MPG A1000G PCIE5 - Power connector and Zero Fan button

We achieve this on the external side of the power supply with the zero fan switch additional connector that is located next to the power connector, as well as the power connector C21.

MSI MPG A1000G PCIE5 - Rails

On the opposite side of the fan, we find the usual rail distribution sticker. This shows us how the power supply MSI MPG A1000G PCIE5 dispose of 1 +12V rail of 83.5 amps. In this way, it can deliver up to 1000W of continuous power on the +12V rail, although we must disconnect what is consumed on the rest of the rails. Of course, it promises to offer a 2000W peak power for 100 µssomething necessary to fulfill the certified ATX3.0 and PCIe 5.0.

The MSI logo is clearly visible on both sides of the power supply, being inverted on one of them so that it looks good when having the source in the lower part of the chassis.

MSI MPG A1000G PCIE5 - Modular Connectors

It is on the internal side where we find the connectors for the modular wiring, highlighting the 12VHPWR connector as a great novelty compared to the original model.

Interior and Components

MSI MPG A1000G PCIE5 135mm Fan

The next step in the review of the MSI MPG A1000G PCIE5 to access its interior to take a look at its components. First, we meet your fan Hong Hua HA13525H12SF-Z of 135mma classic in power supplies with bearings fluid dynamic which works perfectly.

MSI MPG A1000G PCIE5 - Internal view

Another classic of OEM power supply manufacturing is C.W.T., in charge of the manufacture of this model following the same desEsports Extrasas in the original model. Therefore, it uses a platform with typology Half Bridge LLC and one conversion DC/DC for the 3.3V and 5V rails.

MSI MPG A1000G PCIE5 - Main Capacitor

In addition, we must highlight the exclusive use of 105º Japanese condensers, with a main condenser Nippon Chemi Con of 400V and 820 μF. Nor should we forget to note that it has electric protections that its circuitry offers against excess power/voltage/current/temperature, lack of voltage and short circuit, the usual ones in any modern power supply.

test equipment

test equipment

For the review of the MSI MPG A1000G PCIE5we have assembled the following test equipment:

  • Thermaltake Core P3 TG Pro Chassis
  • MSI MEG Z690 Unify Motherboard
  • Intel Core i9-12900K processor
  • MSI MEG CoreLiquid S360 Liquid Cooling
  • G.SKILL Trident Z5 RGB Memory @ 5600 MHz
  • Nvidia GeForce RTX 3080 Ti graphics card
  • Windows 11 Pro Operating System

MSI MPG A1000G PCIE5 benchmarks

MSI MPG A1000G PCIE5 - Tests

During our tests, we have verified how when turning on the equipment, with the semi-passive mode active, the fan remains off even with the equipment demanding power from the processor. It’s not until we play or squeeze the graphics card that its fan starts to spin smoothly, being really inaudible with the noise of the GPU fans and liquid cooling.


We have analyzed with Aida64 Engineer the stability of the voltages for the +12V, +5V and +3.3V rails by testing the stability of all components, with or without GPU. In this way, we see how the voltages remain very stable both with the equipment at rest and at full capacity, something that helps to achieve a very tight consumption of 704W for the complete team at maximum performance. It is a value within what is expected for a power supply with the 80 Plus Gold certified as we can see in the following comparative graph against other models already analyzed.



MSI MPG A1000G PCIE5 - 3/4 Design

We conclude the review of the MSI MPG A1000G PCIE5 highlighting that this is an ideal power supply for fans of the brand who want to complete a complete team within the MSI ecosystem. In fact, we will not be able to have a processor or MSI memories, but the rest of the components and peripherals can be from the brand, since it is one of the ones that offers the most variety.

Focusing on what the MPG A1000G PCIE5, we must emphasize that this is a very good power supply with a very stable and adjusted power delivery. This is how you get the certificate efficiency 80 Plus Gold, even if it is the minimum required for a new batch model. It also highlights the semi passive function of your fan and his fully modular cablingwhich includes as a novelty the 12VHPWR connector for NVIDIA RTX 4000 graphics.

Can find it for sale for 199.99 euros in stores like PcComponents, a price similar to that of the original model, which it obviously replaces on the market. However, it is a price similar to that of other models with its features and connections, so it will be especially interesting for, as we have said, fans of the brand.

Main advantages
+ Modern and well finished design
+ Fully modular cabling
+ 12VHPWR connector
+ High stability of all rails
+ 100% Japanese capacitors
+ 80 Plus Gold Certification

+ Very compact, only 150 mm deep
Negative Aspects
nothing to object
Other Aspects
* Available in 750W, 850W and 1000W versions

From The Computer Tinkerer we grant him the Gold Award to power supply MSI MPG A1000G PCIE5.
