MWE Gold 1250 V2 ATX 3.1 Power Supply Level Up Power
The MWE Gold 1250 V2 (Fully Modular) ATX 3.1 PSU is an upgrade of the ATX 3.0 variant with improved ATX 3.1 support and an enhanced PCI 5.1 12VHPWR cable with 90-degree connector for graphics cards.
Reliable Under Pressure
An increased safe-operating temperature threshold (0 – 50 degrees Celsius) makes extreme graphics settings far more reliable in terms of output stability.
80 PLUS GOLD EFFICIENCY
MWE Gold V2 ATX 3.1 power supplies feature an 80 PLUS Gold efficiency rating with up to 90% efficiency (under typical loading), which makes it the perfect solution for power-hungry setups.
FULLY MODULAR CABLING
Complete cable management enables sophisticated case build aesthetics and improves internal ventilation by eliminating unnecessary cabling.
ATX 3.1 SUPPORT
MWE Gold V2 ATX 3.1 power supplies are compliant with ATX 3.1 and can fully support peak power drawn by the latest graphic cards.
140MM FDB FAN
A 140mm Fluid Dynamic Bearing (FDB) fan delivers long-lasting, quiet and effective cooling (MTBF >100,000 hours).
Smart Thermal Control Mode keeps the fan turned off while the PSU draws <40% of rated output power (zero-RPM mode).
PCIE 5.1 12VHPWR CONNECTOR
An upgraded PCIe 5.1 design with a 90-degree connector improves overall electrical durability, reduces heat gain, and improves plug-in integrity.
HIGH TEMPERATURE RESILIENCE
A superior 50°C maximum operating temperature allows most systems to push limits when overclocking or other high-intensity applications.
FLAT BLACK CABLES
Includes the following cables: ATX 24 Pin x 1, EPS 4+4 Pin x 1, EPS 8-Pin x 1, SATA x 12, PCI-e 6+2 x 3, Peripheral 4-Pin x 4, & PCIe 5.1 12VHPWR x 1

80 PLUS GOLD – 90% efficiency (under typical loading) makes 80 PLUS Gold ideal for PC gaming systems with high energy demands – saving on utility costs and improving overall performance by reducing heat accumulated through inefficient energy conversion
ATX 3.1 COMPATIBLE & FULLY MODULAR – Fully compliant with ATX 3.1 standard & PCIe 5.1 12VHPWR 90-degree connector; Complete cable management enables sophisticated case build aesthetics and improves internal ventilation
HIGH-TEMPERATURE RESILIENCE – MWE Gold V2 PSUs feature a higher temperature threshold of 50°C making it a wise choice for overclocking or real-time/in-game 3D rendering on powerful GPU’s or dedicated graphics cards
140MM FDB FAN – The 140mm fluid dynamic bearing (FDB) fan features smart thermal control mode with temperature-responsive fan-speed control and zero-RPM mode; This results in the PSU drawing less than 40% of rated output power thereby reducing noise

Customers say
Customers find the power supply unit works well with their PCs and appreciate its quiet operation, good value, and ease of installation. The cable quality receives mixed feedback – while it comes with plenty of modular cables, customers note it only includes three PCIe cables. The power supply’s reliability is also mixed, with some finding it reliable while others report it failing within five months.

Very good!
Perfect cable length, with more to cable manage! Compatible with all ATX motherboards. Doesnt make a sound, while staying cool, even looks stylish in a PSU basement! and the install, it was super easy! Suggestion to people swapping, put the cables in first BEFORE screwing it in.

yeh comes as shown
very fast 1 day delivery from this specific seller now granted it might be because I’m in south London but so far the packaging shows that its brand new and working correctly, if somewhat found a problem 3 months in then ill update the comment. Also it only gives 4 x 8pin connector so if ur graphics card needs 3 x 4 pin connector like for example rtx4090 then you’ll need to purchase an extra one or if ur not planning to overclock ur cpu then give up 1 x 4 pin from the cpu power for gpu. 07/30/24So update 8 months later, after absolutely putting gpu and cpu power to max without overclocking anything and having to pay more bill cuz increased power usage. I’d say its a very well made and affordable power supply. So far there’s 0 problems whatsoever with it and i just love the modularity of it cuz if i need hdd then i can just plug in the sata power but if no then i can take it off to reduce clutter.

Build quality is much better than old PSU. Good packaging. Easy to install. Beware of its size.
Delivery was on time. Did not expect it to be Royal Mail. Also did not expect to be charged £1.50 before my FREE delivery package was handed over?!?No external packaging at all. Not so much of a problem as Cooler Master box was quite robust. Easy assembly. Cables are long enough for an average size case. Did require a bit of a case mod due to the large size of this PSU. Smaller dual chamber case owners beware.Whisper quiet and far more efficient than the previous non branded PSU the build came with.Overall very pleased with this upgrade.

Does the job just fine
Does the job it’s supposed to, bit of a tight fit in my relatively small PC case. My only gripe (and it’s a very minor one) is about the cables that are included. They work fine, decent quality, and there are plenty of them, but, they are a bit bulky and awkward to route tidily. Probably less of a problem if you have more space between your motherboard and the outside panel of the case.

Does what it says on the box
The Cooler Master MWE 850 Gold V2 is a great power supply. It’s got plenty of modular cables, so you can keep your build clean and tidy. Plus, it’s powerful enough to handle even the most demanding setups. If you’re looking for a reliable and efficient power supply, this is a great option.

great price for a 750W gold PSU
This has been well reviewed and recommended by Tom’s hardware and at the £77 I paid for it in late 2022 was a great PSU at a great price. I see now that it’s well over £100 thanks to what looks suspiciously like price gouging – I don’t buy “inflation” – inflation is not 50%. At that price you are starting to get into the realms of a Bequiet Pure Power 12 which is probably a better PSU.Doesn’t have a million cables and you may well end up using all of them but if you don’t have any SATA devices it saves you some cabling. I bought 2 of these last year for gaming computers for my niece and nephew and both are still going strong and their computers are on all day every day – beyond that i can’t say much other than so far it’s working well and is nice and quiet.

Bad product, bad service, or both?
Purchased one a few days ago, got around to installing to find that it doesn’t work, just makes a clunking noise when trying to power on. Thought I’d start a return and purchase another of the same. Just turned up and it’s not new, even though I purchased new, all the cables are loose, as are the screws, and 1 of those is missing! I’m not putting a used PSU in my PC. Customer services were pretty crap to be honest and said I was making this return hard for the both of us, because I tried to explain my frustration of having 2 of the same products at sup par quality in 3 days!

J’espère que COOLER MASTER regarde les commentaires sur leur produits ; ont ils essayés de faire du cable management avec des cable PLATS ???C’est une punition inutile. Ou est lâintérêt ou ???POURQUOI ajouter du difficile au compliqué POURQUOI ???A 200 euros l’alimentation je suis obligé de commander des cables RONDS pour faire un montage PROPRE.Ca mériterai de préférer une autre marque, vraiment. 🙁
