Before i begin i want to say no i have not reviewed this unit nor is this a review and all credit goes to Techpowerup as i got the info from them
Alright i thought the EVGA thread cleared it up as to why you should not buy an NEX650G/750G, but a lot did not seemed to get the word or understood why so i am going to make a whole thread as to why not
First off lest start with OEM and the platform used its FSP and its based on a group regulated Aurum, the word group regulated should already tell you whats wrong with it
And before anyone misunderstand no the SuperNova G2/P2 and all the other SuperNova models have NOTHING in common with the NEX650G/NEX750G those are based on other platforms not FSP Aurum based units, so this thread is ONLY about the NEX650G/NEX750G
Quoted from Techpowerup´s review of the NEX750G
EVGA trusted FSP with their smaller SuperNova units, and they, to be more specific, utilized their Aurum platform. Definitely not the platform we would use for a PSU that belongs to a high-end series and one that has to compete with pretty advanced opponents
The main problem here is not crappy capacitors or super crappy build quality its as said before its group regulated
What that mean you might ask?
It means that all the rails are treated as one big group and not regulated independent
The result of that is some truly crappy voltage regulation in fact some of the WORST i have ever seen
Note that all ripple and voltage results are from the unit(s) at full load
This alone here should be the reason why you should not buy it but it gets worse then that
When you are thinking of a group regulated you are thinking well that would make it pretty cheap right? the Rosewill Capstone is in the same price range and sometimes cheaper and is an overall better unit
Again for anyone that are going to misunderstand no the NEX models are not going to blow up nor are they super crappy like some of the stuff from HEC, the word here is very mediocre nothing more
All info and pictures came from techpowerup and the testing has been done by them so all credit goes to them not me.

Its their own fault for selling a unit like that at such a high price
You know if they took 50$ off the price it would not be so bad its still not very good but at least its not a ripoff
And no the EVGA SuperNova G2 models are nothing like the NEX models they are fact the total reverse damm good models for a great price
Its only the NEX models you should avoid

To be fair the NEX models where the first PSU´s EVGA sold
And there is a story behind why they went with FSP and not Seasonic as they planed
Anyway for a first try it could have gone a lot worse then it did but it could have been alot better
Reason for this thread is i still see the NEX models gets recommended and i got tired of saying the same things over and over

Looks like the Corsair CX has competition
. I hope people realize that units built like this are meant for casual FB, YT, or E-Mail rigs. They are not meant to be used by enthusiasts or gamers. Thanks for the heads-up shilka.
I’m almost tempted to start collecting information you put out like this and group it up for you.

* Waits for EVGA Jacob to scold you.
EVGA Supernova G is worse than Corsair CS because they have the same exact name as the higher end G2 units except for one number , unless the retailer does their due diligence to write NEX.
I’m surprised it has a 10 year warranty tbh
Amazon pricing history:

Well it does not change facts just because EVGA Jacob and others dont like them
Something thats seems to be a huge problem with the Corsair fanboys as they scream bloody murderer over the facts in the CX and RM threads

Support seems to be flimsy though as well, so unless that’s changed in the last few months I wouldn’t consider purchasing to begin with.
That is in regards to Corsair. Not EVGA

They should EOL the NEX650G/NEX750G now that they have the G2 models which are everything the NEX models are not
I do think EVGA learned a lot from the NEX models and i also belive they took some feedback
As said for a first try it could have been alot worse
At the end of the day skip the NEX models and go with the G2 its much better in all areas

I think that is one of the things that has surprised me about eVGA, when they try making a product for a part of the industry they have not previously covered, they do quite a decent job, even when compared to the companies who are more experienced in those fields. Just look at the hadron, it’s their first ever case, and it’s pretty well designed.

As i said there is actually a story as to why the NEX650/NEX750 was ordered from FSP and not Seasonic as was the plan
I dont know if this story is true or not as i have no way to confirm if it is or not

shilka, it’s not like the Supernova G2 or P2 were spotless either.
The only reason why they don’t catch as much flak is because 1000W PSUs are not high market share.
What lets EVGA get away with it is they were honest enough to admit the problem and RMA everyone’s G2/P2 that had the issues.
EOL-ing Supernova NEX would be a good idea, but they need to move all the units off once Supernova G2 has sufficient production volume.
I don’t understand the need for so many prefixes and suffixes however.
It ought to be
SuperNOVA Classified instead of SuperNOVA NEX1500 Classified , this was a terrible naming situation as it doesn’t tell the Gold efficiency
SuperNOVA P2
SuperNOVA G2
SuperNOVA G — instead of SuperNOVA NEX_____G
SuperNOVA B — instead of Supernova NEX_____B
the NEX designation is meaningless

FSP can make good units so saying that is not fair and its wrong as well
The NZXT HALE 90 V2 was made by FSP yes NZXT did take part in designing it so maybe thats why it turned out so well?
Anyway the FSP Aurum Pro can take on and even beat the old Corsair AX850 in some areas so bashing FSP is not fair

EVGA has discovered that a small batch of our 1300W & 1000W Power Supplies (P/N: 120-G2-1300-XR, 220-P2-1000-XR, 120-G2-1000-XR) did not meet the quality levels that EVGA stands behind. There is insufficient insulation on the thermal pad by a heatsink which may cause the Power Supply to shut down or be unable to power on. If you have one of these part numbers, please fill in your serial number below on this page to see if your power supply is affected. NOTE: This symptom should not occur on ANY Power Supply that was purchased on October 1st, 2013 or later.

Corsair CX750M 750W Power Supply Review
Not all users are convinced that Corsair makes good power supplies. Mostly budget modifications with a power of 500-650 watts are criticized. Someone is not satisfied with the noise from the fan, someone is concerned about wobbly voltage. PSU Corsair CX750M is an updated variation of the model familiar to many (the former was decorated in green tones).
The letter «M» in the name tells about the modular type of wire connection. The classic line of CX blocks does not offer this option.
The Corsair CX750M is a decent entry-level 750W PSU.
The Corsair CX750M is an entry-level device, although it has been awarded the 80 Plus Bronze certification (many solutions can’t even boast that stability and efficiency guarantor).
The quality of the block itself, connecting connectors and wires (they are made in the form of loops) is somewhat different from what we saw, say, in the Corsair RM750 or Corsair RM1000i (in the direction of cheapness). In addition, the number of these cables is relatively modest for a 750W PSU.
| Corsair CX750M | |
|---|---|
| Power | 750 W |
| 80 Plus Certified | Bronze |
| ATX12V version | 2.4 |
| Fan | 140 mm |
| MTBF | 100000 hours |
| EPS12V connector | 1 |
| PCIe connectors | 4 |
| SATA connectors | 8 |
| Dimensions | 150x86x140 mm |
| Weight | 1. 85 kg |
It is important to note that the manufacturer honestly claims that this is an affordable solution designed for basic systems. Although the cost of the Corsair CX750M suggests otherwise.
Test stand:
Processor — Intel Core i5-6600K
Motherboard — ASUS Sabertooth Z170 S
RAM — PNY Anarchy 8GB DDR4 Blue
Graphics — Sapphire NITRO Radeon R9 380X 4G D5
Storage — Seagate NAS HDD 8TB
Performance and test results air, it’s hard to say for sure, however, Sapphire says it needs to use at least a 500W PSU for the test card (it draws about 225W).
Overclocked to 4500 MHz CPU Core i5-6600K takes at least another 100-120 watts. As a result, the power of the Corsair CX750M for the specified PC, in theory, is enough with a margin.
No critical voltage drop was observed in multimedia tests. There is reason to believe that the possibilities of modifying the Corsair CX750M are enough for more productive accelerators (say, ASUS Strix R9 390 or ASUS STRIX GTX 980 Ti).
The stock fan installed in the Corsair CX750M rotates constantly, but don’t expect noise from it. Exactly like cod, squeak, whistle from the internal elements of the PSU.
Conclusions
Corsair CX750M is a decent entry-level 750W PSU with not the most impressive number of connectors, but 80 Plus Bronze certified and 5 year warranty.
The reviewed product, in our opinion, is too expensive in retail. For example, the Corsair RM750 block is priced at the same money, but this, as you understand, is a much more efficient option.

XPG Core Reactor 750W Gold 9 power supply review0001
In the spotlightGaming gadgets reviews And if it is also modular, almost silent, and even with a high energy efficiency factor, like the XPG Core Reactor 750W Gold, the device is definitely worth a closer look.
Specifications
- Dimensions: 140 x 150 x 86 mm
- Efficiency class: 80 GOLD+
- Form factor: ATX12V version 2.
52 - Security: OCP / OVP / UVP / OPP / SCP / OTP / NLO / SIP
- Input voltage: 100 — 240 V
- Input current: 10 — 5 A
- Frequency: 47 — 63 Hz
- Cooler size: 12 cm (fluid bearing)
- Rotation speed: 2400 rpm
- MTBF: 100 thousand hours at maximum load
Equipment and design
XPG Core Reactor 750W Gold for sale in a large box, decorated in black and red colors of the A-Data XPG brand. The packaging is decorated with colorful, glossy prints and certificates; on the front side, the characteristics are described and the complete set is illustrated in detail.
Behind the hinged lid is a set of XPG branded stickers and a multilingual instruction booklet. The block is stored in thick polyethylene foam frames and packed in a pimply bag. A synthetic bag is attached to the side, in which all the wires and spare parts are folded.
The bag is equipped with a secure textile fastener. Looking at the number and feeling the weight of the cables hidden in it, you understand why modular power supplies are becoming more and more popular from year to year: the case is free from extra wires, and in case of modding, you can always connect additional ones; the system looks neater, the air in the case circulates better, and as a result, cooling improves.
Inside the bag are four small screws for mounting the XPG Core Reactor 750W Gold, a power cable and a huge set of cables in a separate bag:
- 1 x 24 pin — detachable connector for the motherboard;
- 2 x 8 pin — detachable connectors for the processor;
- 6 x 8 pin PCI-E 2.0 — connectors on four cords for a video card;
- 4 x 4 pin — ergonomic connectors for peripherals;
- 12 x 15 pin — Serial ATA connectors on three cords for HDD / SSD.
The main cable bundles (CPU, GPU and motherboard) are braided with a thick nylon cord, which makes them look even more massive, but remains quite flexible, while the remaining (peripheral) wires are flat, which makes it easier to lay them inside the system unit .
The length of the wires is more than enough to easily route them inside the largest cases, except perhaps for instances with a hidden management system.
However, even if there is such a cable, it should reach the required connector.
Power supply metal box painted in semi-gloss black. Its dimensions are 140 by 150 by 86 millimeters. The cooler is hidden behind a decorative protective mesh with a large XPG logo in the hub area. The cable connector and the power button are located to the right of the ventilation grill with large (for my taste) pentagonal holes.
All interfaces are marked with names and structured into groups, there should not be any special problems when switching. On the top panel there is a sticker describing the input current, voltage and frequency. The operating temperature declared by the manufacturer is 50°C.
Features and Impressions
For starters, the XPG Core Reactor 750W Gold is moderately quiet as its high-performance 2400 rpm fan is equipped with a fluid dynamic bearing. Sealed chambers are more expensive, but provide reasonably low noise levels and increased durability, and I was able to verify the first one for myself.
The smart curve of the cooler is designed to keep the blade speed within 650-700 rpm, as long as the load on the power supply does not exceed 50%. You will not hear how it works at all, unless the main components of the system require serious energy costs. Behind my fairly quiet case coolers, the rumble of an XPG Core Reactor 750W Gold fan connected to an Nvidia 2070s and an AMD Ryzen 5 3600 is indistinguishable even while gaming.
Load matching and smoothing of current ripples are monitored by premium 105°C Japanese capacitors — the most important radio elements of the power supply, responsible for voltage quality, durability and reliability of the device, preventing its early failure and possible consequences for other PC components.
In general, in terms of safety, the XPG Core Reactor has everything at the industrial level level: protection against overcurrents, insufficient and excessive voltage, short circuits, overheating and current surges is provided. The manufacturer gives a ten-year warranty on the product, being absolutely confident in its protection mechanisms.
The modular XPG device has two impressive achievements in its portfolio. Under the new Cybenetics LAMBA/ETA (Power Supply Efficiency and Noise Certification) testing system, the device received the Cybenetics Platinum standard with a claimed efficiency of up to 91 %.
The XPG Core Reactor 750W received an 80 PLUS Gold rating with a power factor of 0.9 and a 90% efficiency level at 50% load under the established energy efficiency certification program developed and standardized in 2005 by the US Electric Power Engineering Institute.
As a rule, it is this certificate that the average PC user pays attention to first of all when examining power supplies for compliance with the declared capacities. As you can see, XPG received two certifications at once, and in both cases they achieved very good results.
Conclusion
The XPG Core Reactor 750W Gold is a high quality product suitable for most gaming systems. Its modular advantages are a little overshadowed by thick wires, and the price tag bites a little, but the power supply is not the component to skimp on when building or modifying a gaming PC.
