Recommend wattage

[TBsparkez07]

I have a i5 9400f (65w)

 

msi mpg z390 gaming plus

 

coarsair vengeance lpx 3200mghz

 

samsung 970 evo 500gb (m.2 nvme)

 

2 Tb external hard drive

Thermaltake Smart 500w 80+
 

will I be able to run a rtx 3070 without a grad in my psu ? Thanks for your help

No. Look into getting something at or above 650W from Tier B or higher on this list:

 

[GhostRoadieBL]

so you have around ~100w of CPU (with the turbo) + ~40w for the motherboard + ~15w of ram/HDD/SSD + 350w+ graphics card = 515ish+ watts / 0.80 for 80% efficient psu is 640watts at maxed load on everything. I'd look at a 650w or 700w psu to give you some extra power space for fans and accessories. No PC runs 100% all the time on every component so it will probably run on 500w but that's very dangerous for heating up the psu components and not compensating for efficiency.

this is not how eff works

assume 500w is needed first, easy numbers,

a 500w 80+ psu will draw 600w from the wall and covert to 500w for pc without issue,

your electricty bill is 600w   , psu, pc will fine

3070 is just 220w, so 500w shall be fine

[GhostRoadieBL]

I probably used the wrong term, it's a safety factor for component efficiency within the PSU, you can have it 80%, 50% whatever you feel comfortable with stressing the components. The 500w psu will draw as much power as necessary to output but the degradation of the components will be faster at 100% rated output load vs 80% rated output

[AdvilLobotomite]

I would upgrade your PSU.

that depends on how they are measuring TGP, noone has a hands on review yet so it could be 220w at 100% stock clock settings and not boosting or a third party card with an overclock, intel pulls this stuff all the time with underrating their CPU wattage to make it sound more efficient than it really is.

lets look at zotac 3070 twin edge, only 6+8 pin meaning max 300w

we're arguing over 100w on a PSU which will cost between $10 and 20 more. 

 

personally I would never put a 500watt psu in a system running even 400w of power under load. I only really see 4 categories of PSU 100-300w for microsystems, 450-600w for midrange lower end/mid graphics, 600-850w for high end, and 1000w+ for people who already know they need it.

Nvidia recommends a 650W PSU for the 3070 but that is configured with a 10900K, which TDP is 125W (and draws 200W https://www.tomshardware.com/reviews/intel-core-i9-10900k-cpu-review/2). You'll be fine with 500W maybe 550W I think but that PSU is not great.

a 450w psu can run 9900k + 2080ti full load

tomshardware has the 9900k at max load 249.7watts, 2080ti at max 278.6watts with peaks in the 360watt range. 

 

just because it "can" doesn't mean it should, my house not being on fire is worth more than a few extra dollars to put less load on my psu.

My system pulls over 660W+ max load.... And 550W+ gaming...

Brian said not to take it seriously and people should be using a 650W to 750W PSU...

No, you need to get a better quality PSU than that and 650W.

 

The PSU you have is a total piece of garage and has no business being in a PC.

From Toms Hardware..... You have to actually read the article....

During those tests, we recorded up to 332W of power consumption when paired with either the Corsair H115i 280mm AIO watercooler or a Noctua NH-D15S air cooler. Yes, that's with the processor configured at stock settings.

This is not a great PSU. Get something B teir in the tier list.

I recommend the Bequite Pure Power 11 or 7
