[SOLVED] 1st PC Build - Is 550w Enough?

[Moneytrain81]

I'm in the process of getting all my parts together to build my 1st ever PC. I bought a Corsair CV550 psu as that seemed a good balance of probably enough power and not overspending.

However I'm starting to think 600+ might be a safer bet.

The build is -

Ryzen 5 3600
ASRock Steel Legend B450M (returning the MSI B450M-A Pro Max I bought originally)
Patriot Viper 4 Blackout 2x8gb
Corsair MP510 480gb M.2 ssd
5 x EzDIY Fab rgb fans

I'll be adding ann internal wifi adapter too.

I don't have my mind set on the GPU though yet. I don't have 30series or 6000 money, unless they announce some bargain £300 cards this year. So I've been looking at 2060 & 5600XT as I want 1440p but only need a constant 60fps as my tv doesn't go higher.

Is my current PSU choice going to be OK, or do I go 600+?

550W is perfectly fine.

I wouldn't recommend the VS series, since that's their "bargain basement" line.

CV? Is that a new line? I thought it went from VS to CX. Their TX series are good price/ quality. Obviously RM is better, so on and so on.

The CV in between, but closer to the VS series, think VS with minor upgrades. Still nothing for a gaming system. Only the CV 650watt (if nothing else decent available) would maybe be a acceptable choice since having LLC and DC to DC.

Are you saying it isn't enough?

go on pcpartpicker.com add all parts and see i right corner voltage multiply that number with 1.6 and u will get optimum PSU

Came out as 374 watts, which then works out to 598.4 needed. But that was me being cautious and trying a 2070.

With a 5600XT it all totals out to 495w.
With a 2060 it totals to 510w.

So as long as my gpu budget stays low I'm all good? If my gpu budget suddenly increases somehow, then I'll have to upgrade to 650 to be safe.

I wouldn't abuse your expensive hardware with a cheap PSU. Grab something mid tier like a SeaSonic or EVGA G4 650w. Plus you will have plenty of juice left and be future proof possibly with a system that can take up 600w when gaming in the future and what have you.

The CV is essentially a Bronze rated VS, so technically superior to a VS, but only in one specific area. Everything else is the same design. The CX-M is barely a step up from that, it's not until you get to the CX that you'll see a change in architecture and platform.

So the CV is decent, just really not designed for the stresses inherent from a gaming gpu. RM/TX-M would be a better choice, a step up from the CX.

@Moneytrain81, I'm pushing a 2070Super, Ryzen 3700x with OC, full custom loop and 4 case fans from a 600w SFX psu that's the size of 3x packs of cigarettes stacked together.

You don't need anything higher than 550w for your budget build, your components won't demand what you think they will. And that includes pcpartpicker.com. You'll be looking at 100w or less for cpu, about 100w for the motherboard and peripherals/storage, and a maximim of 225w for a 2060. (2x 6pin +75w pcie). Grand total somewhere around 425w if you maxed all components, complete 100% psu load. Which is physically impossible. You'll never completely max out everything simultaneously. At best, you'll pull approximately a 70% load under very heavy gaming conditions. (load, not usage). So you'd be looking at heavy gaming conditions pulling somewhere around 300w.

Good to know, thank you.

The gaming aspect would mostly just be Warzone/COD, maybe Forza Horizon 4 on game pass, for up to 4 hours at a time. I don't need ultra settings etc, just a solid 60fps ideally at 1440p. Other than gaming it will be used for light Illustrator work sometimes. Not really looking to OC anything yet too.

The CV650 has DC-DC only for the minor rails (+5V and +3.3V), while on the primary side has a double forward topology... not LLC resonant as far as I know.

EVGA G4 650w

That PSU doesn't exist my friend... I wouldn't recommend the G5(if that's what you're referring to). They changed the OEM to FSP and it's worse compared to the G2/G3 with the Superflower Leadex II platform.

Yeah you are right, am not as sharp lately. It is still better than the lower wattage versions.

Yeah... clearly better than the group regulated ones.

Sorry I meant G5 or B5 its pretty new just came out.

For a 1st build like this i think you picked a good combination (unlike me built a basic lga 775 system for 100$+) the psu should be fine but upgrading it is reccomended for future proofing and lowering the chances of gpu power spike turning off your system due to psu not being able to handle it, for overclocking related things, no dont overclock ryzen since they dont have the best overclocking potential, instead undervolt and maybe slightly underclock it, the voltage should problably be 1v -1.05v for undervolting and if you want to lower it further then underclock the ryzen and lower voltages further, for gpu i would reccomend 6700xt since it delivers 3070 level performance with alot of vram so you can use ultra settings if you want, i reccomend you to undervolt and maybe undeclock it as well since you are targeting a steady 60fps right? And i would reccomend installing msi afterburner to undervolt and underclock the gpu and riva tuner statistics server to view your fps, i would reccomend tuning (undervolting and underclocking) your parts until your heaviest game reaches 75fps average so you get high efficiency and lower power bills, sorry for the wall of text xD hope this helps!
