GIGABYTE is a corporation famend for its in depth vary of motherboards and graphics playing cards, myriads of which handed via our checking out labs. Regardless, the huge volumes at which GIGABYTE is generating motherboards and graphics playing cards has no longer stay the corporate from making diversification efforts in opposition to just about each section of the PC marketplace, starting from laptops and mini PCs to gaming keyboards and chairs.
GIGABYTE isn’t a stranger within the energy and cooling industry, shyly advertising and marketing their first few PC PSUs over fifteen years in the past. The corporate’s PSU releases have been few and some distance between, with GIGABYTE grabbing a bit piece of the marketplace percentage however by no means making an important effort to crush the contest.
In nowadays’s assessment, we’re taking a look on the GIGABYTE UD1000GM PG5, an impressive 80Plus Gold qualified PC PSU. What makes the UD1000GM PG5 stick out from the gang is the brand new 12+4 pin connector (12VHPWR connector), which is needed by means of the ATX 3.0 same old. GIGABYTE does no longer declare that the UD1000GM PG5 is ATX 3.0 compliant, however having the 12VHPWR connector lets in for partial compatibility – and conceivably future-proofs the PSU towards upcoming graphics card releases.

Packaging and Package
GIGABYTE provides the UD1000GM PG5 in an aesthetically fascinating however slightly small cardboard field, hinting on the compact dimensions of the PSU in the case of its energy output. Throughout the field, the PSU is encased inside of skinny packaging foam that provides partial coverage from delivery injury.
There are just about no pieces bundled along with the UD1000GM PG5, with GIGABYTE sticking to absolutely the fundamentals. Best 4 standard mounting screws and an AC energy cable can also be discovered within the packaging.
The GIGABYTE UD1000GM PG5 1000W PSU is a completely modular design, taking into consideration the removing of each DC energy cable, together with the 24-pin ATX connector. Lots of the cables are naked, ribbon-like, with black wires and black connectors. The one exception is the brand new PCIe 5.0 cable this is manufactured from black wires and has black connectors but additionally has black sleeving protecting it.

The brand new PCIe 5.0 cable is the spotlight of this PSU. This connector is needed by means of the brand new ATX 3.0 same old for any PC PSU that has an output more than 450 Watts. In fact, the connector by myself does no longer make the UD1000GM PG5 ATX 3.0 compliant, as the brand new same old brings a lot of and demanding adjustments to the marketplace. Alternatively, it will assist the UD1000GM PG5 to last more.
Bodily, those 16-pin connectors aren’t considerably higher than legacy 6/8-pin PCIe connectors, however they function twelve pins plus 4 sensing pins. Out of the 4 sensing pins, two are necessary and two are non-compulsory. The necessary pins sign to the PCIe card the utmost energy that the connector can maintain, permitting the cardboard to keep watch over its energy draw. That makes using adapters on older PSUs difficult, as there is not any approach for the PSU to sign the cardboard and their cables can’t maintain a excessive present draw, so the preset output can’t be any place close to 600 Watts. The one window for safely the usage of adapters limits a passive adapter’s output to the minimal allowed by means of the brand new same old (150 Watts) or would require energetic adapters with a couple of legacy connector inputs.
Those new 12VHPWR connectors can ship as much as 600 Watts every. Relying at the PSU’s capacity, the utmost wattage that it can give is imprinted on the connector itself. The connector of the UD1000GM PG5 states that it may well maintain 600 Watts steady, which is the utmost dictated by means of the ATX 3.0 same old.

Exterior Look
The GIGABYTE UD1000GM PG5 PSU may be very compact for a 1 kW unit. Measuring simply 86 mm × 150 mm × 140 mm (H × W × D), the UD1000GM PG5 manages to completely agree to ATX same old dimensional specs, making it appropriate with just about any ATX-compliant case. The metal chassis is sprayed with a satin black paint and a number of other portions of it had been embossed to create a futuristic design. The fan’s finger guard additionally is a part of the chassis itself.
GIGABYTE moved the decal with the unit’s certifications and specs on the most sensible of the chassis, leaving the perimeters to function an inventive design. The decal is going through sideways, with the dressmaker obviously pondering that this orientation would make studying it from a windowed facet panel more straightforward.
A regular on/off transfer can also be noticed on the rear facet of the unit, beside the facility connector. There’s proof {that a} decal was once (or must had been) proper underneath the facility connector however we discovered not anything there. Lots of the entrance facet is roofed by means of the connectors for the modular cables, with GIGABYTE strongly insisting that customers must use simplest the equipped cables for this PSU.
Inside Design
GIGABYTE entrusted the cooling of the UD1200GM PG5 to Jamicon, a sister corporate of the better-known Teapo. The Taiwanese fan producer isn’t well-liked among PSU designers however their merchandise are thought to be to be of above-average high quality. The KF1225H1H 120 mm fan within the UD1200GM PG5 is a slightly fundamental type, with a rifle-bearing engine. This fan looks like an unusual selection for a PSU with a 10-year lengthy guaranty and will incite a large number of RMA requests after that a few years.
Each the OEM and the platform of the GIGABYTE UD1200GM PG5 are totally new to us. GIGABYTE entrusted the producing of this PSU to Xiamen Metrotec Digital Trade Co (or MEIC), a Chinese language OEM whose merchandise we’ve got no longer noticed prior to. Having been round since 2007, MEIC isn’t a brand new corporate however they’ve been most commonly energetic with generating smaller merchandise, akin to chargers and gear banks.
The filtering degree of the GIGABYTE UD1200GM PG5 is textbook, with a complete of 4 Y capacitors, two X capacitors, and two filtering inductors resulting in a twin enter rectifying bridge configuration. The bridges are put on a large heatsink. The passive APFC elements are a colossal 400V/1000μF APFC capacitor made by means of Nippon Chemi-Con and an similarly huge filtering coil. The inrush present of this configuration can be horrendous and may end up in circuit breaker tripping if Sort B MCBs or low-rating MCBs are in use. The energetic APFC elements are on a protracted heatsink proper around the fringe of the PCB.
Two transistors shape a regular half-bridge inversion topology on the number one facet of the unit, whilst six MOSFETs generate the 12V line on the secondary facet of the transformer. The three.3V and 5V traces are generated by means of the DC-to-DC conversion circuits. It is a very standard configuration for an 80Plus Gold qualified unit. All the secondary capacitors, electrolytic and polymer alike, are equipped by means of Teapo and Lelon, each Taiwanese producers. Teapo is a producer we regularly see the goods of in mid-tier merchandise. Lelon isn’t as referred to as Teapo however their merchandise are of about equivalent high quality. Regardless, fanatics would almost certainly hope to seek out one thing higher inside of a high-tier PSU with any such lengthy guaranty.
