Do you think i need a new PSU?

all my specs should be in on my profile but if you cant see them for any reason, heres my system.

4770k @ 4.2ghz
GTX 1080ti sc black evga
z87-gd65 msi mobo
H80i corsair cpu cooler
1tb ssd
128gb ssd
2x 2tb HDDs
16gig ram
3 case fans besides the two for the cpu
elite hyperbeast s340 nzxt case

and a corsair TX 750 psu.

so heres the thing, just upgraded the graphics card from a 780 to 1080ti. all seemed well for like 2 weeks. last night i have been seeing dips in frame rate that occur like every 15 seconds.

example: Overwatch i would be at around 200 frames per second, and then dip to like 60 or lower for just one instant and back up again, then repeat.

this didn't happen with the 780 and the dips in frame rate realllllly screw things up. so im just wondering if you guys think a tx 750 psu is enough for this or should i just say screw it and upgrade?

any thoughts? thanks.

The PSU you have listed under your sig is known for having very poor ripple suppression so yes replace it
And you dont need a 750 watt PSU unless you are going to have two video cards, a 550 watt is more then enough for a system with a single vide card in it.

hey thanks for the fast response. while i waited, i went to newegg.coms psu calculator and put in my specs and it recommended anything over 705watts.

no im not going to sli. and do you have any recommendations for PSU? dont know tooooo much about PSUs oddly enough.

Forget about using any of those so called calculators as they are all rubbish and wrong
http://www.overclock.net/t/1598887/why-all-online-psu-calculators-are-wrong-and-is-total-bogus

705 watts ??? even if i took 35% off that ridiculous number it is at least 100 watts over what your system is ever going to draw in the real world
Almost all systems with a single video care will draw less then 300 watts unless you are messing around with BIOS and/or hardware volt mods and/or LN2 cooling

As for which PSU you can pick either the EVGA SuperNova G2/G2L/P2/G3 or the Bitfenix Whisper.

thanks. the g3 pretty much the best ones from evga im guessing? want to get the most efficient/modular one i can get. you say 550 is good. is that without overclocking? i plan to slightly OC the card and keep the CPU at 4.2ghz.

would i have room for peripherals like rgb k70 and usbs charging my phone, Blutooth usb for my wireless headset, etc.

even with overclocking 500W is plenty.
I am running a 4770k@ 4.1GHz, a 970 with custom bios for overclocking, and a full custom loop with all fans and pumps at full tilt and I can't get my computer to pull 500W from the wall even if i tried. even if i did pull exactly 500W from the wall that doesn't mean the computer is using 500W, if the PSU is 80% efficient at that wattage draw then that means the computer is using 400W out of that 500W, if it is 85% efficient at those numbers then it is 425W being used.

Its 550 watt with overclocking not without and as i said you wont even break 350 watts unless you are doing really extreme stuff
More down to earth systems are actually somewhere around 250 watts and maybe 300 watts in some cases

Only downside to the G3 is the very aggressive fan profile the G3 has in hybrid mode
Many G3 owners complain about the fan being too loud at too low loads

The G2 is while older and worse by a tiny amount is much more quiet.

Edit: if money is no problem at all you do have the option to get a Seasonic Prime Gold / Platinum / Titanium
These are some of the best units you can buy but you also have to pay through the nose for them and there is no 550 watt option as the smallest one is 650 watt.

oh nice. what makes the seasonic so much better than evga's PSUs?

and i see the seasonic gold starts at 115 dollars and the titanium at 150 for the 650watts. which is no problem, but just wondering if the 10% efficiency warrants the 35 dollar difference?

Voltage regulation is a little bit better on the Prime then on the G2 and the G3
And ripple suppression is slightly better but Seasonic does it without the capacitors built into the cables like Super Flower does

And its not 10% better efficiency going from a G2 or G3 its 6% at most and no its not worth spending extra to get the Titanium version unless you are one of those that just HAVE to save those $5-10 a year on your power bill.

Edit: EVGA does not actually make any of the PSU´s they sell its all made by a 3rd party OEM in China and almost all brands (Corsair included) with a few exceptions does the same
Seasonic both make and sell their own units and they sell to a 3rd party company like XFX which are all Seasonic units just rebranded

The OEM for the EVGA SuperNova G2 and G3 is called Super Flower and the platform the G2 uses is called the Leadex and the platform the G3 uses is called Leadex II

Awesome! Looks like im gunna go with the seasonic gold version. No reason to waste the money on the titanium from what you said.

Hopefully this fixed the frame dropping issue im having. If not, at least i have a better psu.

Thanks for the help!

It might or might not help your frame drops but a new PSU is going to give you a more stable overclock as your old PSU is rubbish compared to almost anything modern

You should think about getting a better CPU cooler as well
http://www.overclock.net/t/1590547/why-you-should-probably-not-buy-a-clc-cooler

New PSU and new CPU cooler and you will be able to overclock even higher then you can now
Or you can leave you OC as it is and get it more stable and get lower temps.

Lol well it so happens i was in the market for a new cooler. Was gunna get another corsair cooler of the same type. I will read the link. At work atm. Let me know your recommendations

Drop any idea of getting a CLC cooler and either get a good air cooler or a real AIO kit from either EK or Swiftech
Any good air cooler fron Be Quiet / Phanteks / Noctua or Cryorig is going to be a lot better then the mediocre H80i you have now

I did not know about those

Yes just be aware that you need to fill it up with liquid as it evaporates over time
But why are you looking at a 120/140mm rad and not a 240/280mm rad?

Edit: looked at the case you have and what in gods name is that you have?
Never seen a case with no support for a 240/280mm rad in the top and the only place you have room for a 240/280mm is in the front.

yeah, no room for the top. but its ok. i think i might just go for a regular heatsink with fans.

So here's what i found for a heatsink from cryorig: http://www.cryorig.com/r1-ultimate_us.php

The R1 ultimate seems to be their flagship. problem is, i think it only has a 28mm clearance.

idk if its adjustable for the ram i have which is right below:

https://www.gskill.com/en/product/f3-12800cl9d-8gbxl

This ram apparently has a height of 40mm.

any thoughts?

The Noctua NH-D15 has much higher RAM clearance
Or you can buy a single tower air cooler that wont overhang RAM slots.

well i think the universal version would be fine with the ram....buuuuuut, apparently my case only supports 161mm cpu coolers and i think the R1 is actually 168mm. so thats not gunna work.

i think i might have to go with the single tower cooler. gunna look around a bit.

The H7 is a lower tie cooler and is meant to compete with the Cooler Master Hyper 212 Evo
Its not a bad cooler in fact for the price its one of the best coolers for the money

But the Phanteks is a little bit better
Going from a H80i to a H7 is not really an upgrade its more of a sidegrade.
 
#23 ·
well apparently my h80i seems to be idling a lot around the low 40s @ 4.2ghz lately which appears to be pretty high IMO.

The H7 at 4.3ghz on a 4770k idles around 27 degrees with load at 71 from the reviews ive seen. this is using cinebench.

the phantek however, on a 3770k (couldnt find one with 4770k) at 4.4ghz idles around 27 as well but 63 at load. using prime 95 though.

both would be an upgrade since this h80i seems to not being doing much in the first place.

any huge differences between the 4770k/3770k and cinebench/prime 95?
