Trying out the ProLab Design XPOWER XP-750 PSU: A Fabulous Midrange Offering

Reviewed by Rounak Roy

Introduction

ProLab Design is a recently established manufacturer of premium computer components. A network of professionals from fields including developers, medical and bioscience, AI and big data science, and content creators (videographers, photographers, editors, and composers) joined hands to make the ProLab Design brand successful.

Professional Computer Hardware, such as Cabinets (Mid-Tower, Full-Tower, Super-Tower, Rackmounts, Workstation Cases, and more), Coolers (AIO Coolers & Air Coolers for HEDT CPUs), PSUs (ATX 3.1, PCIe 5.1 Compliant, 80+Gold or Platinum, and Cybernetics Certified), and in the future Professional Esports Grade Peripherals, are all part of the brand's mission to offer the best possible price-to-performance ratio.

We are grateful to ProLab Design for providing us with the review sample. All views on the following review are our own.

General Overview

ProLab's new XPOWER PSU series includes the mid-range XP-750 a ATX 3.1 and PCIe 5.1 compliant power supply, which offers excellent overall performance and silent operation.

At ₹7500 (about $87), it is reasonably priced for the quality and functionality it provides. It is a full modular unit offering an 80 Plus Gold rating at around 92% efficiency at 50% system load. Along with the high efficiency is the DC-DC voltage control for optimal performance and efficiency, the XP-750 has Japanese-brand capacitors on both the primary and secondary sides. It uses a FDB Fan from BOK Model: BDU12025S and has a Digital fan control circuit which ensures ample cooling for the PSU thanks to the semi-passive fan profile.

Packaging And Accessories

The PSU is nicely wrapped in a black and white cardboard box with the ATX 3.1, PCIE5.1, and 80+ badges on the front, as well as the brand's logo and key features. Its sides display the primary specs, while its back and sides display the importer and regulatory information and fan profile characteristics, respectively. We see that the PSU is wrapped in foam to prevent damage during transport, and the cables and four mounting screws are neatly packed in a zip-lock bag when we open the box.

Design Overview

The PSU's external appearance is attractive, and its proportions are modest. A power switch is located on the front side, next to the AC outlet. Eleven connections, including one 12V-2×6 socket, are located around the rear of the modular board. A label containing the PSU's power rail characteristics, brand name, and certification and regulatory details are located on top. A fan grille with a flowery motif that matches the PSU body is located on the bottom. With dimensions of just 14 cm by 15 cm by 8.6 cm, the PSU is rather small overall and provides enough of space for cable tucking erm I mean cable management 😉. And since the cables are all flat they are quite bendy and can be easily routed along the body of the cabinet for a cleaner overall look which cables with nylon sheathing on the outside can’t.

Internal Overview and Testing Process

The PCB is compact and densely populated. The heatsinks are sufficiently large to provide adequate passive cooling for the components. The design of this platform is DC-DC. There are a few vertical and horizontal boards visible within. The input transient filter is located on the board next to the mains socket. The DC-DC converters that produce the smaller rails are located on the one of the other boards, while the 12V circuitry is on the third.

Capacitors from Toshin Kogyo Co. Ltd., a respectable Japanese capacitor manufacturer, are used in the PSU. The temperature threshold of the 400V 550uF primary bulk capacitor is as high as 105C. The secondary's smaller capacitors have the same 105C rating and are rated for 16V 3300uF. The PSU can thus, in my opinion, readily manage systems with a high enough load with good enough efficiency.

Test System Specs:

AMD Ryzen 5700X
Gigabyte Aorus B550 Elite V2
Nvidia RTX 3080
TridentZ Royal 3600Mhz 16x2
1x 1Tb Nvme, 1x500Gb Nvme
6x Fans

Total System Power Consumed was around 550 Watts. I tested the total power draw using a wireless Watt Meter.

The voltages were observed in HWInfo64, they were stable and in the acceptable range. Below are the voltages as observed by me

At 5-10% load the voltages were as follows:

12V@ 12.11V
5VDC@ 5.02V
3.3V@ 3.31V
5VSB@ 4.99V

At Full load of ~550 Watts the voltages were as follows:

12V@ 11.99V
5VDC@ 4.99V
3.3V@ 3.297V
5VSB@ 4.94V

Looking at the voltages I can say that the PSU performed pretty well and the voltages were well inside the tolerable range.

Conclusion

However, there was a hiccup I faced. The connectors on the PSU side especially the 20+4pin was way too tight. New users may find it unnerving because the connectors may also resist a little when they plug into the PSU. Despite this small problem, the XP-750's performance under demanding loads surprised me. A key consideration in my view was the fan's quiet efficiency, as evidenced by the fact that it is rarely heard. Additionally, the power output did not throttle or become unstable during the strenuous tasks I used to evaluate my system, such as gaming and synthetic benchmarks.

Bottom Line

In summary, a solid combination of performance, compatibility, energy efficiency, and safety are provided by the ProLab Design XP-750 power supply. Although there are a few problems with tight modular connectors, the overall dependability and efficacy of the power supply outweigh this disadvantage. I have more faith in the XP-750 as a crucial component of my computer setup because of the 5-year guarantee. I'll give the PSU a strong Tech Reprise Gold Badge of Honour and a score of 9 out of 10.
