The Yeyian Gaming Pegasus 1000W is an ATX form factor power supply which for sizing means that we know it will be 3.3 inches tall and 5.9 inches wide. The big variable with power supplies comes down to their length and the Pegasus 1000W is 6.3 inches long. It isn’t a true squared-off design with the length matching the width but it isn’t too far off which isn’t bad for a 1000-watt power supply. It is ATX 3.0 compatible with a 12VHPWR cable connection and it is 80 Plus Platinum rated. I had a little trouble finding its testing on the 80 Plus website initially because Yeyian and Pegasus didn’t come up but I did find it under its model name, if you want to check out the testing you can see it HERE. There is one big thing to note, this was tested in 2016 and we know that 12VHPWR just came out, so it does look like they have updated the design slightly. Assuming there aren’t any changes to the internal design, it would still be 80 Plus Platinum as listed, on the packaging, and on the website but the specifications on the website do list it as an 80 Plus Gold for some reason. The design has an all-black housing with a large fan opening that is filled with a grill with hexagram cutouts across it and the Yeyian branding on the center. It has a 140 mm fan that is black to match everything else to help keep things cool.
The top of the Pegasus 1000W is completely flat without anything going on. It does give us a better look at the overall finish which has a slight texture and is surprisingly glossy once under the lights. Our Pegasus 1000W did come with a scratch in it in the corner as you can see. It doesn’t affect performance at all and is hidden away on this side but depending on your case configuration this could be facing up and visible.
Both sides of the Pegasus 1000W have sets of square holes running along the bottom edge which add a little more ventilation. One side has the Yeyian logo stamped into the steel housing and the other has a sticker that covers the entire side. The sticker side is flipped upside down so it will be readable when the Pegasus 1000W is installed with the fan facing up whereas the stamped logo is the other way for when you have it installed with the fan facing down which is more common. The sticker has the Yeyian branding as well as the Pegasus 1000W model name. Then it has a breakdown of the wattages by voltage and has all of the normal required logos and warnings as well.
The inside-facing end of the Pegasus 1000W is where you will find the modular cable connections, no surprises there. It does also have a white sticker which has the serial number and a barcode on it. For connections, there are two rows. The top row has two larger plugs for the motherboard 24-pin which has 28 pins on this end. 18 of those are on the first plug and 10 are on the second smaller plug. Next to that are two 8-pin connections which can be used for the PCIe cables or the CPU power cables. The bottom has four peripheral cable connections on the left with 6 pins each. Then there are two more of the PCIe or CPU power 8-pin plugs. Then at the end of the bottom row on the right is the one 12VHPWR connection. All of the connections have legends printed under them in white but the 12VHPWR is just included with the PCIe/CPU connections and not labeled at all, not that you will accidentally plug anything else into it.
The outside end of the Pegasus 1000W is mostly covered in hexagon-shaped holes which help vent the air pulled in from the fan side out the back of your case. This side does have the C14 power plug inlet and above that a power switch.
The cable box comes with all of the modular cables wrapped up individually. There isn’t an extra storage bag but the box itself can do that. Our box however was already coming apart, so long term it may not hold up. Along with the cables it also has a bag with four black mounting screws and four black zip ties. The power cable is also in the box which is your standard C13 to NEMA 5-15 cable, aka your normal PC power cable.
For cables, the Yeyian Gaming Pegasus 1000W has ten cables in total with all but one of those having the flat cable design with a black finish. The last cable is sleeved with a black sleeving keeping everything in line with the Pegasus’s all-black finish. The 24-pin motherboard power is the sleeved cable and it comes in just past the 24-inch mark for length. There are also two PCU power cables which are both the same length at 29 inches. For powering video cards, the Pegasus 1000W has three different cables. There are two PCIe cables which have splittable 6+2 cables daisy chained at the end of both cables for four 8-pin PCIe connections in total. The first connection is at 25 inches and the second is 5 inches past that. There is also a new 12VHPWR cable which is 25 inches long. Every 12VHPWR cable that I have seen so far has been sleeved but this one isn’t it has the same flat cabling as the other cables. The 12VHPWR cable does have a 600-watt rating printed on it, it is hardly visible but there. Then for the peripheral cables, there are four in total, each having three connections on them at the same locations. The first plug is at 19 inches, the second is at 25 inches, and the last is at 30 inches. Three of those cables are all SATA power and then there is one Molex. With just three connections each these have a smaller gauge wire from what I can tell, the cables are extremely flexible and thin.
