? ASUS ROG Strix GeForce RTX 3070 : 2x PCIE 6+2 Pin ? Gigabyte RTX 3070 Gaming OC 8G : 1x PCIe 6+2 Pin, 1x PCIe 6 Pin ? MSI RTX 3070 Gaming Trio X : 2x PCIE 6+2 Pin ? Smaller Dimensions: Gigabyte RTX 3070 Gaming OC 8G (300 mm), MSI, Asus ? Heavier: Asus (1.8kg), MSI (1.5 Kg), Gigabyte (lower than 1 Kg) ? Best cooling system: Asus with MSI following closely, Gigabyte's card comes last ? More Connectors: Asus Rog Strix (3x DP 1.4a, 2x HDMI 2.1) ? Highest GPU Core Boost Clock out of the box: MSI (1830), Gigabyte (1815), Asus (1725) ? Lowest Board Power Limit Default: Asus (220W), MSI (240W), GB (270W) ? Highest Board Power Limit Max: Asus (350W), GB (270W), MSI (250W) ? Best Performance out of the box: Gigabyte RTX 3070 Gaming OC 8G (because of the highest default board power limit at 270W), Asus, MSI ? Best Rendering Performance: MSI, Gigabyte, Asus ? Lowest Max Gaming Operating Temperature: Asus (58.1C), MSI (61C), Gigabyte (66.2C) ? Operating Noise at Gaming: Asus (20.9 dBA), MSI (21.4 dBA), Gigabyte (32.8 dBA) ? Lowest Power Consumption at Gaming: Asus (216W), MSI (227W), Gigabyte (256W) ? Higher Performance per Watt Ratio: Asus, MSI, Gigabyte ? Best Performance with Overclocking: MSI, Asus, Gigabyte I would buy the Asus, and if I couldn't find it, then the MSI, and for last, I would leave the Gigabyte. If I didn't care about noise output and wanted the best performance out of the box and compact dimensions, I would go with the Gigabyte. The MSI is quite good, being in the middle offering good performance, low noise output, and high Performance per Watt ratio. In general, get an Nvidia RTX 3070 if you can find one at a reasonable price if you are after good performance. It will allow you to play games at the greatest detail and high resolutions. In some games, even 4K resolutions with high details won’t be a problem. Raytracing is a cool feature as well if the game supports it properly. Finally, an RTX 3070 is on par with an RTX 2080 Ti in overall performance, and it is a bit behind the RX 6800 (without DXR). Compared to an RTX 3080, the 3070 loses from 14% at HD, 19% at QHD, and 24% at 4K. #HWbusters #Nvidia #RTX3070 ?

? Model number: Gigabyte P450B ? OEM: MEIC ? Efficiency: ETA-S (83 %), 80 PLUS BRONZE ? Noise: LAMBDA-S (42 dBA) ? Modular: No ? Dimensions: Compact ? Price: $50 ? Warranty: 3-years ? Power Specifications: Single +12V rail ? Power Distribution: 103W on the minor rails, 432W at 12V ? Cables: 1x EPS, 2x PCIe, 6x SATA, 3x 4-pin Molex, 1x FDD adapter ? Cable Length and distance between them: Long enough cables with 120mm between all peripheral connectors ? In Cable caps: No ? Internal Design: Single-sided PCB, medium-sized heatsinks, and a bridge rectifier that isn’t bolted on a heatsink. ? Transient Filter: It is complete. It even has an MOV. ? Inrush current protection: 1.5 Ohm NTC thermistor. ? Primary Side: APFC and double forward topology ? Secondary Side: Passive Rectification & Group Regulation ? Soldering quality: Good enough. ? Build quality: Low-cost FETs are used on the primary side, and the same goes for the SBR (Schottky Barrier Diodes) on the secondary side. The +12V rail uses some SBRs that I have never encountered before. ? Caps: 85C Teapo LH bulk cap and unknown 105C caps on the secondary side. ? Rifle bearing fan by Bok ? Tolerance to high temperatures: It delivered 110% of its max-rated-capacity at 41C for a short period, without breaking. This doesn’t mean that the PSU will survive for long under harsh operating conditions. ? Thermals: With 230V input and mid load, but without active cooling, the bridge rectifier goes up to 74C. With lower than 115V input and full load, with the fan at full speed, I expect high temperatures on the bridge rectifier/ ? Load Regulation: Decent at 12V and within 3% on the other two major rails. ? Ripple Suppression: Ok on all rails with 12V staying below 50mV at full load with 115V input at 40C. ? Transient Response: Good at 5VSB, mediocre at 12V, bad at 5V, and terrible at 3.3V ? Protection Features: OCP is correctly set at 12V, while it should be lower at 5V where the rail is close to the lower allowed limit. OCP at 3.3V and 5VSB is set high. OPP is correctly set, and the bad news starts with OTP, which doesn’t seem to be present. ? Hold-up Time: above 17 ms ? Inrush Current: Low inrush currents. ? Leakage Current: Very low readings here, which is a good thing, of course. ? Overall Efficiency: Very Low. ? Overall PF: Avg with 115V and bottom low with 230V. ? Overall Noise Output: High ? Overall Performance: Low Bottom Line: An affordable PSU with higher performance than the P550B, since the lower capacity helps it achieve better ripple suppression, especially at 12V, and tighter load regulation. The platform is outdated and uses low-quality parts. It has a rifle bearing fan, though, ... https://www.youtube.com/watch?v=SJ4FPAklwWY
