Great power supply for my gaming and my streaming PCs.
Surprisingly for a PSU that uses custom control chips, probing with an oscilloscope shows no attempt to boost PFC efficiency by gating the PFC drive signals at light load. I guess G2 650 should be even cheaper but for some reason it is not available. Or about as much power as a few indicator LEDs, which is not much. I would have liked to see better efficiency at around the 50-100W region where most modern PCs idle, especially considering they went to the expense of using custom control chips. Cables are done nicely. EVGA RTX 2080 XC Ultra Gaming Video Card Review, CoolerMaster Introduces MasterCase SL600M - Sleek Mid-Tower, Today, July 30th, 2020, Xtreme Performance Gear, a division of Adata, unveiled several new components. On the front are the output connectors, along with the EVGA logo and a warning to not remove the cover. 24″ 6/8 pin GPU + 29″ 6/8 pin GPU No idea what use is a “warranty void if removed” sticker that doesn’t have to be removed to open the case. Compare the main Features, Specifications, Prices and Select the Best Model. Corsair AX1200i or EVGA Supernova P2 1200W or...? Then the 12V is synchronously rectified by 4 MOSFETs and the 5V and 3.3V generated by two voltage regulator cards near the bottom right. I'm looking forward to more PSU reviews here.

This one is super quiet even without using the eco mode. Instead of the full bridge design common in modern PSUs of that power level, it’s a half bridge design that saves a lot of cost and complexity – two fewer transistors and one less gate drive circuit. High quality feel. Read More, There isn’t a whole lot we can say about EVGA that most PC enthusiasts don’t already know. The thing works great and keeps my server running smooth. Love the modular design, warranty and its super quiet. It is very quiet, and so far has not presented any problems at all. Cheap plastic modular connectors, was rather loose in power source.
The cable quality and modular design are phenomenal. Looking more closely at the output side, there’s an electrolytic capacitor crammed right up against the heatsink. Thank you. Included with the cables is an adapter to enable the PSU without a motherboard, something that will come in handy later.
24″ 6/8 pin GPU With the oscilloscope running on batteries to minimize noise and set to a 20MHz bandwidth, we get 7.93mV RMS ripple on 12V, 4.07mV RMS on 5V, and 4.19mV RMS on 3.3V. The ripple readings are excellent, the voltage regulation is unmatched, and the efficiency is pretty good meeting its rated specifications.
The two red-orange film capacitors next to the transformer are what take the ripple current, something they do much better than electrolytic capacitors do.
The half bridge design used to be considered unreliable due to high ripple current through the input capacitors, but rest assured this PSU has done it right. Your email address will not be published. Awesome power supply. I can even go as far as suggesting the 4/8 pin EPS12V cable be permanent as well since it would be highly unlikely for a PC that needs a 650W PSU to not use it. Placement of the modular ports on the PSU makes sense unlike some other brands I've seen.
Works great, looks great! Finally, an XPG PRIME ARBG LED light strip.
(For reasons beyond the scope of this review, the noise floor always increases with more bandwidth. Connectors on PSU seemed delicate, cheap, and flimsy. It has wires for all connections and great quality. Very nice Mike. Even the bottom is not so boring with the EVGA logo again and some stickers. 1080ti (likely FTW3) 750w EVGA SuperNOVA 750 G3, 80 Plus Gold 750W, Fully Modular, Eco Mode with New HDB Fan, 10 Year Warranty, Includes Power ON Self Tester, Compact 150mm Size, Power Supply 220-G3-0750-X1 $129.99 Amazon $119.99 EVGA SuperNOVA 650 G3, 80 Plus Gold 650W, Fully Modular, Eco Mode with New HDB Fan, 7 Year Warranty, Includes Power ON Self Tester, Compact … Inside, we start with a fairly typical arrangement with an active PFC input stage going into a large 400V capacitor, complete with a relay to bypass the precharge NTC for an efficiency boost. Will EVGA be able to deliver on a budget? Let’s see if that still holds true. A substantially better way to do it is to set the board closer to the back so there is less airflow to redirect in the first place, then use a bent piece of plastic that works better for directing airflow. Very nicely built. The information which appears on this site is subject to change at any time. Great connectors. But beyond that, things aren’t so typical anymore. 2 years ago. Very thin power cord. Great connectors. There also appears to be too little thermal grease on the output MOSFETs. The SLI ready is mostly marketing since the provided cables will only accommodate at most 3 GPUs that each only has one power connector while most mid to high-end GPUs have at least 2 power connectors, but it would technically work for a video editing machine that favors multiple lower end GPUs over a single high end one. The fan has EVGA logos embossed onto the blades. So little, in fact, that the TP-Link smart plug I was using initially was not able to detect it and I had to switch to a Mooshimeter to make the measurement. The covered modular cables are fantastic. The low voltage controller board likewise can use a drop of glue to hold it to the nearby transformer. The intent is obviously to direct airflow closer to the center of the board, but it is clearly not a very aerodynamic way to do it.
Seriously, we've gotten to the point where we're pointing out even the most minuscule detail to differentiate one high end unit against the other. We also see that to improve voltage regulation, the voltage sensing is done at the output connector board. Comes with plenty of cables. Overall, I consider it a good PSU, although I would not recommend it for a LAN party PC due to weak spots in vibration damping. As of October 2018, PCPartPicker lists the EVGA Supernova 650 G3 at just under $60, the cheapest name brand 650W PSU with at least an 80 Plus Gold rating. Zero problems with installation. No problems at 2 weeks from installation. Now comes the exciting part of opening it up and trying to understand how it works. EVGA probably isn’t the first name you think of regarding high-quality PSUs, but they’re certainly no newbies considering they made what is basically the Tesla Roadster of PSUs – top-flight specs that almost everyone wants, but also massive overkill and beyond budget for most PC builders. It's quiet, efficient, reasonably priced, comes with a solid warranty and has strong reputation in the building community.
