Their product catalog includes power supplies (PSUs), computer cases, cooling solutions (liquid and air), mechanical keyboards, and gaming chairs.

Power Supply Units (PSUs)

1st Player is primarily recognized for its extensive range of power supplies, which cater to various market segments from entry-level builds to high-end workstations.

• Certifications: The company has a significant presence in the 80 PLUS certification database, with models ranging from Standard and Bronze to Gold and Platinum efficiency ratings.

• Modern Standards: Their latest product lines, such as the NGDP series, are verified for ATX 3.1 and PCIe 5.1 standards, featuring dedicated 12VHPWR (or 12V-2×6) connectors to support modern high-performance graphics cards.

• Key Product Series:

  • NGDP Series: High-end Gold-certified units, fully modular, often featuring Japanese capacitors and 10-year warranties.

  • Steampunk (SP) Series: Mid-to-high tier Gold-certified units known for high efficiency and modular cabling.

  • DK (Death Knight) & Armor Series: Targeted at mid-range gaming builds, typically holding 80 PLUS Bronze certifications.

  • ACK / Black Sir Series: Entry-level units focused on affordability with 80 PLUS White or Bronze ratings.

Technical Features & Reliability

Feature	Details
Component Quality	Higher-tier models (NGDP, Steampunk) frequently utilize Japanese main capacitors (rated for 105°C) for increased longevity.
Cooling	Units are typically equipped with 120mm or 140mm Hydraulic Bearing (HYB) fans designed for a balance between airflow and low noise levels.
Safety Protections	Most models include standard industrial protections: OVP (Over Voltage), UVP (Under Voltage), OCP (Over Current), OPP (Over Power), and SCP (Short Circuit).
Warranty	Warranty periods vary significantly by tier, ranging from 3 to 5 years for budget series to 10 years for flagship modular Gold units.

1st Player serves as both an independent brand and a manufacturer, often providing a price-to-performance alternative in the global PC market. Their products are independently tested by organizations like Cybenetics and 80 PLUS to verify efficiency and noise level claims.

ACK-650 Bronze PSU

1st Impression

ACK-650 comes with non-modular design and with embossed individual cables instead of the bulked ribbon or sleeved cables, gives a nice aesthetic to it and opens up new doors of freedom with cable manageability. The PSU comes with DC-DC conversion as well as the protections such as OCP, OVP, OTP, UVP, OPP, SCP.

ATX 3.1 Compliance

Refereing to our review of ATX 3.0 and ATX 3.1 standard, ACK-650 complies with more recent ATX 3.1 standard compared to Thermalright TR-TB650S which is ATX 3.0 compliant. This means this PSU is more suited to be used with PC builds having AMD RX 9000 series or Nvidia GeForce blackwell series, providing superior endurance and stability against PCI-E Gen5 spike loads.

Internals

EMI Filter	2-stage
Primary Capacitor	TEAPO LR series 470uF 420V 2000Hrs @105°C
MOV	Present
Secondary Capacitors	TEAPO Electrolytic 3300uF 2000Hrs @105°C
Secondary Side Topology	DC-DC
Rectifier	GBU-1006 – Single

Load testing & observations

Starting with 50% load application, we see very low ripple response, perfectly within ATX standard limitations. The efficiency turns out to be 80+ Bronze compliant at 89%. Regulation held strong troughout the whole range of our testing and didnt fall anywhere below or near-below of the minimum. At 110% load, PSU stayed at respectable 58°C maximum temperature inside which is near half of the rated maximum limit of capacitors. We can safely say that this PSU will last for anywhere between 7-15 years provided a normal use of 8 hours a day under normal gaming loads. The key note here is that the 58°C is observed at 110% load while the real world PC usage load is nearly half of this reference.

Load	Regulation 12V, 5V, 3.3V, 5Vsb	Ripple 12V, 5V, 3.3V, 5Vsb	Efficiency	Temperature Max Inside
50%	12.08V, 4.97V, 3.29V, 4.96	21mV, 8.5mV, 8.5mV, 9.2mV	89%	not measured
100%	12.07V, 4.92V, 3.25V, 4.91V	41.2mV, 8.6mV, 9.0mV, 10.18mV	87.5%	not measured

Checking for maximum power output point

Since this PSU is ATX 3.x certified it doesn’t implement the blocking design where PSU shuts down at loads greater than 110% and hence it continues supplying power. The PSU maintained a nominal output without disturbing its regulation and ripple characteristics till 827W of overpowered Load.

Conclusion

Considering our comparison with market competition, we have more expensive offerings by Corsair as well as XPG namely CX650 and PYLON 650W. This PSU is available in the market at price point of 12.5K PKR while CX650 is being sold at 17K PKR PYLON 650 being retailed at 15K PKR. The later mentioned PSUs are only ATX 2.3 standard compliant and do not confirm the ATX 3.x standard. the ACK-650 Bronze is at a perfect point where it is affordable as well as competitive offer to support even more recent Graphics Card offerings by AMD & Nvidia.

Build Recommendations

ACK-650 Bronze is perfectly viable for mid to upper-mid tier Gaming PC builds featuring GPUs upto RTX 5070Ti and RX 9070 GRE. An ideal system which has power consumption of 350W would be an AMD Ryzen 7 7800X3D / Ryzen 7 9800X3D paired with AMD Radeon RX 9070 GRE GPU. While the entry level PCI-E Gen5 GPUs such as RX 9060 and RTX 5060 will pose absolutely no threat to this PSU.
