About this deal

FSP kept the bundle fairly basic, with just a regular AC power cable, typical mounting screws, and a small manual to be found inside the box. The noteworthy addition to the bundle is the SFX to ATX adapter that allows the Dagger to be installed in ATX-compliant cases, allowing users the flexibility to switch between ATX and SFX cases at will. This isn't really a massive concern, and only really applies to high end GPUs (as they are very large and have huge power budgets), but it can cause system crashes/shutdowns if the PSU isn't able to handle the spikes, either through OCP/OPP triggering or through voltage dropping too low for the system to stay on. And it varies a lot between PSUs - I've seen 850W units shut down when powering a 3080, but I've also seen 600W units powering 3090s with no issues. Hence why the ATX 3.0 spec is trying to standardize this somewhat.How has this not caused a giant controversy? I mean, it sounds to me like it's something which can happen more often than you'd expect and could cause many problems, how has this become acceptable at this point in time? Since the new era GPUs require more power— especially the RTX 4000 series, an ATX 3.0 PSU ensures your build is future-proofed for power-hungry GPUs. Color ATX 3.0 PSUs are specifically designed to handle GPU power spikes effectively. With the NVIDIA RTX 40 Series GPUs consuming nearly double the power, these PSUs can manage power spikes of up to 2600W, ensuring system stability during intense gaming sessions. What's the role of Alternative Low Power Mode (ALPM) settings? For those ATX3.0-compatible PSUs without a native 12VHPWR cable but with a connector, the excursion request is formly 150% or 200%?

Semi-modular PSUs have only the most important cables attached, with room to add extra cables as needed. NanochipSo given that this power supply doesn't have a physical ATX12HPWR slot (and seems to be using converter cables), I have two questions. Once you have decided on the form factor and modular design, the next thing you need to consider is the efficiency rating you can afford. The 80 Plus Gold efficiency rating is usually the sweet spot for most gaming PC builds. Anything above this is overkill and quite expensive! ATX 3.0 Compatible The front side of the Dagger Pro is home to the connectors for the modular cables. A subtle legend is printed on the chassis itself, in the same gold color as the rest of the artwork. The connectors are keyed, so it is not possible to insert any cable into the wrong connector.Does this PSU comply with the same power excursion requirements of ATX3.0 PSUs that come with the ATX12HPWR port? If not, then how does this PSU's power excursion capability compare to the more stringent requirements of ATX3.0 PSUs that come with the ATX12HPWR port? The 92 mm low profile fan responsible for the cooling of the Dagger Pro 850W is supplied by Power Logic, a relatively well-known fan manufacturer whose products are frequently found on GPU coolers. It features a simple but very reliable double-ball bearing engine and has a maximum rotational speed of 2500 RPM. The Phanteks Revolt PSU has been designed to offer outstanding performance and efficiency. Thanks to this, these PSUs can produce exceptional power output with minimal cooling. In fact, the cooling fan won’t even activate until the PSU reaches 30% load for zero noise. Once this load is reached, optimum temperatures can be maintained, thanks to the Revolt’s intelligent temperature control, which carefully balances cooling performance and noise levels. In addition to being whisper quiet, the 92mm fan’s fluid dynamic bearings also reduce vibrations which is ideal for minimising wear and tear. In fact, Phanteks is confident in every component within the Revolt SFX, that they offer an amazing 10-year warranty. Phanteks Revolt 850W SFX PSU Specifications: ATX 3.0 Compliant We won't know until it's tested, but I have my doubts. ATX 3.0 currently "asks" for a PSU to do 2x it's rated capability in a power excursion event; which is very unrealistic. Especially when you get into higher wattage and/or smaller footprint PSUs. This isn't really a massive concern, and only really applies to high end GPUs (as they are very large and have huge power budgets), but it can cause system crashes/shutdowns if the PSU isn't able to handle the spikes, either through OCP/OPP triggering or through voltage dropping too low for the system to stay on. And it varies a lot between PSUs - I've seen 850W units shut down when powering a 3080, but I've also seen 600W units powering 3090s with no issues. Hence why the ATX 3.0 spec is trying to standardize this somewhat.

ATX 3.0 is the new specification standard for PSUs. This new design adds a new PCIe 5.0 connector with 12 + 4 pins alongside the usual 6 or 8-pin connection.To be 80 Plus certified means that the PSU has at least 80% efficiency at three load levels of 20, 50, and 100 percent loading. I recommend getting a fully modular PSU since it offers total control of your build’s cable management. Efficiency Rating But some manufacturers also design them in white colors to cater to builders looking to build sleek, all-white gaming PCs. No. The wccftech piece was complete crap. PCI-SIG never said not to use adapters. Read the actual letter in the article. wccftech extrapolated from the letter that they shouldn't be used, but whoever leaked the letter to them did not leak the attachment that explained the "situation" further. Tt uses this in their PR for GF3: www.thermaltake.com/toughpower-gf3-1650w-gold-tt-premium-edition.html

DC-DC Converters: 6x IPS FTD05N03NA (30V, 75A @ 100°C, Rds(on): 6mOhm) PWM Controllers: ANPEC APW7159C Due to size restrictions, the designers were forced to use three APFC capacitors, the combined total capacitance of which is 420 uF. All three capacitors are supplied by Nippon Chemi-Con. There are two primary side inversion MOSFETs that form the heart of a half-bridge design, feeding a rather small unique transformer.

The FSP Dagger Pro 850W SFX PSU

Simply put, an 850W 80 Plus PSU will draw a maximum of 1,062.5W at 100% load, which means less wattage is wasted as heat in the conversion process, saving your energy bill. But SFX PSUs come in smaller designs to fit in small form factor (SFF) cases because they don’t have the space needed to fit a full-size ATX PSU. ATX power supply units are usually the industry standard for most builds. They are designed to fit the regular ATX, large EATX, and most mATX PC cases.

Jul 16th 2020 The Curious Case of the 12-pin Power Connector: It's Real and Coming with NVIDIA Ampere GPUs (178) A fully modular power supply unit lets you use only the cable you need for simple and clean cable management. I presume you already have the estimated total wattage that your PC will draw, and an 850W PSU is the ideal power supply unit to complete the build. You’re more likely going to need an ATX power supply. That’s unless the case manufacturer specifically states you use an SFX one. Modular Design wolfIf I'm interpreting this correctly, that's mitigation for transient power spikes? and again if I'm interpreting correctly, that means ~1700w spikes for at least 100 µs are accounted for?

Are there any potential overcurrent issues with using the adapter cable (I read yesterday that the PCIe-SIG is warning of potential for issues with some PSUs/cables that convert 8-pin PCIe power cables to a ATX12HPWR cable)? A Phanteks Revolt power supply can match the needs of modern components. With many high-performance CPUs requiring over 200W and GPUs reaching 450W+, an 850W supply is highly recommended. With its modular design, the Revolt PSU can support a wide variety of devices including NVIDIA RTX 40 Series GPUs, thanks to its dedicated 12VHPWR output. This new connection can deliver an astounding 600W along a single cable. All power is supplied safely thanks to the many forms of output protection Phanteks has built into the design, including Overpower, Over Voltage, Short Circuit, and Over Temperature protection.
