Hey guys. I am looking in upgrading my current rig which consists of:

Asus Prime Z270-A motherboard

i7 7700k cpu

Corsair H100i 240mm water cooling

16gb ddr4 2133mhz ram

Msi Duke Rtx 2080 ti

256gb SSD

2tb HDD

80 Plus Bronze 750W psu

 

I am looking in replacing my motherboard with a Gigabyte Z390 Aorus Pro. With the new motherboard ill be adding an i7 9700k with new 16gb G-Skill Trident 3000mhz DDR4 ram. I am hoping that it will be an easy swap and I can keep my old hardware but I am not sure if my 750Watt power supply will be sufficient. Will I need to upgrade my PSU as well? Any help would be greatly appreciated!

80 PLUS Bronze is not a brand.  And wattage isn't everything.

 

It would really help if you provided information pertaining to your power supply if you're going to ask people questions about you power supply.

 

If it's an older double forward topology w/o DC to DC for the non-primary rails, you're likely going to have problems with the Z390.  Would also have problems with your 2080 Ti.

 

You're not having problems with the 2080 Ti now?

Almost any build with only one graphics card can be sustained with 750W, and your i7 + 2080ti combo shouldn't be any different.

I second Jonny here, brand name and model would be more telling and if it's an older model, I'd personally recommend getting a newer model with a higher than bronze rating.

Doesnt look like any reviewers touched that with a 10 foot pole. Get a new, reliable unit from a reputable manufacturer

 

Take something from this list between tier S-B

For those who don't want to click on the link:  The PSU is an Ultra HS750.  

 

It's 750W "peak".  Says so right on the box.  It's exactly what I thought.  Double forward, no DC to DC.... and it's OLD.

 

You have money to buy a 2080 Ti and a Z390 board, you should have money to buy a PSU that won't kill it all in the first place.

Ultra's aren't too good of quality, considering you're upgrading to an i7-9700k and a nice mobo, with the 2080ti you already have and whatever else you're putting in it, it sounds like its going to be a pretty decent rig, I'd definitely get a better 80+ gold or better PSU. From a reputable brand.

I have an EVGA 850 GQ 80+ Gold, it's a very decent PSU and I got it on sale for $79.99 at my local Best Buy.

brand and efficiency are very important , for example your build will consume about 480 w at 100% load which it too high but we will take that as an example , youwill be fine using a 80+ gold 500w power suply , but if you couldn't afford 80+ gold , use 80+ bronze but make sure you buy a trusted and well reputed brand and you will be fine ;D

Okay I am going to upgrade to a gold rated psu. But after mentioning that theres a possibility my current psu could damage my hardware would you recommend not gaming until I grab a new psu. If there is any risk in damaging my 2080 ti I do not want to take it.

Stop using the 80 PLUS rating as a deciding factor.  The efficiency of the PSU does not dictate the quality.

 

 

If you're on a budget because you blew your wad on a 2080 Ti and an Z390, there are some good Bronze and Silver units with LLC resonant topologies and DC to DC that are going to be cheaper than many Gold units.  Bottom line.  There's some good Bronze units and there's some suck Gold units.  80 PLUS is not a gauge of quality.

 

Read (current) PSU reviews.  And, as much as I hate to say it, use the PSU tier list here in the forums.  If you know this little about PSUs, you're a prime candidate for the tier list's usefulness.

I understand efficiency doesn’t dictate quality. I am just curious if using my current power supply can cause damage to my hardware, particularly my 2080 ti. Thanks for the help!

It *shouldn't* cause damage, but the lack of reviews for that particular unit throws that completely into question.  We have no idea what protections that PSU has.

 

More likely you'll see issues like shutting down, rebooting, etc.  Of course, none of this is good for your PC as a whole long term, so at the first signs of that behavior, stop using that PSU.

 

EDIT:  Also, if you get a decent enough PSU, you actually don't even need 750W.  A good quality 650W would work fine with your build.

There is a chance that it could indeed fry the 2080Ti being that it is a questionable PSU at best.

 

If it was me I would remove the Graphics card from the PC until a new high quality PSU is bought. That is my recommendation currently as it's not worth the risk of losing a $1,300 GPU.

 

I would stick with 750W given what you are planning on upgrading to, Z390 and 9700K.

 

The 2080Ti can pull a bit over 350W by itself easy OCed and then the 9700K can pull around 200W OCed, then the rest of the system so to give some headroom 750w would be a good choice. Plus the cable options are generally better on the 750W units, and with 2 EPS (CPU connections).

 

I would say one of these 750W.

 

Corsair RMX 

Seasonic Focus Plus

EVGA G2

 

Or higher end Corsair HX or Seasonic Prime Ultra if you have the budget.


i9 9900K @ 5.0 GHz, NH D15, 32 GB GSKILL Trident Z RGB, AORUS Z390 MASTER, EVGA RTX 2080Ti FTW3 Ultra, Samsung 970 EVO Plus 500GB, Samsung 860 EVO 1TB, Samsung 860 EVO 500GB, ASUS ROG Swift PG279Q 27", HYPERX Alloy Elite KB, Logitech Gaming Pro Mouse, CM Master Case 5, Seasonic Prime Titanium Ultra 750W.
