[SOLVED] Be quiet Power Supply?

[jennytrem]

Hello guys, I'm back for another question for my first build.

I have literally no clue which power supply I should buy. I won't buy something too pricey but I won't cut my budget for this part.

I'm kinda aiming for a be quiet but I rly don't know how to calculate my wattage as I can't rely on most estimated numbers. Can you please help me?

This is my build so far:
AMD Ryzen 5 3600
Cooler Master Hyper 212 Black Edition
MSI B450 Tomahawk Max ATX
Corsair Vengeance RGB Pro 16GB
Kingston A400 240GB
Crucial P1 1TB
MSI GeForce RTX 2070 Super Gaming X Trio

This is the least expensive quality unit that I see available in or near your region that you'd want to even bother looking at.

This would be a moderately better choice.

If you go to beQuiet web, first page will show you "PSU calculator" button:

My experience with beQuiet products is very good so far -I use beQuiet Straight Power 11 550W PSU right now. Yes, they can be pricey (depends where you buy), but so are other better quality PSU's. If not beQuiet, then I would choose Corsair TX-M that Darkbreeze suggested. CX-M is considered as "basic" PSU and I think your current setup deserves better than that.

BTW - MSI recommends 650W psu for MSI GeForce RTX 2070 Super Gaming X Trio.

-is true. Manufacturers do that to ensure product will work under all circumstances (i.e. power hungry Intel 10900K CPU is used). In OP's case however, 550W is enough even if he decides for AMD 3900X later.

That graphics card has two 8 pins plus slot power. It can't pull any more power than any other dual 8 pin card. The absolute most that card could pull, theoretically, not counting any momentary spikes that might occur, would be 375w. That's the same for any card with two 8 pin auxiliary connectors, which are 150w each maximum by specification that MUST be adhered to in order to allow the card to conform to the PCIe spec, plus 75w for the PCIe slot, which also must be adhered to. For PCIe 3.0 graphics cards and cables, those are the limits.

Newer PCIe 4.0 compliant cards and power supply cables might see a change due to the demands of the new Nvidia cards but I haven't seen anything concrete saying that those numbers have changed, yet, aside from the 12 pin connector.

A 550w unit, if it is a very good one, is plenty for the OP's configuration, but I would certainly not be against going with a 650w unit simply to add a little additional headroom and provide some freedom for future upgrades or overclocking.
