Ready for RTX 50 graphics cards: MSI's 850W Gold PSU discounted to under 2,500 CZK

A computer power supply is not a component you want to skimp on – but you can save money on it. The MSI MAG A850GL PCIE5 II now costs 2,429 CZK with code ALZADNY10, and for that price, it offers fully modular cabling, Gold certification, and a native 16-pin connector for current and future graphics cards. Over 2,000 units sold and a return rate of 0.32% speak for themselves.

Quick summary:
✅ Makes sense if you are building or upgrading a gaming PC and want a reliable 850W PSU with support for new graphics cards – at 2,429 CZK, it’s one of the best price/performance ratios on the market.
⚠️ Consider if you have your PC case on your desk and absolute silence is important to you – the PSU does not have a zero-fan mode, the fan always spins.
💡 For 2,429 CZK, you get a Gold PSU with Japanese capacitors, a 16-pin PCIe 5.0 connector, and an extended warranty from MSI.

What you get for the money

The MSI MAG A850GL II is a fully modular PSU – you only connect the cables you actually need, which simplifies building and improves airflow in the case. Its 850 W output with 80 PLUS Gold certification (90% efficiency) will cover even more powerful gaming setups. Inside are Japanese capacitors and DC-DC conversion for stable voltage. Complete protection package: OVP, OCP, OPP, OTP, SCP, and UVP.

A key thing for anyone planning a new graphics card: the PSU has a native 16-pin connector (12V-2×6) according to the ATX 3.1 standard, so it’s ready for GeForce RTX 40 and RTX 50 series cards. In addition, it has 4× PCIe 8-pin for older graphics cards, 2× CPU 8-pin, 8× SATA. Dimensions of 150 × 86 × 140 mm mean it will fit into virtually any ATX case. MSI also offers an extended warranty – after the standard warranty expires, an additional 4 years of free repair at an EU service center upon registration.

What 90 customers say

With a rating of 4.6 out of 5 and 89% recommendation, this is one of the better PSUs on Alza. Users most often praise the price/performance ratio, modular cabling, and compatibility with new graphics cards. One reviewer confirms that the PSU powers an RTX 5070 Ti without issues. Most rate the noise level as acceptable.

Recurring complaints: the PSU does not have a zero-fan mode – the fan spins constantly, even at low load. If you have your PC case on your desk next to the monitor, you will hear it in a quiet environment. The cables are plastic and stiffer, only the GPU cable is braided – which might not look best in a tempered glass case. And the 8-pin GPU connectors are split on one cable, which aesthetically bothers some builders.

Verdict

The MSI MAG A850GL PCIE5 II for 2,429 CZK is a straightforward choice for anyone building or upgrading a gaming PC who doesn’t want to pay an exorbitant price for a PSU. Gold certification, full modularity, native PCIe 5.0 connector, and a return rate of 0.32% – it’s hard to find better specs for two and a half thousand. However, if you are building an ultra-quiet PC and have the case on your desk, consider models with a passive fan mode.
