Reliable Power Supply That’s Never Let Me Down
The EVGA 700 BR 80+ Bronze 700W has been powering my editing system for years without a single problem. It’s been rock solid and consistent, even when running multiple drives, RAM, and 4K editing sessions. The power delivery is clean and stable, and it stays quiet under load. I really appreciate the peace of mind knowing my components are well-protected — no random shutdowns, no overheating, no buzzing. It’s also nice that it comes with an 80+ Bronze rating and a 3-year warranty, but honestly, I’ve never needed it. This PSU has just worked flawlessly since day one. If you’re building or upgrading a system and want something dependable and affordable, the EVGA 700 BR is an excellent choice.

Been using for 2 years with no issues.
Good quality, quiet, doesn’t put off too much heat, installing is as easy as any other power supply, fits in a tight budget, been through many power outages with no shorts or issues at all.

Looks good and installs smoothly, cable clip quality and HEFT of main unit give nice feel.
People might wonder what's the difference between a "high end" PSU (power supply) like an EVGA unit vs a cheaper one like, say, a RaidMax Bronze 635 watt, which is what I got this EVGA B5 550 watt to replace. And let me tell you, you can literally FEEL the difference. The materials of higher quality capacitors are much DENSER and therefore HEAVIER than the same sized and rated capacitors of a lower quality power supply, or even a higher rated one, so many higher quality PSUs will be heavier than cheaper, lower quality ones. While weight isn't always an indicator, the simple fact is that the denser coils and capacitor materials used to make better power supplies simply end up weighing more. This also gives the unit quite a bit of HEFT that makes it feel good in the hands. The clips on both ends of the modular cables were also very good quality, clipping in easily once I was able to get a light on to see them clearly within the poor visibility of my case. Which IS NOT the fault of the PSU. I ended up using all but one of the cables, the included molex connection one. The cables also connected to my ColorfulMod brand extensions PERFECTLY and with a satisfying click, unlike those on the cheap and low quality RaidMax, where even after forcing the connections together, the cords still didn't connect fully. The black sleeving and black rubber insulation of the cables means you don't need to purchase extensions to make your build look good, however. Only complaint is about the length of the sata power cable connections, but they are the standard length for an atx PSU so my issues is with the standard connection length, and for the low cost of a quality unit, I don't expect them to include sata power extensions, and not sure EVGA even makes their own in-house Sata power extensions, though I haven't checked. If they do and you have case accessories or drives that need sata power spread across your case, buy them, if they don't make in-house extensions, make sure to get good quality ones to match the excellent quality of their cables. The VGA cable DOES have a built in split for hooking up a 16-pin, 12-pin, or 14 pin Graphics card as well as 8 or 6 pin, or for plugging in extensions to do so, which is a great feature, I was worried I was limited in choice of graphics cards and might have to return the unit and get a higher rated on with another VGA cable connector, but glad I see I don't have to. This is a VERY good 550 watt power supply, and if using a 65w CPU (like many AMD Ryzen 5 chips), can probably easily provide enough power for a 3070 and the rest of your computer. The 600/650 recommendation is mostly for CPU overclocking..or Intel, or 120w base power using CPUs, so this is worth looking at if you are building a new pc, upgrading an older pc with a very old PSU and want to go modular, and ESPECIALLY if you want to put a power supply in a prebuilt gaming pc you purchased that has a unit in it that has a possibly non-rated or supposedly rated psu from a company you can't find any information on.

700w, Non-Modular, 80+Bronze, 3-Year Warrenty
The PSU on my 8 year old (but still worthy) Dell 8910SE bit the dust and I needed a replacement - this for the bill albeit overkill on the wattage for the 8600/RX480 combo the PC is equipped with. It's a fairly decent build quality for such a cheap power supply. Cables and connections all feel higher quality than whatever OEM Dell PSU lived in my PC before. Installed perfect, booted perfect. The 3-year warrenty says a lot about the components you can't see though lol so don't expect long lifespan or stellar performance if your PC is full of more modern components pushing more wattage. Is this a useful power supply for some folks in some situations? Yes. Is it low teir? Also yes. But hey, if your expectations are in line with the reality of it's flaws, it does the job just fine.

Great PSU.
I've had a number of EVGA PSU's over the years, and while I do prefer Seasonic, EVGA is my budget go-to, granted I consider "budget" here to be more expensive in relation to other components. It has a bit of heft (indicator of good electrical components), is compact in size, has a quiet fan, and has solid cables. It also has the typical main on/off switch; and an eco-mode on/off switch, which I admittedly never use. This unit comes with a 24-pin motherboard cable, a single unbridged 4+4 pin CPU cable, a single bridged dual 6+2-pin PCIe cable, two 3-device SATA cables, a single 3-device 4-pin Molex cable, and a 4-pin Molex to floppy adapter (the only cable which is flat). The cables in this one aren't flat, which I actually appreciate because it makes them easier to shorten. Which brings me to my only gripe: they're so darn long. Seriously, it's almost as if the length of them is meant to compensate for the space that would otherwise be freed up by leaving a few off. To my knowledge so far, nobody makes affordable short cable kits premade for this make/model, either, and if you're buying a Bronze-rated supply, chances are it's going into a micro-ATX form factor due to price points on components. My gripe about the cables' length aside, it's a great unit. If you're using a cheapo psu, you'll instantly notice a difference in your system's performance by replacing it with a quality one. Don't cheap out on this component in your rig, even if you can't get a Gold-rated or better one.

Vengo de aprender a la de malas por que vale la pena invertir en una fuente de poder, anteriormente compre una PC prearmada en Amazon y yo que no sabia o era muy nuevo en el mundo del pc gaming no tome en cuenta que venia con fuente generia, y a la primera variacion de volatje de llevo mi tarjeta grafica por lo cual tuve que gastar en una nueva tarjeta grafica y esta fuente de poder que al momento de escribir esta reseña no he tenido temas con variaciones de voltaje ni cuando se ha llegado a ir la luz eso si, tambien compre un no break para minimizar los daños y añadir seguridad extra

Excellent. It powers my whole system. Before this I was using a thermal take power supply. Within 3-4 months the thermatake psu decides to give out on me, and I contacted thermaltake support and they refused me a refund/ new power supply. I do not recommend thermaltake for power supplies. After doing some research into a more reliable brand, I came across evga. And ordered this bad boy. I’m very content with my purchase. And straight off the bat as a comparison. I weighed the power supply. comparing it to my old thermaltake one, out of curiosity. Evga’s power supply was 4 times heavier than thermaltake. Now i’m not a PC professional by any means, but this just tells me Thermaltake uses cheap chinese parts and don’t really care about quality. Evga is the opposite, and it shows. Evga cares about the quality of their products and they continue to make high quality power supplies. Don’t make the same mistake I did though. Don’t buy thermaltake power supplies. Buy from reliable brands. Evga is a reliable brand.

I’ve had the power supply for like 3 years or so and I’ve never had a single problem with it and I use my computer almost everyday for hours and hours
